WSHFC Sustainable Energy Program

The Sustainable Energy Trust offers low-interest loans up to $1 million for energy upgrades to multifamily properties or nonprofit facilities—but single-family homeowners cannot borrow directly under this program. If you own a multifamily building or nonprofit facility in Washington, eligible projects must reduce utility consumption by at least 10%, and loans are typically structured so monthly payments stay below your utility savings. To apply, work with a contractor or energy auditor who verifies the energy savings, then contact WSHFC at energy@wshfc.org or (206) 254-5359.

The SET program finances energy-efficiency and renewable-energy projects for multifamily housing owners, nonprofit facilities, businesses, and developers—giving your customers access to loans up to $1 million at favorable rates over 10–15 years. You'll need to conduct an energy audit or analysis demonstrating at least 10% utility consumption reduction (for efficiency projects) or performance verification for clean energy installations; third-party verification is required. Partner with borrowers early in the design phase and direct them to contact energy@wshfc.org to begin underwriting.

SET provides non-recourse financing up to $1 million across three categories: (1) new construction exceeding WA Energy Code by 12% for housing developers; (2) efficiency/water upgrades for multifamily and nonprofits achieving ≥10% consumption reduction, often structured as on-bill repayment; and (3) clean energy (solar, wind, biomass, CHP) for multifamily, nonprofit, and business owners. Loans carry favorable rates and 10–15 year terms, subject to underwriting. The program targets multifamily affordable housing, nonprofit facilities, and clean-energy deployment; single-family homeowners are excluded. Projects exceeding $1 million may access bond financing or co-lending partnerships; refer to energy@wshfc.org or (206) 254-5359.
