Nov. 16, 2012: Additional Compliance Path Proposed for ASHRAE/IES Energy Standard
ATLANTA — A proposed optional third path for compliance with the ASHRAE/IES (Illuminating Engineering Society) energy standard is open for review. ASHRAE announced that addendum bm to ANSI/ASHRAE/IES Standard 90.1-2010, Energy Standard for Buildings Except Low-Rise Residential Buildings, is open for public review until Nov. 26, 2012.
The proposed addendum would add a compliance path to Standard 90.1 to allow modeling in accordance with Appendix G (Performance Rating Method), provided the percentage improvement of at least 45 percent over a baseline design. In addition, this addendum proposes to make the baseline consistent with the prescriptive requirements of 90.1-2004, and it will remain that way in future versions of the standard.
