Presented here are some of the devices used by Ken Yeang in his endeavors to take his theoretical work on ecoarchitecture into the real world of building. The fundamental underlying premise is that ecoarchitecture, if it is to fully embrace the natural world, must be designed to be ‘living constructed ecosystems’ and not inert denatured structures. Yeang holds that green design today is still very much in its adolescence, requiring significant developmental work, particularly in architectural biointegration and aesthetic development. Shown and explained here are the various invented devices that Yeang has adopted to technically advance his ideas from the abstract theoretical level, through concept architectural design to the level of microdevices and building sub-systems to achieve a better biointegration of our human built environment with nature.
