COMPOSITE ROOFING SECTIONS FOR SUSTAINABLE ENERGY EFFICIENT BUILDINGS

S. Eshwariah, M. Viswanadham

Abstract: The construction industry is the largest economic activity of any nation. More than 60% of counties raw materials, 12% of regular water is being consumed by the buildings. In addition million tonnes of construction and demolition wastes are generated every year. Natural construction materials are no more freely available and materials produced in large scale industries have become more energy intensive. Sustainable building design aims at durability, economy, reducing pollution and environmental degradation. Locally manufactured products are preferred so that the collective material environment of locality remain a constant and moreover the fuel for transporting the material is saved.A comparative study is made on an alternative composite roofing section of shabad stone+ PCC over RC rafters to a conventional RCC roofing for a single room tenement house. Study is made for strength, stiffness, energy consumption, thermal performance and cost. It is found the alternate section has satisfied the requirements of strength and stiffness and performed well in energy consumption, thermal performance and the cost compared to RCC.

Keywords: sustainable construction, composite roofing, shabad stone roofing, embodied energy, thermal comfort, affordable housing construction.
