ATLANTA — ASHRAE has announced a newly published user’s manual that clarifies the intent and implementation of the ASHRAE/USGBC/IES green building standard by explaining its requirements and providing example applications.

The standard is published by ASHRAE, the U.S. Green Building Council (USGBC), and the Illuminating Engineering Society (IES). The User’s Manual to ANSI/ASHRAE/USGBC/IES Standard 189.1-2014, Standard for the Design of High-Performance, Green Buildings Except Low-Rise Residential Buildings, is intended to help engineers, architects, and contractors understand and comply with the standard and to help code officials and others enforce its requirements. This new User’s Manual updates the previous version.

Standard 189.1 addresses the areas of site sustainability; water-use efficiency; energy efficiency; indoor environmental quality; the building’s impact on the atmosphere, materials and resources; and construction and plans for operation. For more information on the standard, visit

“The 2014 standard updates the 2011 standard through 67 individual addenda that modified all sections of the standard,” said Andrew Persily, chair of the Standard 189.1 committee. “The User’s Manual is vital in helping the industry understand these updated provisions, which will help further reduce building energy and environmental impacts through high performance design, construction, and operation while providing indoor environments that support the activities of building occupants.”

The cost of the User’s Manual is $105 ($89, ASHRAE members).
