High-performance green building standard released
Standard 189.1 will provide a strong foundation for high-performance green buildings.
A new standard for the design of high-performance green buildings is set to revolutionize the building industry. Published by ASHRAE, in conjunction with the Illuminating Engineering Society of North America (IES), and the U.S. Green Building Council (USGBC), Standard 189.1, Standard for the Design of High-Performance, Green Buildings Except Low-Rise Residential Buildings , is the first code-intended commercial green building standard in the United States.
The standard, published Jan. 22, 2010, provides a long-needed green building foundation for those who strive to design, build, and operate green buildings. From site location to energy use to recycling, this standard will set the foundation for green buildings through its adoption into local codes. It covers key topic areas similar to green building rating systems: site sustainability, water use efficiency, energy efficiency, indoor environmental quality, and the building's impact on the atmosphere, materials, and resources.
The energy efficiency goal of Standard 189.1 is to provide significant energy reduction over that in ANSI/ASHRAE/IESNA Standard 90.1-2007. It offers a broader scope than Standard 90.1 and is intended to provide minimum requirements for the siting, design, and construction of high-performance green buildings.
Standard 189.1 has been written by experts representing all areas of the building industry, including engineers, lighting designers, sustainability experts, building owners, designers, architects, code and compliance officials, utilities, materials experts, and equipment manufacturers. The technical requirements in the standard were also supported by input from the building industry during the public review process.
