ANALYSIS OF OVERALL THERMAL TRANSFER VALUE (OTTV) ENERGY CONSERVATION STANDARD FOR SINGAPORE OFFICE BUILDINGS.

Author(s) : TURIEL I., CURTIS R., LEVINE M. D.

Summary

THE PRESENT SINGAPORE OTTV STANDARDREQUIRES THAT AIR CONDITIONED BUILDINGS HAVE AN OTTV LESS THAN 45 W/M2. THE OTTV CONCEPT TAKES INTO ACCOUNT THE HEAT GAINS THROUGH THE WALLS OF A BUILDING. AN ANALYSIS INDICATES THAT THE TERM FOR RADIATION THROUGH WINDOWS, UNDERSTATES THE CONTRIBUTION OF THIS TYPE OF HEAT TRANSFER, AND THE HEAT CONDUCTION TERMS OVERPREDICT CONDUCTIVE HEAT TRANSFER. THUS, THE STANDARD UNDERESTIMATES THE ENERGY SAVINGS THAT CAN BE ACHIEVED. THE AUTHORS RECOMMEND THAT SINGAPORE REPLACE THE EXISTING SINGAPORE OTTV FORMULATION WITH ONLY ONE TERM, A SOLAR GAIN TERM. IN LOCATIONS WHERE HEATING IS NOT REQUIRED (HONOLULU OR MIAMI), A COMPARABLE ANALYSIS MAY RESULT IN SIMILAR CONCLUSIONS.
