A Study on Energy Consumption and CO<sub>2</sub> Emissions in End-Life Cycle of Residential Buildings

Abstract

In recent years, demolition work in Korea has been rapidly increasing, and accordingly, its environmental impact has become significant, thus requiring quantitative analysis on energy consumption and CO2 emissions generated during demolition work. This study aims to examine energy consumption and CO2 emissions in the end-life cycle of buildings. In this study, inventory analysis was conducted and basic units of energy consumption and CO2 emissions were calculated in accordance with Intergovernmental Panel on Climate Change (IPCC) guidelines published in 1996. Major findings show that 64% of energy consumption and CO2 emissions in buildings’ end-life cycle is generated in the demolition phase, and 36% in the transportation phase.
