Prescriptive Standards

Prescriptive standards are a one-size-fits-all approach to sustainability. It does not address the concept of sustainability as it impacts each situation. Instead, the focus is on what you specifically should do and might be limited by one industry or concern. The beauty of LEED is that it has selected the monumental standards for each aspect of sustainability. In one case the expert might be the Environmental Protection Agency, in another it is the South Coast Air Quality Management District. In many cases it is the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). I have always been amazed how the USGBC has managed to select high standards from a number of industries and disciplines.
