Abstract
Thailand is in a tropical region where the global solar radiation often reaches 1000W/m<sup>2</sup> or above
with high ambient temperatures and humidity throughout the year. As the sun travels overhead throughout the daytime, heat gain from the roof is significantly pronounced, which consumes intensive amounts of energy from buildings' air conditioning systems. This research focuses on
insulated roofs as an energy efficiency measure for stand-alone convenience stores. The resistancecapacitance
(RC) model was developed for determining the heat amount from different roof configurations. The model is validated using the measured results: one set from a laboratory chamber and the other set from a selected real store. Based on the annual local weather data, the performance
of the insulated roofs is simulated and evaluated against the existing roof. It is evident that the insulated roof can reduce heat gain by 53-68% as compared to the non-insulated roof. The financial analysis also indicates that the insulated roof offers better cost-effectiveness in terms of life cycle cost.
