Maria and Bonifacio Lopez installed a new boiler and made other energy-efficient upgrades to three dwelling units in their Providence, Rhode Island, home. This should save them $622 per unit annually, according to the National Energy Audit. The Lopezes worked with the Green & Healthy Homes Initiative, which streamlines local, state, and federal programs, serving as a one-stop shop for families in need of housing services to ensure their home is green, healthy, and safe.
