Im an architect specialized on environmentally sustainable architecture with a focus on Low and zero energy builtforms. The first zero energy office building in Sri Lanka which was designed by me opens a new era in the field of Architecture in the country. I believe inorder to tackle the present environmental issues the architecture need the justifications not for its beauty but its performance. Optimized thermal performance in tropical buildings is the way forward in architecture of the contemporary world. The doctoral degree in architecture from the University of Queensland, Australia focussing on climate responsive arhitecture of sub-tropical climates paved a path to explore new themes in contemporary architecture. All sketch design are simulated for its thermal performance from the inception using the internationally accepted energy modelling softwares. Builtforms are truely a value for money spent where the operation of the building is free. Its a long term saving for the client.
