Energy Efficiency + Nonprofit = Savings for Lengyel House


Project Profile

"This project was a win-win for our non-profit as it  enabled us to upgrade and replace the building’s outdated infrastructure, including windows, and also reduce our energy costs without overburdening our budget. A-Home is now saving money, and our tenants are benefiting from a much more comfortable home." ~Gerry Granelli, Property Manager; A-Home

Energize NY provided $77,000 to A-HOME to pay for energy efficiency upgrades to an 4,900 sq ft, 8 unit multifamily home for adults with disabilities, known as Lengyel House, in Lewisboro, NY owned and operated by A-HOME, a not-for-profit that rehabilitates, builds and manages affordable rental properties in northern Westchester for older adults, disabled individuals and single-parent families who cannot afford market rate housing. 

The efficiency measures included air sealing; insulation of exterior walls, attic and crawl spaces; new high efficiency boiler and replacement of old windows. 

Like all projects financed by Energize NY, the A-HOME project was cash flow positive on day one, with the energy savings exceeding the cost of the improvements and the financing.

News Coverage


“We especially appreciate the efforts of County Executive Astorino and the Westchester County Legislature in making QECBs available to further reduce the cost of financing energy efficiency and renewable energy projects for multi-family affordable housing buildings and not-for-profits.” ~Mark Thielking, Executive Director, Energize NY

The A-HOME project was even more cost-effective through the use of the $4 million Qualified Energy Conservation Bonds (QECBs) pool made available by Westchester County for energy upgrades to multi-family buildings with low-income tenants and buildings owned by not-for-profits.  

Westchester buildings that meet affordable housing guidelines or are owned by a not for profit corporation may qualify for reduced cost financing under Energize NY Finance: The Westchester Project.

Westchester County has teamed up with Energize NY to provide low cost financing that helps lower energy costs for properties that need it most: multifamily affordable housing and not-for-profit owned buildings. The county is utilizing its federally allocated Qualified Energy Conservation Bond (QECB) authority and aligning with Energize NY’s goal to promote energy efficiency and renewable energy projects.  This partnership presents an opportunity for property owners in Westchester County to significantly lower their energy costs and reduce energy waste in their buildings.
