Clean Buildings

On May 7, 2019, the Clean Buildings bill (HB 1257, 2019) was signed into law. The objective is to lower costs and pollution from fossil fuel consumption in the state’s existing buildings, especially large commercial buildings. The law requires the Washington State Department of Commerce to develop and implement an energy performance standard for these buildings and provide incentives to encourage efficiency improvements.
