Heat transfer characterization of test rooms with six different roofs

Abstract

Six test rooms each with different roof type (RCC roof; galvanized iron sheet roof; lawn over RCC roof; wet-sand bed over RCC roof; clay tile roof and thatched roof) under summer weather conditions are studied to analyze and quantify the role of roof element in reducing solar gain. The study also addresses the effects of roofing element on the test room temperatures. Results have shown that, lawn over the RCC roof could be the best choice among the considered. On the other hand, clay tile roof and thatched roof are found to be better than RCC roof as far as heat gain is considered. It is also observed that, clay tile roof providing better breathing effects as compared to thatched roof.
