ENERGY CONSUMPTION OF BUILDING ELEMENTS USING SUSTAINABLE CONSTRUCTION MATERIALS

Abstract Energy consumption of the buildings is high compared to the other economic sectors like agricultural and transportation fields. Due to climatic changes also, the building consumes more energy and these results in increasing the carbon-di-oxide emission in the environment. As a consequence, the carbon di- oxide emission into the environment is high in the range of 30-45% in overall carbon dioxide emission. Increasing the energy efficiency of the building is the key mitigation strategies to reduce the carbon di-oxide emission. In this work, two different type of construction material are used for analyzing energy consumptions of the building using Design Builder software. For the existing buildings the normal brick wall was insulated by polystyrene and the roof was insulated by fibre wool in these the energy loss is reduced by 77%. In new buildings the normal brick wall builds as cavity wall with polystyrene insulation and roof was coated with fibre wool and by this the energy loss is reduced by 80%.
