Durst Uses Off-Peak Cooling To Reduce Energy Costs
NEW YORK, NY — The Durst Organization, a major Manhattan commercial property owner, has chosen an Off-Peak Cooling (OPC) system to reduce the overall cost of energy in its 20-year-old building on the Avenue of the Americas.
The OPC system, supplied by Calmac Manufacturing Corp., Englewood, NJ, uses less expensive nighttime electricity to produce ice in 8-foot storage tanks. The ice is then used the following day to cool the building. Shifting the electric load from more costly on-peak hours to off-peak hours significantly reduces energy costs, since on-peak prices are at least double and can be up to 10 times the nighttime rate, according to Calmac.
