Washington state is providing assistance to eligible building owners that comply with energy performance standards in advance of mandatory deadlines. Early compliance will reduce greenhouse gas emissions and save energy consumption, which also will save operating costs. The Clean Buildings law, which authorized the program, requires certain commercial buildings to comply with state energy performance standards. This standard is based on ANSI/ASHRAE/IES Standard 100–2018, Energy Efficiency in Existing Buildings with amendments.
Through a partnership agreement, ASHRAE has developed a custom version of Standard 100-2018 incorporating the state-specific changes, to be readily used by building owners, engineers, and facility managers to comply with the Washington Clean Buildings law. This customized version will also facilitate the early adoption path.
Washington state’s mandatory building performance standards for existing buildings is the first statewide rule, with ASHRAE’s standard providing a vital technical underpinning. Improving the energy performance of existing buildings is critical to reducing carbon emissions and ASHRAE Standard 100 will help the state achieve its important climate objectives.
“This collaboration between ASHRAE and Washington state is an example for other states to follow with regard to improving energy performance in existing commercial buildings,” said 2021-22 ASHRAE President Mick Schwedler, P.E., ASHRAE fellow, LEED AP. “We are excited to partner with Washington state in implementing its statewide building performance standards.”
“Washington is proud to be implementing the nation’s strongest Clean Buildings law,” said Washington State Commerce Director Lisa Brown. “Our 2021 State Energy Strategy identifies energy efficiency in buildings as an essential strategy for transforming and decarbonizing our energy future. Investing in energy efficiency will strengthen local communities and help businesses lower energy costs.”
Some targets of the standard include the following:
As the standard is utilized, ASHRAE will collaborate with the Washington State Department of Commerce on specific educational opportunities related to Standard 100 and Standard 211, also adopted in Washington state’s clean buildings bill.
