Newly Released American National Standard

Thanks to the efforts of American National Standards Institute (ANSI) members and accredited standards developers ASHRAE, the U.S. Green Building Council (USGBC) and the Illuminating Engineering Society (IES), a newly revised American National Standard (ANS) is helping to improve energy efficiency and pave the way to a more sustainable energy future.

ANSI/ASHRAE/USGBC/IES Standard 189.1-2011, Standard for the Design of High-Performance, Green Buildings Except Low-Rise Residential Buildings, provides a green building foundation for those who strive to design, build, and operate high performance buildings. This American National Standard covers criteria including site sustainability, water use and energy efficiency, indoor environmental quality, materials and resources use, as well as a building’s impact on its site and its community. When first introduced in 2009, the standard was the first code-intended commercial green building standard in the United States. Please visit the ANSI website for more details.
