ASHRAE, the U.S. Green Building Council (USGBC) and the Illuminating Engineering Society of North America (IESNA) have announced that they will jointly sponsor the development of a new minimum standard for high performance green building.
The proposed Standard 189, Standard for the Design if High-Performance Green Buildings Except Low-Rise Residential buildings, will provide minimum requirements for the design of sustainable buildings to balance environmental responsibility, resource efficiency, occupant comfort and well-being, and community sensitivity. The proposed standard will use USGBC’s LEED Green Building Rating System, which addresses the top 25% of building practice as a key resource and will provide a baseline that will drive green building into mainstream building practices, according to the sponsors.
The proposed standard will apply to new commercial buildings and major renovation projects. Like the LEED standard, it will address sustainable sites, water use efficiency, energy efficiency, a building’s impact on the atmosphere, materials an resources, and indoor air quality. The standard will be an ANSI-accredited standard that can be incorporated into building codes. It is intended that in the future the standard will become a prerequisite under LEED. It is scheduled for completion in 2007.
Concurrent with the development of this standard, USGBC will begin development of LEED v3.0, which will include major advances in building science and technology, such as LifeCycle Assessment and bioregional weighting, according to Rick Fredizzi, president, CEO and founding chair of USGBC.
