CEC Pioneers Multifamily Renewable Tech in NYC

         
Monday, May 4th, 2009


As part of our ongoing efforts to encourage sustainability in New York, Community Environmental Center recently completed the installation of a pilot solar thermal installation on two 6-unit buildings in Cypress Hills, Brooklyn, managed by the Cypress Hills Community Development Corporation.

CEC installed systems that pass glycol through flat plate solar collector panels to cope with New York’s winter freezes. The glycol then is pumped through the building into the boiler room and passes through a newly installed heat exchanger.  In the heat exchanger the glycol heats water that is circulated into the solar storage tank. The solar storage tank then provides pre-heated water for the existing hot water tank. The preexisting hot water tank will need to consume less energy in providing hot water for residents. Each installation took 3 days to complete.

boilercrewRon Kamen of EarthKind Energy provided valuable training and oversight for the CEC crew. The panels were installed by CEC. 

Cost of materials was $9,453 for 4 panel system with heat exchanger and solar water storage tank.

For 2829 Fulton Street, energy usage for hot water heating was estimated at 1600 therms.  The installation of 4 solar panels was estimated to reduce energy used to heat domestic hot water by 727 therms annually at a cost of $1.8 per therms for the 20 year life of the system.  The total savings over the life of the system would be $26,000.

779 Liberty Street had a lower overall energy usage.  Domestic Hot water was estimated to use 1,066 therms.  The similar installation was estimated to reduce energy usage 389 therms.   389 therms at $1.8 for the 20 year life of the system will save $13,000.
