Isles, Inc. operates a project called ReHEET (Residential Health, Energy and Environmental Transformation) with funding from the New Jersey Neighborhood Revitalization Tax Credit (NRTC). ReHEET was created to pilot the joint provision of weatherization, structural repair, and healthy homes services in Trenton. The program collaborates with community groups to identify old, substandard, leaky homes in the Trenton region. It tests and repairs occupied homes for energy and health hazards. ReHEET received funding from 2010-2016 and completed 179 units over this period.
