August 29, 2003—The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) is developing three sets of proposed documents to provide energy savings ranging from 30 percent to 75 percent over ANSI/ASHRAE/IESNA Standard 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings.
The proposed savings refer to reductions in energy consumption allowed by 90.1, which sets the minimum energy efficiency required by most building codes. For example, if a building built to the minimum requirements of Standard 90.1 uses 1 million units of energy, a building using 30 percent less would use 700,000 units of energy. These percentages also are approximations of the energy cost savings in dollars.
