"Green standard" ASHRAE 189.1 goes online

February 24, 2010

Published by ASHRAE after four years of development, the new ASHRAE Standard 189.1 provides minimum requirements for the siting, design, construction, and plan-for-operation of high-performance green buildings.

As the first code-intended commercial green building standard in the United States, the new standard is developed in model-code language and applies to all buildings except low-rise residential buildings.

 In addition to mandatory provisions, the new standard provides prescriptive and performance options for all topic areas, which include:

 • Site Sustainability
• Water Use Efficiency
• Energy Efficiency
• Indoor Environmental Quality
• The Building’s Impact on the Atmosphere, Materials, and Resources
• Construction and Plans for Operation
