Addenda to ASHRAE/IES Energy Standard Open for Comment
Some addenda open until Oct. 4, others open until Oct. 19
ATLANTA — Twenty-three addenda to the energy standard published by ASHRAE and the Illuminating Engineering Society (IES) — ANSI/ASHRAE/IES Standard 90.1-2013, Energy Standard for Buildings Except Low-Rise Residential Buildings — are currently open for public comment.
Among the addenda open for comment is addendum br, which was developed in response to the publication of ANSI/ASHRAE Standard 169-2013, Climatic Data for Building Design Standards. Standard 169 includes more-recent weather data (resulting in changes in climate zone assignments for some locations, including approximately 10 percent of the 3,000 counties in the United States) and the creation of a new Climate Zone 0. The proposed addendum adds requirements for mechanical provisions.
