Low-income households who own and rent their homes in Philadelphia often live in older, less efficient homes, and less healthy homes. These households often struggle to maintain their homes or, as renters, are unable to make those investments. Living in poorly maintained homes has serious consequences for households’ cost of living, and their health and safety. Philadelphia is building programs to bring more investment to low-income households to make them more affordable, healthier places to live.


Built to Last Program

The Philadelphia Energy Authority (PEA), with the leadership of Councilmember Derek Green and a core group of coalition partners and advocates, is rethinking how Philadelphia can improve housing for low-income homeowners.

PEA is acting as an administrative backbone to allow housing programs to layer and streamline their services, and will add construction management services, additional grants and financing as needed. Built to Last seeks to restore the safety, health, affordability and comfort of existing affordable housing in a way that improves the long-term quality of Philadelphia’s housing, builds community wealth, and helps families avoid displacement and stay in their homes.

PEA began its first pilot in late 2021 and is in the process of servings its first 50 homes. Following completion of its initial pilot, PEA will undertake a second phase of 50 homes to further refine the Built to Last service delivery model.

For each phase, PEA will work with low-income homeowners who are living in neighborhoods with high poverty rates across the City of Philadelphia. PEA will assist the households with enrolling in all available benefits, evaluate their home restoration needs, and coordinate service delivery and supplemental funding. Pilot households will earn below 200% of the Federal Poverty Level and own their homes.

The Philadelphia Energy Authority strives to eliminate the financial barriers to energy upgrades by making clean energy accessible and affordable. Energy upgrades provide significant benefits to multifamily housing units, including increasing the property value, lowering its day-to-day operating costs, and reducing its carbon footprint. Multi-family buildings have unique features, financing structures, opportunities and requirements when it comes to energy efficiency.

Multi-Family Housing Pilot

PEA assembled a team for a multifamily pilot project, which is serving as the model for scaling up across Philadelphia. The implementation partners for the Multi-Family Affordable Housing Pilot are Mission First Housing Group, Friends Rehabilitation Program, BlocPower, CMC Energy Services, Stratis IOT, PECO Energy, and Philadelphia Gas Works. Phase 1 included auditing of the Mission First Housing Group and Friends Rehabilitation Program properties, totaling 189 units. CMC Energy Services collected key data on the properties and installed utility-funded measures to address electricity and gas consumption. Along with the energy conservation, CMC and Stratis IOT installed networked smart thermostats, which now allow BlocPower to collect aggregated and anonymous data on the conditions that tenants experience, which allowed BlocPower to refine their recommendations for larger investments in energy conservation.

PEA is leveraging the experience from the pilot project to provide technical assistance to property owners who are looking for ways to improve the energy performance of their buildings and to help cut utility costs for tenants.
