Many schools need help understanding the Clean Buildings Program’s compliance expectations. This Tier 1 & Tier 2 Factsheet provides requirements and compliance schedule information.

Tier 2 (20,000+ sf) compliance only goes so far as benchmarking (tracking energy usage). Tier 1 buildings (50,000+sf) are responsible for meeting an energy performance metric for their building by meeting an energy use intensity target (EUIt) or through the investment criteria.

Tier 2 schools will be sent a notification letter indicating their Tier 2 status in July 2025. Yet, the initial date to comply with requirements to track energy usage, establish a point person, and other compliance mandates is July 1, 2027, and every five years after that. The notifications will be sent to the building owner by the Department of Commerce, so schools that lease their property should be aware that the building owner will need the school’s partnership to meet compliance.

Schools needing support should contact their utility provider to learn about any programs for mentoring, such as:

PSE Clean Buildings Accelerator program

The Puget Sound Energy Accelerator Program is offered to Puget Sound Energy customers with Tier 1 buildings (50,000+ sf).
