ASHRAE Proposed Standard 189.1 - Standard for the Design of High-Performance Green Buildings Except Low-Rise Residential Buildings, is open for its second public review.
Being developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers Inc. (ASHRAE), the Illuminating Engineering Society of North America (IESNA) and the U.S. Green Building Council (USGBC), Proposed Standard 189.1 will provide minimum requirements for the design of high-performance new commercial buildings and major renovation projects.
According to ASHRAE, the standard addresses energy efficiency, a building's impact on the atmosphere, sustainable sites, water use efficiency, materials and resources and indoor environmental quality.
"This standard is an energy-saving stepping stone toward ASHRAE's goal of net-zero-energy buildings," said John Hogan, chair of the committee that wrote the standard.
"This is a goal that IESNA and the USGBC support as well as partners in this standard's development. It also gives building owners or jurisdictions that voluntarily choose to adopt the standard a tool for constructing truly high-performing buildings that provide energy-efficient, safe and comfortable environments for occupants," Hogan said.
According to ASHRAE, by applying the minimum set of recommendations, ASHRAE Standard 189.1P leads to site energy savings ranging from 10% to 41% over those provided by ASHRAE Standard 90.1-2007, including plug and process loads and all other energy consumption for the building, with an average of 24.9% for all climates.
The proposed standard also provides indoor water savings of 35% for an office building and 26% for a multifamily building, ASHRAE said.
The indoor air quality criteria are coordinated with the ASHRAE IAQ design guide (under development), and the commissioning criteria have been more closely aligned with ASHRAE commissioning guidelines.
