As the number of non-English-speaking children, entering the school system continues to increases rapidly, teachers have to learn ways to encourage and teach these kids successfully. Relying on their knowledge of how language is acquired, teachers can understand the steps and processes children must take while learning English and help incorporate them into their classroom. Two acronyms that help explain the two types of languages in the school community are BICS (Basic Interpersonal Communication Skills) and CALP (Cognitive Academic Language Proficiency).

This manipulation of their mouth is what allows babies to form an abundance of sounds and eventually words. After a couple of weeks or months, the cooing eventually turns into sounds such as aaa, ooo, and ahh (Otto, 2010). It is during this stage; the phonological awareness starts to take root. The phonological system is described as the system of sound. Phonological awareness is an understanding that words are composed of sound units, and that sound unit can be combined to form words. It is during this process that children learn the sounds and dialect of a language.

Challenges and Opportunities to Implement - MyAssignmenthelp.com

Question: Discuss about the Challenges and Opportunities to Implement. Answer: Journal Article- Prejudice in Schools: Promotion of an Inclusive Culture and Climate by Dessel, A. (2010) Summary In the educational institutions, a welcoming environment which boosts the learning process is crucial in todays society (Shaw, 2018). In this literature review, the execution of programs to diminish prejudice in schools and the difficulties faced in the accomplishments would be discussed. According to the opinion of Dessel (2010) prejudice is the cause of the victimization and provocation in the schools .Its elimination is necessary for success in studies. The awareness of the methods to reduce prejudice can be helpful in decreasing the repressive societal arrangements. Since schools are the places, where the students spend most of the time of their day with their classmates, and learn the basics of their education. So they play a great role in affecting their thought processes and the way they are going to lead their lives to a great extent (Suleymanov, 2015). Assessment This journal article is chosen because it appropriately defines the concept of inclusive culture and is connected to the basics of removing bias from the school culture and system. It is published in the Journal Education and Urban Society and the author has written similar articles in the other journals. It suggests that apart from educating the students , the teachers also have the accountability to maintain a safe atmosphere in which healthy learning takes place .It also reveals the fact that unfortunately most of the new teachers are not ready to work with the students belonging to diversified groups, dialectal and cultural back grounds of the society (Dessel, 2010). Due to this reason, many schools fail to provide a safe accommodating atmosphere in which learning can take place. Reflection This journal article is reviewed because it emphasis on the role of the schools as the main socializing places which provide a chance to interact with the people from different backgrounds. Hence the students learn about differences, resolving their conflicts and how to live peacefully (Ministry of Education, New Zealand, 2014).It suggests that solution to the problem of annoyance, oppression and bias is initiating programs to diminish bullying and ferocity and to develop harmony among the students with various cultural back grounds (Dessel, 2010). Journal Article - Inclusive Education for Social Transformation by Marimuthu, S. Cheong, L. S.(2015). Summary This article is chosen due to its emphasis on the transformation in the attitude of the society and the teachers to treat the students with special education needs in equality with the abled students. According to Marimuthu Cheong (2015) an education campaign for the tutors with respect to inclusive education can extend their ability to deal with diversity. The Teacher Training Program (TTP) aims at enhancing the tutors efficiency in the fields of awareness, assistances and practices, so that they can educate the diversified students in the inclusive classes. Moreover, the training programs consist of the training module comprising of the quasi experimental study utilizing the non-equivalent experimental design. A questionnaire is prepared and evaluated by a five point Likert scale. The independent element is teaching and the dependent elements are competence and readiness. Assessment The article was discussed at the Global Conference on Business Social Science in 2014 at Kuala Lumpur and was published in the Procedia - Social and Behavioral Sciences in 2015. It mainly emphasis on the need of accommodating the disabled students with their normal peers. This research aims at transforming the society and developing the teachers capability to transform the current thinking techniques of the students. The suggested attitude is not to evolve special programs for certain groups but to amplify the thought processes, mechanism and enactments to cover all the students as a whole. The inclusive teaching has become a special education framework and its amplified perception can be seen from the view of human rights (Soriano, Watkins Ebersold, 2017). Reflection This article focuses on the atmosphere in which all the individuals are treated equal and accepted in the society. Participation and Inclusion are compulsory elements for human integrity and to enhance human rights in the society. It is the appropriate article for research on Inclusive Education as it insists on the equality of the disabled and abled children and introduction of the teaching programs which educate the teachers to include the children with special education needs in the mainstream of the society (Bouillet, 2013). Journal Procedia Social and Behavioral Sciences Vol. 172 (2015). Summary The journal named as Social and Behavioral Sciences highlights the different aspects of education including necessity of value education for empowering youth, inclusive education etc. The topic relevant to our study is Inclusive Education. It has been discussed in the journal article Inclusive Education for Social Transformation (Marimuthu Cheong, 2015). The concept of Inclusive Education has gained popularity in all the international education systems. There is an expressed agreement universally that all the children have the right to education irrespective of their cast, creed, background and gender. Due to some reasons, the inclusive education has always been on the secondary priority both in developed and developing countries. The intellect and multiplicity are the features of humans. The notion that a paralyzed person is unserviceable has been assimilated in the society. The separation begins within the family who does not welcome the child with deficiency (United Nations, 2018). Assessment It illustrates that the concept of inclusive education originated due to the evolution of the Universal Deceleration of Human Rights in 1948 which focused on the right to education for every child. Also, the Standard Rules on the Equalization of Opportunities for Persons with Disabilities in 1993 drew the attention of the world towards right of education of children with special needs. Hehir et al. (2016) suggests that the inclusive education should be child focused and should address the diversity of his background. Reflection This Journal aims at integrating children with Special Education Needs into the mainstream schools. It has been selected for review as it highlights that Inclusive Education is an international campaign in the arena of education. This concept introduces a change in the thinking within the education mechanism and the society. The tutors should understand that it is about transformation in the outlook and the methodology of teaching. Not much data is accessible for teaching representations for inclusive education. All the disabled students do not always require the similar education. So, there is no need of segregating the disable students into different schools. So, this article includes the accountabilities of the tutors as well as transformation in the teaching techniques, so that the disabled students are accepted in the mainstream of the society (Australian Research Alliance for Children and Youth, 2013). Journal Education and Urban Society Vol. 42 (2010) Summary Education and Urban Society (EUS) is the Journal for sharing new philosophies on educational procedures, researches and policies. It emphasizes on the interrelationship between teachers and students. It provides an interface for enabling communications among teachers, administrators, school boards and sociologist. The topics covered in this journal are the Reform in the Urban School Districts: the role of PSAT results in promoting advanced placement course taking and Measuring academic growth in students with disabilities in charter schools etc. The topic relevant to our research is Prejudice in Schools: Promotion of an Inclusive Culture and Climate (Dessel, 2010). The main idea behind inclusion is to remove the limits and evolve the education system which is designed as per the needs of the students. Assessment This journal has been selected for research as it argues that the current education concepts regarding inclusive education are based upon certain features such as age, and the ability of the students to attend the classes. The availability of prospects, acceptance of impairment and the nonexistence of annoyance, oppression and bias set the background for inclusive education in classes. According to Wapling (2016) the schools should make sure that there should be a common education system for all the students irrespective of their physiological, psychological, social, emotional and linguistic circumstances. Also as per No Child Left behind Act, the schools are required to show the continuous development in the performance of the students especially the disabled students. So, they face challenges in meeting the performance standards which should be resolved. Reflection This journal highlights that inclusive education involves the cooperation of the society as a whole. It suggests that the educational institutions and the tutors should evolve creative solutions to the challenges faced by inclusive education. Developing the atmosphere which enables the learning of the students and addresses to all their needs can help them in achieving societal, psychological and physiological progress. Hence, the educational institutions should endeavor to evolve creative solutions to the problem of inclusive education (Mitiku, Alemu Mengsitu, 2014). A mechanism to evaluate the results of the implemented programs for the development of the skills of the teachers for inclusive education should be initiated and should be monitored continually.

ACT Reading vs SAT Reading Which Is Easier

ACT Reading vs SAT Reading Which Is Easier SAT / ACT Prep Online Guides and Tips Which is the harder section, ACT Reading or SAT Reading? We will break down the differences between SAT and ACT Reading to help you decide which section is harder for you. You might be surprised which one is easier! Major Differences Between SAT Reading and ACT Reading In this section, I'll break down the most critical differences between SAT Reading and ACT Reading. One test is not inherently easier than the other - it all depends on your skills. Keep your own strengths and weaknesses in mind as you read through the following sections. #1: Breaking Down Long Passages The ACT doesn’t always give line numbers in the questions. For what we call â€Å"little picture, find the detail† questions, you have to skim the whole reading passage to find the answer, whereas SAT always gives line numbers. See an ACT example below: Via ACT's Preparing for the ACT guide. For this question, you have to sift through the passage to find the one line that mentions this very particular detail. If you don't have a good memory for small details, this can take time. In contrast, you can approach the SAT Critical Reading section by reading the questions first and then going back to parts of the passage using the line numbers. For the ACT, you will have to at least skim the entire passage, even if you read the questions first. Our advice? If you have a good memory for longer passages and small details, you will have an advantage on the ACT. If you are good at picking information out of a passage, you might do better on the SAT. #2: Timing Timing is a bigger challenge on the ACT, as the ACT asks more questions per minute.SAT Reading has 52 questions in 65 minutes, giving you 75 seconds per question. On the other hand, ACT Reading has 40 questions in 35 minutes, which gives you just 52 seconds per question.This may not seem like a major difference, but all those extra seconds really add up when you're struggling to answer all the questions in a section before time is called. Keep on your eyes on your watch! Our advice? If pacing and answer questions quickly is a problem for you, you may find the time constraints of the SAT Reading section more manageable. #3: Evidence-Support Questions Are you good at pinpointing specific areas in texts that support your answers to questions? If so, the SAT may be a better fit for you. Evidence-support questions are a big part of SAT Reading but don't appear on ACT Reading. These questions build off of the questions that come before them and ask you to cite specific lines or paragraphs as evidence for your answer to a previous question. Here’s an example of an evidence-support question (with the question to which it's referring): As you can see, these questions can be challenging because theyrequire higher-level thinking and strong reasoning skills. If you're stuck on the first question, you likely won't get the second one right either. Our advice? If you struggle with interconnected questions or having concrete reasons for selecting a certain answer, you may find the ACT easier since it's Reading section doesn't include these types of questions. So Which Test Should You Take? The best way to decide which reading section you’ll do best on is to take real practice tests. Score yourself, and find out which test you score higher on based on percentiles. Also, based on those practice tests, figure out your weaknesses. Are you struggling on SAT’s evidence-based questions? Then the ACT might be a better choice for you. Are you struggling with finishing the ACT Reading section in time? Then maybe the SAT will be a better fit for you. Another strategy is to think about which test you like more. Sure, a test is a test, but you’ll probably find you enjoy one more than the other, and you may study more effectively for the test you like better. Finally, think about the other sections if you can't decide. For example, you might take a practice test and figure out you are slightly better at ACT Reading. But if ACT Math is really hard for you, it could cancel out the benefits of being better at ACT Reading. What’s Next? Want a comprehensive guide to whether the ACT or SAT is easier? Read this detailed breakdown. In this post we recommended taking a practice ACT and practice SAT reading sections to figure out your strength. Check out our links to free ACT and SAT practice tests to get started! What about the writing and math sections?

The Concept of Demoralisation

The Concept of Demoralisation Free Online Research Papers ‘Demoralisation’ is a concept which encompasses the perceived declining morality of individuals in modern western society. Western society’s obsession with the economy, profits and efficiency had supposedly lead to the extinction of morals. I shall consider different viewpoints and contemporary examples to determine the extent to which this viewpoint holds truth. Firstly, I shall look at Weber’s formal rationality and Ritzier’s ideas of dehumanization, referring to Bauman’s example of the Holocaust as evidence of severe demoralisation. I shall then examine Bauman’s writings on Postmodern Ethics and how society acts to constrain our morals. Durkheim’s Anomic Suicide provides a deeper understanding of the extent of society’s regulation and then I shall consider Mestrovic’s account of the deregulation of the economy. Finally, I shall reflect on Ralph Fevre’s more contemporary description of the misapplication of rationality and how this acts to demoralise individuals. In order to grasp the extent of the infiltration of declining ethics into our society, I shall consider the presumed cause of this situation. Rationalisation and the rise of capitalism are the core changes which have shaped individuals morals and behaviour in the modern western world. Max Weber is the key advocator of this position in his formulation of his ideas on the rationalisation process and bureaucracy. Bureaucracy refers to a method of organisation where all action is specifically regulated by rules formulated by officials. These rules attempt to shape society in a way which eliminates chaos, free-thinking and choice in order to achieve a rational and efficient society. Weber developed the idea of ‘formal rationality’, a key component of bureaucratic organisation, which refers to the rationalised principles individuals rely on in decision-making. Institutionalised rules curb the actions of individuals to aid them to a specific end, eliminating any reference to values or morals. Weber stated that formal rationality sees the ‘discharge of business according to calculable rules and without regard for persons’ Ritizer highlighted one of the key dimensions of rationalisation as the control it exerts over people. Human judgment is replaced by rules, regulations and structuresThis dehumanising aspect of bureaucracy links to Weber’s concern about the irrationality of rationality which Ritzier discusses in his analysis of McDonaldisation. Ritzier turns to Ronald Takaki to demonstrate how rationalised settings can act as places in which the ‘self was placed in confinement, its emotions controlled, and its spirit subdued’ (Takaki cited in Ritzier 2004:25). Here, Ritzier is showing how despite the effectiveness of bureaucracy, the rationalised processes can act to dehumanise and alienate individuals. Bureaucratic procedure therefore acts to demoralise individuals and places people into, what Weber calls, the Iron Cage of rationality. By this, he is referring to the extent to which bureaucracy and rationalisation dominates mankind; rather than viewing this as a step towards freedom, Weber maintains that civilization is becoming increasingly enclosed in an â€Å"iron cage†- and this acts to enclose and reduce our moral freedom. Whilst Weber’s views on the deterioration of morals in our society can be appreciated, it is nevertheless necessary to examine some present values compared to those of the past. All Western societies operating under capitalist principles provide some degree of welfare benefit with the generally accepted moral stance of care and concern for the disadvantaged. However, in the pre-capitalist societies of the 18th Century and beyond, the basic rights of health care and education for all were not considered essential. If morality can be defined as the concern with right or wrong behaviour, then there is a need to question Weber’s implication that moral attitudes pre-capitalism were intrinsically superior. The principle example of Weber’s fears of rationalisation infiltrating into civilian life was highlighted by Zygmunt Bauman, who showed how the events of the Holocaust demonstrated precisely the demoralisation invading our society. Bauman was concerned with the apparent dismissal of the Holocaust as a one-off event, a momentary lapse of morals from one prejudice group. His belief was that the distinct lack of moral instincts were due to a malfunction of society; viewing the causes of the actions as due to the rationalisation of bureaucracy. Bauman proposed to ‘treat the Holocaust as a rare, yet significant and reliable, test of the hidden possibilities of modern society’. The precise bureaucratic procedure carried out by the Nazis in the mass-murder of innocent individuals, demonstrated the extent to which modern civilization was, according to Bauman, the Holocausts necessary condition (Bauman 1989:13). The rationality described in detail in Weber’s writings focused on specific elements in society which can be directly seen in the processes of the Holocaust; the rational spirit, efficiency and the regulation of values. Bauman even believed, after re-reading Weber’s analysis of modern society in light of the Holocaust, that the event could have even been predicted by Weber himself! The concept of demoralisation was important to Bauman as he posed the question of how normal individuals can be transformed into the perpetrators of mass crime. For him, the bureaucratic organisation of the Holocaust resulted in the social production of moral indifference and the concealment of morality in actions. Moral indifference occurred as the perpetrators were under complete authority by a movement they were devoted to. The procedures which were undertaken were regulated and ordered into a routine, dispensing with moral obligations. The victims of the Holocaust were also dehumanized through the use of ideology, by demeaning the victims to a non-human state; the full implication of the perpetrators actions would not be acknowledged. Demoralisation was also achieved through the ‘mediation of action’, where the casual connections between the actions of the perpetrators and the mass murder itself was concealed. Bauman demonstrated how the methods of killing increased the distance between the acts themselves and their consequences. Though the use of gas chambers, one individual was not responsible for another’s death in the way shooting an individual would harm morale. Instead, the jobs of building the chambers themselves, parading the victims into the rooms and emptying the chemicals into the roof were divided between many individuals; and therefore so was the responsibility. Bauman successfully demonstrates the way in which bureaucratic procedure is mirrored within the procedures undertaken by the Nazi’s, however rationalisation in society may not be the sole cause of this event in history. The suspension of moral outrage by the people who participated in the Holocaust was possibly created though fear of the repercussions of opposition. There are examples of equivalent atrocities throughout modern history and there is scant evidence to suggest that bureaucracy was the root cause of their creation. The regimes of Hitler, Stalin, Idi Amin, Chairman Mao and Magabe are linked by their dictatorships, subsequent misuse of power and the imposition of a climate of fear which was necessary to subjugate their people. No modern western society is presently ruled under a dictatorship, it relies on a collaboration of opinions and the co-operation of society. The expression of opinions does not result in punishment as there is a toleration of free expression; and this toleration could be considered as an aspect of morality. Bauman focuses specifically on ‘demoralisation’ in his writings on Postmodern Ethics (1993) where he considers the link between post-modernity and morals. Demonstrating distress for the postmodern ‘substitution of aesthetics for ethics’ he exposes how the ‘right way’ is no longer a simple path to take, postmodernity has developed numerous divides of being ‘economically sensible’, ‘aesthetically pleasing’ and ‘morally proper’ Bauman draws on Weber’s writings of the Protestant Ethic and how their compulsive emphasis on morality seeped into all aspects of life. Now, the moral guidance of the church is almost extinct and so modern legislators are attempting to ‘compose and impose†¦ a cohesive code of moral rules which people could be taught and forced to obey’ This demonstrates the imposition of rationality on morals, no longer is morality a personal righteous decision, as free will is viewed with such caution by those in control that enforcement of what is right is essential; ‘untoward, potentially heinous impulses needed to be held in check’ . Weber’s formal rationality appears to be enforced even in our inner most decisions. In Bauman’s opinion, rationality cannot take precedence over moral impulses, it merely can ‘silence it and paralyze’ and would therefore lead to less good being done than would otherwise have been the case. Bauman maintains that morals are precisely non-rational, the morality of a choice is lost if the choice involves a calculation of gains and losses. He advocates that only rules are universal; therefore morals should be ‘thoroughly personal’, detached from any form of rationality as true morals should rest on personal responsibility. Bauman draws on Durkheim’s view of ‘anomie’, explaining that one can only be moral when alone and not subjected to the influence of society, as this is when ‘moral impulse makes an exit’ Bauman is therefore stating that ‘morality is the condition of perpetual and irreparable anomie’ In order to gain a deeper insight into Durkheim’s formulation of ‘anomie’ and its link to the concept of ‘demoralisation’, I shall consider his writings on Anomic Suicide. Durkheim formulated the idea of the state of anomy in his considerations of the influence of both economic crises and ‘fortunate crises’ on suicide rates. Massive setbacks in the economy can be linked with high suicide rates, and this would presumably lead to the assumption that if circumstances were to improve then the rates of voluntary deaths should decrease. Durkheim provided evidence to show that this was, however, not the case. He examined the situation in Rome in 1870, where a spurt of economic growth lead to an increased standard of living for the whole of society. Despite this prosperity, suicide rates soared, shattering the presumed link between poverty and suicide rates. Durkheim perceived these high suicide rates to be linked to ‘disturbances of collective order’ and formulated his concept of anomy. Man has, according to Durkheim, material and selfish desires which provide humans with an ‘inextinguishable thirst [which] is constantly renewed torture’ In order to ever be satisfied or content, these passions require limitation and Durkheim believes that it is society which takes on this ‘moderating role’. Society provides individuals with a set of ideas concerning their upper limit of achievement and this will usually be an accessible goal, thus leading to contentment and happiness within individual circumstances. Anomy occurs when society is ‘momentarily incapable of exercising this influence’ and the individual is thrown into a deregulated state which has no limits to bind them. Both economic disasters and increases in wealth can act to upset the scale, and force individuals into a state of anomy. The severe consequence of this state, for Durkheim, is the incident of voluntary death. Bauman was suggesting that it is only in this state where true morals exist as this is when society loses its dominance over individuals. True free-will and independent thinking from the constraints of society, provides individuals with the ability of pure moral thought. However, Durkheim’s formulated relation between anomy and high suicide rates demonstrates the extent to which modern society constrains us. If the release from influence is so huge that it forces individuals to take such extreme action as death, then it would appear that some restraint is beneficial and thus would be instinctively sought by civilized society. Stjepan G. Mestrovic in his book The Coming Fin de Siecle (1992) applies Durkheim’s anomie to the deregulation of the economy, and demonstrates demoralisation with particular focus on the economy and its infiltration into all spheres of social life. Both modernity and post-modernity have resulted in a reconstruction of society which is in accordance with purely economic interests. Durkheim was concerned with how this exposes society to extreme risks of anomie, as economic crises can therefore impact on all in society in one way or another. â€Å"Precisely because the economic functions today concern the greatest number of citizens†¦It follows that as that world is only feebly ruled by morality, the greatest part of their existence takes place outside the moral sphere† Mestrovic focused on how the news in the 1980s directly portrayed Durkheim’s observations that the economic anomie is a major cause of the public’s lack of moral standards, as it showed reports of a clear decline in business ethics. Durkheim had anticipated the postmodernist ‘success at any cost’ ethic due to society’s obsession with improving the economy and this was unfortunately demonstrated in a number of cases. The Stock Market crash of 1987 had severe effects of demoralisation. Lack of confidence joined with periods of unemployment, welfare dependency and a sense of panic resulted in a demoralised work force meaning that regaining credibility and public trust proved difficult. ‘The economic sphere of life’ previously came second to religious or political life, however now it is such a vast aspect of society it dominates all of social life and acts to alter the actions of individuals. Modern social institutions are now, according to Mestrovic, run as if they were businesses. A key example of this are modern churches, in previous eras churches were simple and sustained from donations and charitable contributions whereas now, Mestrovic exposes how they invest in stocks and hire secretaries to increase credibility and in some cases, profit. The fear is that the domination of the economy within all social institutions can lead to the influence of economic anomie throughout society. Durkheim highlighted that due to this social change, the infiltration of immorality will be more invasive and total. Mestrovic was particularly concerned with demoralisation as he highlighted the three most ‘pressing and controversial modern social problems’ as the lack of business ethics, the selfishness of the ‘me generation’ and the rise of hyper-individualism. The lack of morals which is associated with the cut-throat business world is now seeping into all of social life as the economy becomes increasingly dominant and powerful. To illustrate the way in which Durkheim’s economic anomie is infiltrating throughout modern society, Mestrovic drew on the events following the Stock Market crash of 1987. Firstly, bankruptcies were reported to be extremely high both before and after the Stock Market crash and it is evident that Durkheim stated that bankruptcies can be an indicator of anomie. And secondly, Durkheim stated that ‘When the price of the most necessary foods rise excessively, suicides generally do the same’ and just after the Stock Market crash there were surges in prices for wheat and corn, demonstrating the presence of anomie. Mestrovic concerned himself with the reasons why such mounting evidence of demoralisation have been ignored; he demonstrated that it was not only Durkheim who highlighted the infiltration of immorality from the economic sphere, major influential writings such as the critiques by Simmel in his Philosophy of Money and Marx’s analysis of capitalism demonstrate similar postulations. Mestrovic believed that such links have been ignored for ideological reasons. Post-modernity prevents the study of an idea which demonstrates the ‘instability of human desire-anomie’. The realization of such a concept in a post modern society could disrupt the bureaucratic system and the rationale on which it is based. However, is the business world as cut-throat as Mestrovic is implying? Modern day businesses are now centered on policies which enforce environmental responsibility, fairness towards employees and the provision of responsible services to customers. Ethics within the business world appear to be foremost on agendas, as implementing morale within a work force is vital to ensure the well-being of employees. Although the underlying element is still increasing efficiency and profit, employees are cared and provided for by benefits and services. A key objective for companies is to raise the morale of employees to inadvertently increase business status and profits. The question which arises here is whether morale has in fact taken the place of morality? (A point made by David Riesman in the 1950s). Ralph Fevre, in his book The Demoralisation of Western culture, is particularly concerned with what has taken the place of our ‘hollowed-out’ morality. Drawing on Riesman’s idea of the replacement of morale with morality, Fevre demonstrates how Riesman believed demoralisation had occurred as individuals relentlessly followed the crowd for guidance on values and discovering the ‘right way’ of doing things. Riesman perceived how individuals no longer exercise autonomy in decision-making. In relation to business, the replacement of morality with morale would be beneficial to a rational business system. Autonomy in choices could potentially lead to chaos and irrationally, which bureaucracy is compelled to avoid at all costs. By subjecting employees to a specified morale, limiting choices and moral consideration, order and efficiency can be achieved. Ralph Fevre provides an up-to-date consideration of the issues surrounding demoralisation, directly contemplating its influence on Western society. In his opinion, common sense is the form of reasoning which has led to our demoralisation and has taken the place of morality. Common sense is the ‘general level of knowledge which may be derived from a variety of sources’ but, Fevre, in addition to this, explains that common sense also has a ‘sense-making function’ which appeals to our confused state in relation to our limited access to morality. Emotions and religious feelings previously guided our actions, meaning that decisions were made from a basis of moral integrity. Now, common sense appears to be a more â€Å"reasonable† guide for our actions; ‘it is now established as the standard by which we believe we are required to explain ourselves. Emotions have become vacant because they are no longer considered to be a reliable basis for reasoning. Common sense, on the other hand, is in conjunction with our rational society as it relies on hard evidence, through senses and experience, to explain things. Common sense therefore demotes emotions to ‘useless sentiment which can simply be expressed but never acted upon’. In society’s adoption of common sense as our sole form of reasoning and in the disregard of emotions, morality ceases to exist in numerous aspects of our lives. Fevre therefore places the blame of demoralisation on our reliance on common sense in reasoning. Fevre holds that an individual’s application of rationality and reason is occurring in the wrong place and as a result demoralisation occurs . Through our experience of society, rationality does prove successful in business and in achieving certain aims. The richest people of the world are particularly aware of this, as it may be the rational processes and scrupulous efficiency that gained them their riches and status. It is not a coincidence therefore that a common conception of rich people is their unhappiness as a result of their ‘losing touch with fundamentals’. The perceived effectiveness of rationality seeps into all aspects of life, demoralizing all where it is applied- particularly in relation to personal relationships. Fevre demonstrates his argument by use of an example of a widespread dilemma concerning childcare; whether to continue working and pay for childcare, or to abandon work and stay at home to look after the children. If the dilemma is considered with reference to a cost-benefit calculation and treated as a purely economic decision, as opposed to being considered with the moral reference it deserves, then the application of rationality is inappropriate and morality is lost. Fevre accepts the difficultly of such a situation and that ‘whatever we decide, we are left with feelings of doubt and unease’ but he is demonstrating what demoralisation feels like as ‘in our hearts we know we have put our children into an instrumental calculation and weighed their worth’ Our most intimate, personal and moral decisions are now, in modern western society, being considered with the structure and processes used in the business world- as this is all we know. We strive for efficiency and rationality to such an extent that we no longer know how to apply morality and emotions to day to day decisions. Demoralisation is a negative consequence of the way our economy and our society has been built, but there are key positive consequences of our development. Efficiency and rationality has provided us with a strong and reliable structure which has enabled us to gain from a high standard of living. Profit provides us with money which is required for survival; giving us access to basic needs such as food, shelter and health provisions- therefore is profit really such a dishonorable term? From a negative viewpoint, profit motivation has lead to the exploitation of labour in developing countries as the western world seeks to cut expenses and gain access to cheap commodities and services- we utilize their poverty for our own interests. This is an example of severe demoralisation, as despite this fact of which we are all aware, we relentlessly continue to buy into such services for a more â€Å"reasonable† price to increase our own means. Profit is consistently sought after, however much we wish to prevent any exploitation; our economy has meant that exploitation has become inevitable. This demoralizes modern western society as a whole. In conclusion, demoralisation is a concept evident in many areas of society. Weber and Durkheim predicted the suspension of morality in a bureaucratic society and contemporary examples have demonstrated the truth of their insights- The key issue is whether it is a necessary evil, the unavoidable product of the way in which modern western society has been developed. The question posed to our society is whether morality can return.

The cherry blossom is particularly important in Japanese culture as it represents the end of the winter and the being of new life and growing season of spring† (Japanese Lifestyle, par. 1). Remarkably, despite the tragic event of the earthquake that instigated a tsunami in Japan on March 11, the remaining cherry blossom trees continue to bloom and became symbols of both fragility and courage. As Sakurai indicated, â€Å"the warrior class liked the flowers because they didnt cling to life, but rather showed up for the briefest spell, and fell at the peak of their splendor. In this way, they embodied the spirit of "bushido" — the way of the warrior that combines stoicism, bravery, and self-sacrifice† (par. 7). By this, I was convinced that the event would be a worthwhile and memorable experience. The NCBF in Washington, D.C. has events lined up since February to April of 2011, showcasing arts exhibition of different seasons in Japan, an exhibition of flower

Utilisation of Wind Energy for High Rise Building Power

Utilisation of Wind Energy for High Rise Building Power Introduction The price of conventional energy is on the rise, due to the ever-widening gap between demands and supply. The main reason for such shortages is the depletion in natural resources, such as coal, which is the main fuel used for electrical energy generation. Since these fuels are made up of carbon compounds, burning them has rapidly increased the amount of carbon dioxide in the atmosphere over the last 100 years. This has brought about a chain reaction of hazards such as global warming, climate change, destruction of ecosystems, etc with predictions for adverse outcomes in the future. In response to this threat and to initiate an end to such processes, the UN agreed the Kyoto Protocol in Japan in 1997. This requires industrialised nations to reduce greenhouse gas emissions by 5% of 1990 levels by 2008-2012. The UK has agreed to meet this target and furthered its promise by setting a goal of 50% reduction in carbon emissions by 2050[ ]. Part of its government energy policy is to increase the contribution of electricity supplied by renewable energy to 10% by 2010 (Blackmore P, 2004). A similar promise has been undertaken by many world nations, which has led to a plethora of new and innovative methods for power generation. Renewable is the key to climate friendly forms of energy, due to the absence of emissions detrimental to the environment (Stiebler M, 2008). It includes energy derived from sunlight, wind, wave, tides and geothermal heat. Out of the afore mentioned resources, geothermal heat is restricted to only limited locations on the globe while wave and tidal power is still in its research stage. Thus sunlight and wind are the key elements that can be tapped for energy generation. However, on comparison between the two systems, wind energy systems are more advantageous both in availability of resources and cost of generation. This report mainly focuses on wind energy, with a keen interest on harvesting it for ventilation and power generation purposes in high-rise buildings. Plan forms that aid this purpose will be studied using Computational Fluid Dynamics to understand the flow of wind in and around a thirty-storey structure and the building configuration well suited for natural ventilation and wind turbine integration would be identified at the end of the test. To obtain a complete picture of wind flow patterns and to closely mimic real life situations, the wind will be simulated from different directions at different wind speeds. Wind energy Wind is the term used for air in motion and is usually applied to the natural horizontal motion of the atmosphere (Taranath Bungale S, 2005). It is brought about by the movement of atmospheric air masses that occur due to variations in atmospheric pressure, which in turn are the results of differences in the solar heating of different parts of the earth’s surface (Boyle G, 2004). At a macro level wind profile differs from place to place depending on geographic location and climatic conditions while in a microstate the immediate physical environment of a particular place modifies the nature of the winds. For example, the velocity of the wind recorded in the countryside which has acres of unobstructed grassland would be greater than that recorded in a city dominated by skyscrapers. Hence to obtain a clear idea of the wind characteristic corresponding to a particular area the wind rose is utilized. They are based on metrological observations and depict the varying wind speeds experienced by a site at different times of the year together with the frequency of different wind directions [ ]. It is the first tool consulted to judge the wind resources of a site and its ability to support power generation. The winds have been tapped from ancient times by means of ship sails, windmills, wind catchers, etc. The history of windmills goes back more than 2000 years (Stiebler M, 2008) when they were predominantly used for grinding grain and pumping water. However, the breakthrough occurred when Charles.F.Brush erected the first automatically operating wind turbine at Ohio in 1888 [ ]. It was fabricated using wood and had a rotor diameter of 17m with 144 blades. The system recorded very low efficiency and was mainly used to charge batteries. The reason behind the poor efficiency was due to the large number of blades, which was later discovered by Poul la Cour who introduced fewer blades into his wind turbine. Though such developments were achieved at an early stage in innovation, it was not until 1980 that the prominent application of renewable energies was sought after (Boyle G, 2004). Wind energy is the harnessing of the kinetic energy prevalent in moving air masses. This kinetic energy for any particular mass of moving air (Boyle G, 2004) is given by the formula: K.E = 0.5mV ² where, m – mass of the air (kg) and V – wind velocity (m/s). However this mass of moving air per second is: m = air density x volume of air flowing per second m = air density x area x velocity   Thus, m = rAV where, r – density of air at sea level = 1.2256 kg/m ³ and A – area covered by the flowing air (m ²) Substituting this value of m in the former equation, K.E. = 0.5rAV ³ (J/s) But energy per unit of time is power and hence the above equation is the power available from the wind. It is also evident that the power is directly proportional to thrice the wind velocity. In other words even a marginal increase in wind speed would yield three folds of the nominal power. This is the critical fact based on which the whole energy process is evolved. However not all of this power can be exhausted since it would lead to nil outflow through the wind turbine, that is no flow of air behind the rotor. This would lead to no flow of air over the turbine causing total failure of the system. According to Albert Betz the maximum amount of power that can be harnessed from the wind is 59.3%. This is often referred to as the Betz limit and has been proven by modern experiments. Some of the advantages of wind energy include: It is based on a non-exhaustive resource and hence can be harnessed for generations. It is a clean and eco friendly way of producing energy. In its working lifetime, the wind turbine produces eighty times the amount of energy that goes into its manufacturing and thus has diminishable net impact on the environment. It does not require any additional resources such as water supply unlike conventional power generation. It can boost the economy of the region (wind farms). Wind turbines: Wind turbines are the modern day adaptations of the yesteryear windmills but unlike their counterparts they are mainly used for power generation. These new age systems come in different shapes and have various configurations, the well established of them all are the Horizontal axis wind turbine and the Vertical axis wind turbine. Write a brief about horizontal wind turbines and vertical wind turbines. BUilding integrated Wind Turbines (BUWT): Building integrated wind turbines are associated with buildings designed and shaped with wind energy in mind (Stankovic S et al, 2009). They are relatively a new way of harnessing energy that is gaining popularity at a quick pace. Small scale wind turbines on house roofs and retrofitting also fall under this category. The design of BUWTs is a complicated affair and involves the careful consideration of various factors. Since turbines are fixed into the building’s fabric its impact on the environment, building’s response and needs of its owners and occupants need to be weighed equally. Also numerous design decisions such as planning, structure, services, construction and maintenance depend on this single process (Stankovic S et al, 2009). With the increase in the scale of the proposal the importance of these factors increases simultaneously. The proposal generally spans from the number, scale, type and location of the turbines together with its annual energy yield and design life. A good BUWT based building should be a wholesome design that does not prejudice the buildings efficient functioning for energy generation. Generic options for BUWTs: Stankovic S et al (2009) explains that the wind turbines can be fixed on to a building in enumerable ways. Each method can accomplish a different level of power depending on the type of turbine used and the form of the building it is mounted upon. On top of a square/ rectangular building: This configuration is on the principle that the wind velocity increases with height and hence the amount of energy generated would be of a higher order (10% increase with wind acceleration). An added advantage is that the turbine would experience relatively little turbulence. But access to the turbine for maintenance and decommissioning works may be difficult. If mounted on tall buildings the turbines may threaten the visual quality of the skyline. On top of a rounded building: This case is very similar to the previous configuration except that with the use of rounded faà §ade the mean tower height can be considerably diminished. Also the rounded profile influences the local acceleration (15% increase in energy). The low tower height favors easy access to the turbine but leads to blade flicker and noise issues. Concentrator on top of a rounded building: This case is well suited to areas with bi-directional winds (20% energy increase over a free standing equivalent due to local acceleration). Vertical axis wind turbines are better suited for this feature while Horizontal axis wind turbines need to be suitably altered to achieve the same status. The building spaces that act as concentrators may be inhabited with suitable acoustical treatment. This case also encounters the same drawbacks as listed in the previous case. Square concentrator within a building faà §ade: As before, this configuration takes advantage of the higher quality winds at higher altitudes and local acceleration thereby achieving 25% increase in energy and 40% increase for bi-directional winds. This option is best suited for buildings with narrower profiles. There may be a loss in the saleable area of the building but the aperture can be converted into an exclusive feature such as a sky garden. The opening also relieves the wind loading on the building’s facade leading to simpler structural solutions. Vertical axis wind turbine is the only choice for integration due to its square swept area. Circular concentrator within a building faà §ade: This is very similar to the square concentrator except the opening is accustomed to hold pitch controlled horizontal axis wind turbines with fixed yaw. Also, a 35% increase for uniform wind and 50% increase in energy for bi-directional winds are achievable in this method. But on the down side, this technique is more expensive due to the cylindrical shroud. On the side of a building: In this technique, an increase in 80-90% in energy than the freestanding equivalents is achievable only if the building form is optimized to the local wind character. Only reliable vertical axis wind turbines can be used for power generation due to access issues. For higher swept area, more number of turbines should be used. Between multiple building forms: This type of an option opens out many doors for a range of architectural forms. Unlike the previous cases, the buildings orientation, form, shape and spacing play key roles in the performance of the turbines. Vertical axis wind turbines are better suited for this purpose. Guidelines for BUWT’s: The following are some guidelines outlined by Stankovic S et al (2009) for incorporating wind turbines into a structure: BUWTs should be tailored to the specific site for good results. Adequate wind resources should be available on site. If however if the site is under resourced steps are to be adopted to deliberately elevate the quality of the wind through the buildings form or turbine. The impact of its surroundings should also be considered before commissioning such a project. The dominating wind direction and its intensity should be observed from meteorological data. This would help in determining the form and orientation of the building together with finalizing the position of the wind turbine to make the most out of the available resource. Environmental impact assessment corresponding to the site should be carried out to foresee the adverse effects the turbines may create. Acoustic isolation may be sought for in some areas within the building if it lies at close proximity to the rotor. Natural ventilation and day lighting qualities of the building may be challenged and forced to settle for artificial means. The type and position of openings, external shading devices, smoke extracts etc should be handled with appropriate care to avoid draught winds. Access to the wind turbines for maintenance and decommissioning must be provided suitably. The aesthetic quality of the mounted turbines must harmonize with its surroundings and should not over power the pedestrians at ground level. To this end well suited screening devices such as canopies, screens and landscape may be utilized as per the necessity. The overall success of BUWT project depends on its ability to deliver the expected power. Inability to comply with this effect would result in the failure of its intended purpose from both an environmental and design point of view. Thus the electricity demand of the building and the level to which this would be met with should be estimated prior to turbine design to secure maximum benefits. Wind flow prediction and energy yields: For any project to be successful, Wind flow and building design (Taranath Bungale S, 2005) When the air moves in a vertical direction it is referred to as a current. These currents play a major role in meteorology whereas the gradual decrease in wind speed and high turbulence of the horizontal motion of air, at the ground level, are vital in building engineering. In urban areas, this zone of turbulence extends to a height of approximately one quarter of a mile aboveground and is called the surface boundary layer. Above this layer, the horizontal airflow is no longer influenced by the ground effect. The wind speed at this height is known as the gradient wind speed, and it is precisely in this boundary layer where most human activity is conducted. Characteristics of wind: The flow of wind is complex because many flow situations arise from the interaction of wind with structures. A few characteristics of wind include: Variation of wind velocity with height: The viscosity of air reduces its velocity adjacent to the earth’s surface to almost zero. A retarding effect occurs in the wind layers near the ground, and these layers in turn successively slow the outer layers. The slowing down is reduced at each layer as the height increases, and eventually becomes negligibly small. The height at which velocity ceases to increase is called the gradient height, and the corresponding velocity, the gradient velocity. At heights of approximately 366m aboveground, the wind speed is virtually unaffected by surface friction, and its movement is solely dependant on prevailing seasonal and local wind effects the height through which the wind speed is affected by topography is called the atmospheric boundary layer. Wind turbulence: Motion of wind is turbulent and it occurs in wind flow because air has a very low viscosity-about one-sixteenth that of water. Any movement of air at speeds greater than 0.9 to 1.3 m/s is turbulent, causing air particles to move randomly in all directions. Vortex shedding: In general, wind buffering against a bluff body such as a rectangular building gets diverted in three mutually perpendicular directions. However, only the longitudinal winds and the transverse winds or crosswinds are considered in civil engineering. When a free flowing mass of air encounters a building along its path, the originally parallel upwind streamlines are displaced on either side of the building. This results in spiral vortices being shed periodically from the sides into the downstream flow of the wind, called the wake. At relatively low wind speeds the vortices are shed, that is, break away from the surface of the building and an impulse is applied in the transverse direction. Distribution of pressures and suctions: When air flows around the edges of a structure, the resulting pressures at the corners are much in excess of the pressures on the center of elevation. This has been evident by the damages caused to corner windows, eave and ridge tiles, etc in windstorms. Wind tunnel studies conducted on scale models of buildings indicate that three distinct pressure areas develop around the building. They are: Positive pressure zone on the upstream face (Region 1) Negative pressure zone at the upstream corners (Region 2) Negative pressure zone on the downstream face (Region 3) The highest negative pressures are created in the upstream corners designated as Region 2. Wind pressures on a buildings surface are not constant, but fluctuate continuously. The positive pressure on the upstream or the windward face fluctuates more than the negative pressure on the downstream or the leeward face. The negative pressure region remains relatively steady as compared to the positive pressure zone. The fluctuation of pressure is random and varies from point to point on the building surface. Nearby buildings can have a significant influence on wind forces. If they are the same height as the structure being considered then they will mostly provide shelter, although local wind loads can be increased in some situations. Where surrounding buildings are significantly taller they will often generate increased wind loading (negative shelter) on nearby lower structures. Shelter can result from either from the general built-environment upwind of the site or from the direct shielding from specific individual upwind buildings (Blackmore P, 2004). Natural ventilation The three natural ventilation airflow paths in buildings are (Pennycook, 2009): Cross ventilation Single-sided ventilation Passive stack ventilation Advantages of cross ventilation: Greater rates of ventilation can be achieved under amicable weather conditions. Can be utilized for deep-plan spaces with operable windows on the external wall. Incumbents have control over ventilation. Relatively cost free. Can be incorporated with thermal masses. However, it has certain limitations such as: Internal space layout must be hindrance free for easy, clear flow of air. Internal partitions must be within 1.2m height and tall cupboards must be placed alongside the windows. Natural ventilation can occur only under the presence of suitable winds. Poor planning and positioning of windows may cause disruptive draughts and gusts. Winter ventilation is problematic. Unsuitable for buildings located in noisy and pollution prone environments. The requirements of fresh air supply are governed by the type of occupancy, number and activity of the occupants and by the nature of any processes carried out in the space (Koenigsberger et al, 2001). When natural ventilation is stipulated for good indoor air quality, the amount and nature of the dominant pollutant source in the space should be identified. Based on this data the ventilation rate for the space can be calculated such that the pollution level does not cross a preset specific mark. Generally the concentration of the pollutants decreases with the increase in airflow rate (Figure –1). However, in terms of thermal comfort especially during winter the heating requirement of the building will increase with the ventilation rate. This demand varies with time, wind characteristics of the place, opening and closing of windows and doors by its occupants and the thermal state of the building. In summer, cooling is ideal for both the building and its occupants to prevent internal heat gains. By directing the high velocity wind around the human body the evaporative rate at the skins surface can be increased thereby achieving a cooling sensation. The recommended upper limit of indoor air movement is 0.8 m/sec, which permits the inhabitants to occupy a space about 2 °C warmer and 60% relative humidity with optimum comfort. The traditional way to cool buildings is to provide large openings along the exterior wall with the principle that higher the ventilation rate greater the loss of heat to the external environment. But such an arrangement would work only when the outdoor te mperature is in the range of comfort zone. When controlled indoor environments are desired especially during the occupancy period’s night ventilation is recommended. In this technique the building is cooled at night so that it can absorb the heat generated during the day (Allard F, 1998). Based on wind tunnel experimental observations, the factors that affect the indoor airflow are: Orientation: External features: Cross-ventilation: Position of openings: Size of openings: Control of openings: Literature review The following are studies that have been made of different aspects of wind using Computational Fluid dynamics. CFD evaluation of wind speed conditions in passages between parallel buildings: This analysis undertaken by Blocken B et al (2007) mainly focuses on the wind speed conditions in passages between parallel buildings in combination with the accuracy of the commercial CFD code Fluent 6.1.22 when the wall-function roughness modifications are applied to them. The Venturi effect is also studied to determine the amount of increase in wind speed in the passage due to the decrease in flow section. The results obtained were compared with various previously proven experiments carried out by experts in the field. As the title indicated the case undertaken involves a pair of rectangular buildings measuring 40m x 20m x 20m, placed adjacent to each other and separated by a narrow passage. The width of the passage is widened (for example, 2, 4, 6, 8, 10, 15, 20, 30, 40, 60, 80, 100 m) with every case to clearly understand the Venturi effect. The dimension of the computational domain is 20.5x14x18m3; the whole setup is placed at a distance of 5m from the inlet and simulated with a wind speed of 6.8m/sec based on initial results. The results recorded at the end of the simulation process are discussed as follows. They are based on the amplification factor, which is defined as the ratio of the mean wind speed at a certain location to the mean wind speed at the same location without the buildings present. As such it is a direct indication of the effect of the buildings on the wind speed (Blocken B et al, 2007). Pedestrian level wind profile: In context to this research, for narrow passages (example w=2m) this amplification factor occurs maximum at the centerline immediately behind the entrance. When the distance between the buildings are slightly increased (example w=10m), the flow streams deflecting off the inner edges of the buildings combine into a large jet stream and records an increase in the amplification factor. However this property is lost when the width of the passage is of a high order (example w=30m). Overall wind profile: To understand the overall wind profile, six vertical lines were identified along the passage’s center plane for the case of w=6m. The lines depicted the fact that there was an increase in the wind speed at the ground level due to the downdraft of the wind along the front faà §ade of the building and a decrease in wind speed at the end of the passage due to the exit of flow from the passage. Also for these cases, there was no significant increase in the wind speed with the increase in height. Flow rates at different points in the passage: To evaluate the Venturi-effect three fluxes were defined, one along the vertical plane, another along the horizontal plan and the final being similar to the former one but in the absence of the buildings. When the flow rate was calculated for narrow passages, it stated an increase in wind speed by only 8% due to the Venturi effect. However for larger widths the flow rate was lower than the free-field flux. This shows that the wind has a tendency to flow over and around the building rather than be forced through the passage as previously believed. Thus there is a lack of strong Venturi effect and the flow in the passage can be attributed as the channeling effect for these cases. The research also concluded that there were discrepancies in the CFD results due to the use of the roughness factor and advised future users to simulate an empty field before positioning the buildings to clearly identify the difference in results. Further research into the Venturi effect was also implied. Computational analysis of wind driven natural ventilation in buildings: Evola G and Popov V (2006) research focuses on the application of three-dimensional Reynolds Averaged Navier-Strokes (RANS) modeling on wind driven natural ventilation with specific detail to the pressure distribution and flow pattern within the building. The various cases would be simulated with the standard k-e model and the Renormalization Group theory (RNG). Within the framework of natural ventilation both single sided ventilation and cross ventilation would be studied and the results obtained using CFD will be compared with LES models and empirical methods for its reliability.  Ã‚  Ã‚   The building undertaken consists of a 250mm x 250mm x 250mm cube punctured with a centrally located 84mm x 125 mm opening on the wind ward side (Case 1). In Case 2 the door like opening is placed on the leeward side and in Case 3 both the openings are retained to test the cross ventilation principle. On comparison between the CFD results obtained for Case 1 and 2, Case 2 portrays a better flow pattern especially at the mouth of the opening. This leads to a better ventilation rate than Case 1 though in contrast to the theoretical data that good ventilation rate and flow patterns are achievable only when the opening faces the incoming winds. To establish the phenomenon further experimentation into the field was suggested. Between Cases 1, 2 and 3, cross ventilation clearly stands out as the best option of them all, both in terms of velocity and distribution. Also the study concluded that the measured RNG results matched approximately to the theoretical results of Cases 1 and 2. But a significant amount of deviation was observed in Case 3. The RNG model was only slightly intense than the k-e model generally used. The research also concluded that there were discrepancies in the CFD results due to the use of the roughness factor and advised future users to simulate an empty field before positioning the buildings to clearly identify the difference in results. Further research into the Venturi effect was also implied. CFD modeling of unsteady cross-ventilation flows using LES: This research undertaken by Cheng-Hu Hu et al (2008) employs the LES method to investigate the fluctuating ventilation flow rate induced by the wind for a cross-ventilated building. The results from CFD were compared with those previously acquired from wind tunnel tests.   Ã‚   The building proposed for the study consists of a rectangular box with two openings of equal size located opposite to each other. The wind is simulated from 0 °(Case 1) and 90 °(Case 2) to the building at a rate of 1m/sec, to study the flow pattern in and around it. When the air approaches the building the ventilation rate is unsteady at the mouth of the openings due to turbulence and in the flow separation layer due to shear. In Case 1 the wind is accelerated through the opening and directed downwards inside the building. This phenomenon brings about a circulation of the internal air before guiding the wind upwards and out through the window on the leeward side of the building. The air exchange occurs due to the mean flows through the opening. In Case 2 where the wind is parallel to the windows, the air moves in and exits rapidly causing fluctuating flows thereby leading to air exchange. In this case turbulence prone areas are formed at the rear of the building. When these results were compared with the wind tunnel data, Case 1 portrayed similarities while Case 2 had major deviations. Further study was proposed for understanding the reason behind such deviations. Case studies The Bahrain world trade centre was the world’s first building to ‘aesthetically incorporate commercial wind turbines into the fabric of the building’ [ ]. The complex consists of a three-storied sculpted podium and basement from where the 240m high towers rise up into the sky. The two towers comprise of 51 floors each and are connected by means of three, 31.5m span bridges at 60m, 96m and 132m levels [ ]. They are oval in section for aerodynamic reasons and follow a shallow V-shape in plan for adequate blade clearance. Sitting on each of this 70 ton spandrel is an 11-ton nacelle to which the industry approved horizontal axis wind turbines are fixed by special means. The turbine has a rotor diameter of 29m and is stall controlled with centrifugally activated feathering tips for air brakes (Killa S Smith Richard F, 2008). The turbines are oriented facing the Arabian Gulf intercepting the path of the dominant winds. The decision to harness the prevailing wind was thought of from the initial stage drawing inspiration from ‘the regional wind towers and the vast sails of the traditional Arabian Dhow which utilise the wind to drive them forward’. Numerous Computational fluid dynamics models and wind tunnel tests were carried out to determine the final building form. The result was a skyward tapering, elliptical structure, carved out by the wind that functions as aerofoil sections (Wood A, 2008). The shape and spatial relationship of the towers aid in adhering the wind in a â€Å"S’ flow whereby the center of the wind stream remains nearly perpendicular to the turbine within a 45 ° wind azimuth, either side of the central axis (Killa S Smith Richard F, 2008). This increases the turbine efficiency, number of working hours and minimizes the stress on the blade caused by yawing [ ]. Furthermore, the two towers were placed such that they create a ‘V’ shaped space in between them, as well as a negative pressure behind the blocks, thus creating an opportunity for the Venturi effect to accelerate wind velocity onto the turbines (Binder G, 2006) by as much as 30% more than the source wind (Killa S Smith Richard F, 2008). The tapering profile combined with the increased onshore wind velocity at higher altitudes creates a near equal regime of wind speed on each of the three turbines, irrespective of its location, allowing them to rotate at the same speed and generate approximately the same amount of energy (Wood A, 2008). Table 1: Annual energy output Utilisation of Wind Energy for High Rise Building Power Utilisation of Wind Energy for High Rise Building Power Introduction The price of conventional energy is on the rise, due to the ever-widening gap between demands and supply.

However, the breakthrough occurred when Charles.F.Brush erected the first automatically operating wind turbine at Ohio in 1888 [ ]. It was fabricated using wood and had a rotor diameter of 17m with 144 blades. The system recorded very low efficiency and was mainly used to charge batteries. The reason behind the poor efficiency was due to the large number of blades, which was later discovered by Poul la Cour who introduced fewer blades into his wind turbine. Though such developments were achieved at an early stage in innovation, it was not until 1980 that the prominent application of renewable energies was sought after (Boyle G, 2004). Wind energy is the harnessing of the kinetic energy prevalent in moving air masses. This kinetic energy for any particular mass of moving air (Boyle G, 2004) is given by the formula: K.E = 0.5mV ² where, m – mass of the air (kg) and V – wind velocity (m/s). However this mass of moving air per second is: m = air density x volume of air flowing per second m = air density x area x velocity   Thus, m = rAV where, r – density of air at sea level = 1.2256 kg/m ³ and A – area covered by the flowing air (m ²) Substituting this value of m in the former equation, K.E. = 0.5rAV ³ (J/s) But energy per unit of time is power and hence the above equation is the power available from the wind. It is also evident that the power is directly proportional to thrice the wind velocity. In other words even a marginal increase in wind speed would yield three folds of the nominal power. This is the critical fact based on which the whole energy process is evolved. However not all of this power can be exhausted since it would lead to nil outflow through the wind turbine, that is no flow of air behind the rotor. This would lead to no flow of air over the turbine causing total failure of the system. According to Albert Betz the maximum amount of power that can be harnessed from the wind is 59.3%. This is often referred to as the Betz limit and has been proven by modern experiments. Some of the advantages of wind energy include: It is based on a non-exhaustive resource and hence can be harnessed for generations. It is a clean and eco friendly way of producing energy. In its working lifetime, the wind turbine produces eighty times the amount of energy that goes into its manufacturing and thus has diminishable net impact on the environment. It does not require any additional resources such as water supply unlike conventional power generation. It can boost the economy of the region (wind farms). Wind turbines: Wind turbines are the modern day adaptations of the yesteryear windmills but unlike their counterparts they are mainly used for power generation. These new age systems come in different shapes and have various configurations, the well established of them all are the Horizontal axis wind turbine and the Vertical axis wind turbine. Write a brief about horizontal wind turbines and vertical wind turbines. BUilding integrated Wind Turbines (BUWT): Building integrated wind turbines are associated with buildings designed and shaped with wind energy in mind (Stankovic S et al, 2009). They are relatively a new way of harnessing energy that is gaining popularity at a quick pace. Small scale wind turbines on house roofs and retrofitting also fall under this category. The design of BUWTs is a complicated affair and involves the careful consideration of various factors. Since turbines are fixed into the building’s fabric its impact on the environment, building’s response and needs of its owners and occupants need to be weighed equally. Also numerous design decisions such as planning, structure, services, construction and maintenance depend on this single process (Stankovic S et al, 2009). With the increase in the scale of the proposal the importance of these factors increases simultaneously. The proposal generally spans from the number, scale, type and location of the turbines together with its annual energy yield and design life. A good BUWT based building should be a wholesome design that does not prejudice the buildings efficient functioning for energy generation. Generic options for BUWTs: Stankovic S et al (2009) explains that the wind turbines can be fixed on to a building in enumerable ways. Each method can accomplish a different level of power depending on the type of turbine used and the form of the building it is mounted upon. On top of a square/ rectangular building: This configuration is on the principle that the wind velocity increases with height and hence the amount of energy generated would be of a higher order (10% increase with wind acceleration). An added advantage is that the turbine would experience relatively little turbulence. But access to the turbine for maintenance and decommissioning works may be difficult. If mounted on tall buildings the turbines may threaten the visual quality of the skyline. On top of a rounded building: This case is very similar to the previous configuration except that with the use of rounded faà §ade the mean tower height can be considerably diminished. Also the rounded profile influences the local acceleration (15% increase in energy). The low tower height favors easy access to the turbine but leads to blade flicker and noise issues. Concentrator on top of a rounded building: This case is well suited to areas with bi-directional winds (20% energy increase over a free standing equivalent due to local acceleration). Vertical axis wind turbines are better suited for this feature while Horizontal axis wind turbines need to be suitably altered to achieve the same status. The building spaces that act as concentrators may be inhabited with suitable acoustical treatment. This case also encounters the same drawbacks as listed in the previous case. Square concentrator within a building faà §ade: As before, this configuration takes advantage of the higher quality winds at higher altitudes and local acceleration thereby achieving 25% increase in energy and 40% increase for bi-directional winds. This option is best suited for buildings with narrower profiles. There may be a loss in the saleable area of the building but the aperture can be converted into an exclusive feature such as a sky garden. The opening also relieves the wind loading on the building’s facade leading to simpler structural solutions. Vertical axis wind turbine is the only choice for integration due to its square swept area. Circular concentrator within a building faà §ade: This is very similar to the square concentrator except the opening is accustomed to hold pitch controlled horizontal axis wind turbines with fixed yaw. Also, a 35% increase for uniform wind and 50% increase in energy for bi-directional winds are achievable in this method. But on the down side, this technique is more expensive due to the cylindrical shroud. On the side of a building: In this technique, an increase in 80-90% in energy than the freestanding equivalents is achievable only if the building form is optimized to the local wind character. Only reliable vertical axis wind turbines can be used for power generation due to access issues. For higher swept area, more number of turbines should be used. Between multiple building forms: This type of an option opens out many doors for a range of architectural forms. Unlike the previous cases, the buildings orientation, form, shape and spacing play key roles in the performance of the turbines. Vertical axis wind turbines are better suited for this purpose. Guidelines for BUWT’s: The following are some guidelines outlined by Stankovic S et al (2009) for incorporating wind turbines into a structure: BUWTs should be tailored to the specific site for good results. Adequate wind resources should be available on site. If however if the site is under resourced steps are to be adopted to deliberately elevate the quality of the wind through the buildings form or turbine. The impact of its surroundings should also be considered before commissioning such a project. The dominating wind direction and its intensity should be observed from meteorological data. This would help in determining the form and orientation of the building together with finalizing the position of the wind turbine to make the most out of the available resource. Environmental impact assessment corresponding to the site should be carried out to foresee the adverse effects the turbines may create. Acoustic isolation may be sought for in some areas within the building if it lies at close proximity to the rotor. Natural ventilation and day lighting qualities of the building may be challenged and forced to settle for artificial means. The type and position of openings, external shading devices, smoke extracts etc should be handled with appropriate care to avoid draught winds. Access to the wind turbines for maintenance and decommissioning must be provided suitably. The aesthetic quality of the mounted turbines must harmonize with its surroundings and should not over power the pedestrians at ground level. To this end well suited screening devices such as canopies, screens and landscape may be utilized as per the necessity. The overall success of BUWT project depends on its ability to deliver the expected power. Inability to comply with this effect would result in the failure of its intended purpose from both an environmental and design point of view. Thus the electricity demand of the building and the level to which this would be met with should be estimated prior to turbine design to secure maximum benefits. Wind flow prediction and energy yields: For any project to be successful, Wind flow and building design (Taranath Bungale S, 2005) When the air moves in a vertical direction it is referred to as a current. These currents play a major role in meteorology whereas the gradual decrease in wind speed and high turbulence of the horizontal motion of air, at the ground level, are vital in building engineering. In urban areas, this zone of turbulence extends to a height of approximately one quarter of a mile aboveground and is called the surface boundary layer. Above this layer, the horizontal airflow is no longer influenced by the ground effect. The wind speed at this height is known as the gradient wind speed, and it is precisely in this boundary layer where most human activity is conducted. Characteristics of wind: The flow of wind is complex because many flow situations arise from the interaction of wind with structures. A few characteristics of wind include: Variation of wind velocity with height: The viscosity of air reduces its velocity adjacent to the earth’s surface to almost zero. A retarding effect occurs in the wind layers near the ground, and these layers in turn successively slow the outer layers. The slowing down is reduced at each layer as the height increases, and eventually becomes negligibly small. The height at which velocity ceases to increase is called the gradient height, and the corresponding velocity, the gradient velocity. At heights of approximately 366m aboveground, the wind speed is virtually unaffected by surface friction, and its movement is solely dependant on prevailing seasonal and local wind effects the height through which the wind speed is affected by topography is called the atmospheric boundary layer. Wind turbulence: Motion of wind is turbulent and it occurs in wind flow because air has a very low viscosity-about one-sixteenth that of water. Any movement of air at speeds greater than 0.9 to 1.3 m/s is turbulent, causing air particles to move randomly in all directions. Vortex shedding: In general, wind buffering against a bluff body such as a rectangular building gets diverted in three mutually perpendicular directions. However, only the longitudinal winds and the transverse winds or crosswinds are considered in civil engineering. When a free flowing mass of air encounters a building along its path, the originally parallel upwind streamlines are displaced on either side of the building. This results in spiral vortices being shed periodically from the sides into the downstream flow of the wind, called the wake. At relatively low wind speeds the vortices are shed, that is, break away from the surface of the building and an impulse is applied in the transverse direction. Distribution of pressures and suctions: When air flows around the edges of a structure, the resulting pressures at the corners are much in excess of the pressures on the center of elevation. This has been evident by the damages caused to corner windows, eave and ridge tiles, etc in windstorms. Wind tunnel studies conducted on scale models of buildings indicate that three distinct pressure areas develop around the building. They are: Positive pressure zone on the upstream face (Region 1) Negative pressure zone at the upstream corners (Region 2) Negative pressure zone on the downstream face (Region 3) The highest negative pressures are created in the upstream corners designated as Region 2. Wind pressures on a buildings surface are not constant, but fluctuate continuously. The positive pressure on the upstream or the windward face fluctuates more than the negative pressure on the downstream or the leeward face. The negative pressure region remains relatively steady as compared to the positive pressure zone. The fluctuation of pressure is random and varies from point to point on the building surface. Nearby buildings can have a significant influence on wind forces. If they are the same height as the structure being considered then they will mostly provide shelter, although local wind loads can be increased in some situations. Where surrounding buildings are significantly taller they will often generate increased wind loading (negative shelter) on nearby lower structures. Shelter can result from either from the general built-environment upwind of the site or from the direct shielding from specific individual upwind buildings (Blackmore P, 2004). Natural ventilation The three natural ventilation airflow paths in buildings are (Pennycook, 2009): Cross ventilation Single-sided ventilation Passive stack ventilation Advantages of cross ventilation: Greater rates of ventilation can be achieved under amicable weather conditions. Can be utilized for deep-plan spaces with operable windows on the external wall. Incumbents have control over ventilation. Relatively cost free. Can be incorporated with thermal masses. However, it has certain limitations such as: Internal space layout must be hindrance free for easy, clear flow of air. Internal partitions must be within 1.2m height and tall cupboards must be placed alongside the windows. Natural ventilation can occur only under the presence of suitable winds. Poor planning and positioning of windows may cause disruptive draughts and gusts. Winter ventilation is problematic. Unsuitable for buildings located in noisy and pollution prone environments. The requirements of fresh air supply are governed by the type of occupancy, number and activity of the occupants and by the nature of any processes carried out in the space (Koenigsberger et al, 2001). When natural ventilation is stipulated for good indoor air quality, the amount and nature of the dominant pollutant source in the space should be identified. Based on this data the ventilation rate for the space can be calculated such that the pollution level does not cross a preset specific mark. Generally the concentration of the pollutants decreases with the increase in airflow rate (Figure –1). However, in terms of thermal comfort especially during winter the heating requirement of the building will increase with the ventilation rate. This demand varies with time, wind characteristics of the place, opening and closing of windows and doors by its occupants and the thermal state of the building. In summer, cooling is ideal for both the building and its occupants to prevent internal heat gains. By directing the high velocity wind around the human body the evaporative rate at the skins surface can be increased thereby achieving a cooling sensation. The recommended upper limit of indoor air movement is 0.8 m/sec, which permits the inhabitants to occupy a space about 2 °C warmer and 60% relative humidity with optimum comfort. The traditional way to cool buildings is to provide large openings along the exterior wall with the principle that higher the ventilation rate greater the loss of heat to the external environment. But such an arrangement would work only when the outdoor te mperature is in the range of comfort zone. When controlled indoor environments are desired especially during the occupancy period’s night ventilation is recommended. In this technique the building is cooled at night so that it can absorb the heat generated during the day (Allard F, 1998). Based on wind tunnel experimental observations, the factors that affect the indoor airflow are: Orientation: External features: Cross-ventilation: Position of openings: Size of openings: Control of openings: Literature review The following are studies that have been made of different aspects of wind using Computational Fluid dynamics. CFD evaluation of wind speed conditions in passages between parallel buildings: This analysis undertaken by Blocken B et al (2007) mainly focuses on the wind speed conditions in passages between parallel buildings in combination with the accuracy of the commercial CFD code Fluent 6.1.22 when the wall-function roughness modifications are applied to them. The Venturi effect is also studied to determine the amount of increase in wind speed in the passage due to the decrease in flow section. The results obtained were compared with various previously proven experiments carried out by experts in the field. As the title indicated the case undertaken involves a pair of rectangular buildings measuring 40m x 20m x 20m, placed adjacent to each other and separated by a narrow passage. The width of the passage is widened (for example, 2, 4, 6, 8, 10, 15, 20, 30, 40, 60, 80, 100 m) with every case to clearly understand the Venturi effect. The dimension of the computational domain is 20.5x14x18m3; the whole setup is placed at a distance of 5m from the inlet and simulated with a wind speed of 6.8m/sec based on initial results. The results recorded at the end of the simulation process are discussed as follows. They are based on the amplification factor, which is defined as the ratio of the mean wind speed at a certain location to the mean wind speed at the same location without the buildings present. As such it is a direct indication of the effect of the buildings on the wind speed (Blocken B et al, 2007). Pedestrian level wind profile: In context to this research, for narrow passages (example w=2m) this amplification factor occurs maximum at the centerline immediately behind the entrance. When the distance between the buildings are slightly increased (example w=10m), the flow streams deflecting off the inner edges of the buildings combine into a large jet stream and records an increase in the amplification factor. However this property is lost when the width of the passage is of a high order (example w=30m). Overall wind profile: To understand the overall wind profile, six vertical lines were identified along the passage’s center plane for the case of w=6m. The lines depicted the fact that there was an increase in the wind speed at the ground level due to the downdraft of the wind along the front faà §ade of the building and a decrease in wind speed at the end of the passage due to the exit of flow from the passage. Also for these cases, there was no significant increase in the wind speed with the increase in height. Flow rates at different points in the passage: To evaluate the Venturi-effect three fluxes were defined, one along the vertical plane, another along the horizontal plan and the final being similar to the former one but in the absence of the buildings. When the flow rate was calculated for narrow passages, it stated an increase in wind speed by only 8% due to the Venturi effect. However for larger widths the flow rate was lower than the free-field flux. This shows that the wind has a tendency to flow over and around the building rather than be forced through the passage as previously believed. Thus there is a lack of strong Venturi effect and the flow in the passage can be attributed as the channeling effect for these cases. The research also concluded that there were discrepancies in the CFD results due to the use of the roughness factor and advised future users to simulate an empty field before positioning the buildings to clearly identify the difference in results. Further research into the Venturi effect was also implied. Computational analysis of wind driven natural ventilation in buildings: Evola G and Popov V (2006) research focuses on the application of three-dimensional Reynolds Averaged Navier-Strokes (RANS) modeling on wind driven natural ventilation with specific detail to the pressure distribution and flow pattern within the building. The various cases would be simulated with the standard k-e model and the Renormalization Group theory (RNG). Within the framework of natural ventilation both single sided ventilation and cross ventilation would be studied and the results obtained using CFD will be compared with LES models and empirical methods for its reliability.  Ã‚  Ã‚   The building undertaken consists of a 250mm x 250mm x 250mm cube punctured with a centrally located 84mm x 125 mm opening on the wind ward side (Case 1). In Case 2 the door like opening is placed on the leeward side and in Case 3 both the openings are retained to test the cross ventilation principle. On comparison between the CFD results obtained for Case 1 and 2, Case 2 portrays a better flow pattern especially at the mouth of the opening. This leads to a better ventilation rate than Case 1 though in contrast to the theoretical data that good ventilation rate and flow patterns are achievable only when the opening faces the incoming winds. To establish the phenomenon further experimentation into the field was suggested. Between Cases 1, 2 and 3, cross ventilation clearly stands out as the best option of them all, both in terms of velocity and distribution. Also the study concluded that the measured RNG results matched approximately to the theoretical results of Cases 1 and 2. But a significant amount of deviation was observed in Case 3. The RNG model was only slightly intense than the k-e model generally used. The research also concluded that there were discrepancies in the CFD results due to the use of the roughness factor and advised future users to simulate an empty field before positioning the buildings to clearly identify the difference in results. Further research into the Venturi effect was also implied. CFD modeling of unsteady cross-ventilation flows using LES: This research undertaken by Cheng-Hu Hu et al (2008) employs the LES method to investigate the fluctuating ventilation flow rate induced by the wind for a cross-ventilated building. The results from CFD were compared with those previously acquired from wind tunnel tests.   Ã‚   The building proposed for the study consists of a rectangular box with two openings of equal size located opposite to each other. The wind is simulated from 0 °(Case 1) and 90 °(Case 2) to the building at a rate of 1m/sec, to study the flow pattern in and around it. When the air approaches the building the ventilation rate is unsteady at the mouth of the openings due to turbulence and in the flow separation layer due to shear. In Case 1 the wind is accelerated through the opening and directed downwards inside the building. This phenomenon brings about a circulation of the internal air before guiding the wind upwards and out through the window on the leeward side of the building. The air exchange occurs due to the mean flows through the opening. In Case 2 where the wind is parallel to the windows, the air moves in and exits rapidly causing fluctuating flows thereby leading to air exchange. In this case turbulence prone areas are formed at the rear of the building. When these results were compared with the wind tunnel data, Case 1 portrayed similarities while Case 2 had major deviations. Further study was proposed for understanding the reason behind such deviations. Case studies The Bahrain world trade centre was the world’s first building to ‘aesthetically incorporate commercial wind turbines into the fabric of the building’ [ ]. The complex consists of a three-storied sculpted podium and basement from where the 240m high towers rise up into the sky. The two towers comprise of 51 floors each and are connected by means of three, 31.5m span bridges at 60m, 96m and 132m levels [ ]. They are oval in section for aerodynamic reasons and follow a shallow V-shape in plan for adequate blade clearance. Sitting on each of this 70 ton spandrel is an 11-ton nacelle to which the industry approved horizontal axis wind turbines are fixed by special means. The turbine has a rotor diameter of 29m and is stall controlled with centrifugally activated feathering tips for air brakes (Killa S Smith Richard F, 2008). The turbines are oriented facing the Arabian Gulf intercepting the path of the dominant winds. The decision to harness the prevailing wind was thought of from the initial stage drawing inspiration from ‘the regional wind towers and the vast sails of the traditional Arabian Dhow which utilise the wind to drive them forward’. Numerous Computational fluid dynamics models and wind tunnel tests were carried out to determine the final building form. The result was a skyward tapering, elliptical structure, carved out by the wind that functions as aerofoil sections (Wood A, 2008). The shape and spatial relationship of the towers aid in adhering the wind in a â€Å"S’ flow whereby the center of the wind stream remains nearly perpendicular to the turbine within a 45 ° wind azimuth, either side of the central axis (Killa S Smith Richard F, 2008). This increases the turbine efficiency, number of working hours and minimizes the stress on the blade caused by yawing [ ]. Furthermore, the two towers were placed such that they create a ‘V’ shaped space in between them, as well as a negative pressure behind the blocks, thus creating an opportunity for the Venturi effect to accelerate wind velocity onto the turbines (Binder G, 2006) by as much as 30% more than the source wind (Killa S Smith Richard F, 2008). The tapering profile combined with the increased onshore wind velocity at higher altitudes creates a near equal regime of wind speed on each of the three turbines, irrespective of its location, allowing them to rotate at the same speed and generate approximately the same amount of energy (Wood A, 2008).
