Existing Multifamily Buildings (Washington)

Increasing energy efficiency in multifamily properties can reduce operating expenses, raise tenant satisfaction and improve building marketability. Energy Trust offers cash incentives for energy-efficient equipment and retrofits at existing multifamily properties with two or more units. When you install energy-efficient equipment, you’ll see savings that can help your building stand out in a competitive market, and contribute to tenant comfort and lower energy bills.
