ASHRAE 189.1: Complimenting LEED in a Mandatory Way?
01.28.10 8:57 AMASHRAE 189.1 was approved by ANSI on January 22, 2010, and published as a standard on January 26, 2010.
ASHRAE 189.1 is the fruit of the collaboration between the American Society of Heating Refrigerating and Air Conditioning Engineers (ASHRAE), the Illuminating Engineering Society of North America (IES), and the United States Green Building Council (USGBC). 189.1 is a new standard for the design of commercial High-Performance Green Buildings and is being finalized such that it can be adopted by states and incorporated into their building codes. This new ANSI standard, if adopted by a state, will apply to new construction and major renovation, except for low-rise residential buildings, and will address “site sustainability, water use efficiency, energy efficiency, indoor environmental quality (IEQ), and the building’s impact on the atmosphere, materials and resources.”
ASHRAE 189.1 was designed to provide a green foundation for buildings, and is set to compliment LEED requirements. Unlike LEED, however, ASHRAE 189.1 was created with an eye toward being incorporated into building codes, which would require mandatory compliance.
Many thanks to Angela Stephens for making us aware of this development!
