Biography
Formative Years
Born in Penang, Malaysia, he attended Penang Free School (1961-1962) and entered Cheltenham College (Gloucestershire,1962-1967).[2]
He qualified in architecture from the AA (Architectural Association) School of Architecture (London) where he did freelance illustrations and graphic work for the AD, AAQ magazines and for the AA. His dissertation at Cambridge University, "A Theoretical Framework for Incorporating Ecological Considerations in the Design and Planning of the Built Environment" earned him a PhD, published as ‘Designing With Nature’ (McGraw-Hill, 1995)[3] and as 'Proyectar Con La Naturaleza’ (Gustavo Gili, SA, 1999). Academically, he holds the Distinguished Plym Professor chair (University of Illinois, USA, 2005). His honorary degrees include D.Litt.(Hon.) (Sheffield University, UK 2004), PhD (Hon.) (University of Malaya, 2013), D. Arch (Hon.) (Universidad Ricardo Palma, Peru 2016), D.Sc (Hon..) (Taylors University, Malaysia 2017).
Yeang attended courses on ecology (Department of Environmental Biology at Cambridge University), partial attendance in ecological landuse planning (Department of Landscape Architecture, University Pennsylvania, under Ian McHarg). These provided the ecological basis for Yeang’s work and work on his biodiversity and ecomimicry approach to ecological architecture and masterplanning, joining the British Ecological Society in 1975. Other courses attended includes business management at the Malaysian Institute of Management, the Singapore Institute of Management and a short course at Harvard Business School.

Work on Ecological Design
Yeang's research and technical work is in ecological architecture and masterplanning, establishing the formal basis for design, focussing on the biointegration of the human-made with nature, creating hybrid systems as ‘constructed ecosystems’. His work adopts bioclimatic design (climate-responsive passive low-energy) as a subset to ecological design, providing for him an underlying armature for ecological design. The approach also engenders critical regionalist features where climatic responses provide the links to its locality.
A key project is Yeang’s own house, the 'Roof-Roof' House (1985) which is his early experimental bioclimatic built work. The dwelling has an identifiable curved louvred umbrella-like upper roof-structure that functions as a solar-filtering device and device that shades the building's lower roof terrace. Its side 'wind wing-walls' directs wind into the dining area. The swimming pool on the east functions as an evaporative-cooling device bring in the predominantly easterly breeze into the adjoining internal living spaces. The many features make the building an instructive reference prototype for his subsequent work on climate-responsive and ecological architecture. Influences can be further found in Yeang's later building and planning work. Yeang applied the bioclimatic passive-mode principles to the high-rise tower typology. Contending that the high-rise tower as an intensive built form will not go away overnight because of its existent economic basis arising from high urban land values and ability to accommodate rapid urban growth. He sought ecologically benign ways to make this built form green and humane to inhabit. Professor Udo Kultermann (Washington University) credits him as the inventor of the 'bioclimatic skyscraper',
The Mesiniaga Tower (an IBM Franchise, 1992) brought together earlier experimental bioclimatic ideas in a single built form, such as the placement of the elevator core as a solar buffers to the tower's hot sides, placement of toilets and stairwells with natural ventilation opportunities, adopting various solar-path shaped sun-shades, use of an evaporative-cooling pool at the uppermost level, the overhead louvred canopy as a framework for future PV cells, and the vegetated and stepped façade and recessed sky-terraces as interstitial semi-enclosed spaces for building's users. This building as a prototype received several awards including the Aga Khan Award for Architecture (1993), The Malaysian Institute of Architects Award, the Singapore Institute of Architects Award, The Royal Australian Institute of Architects Award and a citation from the American Institute of Architects (AIA).
The Solaris building (Singapore, 2008) brought together his ideas on ecological architecture with a continuous landscaped ramp and other experimental devices. His ideas for an urban park-in-the-sky in the high-rise building type is manifested as a 'vertical linear park' in his Solaris Building (2011) at 1-North Singapore that is a benchmark building in his green agenda for designing buildings as bioint gratin with nature. The building has an ecologically-linked vegetated pedestrian walkway ramp that is 1.3 km in length as a 'vertical linear park', punctuated by sky garden terraces located at each of the building's corners, further linked to a mid-level and to the uppermost-level roof gardens.
His work on biodiversity and systemic biointegration were implemented in the Suasana Putrajaya (Putrajaya, 2017) based on a 'biodiversity targets matrix' originally proposed for the GyeonGgi Master Plan (Seoul, Korea).
The Solaris' vertical linear park device led to his concept of the continuous 'green eco-infrastructure', a device that enables a vital ecological nexus between the built form and its surrounding landscape, bioregion and its hinterland, that became habitats and a crucial biodiversity and wildlife corridor in all his subsequent masterplanning and eco-city design work (e.g. the SOMA Masterplan in Bangalore, India) and in his architecture (e.g. the Spire Edge Tower, in Gurgaon, India, completion c. 2015). This green eco-infrastructure concept led to his developing a unifying platform for eco-master planning as the weaving together of 'four sets of eco-infrastructures' into a unified system.
Yeang work on the high-rise typology as 'vertical green urbanism' (c.1990’s) sought to reinvent the skyscraper as 'vertical urban design'.[4] His ideas invert the high-rise typology as a 'city-in-the-sky', first exemplified in the National Library Singapore (2005). The building features large 40m high 'public realms-in-the sky' as verdantly landscaped 'skycourt gardens', a ground plane as an 'open-to-the-sky' plaza for public festivals and culture-related activities. The thickened first floor slab over the plaza functions biol climatically as an evaporative-cooling mass to the public realm below. Multiple upper-level sky-bridges link the building's two blocks (one containing the book collections and the other shaped block for programming activities. The naturally-ventilated atrium between the blocks has a ventilating louvred canopy that serves as its 'fifth facade'. There are two multi-volume reading rooms are located at either sides. At the uppermost roof is a promontory viewing pod. The building's built form has an organic geometry in his ongoing explorations to derive an ecological aesthetic (see below). The building received Singapore’s BCA Green Mark Platinum rating.
Yeang worked on the Great Ormond Street Children's Hospital Extension (London, UK) (completed 2011) as a green healthcare facility in a temperate climate. The building has a mixed-mode flue-wall providing natural ventilation during the mid-seasons to the Walt Disney operated ground floor Café, a sedum-planted roof, with various low energy building systems (CHP, etc.), use of green materials, etc. The building is BREEAM rated 'excellent'.
His work on the development of a 'platform' for eco-master planning and designing eco-cities regards designing the built environment as 'a living system' that is both interactive and functional through the bio-integration of the 'four eco-infrastructural armatures' into an overall coherent system The approach provides an indeterminate framework enabling inclusivity of changing complex factors and technologies in a flexibility that allows for technological obsolescence while encouraging innovation.[5]
A theoretical rigorousness underpins his work. His earlier Cambridge doctoral dissertation (1975) presents a unifying comprehensive theoretical model for eco-design defining the prime factors in eco-design in four sets of interdependent 'environmental interactions', assembled in a mathematical 'partitioned-matrix'. This theoretical model continues to serve as the underlying guiding framework for his present eco-architecture and eco-master planning work.
The impact of Yeang's work on architecture is based on his patterns of biointegration of biotic constituents with the inorganic structure of the built environment. The approach involves creating viable habitats within the development and then matching these with selected native fauna species whether for feeding, breeding or refuge to enhance local biodiversity. These are matched with selected flora species in a composite 'biodiversity matrix '. This endeavour takes eco-design beyond accreditation systems, likely as the next stage in green design, redefining the relationship of the built systems with the ecology of the landscape, enabling a higher level of bio-integration.
In Yeang's oeuvre of design, built and theoretical work, his most important and instructive contribution is his advancing the macro ecology-based land use planning approach of the landscape architect Ian McHarg and in extending and articulating this from its macro urban regional scale to the micro level of architectural design at the scale of the built form using his biointegation patterns. This was an endeavour that McHarg had sought to do but unable likely limited by being a landscape architect.
His recent work explores the concept of 'eco-mimicry' as designing the built environment as constructed ecosystems that emulates the processes, structure and attributes of ecosystems. ‘Eco-mimicry’ is a concept he first used in his papers on the use of biological analogies in design in Yeang, K.(1972), Bases for Ecosystem Design, in Architectural Design, Architectural Press, London (1973)), and in Yeang, K. (1974), Bionics: The Use of Biological Analogies in Design, in AAQ No.4 (Architectural Association Quarterly), London, UK, The ideas can also be found in, Learning From Nature: The Ecomimicry Project (Marshall, Alex, poster paper, Environmental Education conference, Western Australia (2006). The term 'eco-mimicry' is regarded by Yeang as an outgrowth from the ‘bio-mimicry’ and 'eco-mimetics'. Yeang's eco-mimicry refers to physical, structural and systemic mimicry of ecosystems, and not to be mistaken with a simplistic 'visual' mimicry which he regards as superficial.
Many 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 the addition of greenery and landscaping in his builtforms. The unique factor is involves the creation of new habitats within and around the development, matching of selected native species with these constructed habitats, setting their ‘biodiversity targets’ to achieve the expected level of biodiversity and providing physical conditions within these habitats to enable the selected species to survive over the seasons of the year. His built work become more than just ‘vertically-landscaped architecture’ but are in effect constructed ‘living systems’.[6] This differentiates his work from others who imitate his work by just placement of planting within their built forms.
