Washington Clean Buildings Performance Standard


The Clean Buildings Act (HB-1257), which was recently passed in Washington State, intends to curb energy usage for large commercial buildings over the next few years. All commercial buildings over 50,000 SF will be required to comply with the standard following the timelines below. Buildings that do not comply will be assessed a financial penalty based on facility size which could be substantial and is recurring on a five year basis.

Compliance Dates:

Buildings over 200,000 SF: June 1, 2026

Remaining Buildings over 90,000 SF: June 1, 2027

Remaining Buildings over 50,000 SF: June 1, 2028

Compliance is determined by calculating both a facility's Energy Use Index (EUI) and Energy Use Index Target (EUIt) and comparing the values. This process may be simple if your facility is currently meeting the target, but can get complicated and involved very quickly.

If your building is not currently meeting it's EUIt, an ASHRAE Energy Audit is required. This is a time-intensive process that must be performed by qualified personnel, that will look for any sources of efficiency loss in your building. The output of the Energy Audit is a list of Energy Efficiency Measures (EEM's) that you can choose to implement that will drive your EUI down towards meeting your EUIt.
