Project Background 

Located on Roosevelt Island, Roosevelt Landings is a one million square foot, nine building affordable housing development, as well as 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 investing additional cash in the property. The project team, Harlem Greenfit Management (HGM), Urban Greenfit, and Steven Winter Associates (SWA) worked together to complete a series of deep energy efficiency improvements, with almost immediate results and lower costs.

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


Project Services 

SWA was challenged with developing a scope of work and financial model to upgrade the outdated systems and controls, insulate the poorly sealed apartments, and install a cogeneration system.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