Proposed Standard 189.1 Begins Third Public Review with Increased Energy Savings

With additional energy savings over the previous draft, the nation's first standard for high-performance green buildings began its third public review period May 1.

Proposed Standard 189.1, Standard for the Design of High Performance, Green Buildings Except Low-Rise Residential Buildings, is being developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) in conjunction with the Illuminating Engineering Society of North America (IESNA) and the U.S. Green Building Council (USGBC). When completed, it will address energy efficiency, a building's impact on the atmosphere, sustainable sites, water use efficiency, materials and resources, and indoor environmental quality, among other high-performance green building issues.

The third public review draft has been reorganized to be more user-friendly while focusing on delivering and maintaining energy and water efficiency performance over the life of the building. Compared to the previous draft, this draft provides increased energy savings over ANSI/ASHRAE/IESNA Standard 90.1. Comments on the draft standard will be accepted through June 15.
