Stonepark Consulting led construction management, with EKA Contracting as the general contractor. Skyline Restoration handled the facade work, while NY Engineers provided engineering expertise, and Bertolini Architectural Works guided the architectural vision. Their combined efforts enabled a seamless transformation of the building’s climate control systems.
The project replaced outdated gas boilers and window ACs with 96 AIO Wall Mounted Pro Heat Pumps featuring 1,800W resistance heat, delivering room-by-room climate control and eliminating fossil fuels. The upgrade met NYC sustainability regulations and earned major NYSERDA incentives.
