SHORT-TERM ENERGY MONITORING IN A LARGE COMMERCIAL BUILDING.

Author(s) : BURCH J.

Summary

A DYNAMIC SIMULATION MODEL OF A BUILDING RENORMALIZED FROM SHORT-TERM TEST DATA CAN BE USED TO ANSWER A LARGE VARIETY OF QUESTIONS ABOUT THE THERMAL PERFORMANCE OF THE BUILDING, SUCH AS COMMISSIONING, LOAD CONTROL, AND DIAGNOSTICS. A SHORT-TERM TEST METHOD WAS APPLIED TO A LARGE OFFICE BUILDING TO TEST THE KEY STEPS OF THE METHOD IN A NON-RESIDENTIAL BUILDING. THE RENORMALIZED MODEL PROVIDED A GOOD FIT TO THE TEST DATA AND EXPLAINED THE BUILDING PERFORMANCE IN TERMS OF PHYSICALLY SIGNIFICANT HEAT FLOWS. THE MOST SIGNIFICANT BUILDING-SPECIFIC RESULT IS THAT THE BUILDING LOSS COEFFICIENT IS 1.9 TIMES THE DESIGN VALUE, EXPLAINING IN PART WHY HISTORICAL CONSUMPTION HAS BEEN SIGNIFICANTLY LARGER THAN THE DESIGN PREDICTION.
