On 1 February 2016, ASHRAE announced the publication of a User’s Manual which clarifies the intent and implementation of the building industry’s foremost green building standard by explaining its requirements and providing example applications.


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, as well as to help code officials and others enforce its requirements. This new version of the User’s Manual updates the version published in 2010, which covered the content of Standard 189.1-2009.


Standard 189.1 addresses the following areas:


  • 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. 


The Standard is published by ASHRAE, the Illuminating Engineering Society (IES) and the U.S. Green Building Council (USGBC).
