As building costs increase and infrastructure continues to age, one local nonprofit is working to reduce operating costs and provide energy- and cost-efficient homes for low-income residents. The New York office of Columbia, MD-based Enterprise Community Partners, Inc. has launched a new program called the Partner Portfolio Retrofit Engagement Platform – or PartnerPREP – a new green business service that will help owners of multifamily affordable housing developments to retrofit their buildings. The program provides owners with energy planning and building management advice, energy efficiency and building performance technical support and assistance in identifying financial opportunities and resources to support energy efficiency upgrades and improvements during the course of two years. Enterprise recently received a grant award of $2.8 million from HUD’s Energy Innovation Fund, of which $1 million will be used for the program. In addition, Morgan Stanley provided a $200,000 grant and the New York Community Trust donated $100,000 toward the work. Participants in the program include El Barrio’s Operation Fightback, South East Bronx Community Organization, Mutual Housing Association of New York and VIP Community Services, which comprise 2,500 units total.
