Riverpoint Towers is a 320,000 square foot, 25 floor, multi-family residential cooperative built in 1965 in NYC. The site also contains a large swimming pool located on the north side of the building which is both shaded by the building and receives significant amount of wind. The building is managed by an on-site resident manager, with oversight by a resident board. The building contains a central utility plant located in the basement that provides heating, cooling and domestic hot water. Heating was supplied through hot water that is circulated to individual floor and tenant locations. Heating and hot water were produced by two duel-fuel steam boilers that convert the steam to hot water through heat exchangers located adjacent to the boiler room. Chilled water was produced in an 800-ton single-stage steam absorption chiller.

Objectives

Riverpoint Towers hired En-Power Group to recover incentives for the heating, cooling, and CHP system to maximize savings to all shareholders.

Our Solutions

Due to the age of the building’s existing equipment, the facility replaced the existing chilled water equipment with new, natural gas-fired TECOCHILLERS and installed a combined heat and power TECOGEN system to provide electricity, heating and cooling for the facility. The upgrades were performed under an energy purchase agreement that required no financing at all from the facility.

The project is currently installed and fully operational, and En-Power Group also developed final commission reports to meet NYSERDA program requirements.
