ASHRAE outlined and updated the press with recent changes made to the Standard 90.1.
At the AHR Expo, ASHRAE briefed the press on recent updates made to Standard 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings. Michael Rosenberg and Bing Liu, both from Pacific Northwest National Laboratory and the 90.1 committee, provided highlights of the updated standard.
The changes in 90.1-2016 include 121 addenda; major format changes for ease of use; new climate maps aligning with ASHRAE Standard 169; a new performance-based compliance path (Appendix G, which is similar to Energy Cost Budget but more flexible); and significant whole building energy savings.
Compared to 90.1-2013, the updated standard saves 6.8 percent more energy on average for a whole building. The next version of the standard is scheduled to be released in 2019.
