USE OF BUILDING THERMAL MASS TO OFFSET COOLING LOADS.

Author(s) : RUUD M. D., MITCHELL J. W., KLEIN S. A.

Summary

RELATIVELY FEW EXPERIMENTAL RESULTS HAVE BEEN PUBLISHED ON THE USE OF BUILDING THERMAL MASS TO OFFSET DEMAND. THE USE OF OFF-PEAK COOLING TO EXTRACT HEAT FROM A BUILDING STRUCTURE MAY INCREASE THE TOTAL ENERGY USE, WHILE AT THE SAME TIME REDUCING PEAK COOLING LOADS AND COOLING COSTS. THE PAPER DESCRIBES A PROJECT ON THERMAL STORAGE IN A BUILDING. ITS PURPOSE WAS TO EVALUATE THE EFFECT OF BUILDING THERMAL ENERGY STORAGE ON THE PEAK COOLING LOAD. TWO EXPERIMENTS WERE PERFORMED ON THE INDEPENDENT LIFE INSURANCE BUILDING LOCATED INN FLORIDA. THE OBJECTIVE WAS TO < PRECOOL > THE BUILDING AT NIGHT AND DURING THE WEEKEND TO REDUCE DAYTIME COOLING LOADS. DIURNAL HEAT CAPACITY CALCULATIONS WERE USED IN ANALYZING THE EXPERIMENTAL RESULTS. THE RESULTS SHOWED AN18 % REDUCTION IN COOLING ENERGY SUPPLIED DURING THE DAYTIME. THERE WAS NO REDUCTION IN PEAK DEMAND.
