Abstract
The solar reflectance and absorbance of the roof surface are two significant factors affecting the thermal performance of non-conditioning buildings. Based on the qualitative analysis, the cool roof (color paint) effect analyzed in terms of indoor temperature. The maximum heat gain entered in the buildings during summer leads to higher energy consumption throughout the summer. Eight composite roof structures with cool paints layer and one without cool paint layer as the base case analyzed for the summer months of April–July. Fourier admittance method used to evaluate hourly floating temperature for roofs treated with cool paints. A simulation study carried out to obtain optimal roof structure for hot–dry climate, Jodhpur and roof structure (RS-6) with concrete, mortar, and cool coating paint combinations found most suitable in terms of minimum variation of indoor temperature. The simulation result indicates that all roof structures with cool roof performed better than roofs without cool roof.
