East River Tenant Corporation is a 166-unit market rate multifamily residential co-op in New York City managed by Wallack Management. Heating, cooling and domestic hot water was supplied by two original low-pressure steam boilers that produced steam for heating, domestic hot water and an original single-stage absorption chiller.

Objective

The building had been looking to reduce energy consumption, operating costs and environmental impact for its aging energy infrastructure.  As a result, they reached out to the En-Power Group for help to put together a cost effective solution.

Our Solutions

As a first step performed a comprehensive assessment of the properties current usage of energy and cost effective measures.  The assessment identified numerous cost effective energy savings measures that included boiler replacement, chiller replacement, lighting upgrades, domestic hot water heater upgrades, and the installation of a combined heat and power system.  The plan allowed us to prioritize the installation of measures combining them with available funding sources and available financial incentives.

Results

En-Power Group met the goal at an overall project cost of $1.7M, not including the CHP system and is being fully paid for by the annual energy savings. The new system reduced fuel consumption and operating costs by over 40% annually.  The project obtained over $100,000 in financial cash incentives towards the implemented measures.
