Building performance is a growing priority for multifamily properties, especially when upgrades can reduce operating costs and improve resident comfort. Multifamily property owners and managers throughout Oregon and Southwest Washington are looking for practical improvements that help their buildings run more efficiently, reduce maintenance headaches and support a better tenant experience.
For more than two decades, Energy Trust of Oregon has helped multifamily properties complete energy-efficient equipment upgrades through technical support and cash incentives that offset project costs.
In 2026, Energy Trust is updating its incentive offerings, including new incentives and adjustments to existing ones, to help properties plan and complete high-impact improvements.
