The engineer on a class-A 200,000-sf office tower project in a hot, humid climate has proposed a co-generation system that would burn natural gas to provide electricity, cooling, heating, hot water, and dehumidification of outside air. She has projected that the gas-turbine powered electric generator will supply more than half of the building's electrical energy in an average year. The waste heat from the turbine exhaust will be used to drive an absorption chiller for cooling the building without the use of CFCs or HCFCs. This waste heat will also be used to dry the desiccant wheel that will dehumidify outside air, thus dramatically reducing cooling loads.
