Numerical Analysis of Thermal Performance of RCC Roof

The ever alarming cost of energy in buildings enforces a statuary demand of energy conservation passive design techniques in buildings. Modern buildings reveal inadequate thermal performance and require mechanical devices to bring thermal comfort. Hence, it is necessary to know the thermal performance of the RCC roof structure, which is quite commonly available. This paper concentrates on developing a numerical model of a Reinforced Concrete (RCC) roof for analyzing its thermal performance. Numerical Simulations have been performed for unsteady conditions with time-varying solar heat flux along with grid independence tests for accurate analysis.
