A CUMULATIVE ENERGY ASSESSMENT OF MULTI-STORIED RESIDENTIAL BUILDING IN COMPOSITE CLIMATE

Abstract

The construction sector consumes a lot of resources for building construction. According to the International Energy Agency (IEA), in 2020, it is estimated that the building operation and construction industry account for 38% of global carbon dioxide emissions related to energy. Due to the growth in the population there is a constant demand of housing in India. Thus, the energy consumption associated with the residential sector is a major point of concern. This dissertation aims to present a study on the cumulative energy assessment of a multi-storied residential building during its development and operation. The scope is restricted to an apartment building in composite climate. The analysis focuses on the variation of embodied and operational energy consumption due to the use of alternative building materials. The study revealed that the embodied energy is reduced up to 59.32 % due to the use of alternative materials and the annual operational energy is reduced up to 18%. The study also focuses on the Embodied Energy and Operational Energy Intensity per floor area for various combinations which gives the Cumulative Energy Intensity for those combinations as the end result.
