520			_aEnd use Energy of modem commercial buildings is significantly high. Due to lack of energy efficient envelopes of buildings, a large amount of energy is wasted. The understanding of thermal interaction in an air-conditioned building have become a necessity in the aspect of providing comfort as well as for rational use of energy. The most significant cause of high-energy consumption in air-conditioned building in tropical countries is heat transfer through the building envelope. Obviously, the better a building is insulated, the smaller will be tht! heat gain and losses through the structural elements. The high ambient temperature and solar radiation are the main driving forces for the heat transfer through the building envelope in air-conditioned buildings. But such transfer is modulated by the fabric of the envelope components attributed by their thermal properties. Both the driving forces for the heat transfer and the building usage are dynamic processes. It has been proved that the best way to regulate the thermal performances of building envelope for energy conservation is developing the building energy performance standards for buildings envelope for particular climatic area. A well-developed computer program; DOE-2, was utilized as the main research tool. Using the simulation program a model has been developed to represent the energy performance of the buildings category for the study of standards development. The OTTV formulation comprises parameter terms relating to the driving forces, the thermal properties of the building fabric, and the usage schedule of the building. Monthly parameter values ofOTTV formulation and the monthly OTTV values are developed and assessed. Development and assessment of steady-state indicators of cooling requirement for commercial buildings in Sri Lanka are also worked out. Cooling-degree hour, dry-bulb temperature and enthalpy of ambient air are all shown to be good indicators, but cooling degree hour is practically more significant.
