His architect and planning firm, T. R. Hamzah and Yeang ( www. trhamzahyeang. com ) has sister offices in the UK as Llewelyn Davies Yeang ( www. ldavies. com ) and in China as North Hamzah Yeang Architectural and Engineering Company ( Beijing ), a joint venture with Norinco ( a Chinese Army's company ) with branch offices in Shenzen, Shanghai, Guangzhou and Chongqing.

Yeang has designed buildings and ecocity masterplans worldwide including New York, London, Singapore, Hong Kong, Kuwait, Canada, China, Turkey, Kazakhstan, Uzbekistan, Saudi Arabia, United Arab Emirates, Taiwan, UK, Malaysia and China.

Yeang's work on the theory of ecodesign and its advancement is where Yeang has significantly contributed and advanced this field of endeavor.

Yeang has lectured extensively in over 30 countries at conferences and schools of architecture to proselytise his ideas.

Ken Yeang has created outstanding designs throughout his 40 plus years professional career and continues to develop his original and fresh approach to the forms and systems of his buildings while pursuing theoretical and technical advancements and the ecological architectural style for ecodesign – as a new “ green ” aesthetic.

Lord Norman Foster of Thames Bank states, '.. Ken Yeang has developed a distinctive architectural vocabulary that extends beyond questions of style to confront issues of sustainability and how we can build in harmony of the natural world ..' ( 2011 ).

Yeang has completed over 200 projects since 1975.

Born in 1948 in Penang, Malaysia, Yeang attended Penang Free School and Cheltenham Boys College ( a British ' public school ' in Gloucestershire, UK ), obtained his first qualifications in architecture from the Architectural Association School ( London ), and received a PhD in ecological design and planning from Cambridge University's Department of Architecture for his dissertation, " A Theoretical Framework for Incorporating Ecological Considerations in the Design and Planning of the Built Environment ", published as Designing with Nature ( McGraw-Hill, 1995 ) that became the springboard for his pioneering work in ecodesign, green architecture and ecocity masterplanning.

His innovative ecodesign work led his firm, T. R. Hamzah and Yeang to be cited in the US magazine, Fast Company ( March 2011 ) as among the top 8 most innovative architect firms in the world.

Yeang continued to extend these early bioclimatic passive-mode design ideas to other low and medium-rise building types, which he now further incorporates confidently ecodesign strategies from his earlier Cambridge doctorate research, applied to a variety of building types in other climatic zones such as in cold and temperate climates with variable seasonal changes.

Continuing to carry out a research programme on ecodesign in-house within his professional practice and undertaken over several decades, Yeang uniquely applies his research outcomes concurrently in his built work.

Yeang ’ s single minded pursuit of ecodesign and ecomasterplanning and their aesthetics for close to four decades have influenced countless architects and professionals whose work impinges on the environment not just in the way they approach design, planning and the natural environment but aesthetically ( greatly encouraged by his former PhD Supervisor at Cambridge University, Professor John Frazer ) – in asking what a green building and masterplan should look like?

What is particularly motivating in Yeang's work is this original eco aesthetic, as an aspect of ecodesign that is close to Yeang ’ s heart.

Because ecodesign in the 1970s did not have the benefit of prior research or theoretical models and frameworks, Yeang early years involved doing empirical research, experimental design, and investigative studies of ecological processes that he could replicate or mimic in his humanmade structures.

In addition to Aalto and Utzon, the following architects have used Critical Regionalism ( in the Frampton sense ) in their work: Studio Granda, Mario Botta, Mazharul Islam, B. V. Doshi, Charles Correa, Alvaro Siza, Jorge Ferreira Chaves, Rafael Moneo, Geoffrey Bawa, Raj Rewal, Tadao Ando, Mack Scogin / Merrill Elam, Glenn Murcutt, Ken Yeang, William S. W.

Ken Yeang is an ecoarchitect and an early pioneer of ecological design and planning, carrying out design and research work in this field since 1971.

Yeang now applies this concept of designing architecture as ' built ecological habitats ' to all his work.

This progressively developing body of work led Yeang to being recognized internationally as a pioneer, advocate, writer and innovator in authentic ecological design.

Many mistakenly regard Yeang ’ s work as simply placing vegetation in his builtforms or as just creating an ecological nexus ( continuous link ) within his builtforms to enhance local biodiversity.

Yeang ’ s work does much more than just that.

In achieving this, his built work become more than just ‘ vertically-landscaped architecture ’ but are in effect constructed ‘ living systems ’ ( See pages 252-253 in Hart, Sara, ' Ecoarchitecture – The Work of Ken Yeang ', publ.

This work in a relentless pursuit of an original biointegrated ' ecological aesthetic ' may be Yeang ’ s other significant contribution to this field.

Few architects design as well as build, teach, research and write – Yeang ’ s does all these prolifically and these in aggregate lends further credibility to his work.

There have also been several monographs authored by others on Yeang ’ s work since 1989 ( Robert Powell, Leon van Schaik, Ivor Richards and others ).

Yeang ’ s recent projects exemplify the maturing of his design work with a growing complexity and confidence in creating an ecoarchitecture with an evident luxuriant greening that defines and becomes his own identifiable architectural style.

Yeang and his ecodesigns have been featured in a number of special broadcasts, including BBC ( UK ) television and radio, NHK ( Japan ), Asia Discovery Channel ( Asia ), PBS ( USA ) ‘ design = e2 ’ ( in which the actor Brad Pitt refers to Yeang's work, '... wind, rain and the sun, in the minds of most architects, they are the enemies .. but what if buildings can utilise and respond to the conditions of the environment?

University of Washington's Professor Udo Kulterman states, “.. Professor Ken Yeang is internationally renowned as the ' father ' of the sustainable bioclimatic building ..".

Yeang works between the UK architect and planning firm, Llewelyn Davies Yeang ( as Design Director ( 2005 ) and Chairman, since 2010 ) and his Asia office, T. R. Hamzah and Yeang ( Kuala Lumpur, Malaysia ).

Dr. Ken Yeang (: 杨经文 / 楊經文 ; pinyin: Yáng Jīngwén ; born 1948 ) is a prolific Malaysian architect and writer best known for advancing green design and planning, differentiated from other green architects by his comprehensive ecological approach.

Yeang sees our existent built environment as having alienated humans from nature which needs to be rectified.

T. R. Hamzah & Yeang was formed in 1975 with Tengku Datuk Robert Hamzah, his friend and contemporary at the AA School, and a Prince in the Malay Royal family.

Yeang attended courses in ecology at the Department of Environmental Biology at Cambridge University ( under Professor J. W. L.

Around the 1990s, Yeang began to develop ideas for designing the high-rise with the intriguing proposition of looking at the high-rise typology as vertical green urbanism.

All of Yeang ’ s architecture and ecomasterplans have an internal as well as an external ecological connectivity within the built forms or masterplans that is connected to the landscape at the ground plane and where possible to the hinterland's natural landscape, and which further seek a benign and seamless biointegration between human activities and its built systems with the surrounding ecosystems in the landscape ( e. g. in the Zorlu Masterplan, Istanbul, Turkey ).

Yeang worked on the Great Ormond Street Children's Hospital Extension ( London, UK ) ( completed 2011 ) as a hyper green healthcare facility.

The UK Guardian newspaper ( January 2008 ) lists Yeang as '.. one of the 50 People who could save the Planet ..’,

John Wiley & Sons, UK ; and Yeang, K. ( 2009 ), Ecomasterplanning, Publ.

1990s architects such as William McDonough and Ken Yeang applied environmentally responsible building design to large commercial buildings, such as office buildings, making them largely self-sufficient in energy production.

Previous lecturers have included: Johan Galtung, Ken Yeang, Dr. M. S.

The debate about functionalism and aesthetics is often framed as a mutually exclusive choice, when in fact there are architects, like Will Bruder, James Polshek and Ken Yeang, who attempt to satisfy all three Vitruvian goals.

Among the plantations here were Teo Tek Ho estate and Hun Yeang estate.

Llewelyn Davies Weeks ( rebranded as Llewelyn Davies Yeang ) was founded in the mid-1960s by Lord Llewelyn Davies.

Yeang is best known for his deep green ecoarchitecture, ecomasterplans and ecocity designs that go beyond conventional rating systems such as LEED, BREEAM, etc.
