Ken Yeang (born 1948) is a Malaysian architect, ecologist and author known for his signature eco-architecture and eco-masterplans. Yeang is an early pioneer of ecology-based green design and master planning, carrying out design and research in this field since 1971.Ken Yeang’s ideas and architecture have been creatively published worldwide. This book, however, marks the first definitive overview of Yeang’s work. As well as an extensive introduction by author Sara Hart, it includes a preface by Lord Foster and a further article by leading architect and academic John Frazer and commentary by Leon van Schaik. The book is organized thematically by project. It features over 30 projects by Ken Yeang drawn from over three decades of practiceEditorial Reviews About the Author,• Sara Hart received a Master of Architecture degree from Columbia University in New York City. After many years, she turned to design journalism, specializing in building technology and innovation. She has written extensively about new materials, technologies and sustainable practices. • David Littlefield is a senior lecturer at the University of the West of England. He has written and edited a number of books. Sara Hart in her review specially mentioned that Ken Yeang is the person who Rethink about skyscrapers and gave a definitely different to it. Putting aside the conflation of “bad” with “ugly,” there often is a causal link between a building’s look and its sustainable credentials, if for no other reason than green architecture demands a certain set of materials, economy and form. Now, this form-function relationship need not mean ugly, but Ken Yeang faced it, sometimes it really does.It’s worth remembering that a lot of architecture in general is ugly. And for that matter, a lot of green architecture isn’t always very green. But Ken Yeang tried to change this fact in a different way. What Sara Hart wants is to spread Ken Yeang’s innovative ideas among the world. Ken Yeang is internationally recognized as the leading supporter of ecological design in architecture. He has built over 200 buildings globally applicable, and also published number of books. He is the best inventor of the green skyscraper; it was his original idea to incorporate bioclimatic features in a high-rise building type. The Malaysian architect’s visionary approach to green building bucks the mainstream, embracing the tall building as an urban fact, a problem to be solved afresh with each new design. He seeks what he calls ecomimesis in buildings, a way to copy and paste nature into our high-rise designs. But just as importantly ,the building must look extremely good too — and definitely different.”Good architecture is green architecture but green architecture isn’t necessarily good architecture” In other words a good building should be sustainable already, environmentally concern should be taken in, Ken Yeang responded to that. He also explains that the reason why solar architecture in the 1970’s failed was because they looked like built plumbing and are ugly. If anybody wants eco-structure to be acceptable to the public they have to be aesthetically beautiful. He also explains that a green building should look like a modernist building, it should be something new. And a building that acknowledges nature in form might help sharpen awareness about the role that architecture plays in our often un-green urban spaces. Though he has authored many books about his work and his ideas, this is the first descriptive book to cover his forty-year career, by adding all the research he has done. Yeang’s most momentous projects, Eco-Architecture begins with his earliest work on environmental design, executed as a student at the Architectural Association and then a PHD student at Cambridge in the early 1970s, and with his most recent projects with Llewelyn Davies Yeang in London and then in Kuala Lumpur. With an introduction by Lord Norman Foster, this book on the 40 year career of eco-architect KenYeang is presenting an architectural alternative to the business-as-usual ecological occupation of current development. Author Sara Hart has here assembled a collection of explanation combined with page after page of large colour renderings of Yeang’s most provocative buildings—each go along with by diagrams and sections—to illustrate each building’s unique set of environmental controls. She further points out that in 2008 ‘The Guardian’ named Yeang as one of fifty people in the world that could help save the planet.This is the first time such an extensive monograph has been assembled, one in which Yeang’s work can be understood at the many different scales he works in. As such, the book is divided into six chapters:• Bioclimatic Design,• EcoMasterplanning, • Transitional Projects, • Vertical Urbanism,• Technical Innovation, and • Vertical EcoInfrastructure. Each chapter carries three of his projects as examples, as well as with his most eye-catching eco-towers, including the Spire Edge, which is an eco office complex across 1.6 mn sq.ft. Based on a philosophy and a process called ‘Mainstream Green’, it is upto 30% more energy efficient than its peers. And the L Tower, which is a condominium development under construction in Toronto, Canada. Designed by Architect Daniel Libskind. Yet, it is in the books final six pages, written by Yeang himself, in which the book’s philosopher’s words revealed. Breaking our environment into four strands of ‘Eco-Infrastructure’—represented within by the colour green (nature), grey (roads, sewers, etc.), blue (water), and red (buildings)—Yeang ultimately presents the notion of our built systems will work most effectively if they can be allowed to imitate the ecological properties and attributes of Nature. “Technology should not be held as the only way for society to advance. Here, Urban Green looks at other options. Neil Chambers provides a plan for action that goes beyond simply reducing our human activities and built environment’s impact on nature. It indicates how nature could thrive in synchrony with society. It relooks at green building and speculates how civilization might extend into the future as the next generation of sustainability.”Ken Yeang- innovator and leader in Green design.Ken Yeang has made Green design the driving focus of his life’s work. Yeang discussed the evolution of his practice of green design through a chronology of past projects. ‘Experiments’ is the key way Yeang discussed his approach to design. The seamless integration of Humans, Nature and the Build Environments as a whole was his aim and definition of ‘Green Design’.His designs allow sun and wind to flow through a building, embracing the natural climate as an advantage rather than sealing it out as an enemy. He develops this open dynamic of permeable boundaries with many transitional areas — such as recessed balconies, large skycourts, and open-air atriums with louvered coverings — further blurring the distinction between inside & outside space. Living vegetation often encourage his structures in a system of hanging, vertical, or spiraling gardens used for shading and filtering.The principle of “bioclimatic architecture,” or using external conditions for internal climate control, informs all of Yeang’s work; his buildings contribute to their own environment, producing energy rather than simply consuming it. The benefits are economical, ecological, and psychological: not only do Yeang’s buildings save money on heating and air conditioning, but they support sustainable development and the emotional well-being of those who live and work in them. Yeang’s Editt Tower in Singapore (under construction since 1998, completion pending) creates vertical continuity with connected ramps that allow pedestrians to ascend the tower along a climbing internal “street” lined with sky gardens, terraces, exhibition and performance spaces, cafes, shops, and offices. An integrated arrangement for sun shades, window glazing, light shelves, rainwater catchment scallops, and photovoltaic panels combine to reduce solar load on the windows, collect water, bounce light onto the ceilings and back into the building, and reduce overall energy demand and cooling load.Yeang’s projects are experiments thereby making the design framework of his projects his method. Starting with climate,( explained above ) Yeang clarified the methodical and scientific way he designs to ensure that being green was not a superficial tack on. Yeang’s design was thoroughly investigated to produce the statistical data counting the potential of green design, both environmentally and financially. Part of the success of Yeang’s experimental practice is the analysis of results and outcomes. He examined the success and failures and strived for better. ‘Some ideas take a long time to implement’ he mentioned. Yeang discussed green design like an encouraging teacher, providing information, examples, and leadership but most importantly encouragement. ‘Try to exceed bench marks’, ‘ Think green from day one’, Yeang’s talk was sprayed with optimism and hope for the future of green design. Ken Yeang is confident that architects can do more than just ‘put veggies in the building’. Ken Yeang pointed out that the trouble with buildings today is that they are not ecologically designed. 80% of all the environmental impacts of buildings are designed into the buildings before they have been built. According to Ken Yeang the ideal green building is one which is ecomimetic and which integrates seamlessly and benignly with the natural environment at 3 levels: physically, systemically and temporally.Critisism:Ken Yeang pointed out that , Eco-design applies not just to how we design, construct, use, recycle, and eventually create our buildings back into the environment. Eco-design concerns not just those in the design community but all whose roles in the global economy impact on the environment , simply stated, if we are able to give attention to all that we make and all that we do with the natural environment in a unspoiled and gentle way, then there will be no environmental problems at all.
