Maria and Bonifacio Lopez of Providence, Rhode Island, made energy-efficient upgrades to their house, which is divided into three dwelling units. This should save them $622 per unit annually, according to the National Energy Audit Tool. 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 services to ensure homes are green, healthy, and safe.
