“Green building” is known as “environmentally symbiotic building” in Japan, “ecological” or “sustainable building” in some American and European nations and “green building” in North America. Green Building as a design concept originated in cold-climate advanced nation, so many of the design techniques are not entirely adaptable in the tropics or subtropics. In Taiwan, the word “green” is now synonymous with environmental conservation as demonstrated in buzzwords like “green consumption”, “green lifestyle” and “green lighting”. Taiwan has even adopted the vision of a “green silicon island” as benchmark for sustainable development. Therefore, it was decided to use the already well-known expression of “green building” to refer to eco-friendly buildings.
