C.O.P. (Coefficent of Performance)

Coefficient of Performance is the ratio of the rate of heat delivered versus the rate of energy output in consistent units. Or a complete, operating heat pump system operating under design conditions.

Caulking

Commissioning

Cooling Waste Heat Recover or Process Heating

An energy conservation system whereby some space heating or water heating is done by actively capturing byproduct heat that would otherwise be ejected into the environment. In nonresidential buildings, sources of waste heat include refrigeration/air-conditioner compressors, manufacturing or other processes, data processing centers, lighting fixtures, ventilation exhaust air, and the occupants themselves.
