REDUCING ENERGY COSTS AND PEAK ELECTRICAL DEMAND THROUGH OPTIMAL CONTROL OF BUILDING THERMAL STORAGE.
Author(s) : BRAUN J. E.
Summary
THE PAPER DESCRIBES AN INVESTIGATION INTO THE USE OF BUILDING THERMAL CAPACITANCE AS A MEANS OF REDUCING THE OPERATING COSTS ASSOCIATED WITH MAINTAINING ADEQUATE COMFORT CONDITIONS IN BUILDINGS. THE STATE OF THE BUILDING THERMAL STORAGE CAN BE CONTROLLED THROUGH VARIATIONS OF THE ZONE TEMPERATURES OVER TIME WITHIN THE THERMAL COMFORT REGION. THE APPROACH UTILIZED WAS TO APPLY DYNAMIC OPTIMIZATION TECHNIQUES TO COMPUTER SIMULATIONS OF BUILDINGS AND THEIR ASSOCIATED COOLING SYSTEMS FOR A RANGE OF CONDITIONS IN ORDER TO DETERMINE THE MAXIMUM POSSIBLE SAVINGS. RESULTS INDICATE THAT BOTH ENERGY COSTS AND PEAK ELECTRICAL USE CAN BE SIGNIFICANTLY REDUCED THROUGH OPTIMAL CONTROL OF THE INTRINSIC THERMAL STORAGE WITHIN BUILDING STRUCTURES. HOWEVER, THE COST SAVINGS DEPEND UPON SEVERAL FACTORS, INCLUDING: (1) UTILITY RATE STRUCTURE ; (2) PART-LOAD CHARACTERISTICS OF THE COOLING PLANT AND AIR-HANDLING SYSTEM ; (3) WEATHER ; (4) THE OCCUPANCY SCHEDULE ; AND (5) BUILDING THERMAL CAPACITANCE.
