Housing Preservation & Development


Resilient & Equitable Decarbonization Initiative (REDi)


Overview: To reach New York City and New York State’s ambitious climate targets and to reduce the barriers to decarbonizing affordable housing, HPD’s REDi program provides funding to build capacity and scale up equitable decarbonization, beneficial electrification, and resiliency within the HPD development pipeline and as outlined in HPD’s Design Guidelines. The REDi program is a long-term joint HPD-NYSERDA initiative that builds on HPD’s highly successful Retrofit Electrification Pilot and other joint programs and is an innovative model for streamlining access to financial and technical assistance from New York State. REDi funding is secured directly through HPD, without requiring an application to NYSERDA.

REDi: Existing Buildings (REDi: EB) is the first initiative to launch under the REDi program, with a goal of scaling up beneficial electrification within HPD’s multifamily retrofit pipeline. Similar to HPD’s Retrofit Electrification Pilot, this program will fund electrification of domestic hot water (DHW) and space heating/ cooling but adds additional funding for enhanced envelope and ventilation and provides higher per/project funding limits. This program will be open to eligible multifamily Preservation projects seeking HPD Preservation financing that are aiming to close on HPD financing after January 1, 2025, until funds are exhausted. Note that projects that have already applied to the HPD Retrofit Electrification Pilot will not be eligible.

Supported Scopes: Projects will implement one, two or all three of the pre-defined REDi: EB scopes. The borrower’s project team will work closely with the program’s dedicated NYSERDA Technical Assistance Provider (TAP) to design and scope the project and estimate project costs and energy savings. The TAP will also assist with bidding and procurement, monitor construction of the REDi: EB Scope, and train building residents and staff on system use and maintenance. In addition to electrifying DHW and/or heating systems and/or achieving advanced envelope and ventilation, projects will be required to install compatible energy efficiency measures and comply with all requirements as outlined in the REDi: EB Program Term Sheet and including all applicable Technical Requirements.

Funding: Funding is available to cover the incremental construction costs required to electrify DHW and space heating and to improve envelope performance. Funding will be provided on a first come, first served basis, and will be used to offset the REDi scope items. REDi: EB funding matches HPD subsidy and will be placed in the project’s servicing account alongside all other sources. Funding may be drawn down during construction through the normal requisitions process and as outlined in the REDi: EB Participation Agreement. Because funding is limited, there are per building limits and per project caps for multi-building projects. Details and program requirements are provided in the REDi: EB Program Term Sheet.

Program Priorities: EB program prioritizes projects where electrification is most beneficial and cost effective, which includes:

Heating systems that use oil or electric resistance as a primary heating fuel

Steam heating systems that require replacement or extensive modification

Domestic Hot Water systems requiring replacement in buildings < 7 stories that use oil or electric resistance

Heating and Domestic Hot Water systems located in basements and cellars in flood-prone buildings where electrification will protect equipment from flooding

Program Eligibility: HPD multi-family (5+ units) projects receiving city subsidy through an eligible HPD Program are eligible to apply for REDi funding. Funding is sourced from the utility System Benefit Charges (SBC) and as a result, the project must be served by Con Edison. Buildings receiving REDi funding may not also receive incentives from the following programs (or successor programs) in conjunction with program funding:

The HPD Retrofit Electrification Pilot or HCR’s Clean Energy Initiative (CEI)

Con Ed Affordable Multifamily Energy Efficiency Program (AMEEP)

NYS Clean Heat

Other implementation incentive programs administered by NYSERDA without written approval from HPD and NYSERDA.

For multi-building projects, Utility or other NYSERDA funding may be used to offset costs on any buildings (e.g., in multi-building projects) not receiving REDi: EB funding.

Note that projects may also seek NYSERDA’s Flextech funding to cover up to 75% of the cost for a targeted study on how best to implement clean energy and/or energy efficiency technologies into their project.

To Apply

Projects will be directed to apply to the REDi: EB after completing their HPD Pre-Scoping consultation and once HPD determines REDi program eligibility. The project team will use the REDi Application Form on the HPD Preservation Design Guidelines Workbook to assess the compatibility of the project with the REDi:EB Program, and submit it, along with their IPNA and 2 years of utility bills, to HPD Sustainability, at sustainability@hpd.nyc.gov for further review and approval.
