Located on Roosevelt Island, Roosevelt Landings is a one million square foot, nine-building affordable housing development. It is also the largest air sealing project in New York City. Owner, Urban American was interested in making deep energy improvements to the master-metered buildings, without making additional investment to the property. The project team, Harlem Greenfit Management (HGM), Urban Greenfit, and Steven Winter Associates, Inc. (SWA) worked together to complete a series of deep energy efficiency improvements, with nearly immediate results and lower operating costs.

SWA was tasked with developing a scope of work and financial model to upgrade the outdated systems and controls, insulate the poorly sealed apartments, and install a cogeneration system. Our team collaborated with project team member, Urban Greenfit, to devise a “turnkey” solution to the design, implementation, and financing of the retrofits.

The energy efficiency improvements featured the installation of a combined heat and power (CHP) plant and domestic hot water (DHW) boiler upgrade; electrical heat control with programmable thermostats; comprehensive air-sealing of the building envelope and interior spaces; floor-slab insulation; and, building operator and resident education.

During the winter of 2013-2014, nearly $500,000 in annual operating cost savings was delivered, meeting estimated projections — a laudable accomplishment since upgrades were completed well after the heating season began. The one million square foot complex was also the first multifamily project to utilize New York City Energy Efficiency Corporation (NYCEEC) financing.
