Abstract :
Urbanization is gradually becoming a worldwide phenomenon since there is a colossal growth in population around the world. There is an emergent demand of housing around the world and hence construction sector is the booming sector all over the world. This accounts for extreme energy consumption and leading to GHG emissions which contribute to phenomenon of global warming.CO2 is the major gas contributing to GHG emissions. Concrete is the vital building material used in construction. The production of concrete is responsible for emission of CO2 gas. Thus, main aim of energy management of buildings is to propose a sustainable approach in conventional design method which can be introduced during conceptual design stage. This paper enumerates the quantification of the CO2 emission of construction material especially concrete. All construction materials endure through various stages right from raw material extraction, transportation, manufacturing till demolition and waste processing. These stages are called system boundary. The system boundary for present study is manufacturing of concrete which is responsible for emission of CO2 gas. Manufacturing of concrete requires energy consumption in many ways.Power sector in the form of electricity is one of the pathways of energy consumption responsible for CO2 emission. The study involves comparative analysis and design of G+4 RCC building with structural components especially slab and columns as variable parameters. Based on the final design, the quantification of CO2 emission for concrete is accomplished. Available data of energy consumption required for manufacturing process of concrete and integration of emission factor with energy consumption leads to quantification of CO2 emission. The conclusion demonstrate that with variation in design of structural components, a considerable amount of quantity of CO2 emission can be controlled, rather than concentrating on design and analysis of low carbon material, which requires lot of time and cost.
