Take control of tenant comfort by weatherizing your multifamily property. Air leaks and insufficient insulation contribute to drafts and uncomfortable temperatures. We offer incentives for window retrofits and insulation upgrades to help you improve tenant comfort and reduce energy use. Upgrades are available for owners of electrically heated apartment buildings, condominiums, retirement communities, and/or cooperatives with 5 or more units located in the our service area.
