“Embodied - Carbon Emission from Building In Overall Life Cycle - A case study of Kathmandu”

Abstract

Most of the studies haven often focused on the mitigating measures of operation carbon with little focus on the embodied carbon emission. To achieve the embodied carbon emission from the buildings of Kathmandu district, a process-based approach was adopted to estimate the embodied carbon from the building sector of Kathmandu district in overall life cycle. The overall result of the study shows the total embodied carbon emission from the building sector in the overall life cycle was 1444.86 Mt. While using the alternative materials AAC block, hollow cement concrete block and AAC block with aluminium openings in the same building reduces the total emission by 4.7%, 3.37% and 1.93% respectively. The research have focused on the construction phase including only the civil raw materials rather than the sanitary and electrical fixtures. So, detail analysis considering the electrical and sanitary fixtures and other phases like operation and maintenance and demolition should be considered in future study.
