Ken Yeang is an architect and ecologist best known for his ecology-based signature architecture, with its distinctive verdant green aesthetic and performance beyond green rating systems. Driven by a pioneering spirit, Yeang’s long involvement with sustainable design began in 1971 with his research work on ecological design. Since then he has developed ideas, principles and systems in ecological and bioclimatic architecture and master planning, contributing significant advances in this field evident in his design, research, built work and writings. He trained at the AA (Architectural Association School, UK) and received his doctorate from Cambridge University (UK) on ecological design and planning. His key buildings include Suasana Putrajaya (Malaysia), Solaris (Singapore), Menara Mesiniaga (Malaysia, a recipient of an Aga Khan Award), Genome Research Building (Hong Kong), and Great Ormond Street Children’s Hospital Extension (UK). He received the Malaysian Institute of Architects Gold Medal, the Government of Malaysia’s Merdeka Award, and the Architectural Society of China Liang Sicheng Award 2016. He has authored over 12 books on ecological design. The UK Guardian newspaper named him as one of 50 individuals who could save the planet. Edwina Threipland has considerable experience in zero-carbon buildings and high-specification housing schemes, having worked at ZEDFactory and KSR Architects.
