Interaction of Lighting, Heating and Cooling Systems in Buildings. Interim Report

摘要

The effect of interactions between building lighting, heating and cooling systems on the energy performance of the lighting system and cooling loads is examined, based on detailed full-scale measurements and supporting computer simulations. A test facility was designed, constructed and operated to emulate an office space with recessed fluorescent lighting. The test facility was extensively instrumented to monitor lighting power, cooling load, surface and air temperatures, heat flows and light levels. 398 measured parameters were averaged and recorded every two minutes during testing. The interim report describes preliminary results from the research effort. The results showed that the lighting system can be constrained to operate at its most efficient level, if the fluorescent lamps are cooled sufficiently. A two-term exponential relation with four regression coefficients was found to fit the measured data well.
