  • The goal of green design is to create high-performance buildings. Often called “sustainable design,” it evolved from a variety of concerns, experiences, and needs….. Energy efficiency gained importance during the 1970s oil crisis. Recycling efforts in the U.S. in the 1970s onward became commonplace and came to the attention of the building industry. In the 1980s, the “sick building syndrome” concept emerged and concern for worker health and productivity became an issue. The concern for toxic material emissions also became an issue that needed to be addressed. Projects in water-scarce areas began to focus on water conservation. Early green designs usually focused on one issue at a time, mainly energy efficiency or use of recycled materials. Green building architects in the 1980s and 1990s began to realize that the integration of all the factors mentioned here would produce the best results and, in essence, a “high performance” building.
