Experimental and numerical analysis of heat transfer across polyvinyl chloride pipe embedded weatherproof course laid reinforced cement concrete roofs

Abstract

Usually heat penetrates into a building envelope predominantly because of convection conduction and thermal radiation through the modes of roof walls floor and windows The heat transmission through the roof is much higher than that of the other modes because the intensity of heat from solar radiation that streams through a roof to the attic space causes discomfort for inhabitants and leads to cooling the zone with cooling appliances Especially buildings consume 20 40 of total electrical energy in which significant percentage of energy is consumed by air conditioners as they cool the inhabitants space Energy conservation has become the need of the hour due to depleting reserves of fossil fuel reserves and severe environmental degradation of fossil fuel usage A study of heat transmission across the building roof has been taken with a view to conserve energy newline A through literature survey related to heat transfer across various elements of building and ways to reduce it has been carried out and the problem for the present study is chosen A study of heat transfer across five roof structures viz bare RCC roof RCC roof Weatherproof course laid RCC roof WPC roof Galvanized Iron pipe embedded WPC laid RCC roof GI Roof Hollow Slab WPC laid RCC roof HS roof and Polyvinyl Chloridepipe embedded WPC laid RCC roof PVC roof are taken for the research newline newline
