NAVIGATING HB 1390
HISTORY OF HB 1390
The Clean Buildings Act was passed in 2019 to address greenhouse gas emissions related to the built environment. According to the WA State Department of Commerce, buildings account for 27% of all greenhouse gas emissions in WA state and are the fastest-growing emission source. To curb these emissions, the legislature passed HB 1257 in 2019 to create an energy performance standard for non-residential buildings and approved further expansions in 2022. HB 1390 was passed in 2023, amending the Clean Buildings Act and continuing the effort in Washington State to decarbonize campus buildings to achieve the state’s climate goals. This bill applies to campus energy systems which are defined as a collection of buildings served by a district heating, cooling, water reuse, or power system. HB 1390 offers an alternative compliance pathway to the state energy performance standard as outlined in HB 1257.
WHO DOES THIS APPLY TO?
1. Mandatory for state campus district energy systems.

• A state campus district energy system is defined as a collection of 5 or more buildings with more than 100,000 square feet of combined conditioned space owned by the state of Washington or any publicly owned properties that include a public-private partnership.
2. Optional for campus district energy systems.
• A campus district energy system is defined as a collection of 3 or more buildings with more than 100,000 square feet of combined conditioned space owned by a private entity or a public-private partnership where the public entity owns the building and the private entity owns the energy system.
