Development of a BIM-based Carbon Dioxide Emission Estimation System -Focus on an Apartment in Korea

Abstract

Recently, a goal was set globally to reduce the Carbon Dioxide (CO2) emission at national levels by 30 % in comparison to the Business As Usual (BAU) pursuant to the United Nations Framework Convention on Climate Change. As construction industry accounts for as high as 40 % of the CO2 emission by the entire industrial sector in Korea, efforts toward reducing emissions from the construction industry are essential. Buildings are mainly responsible for CO2 emissions, and, to reduce the CO2 emitted from the buildings, a fast and accurate calculation method is required to be introduced in the architectural design phase. If the standardized data based on Building Information Modelling (BIM) is utilized, CO2 emissions can be calculated quickly and accurately during the design phase. However, it is difficult for the designers who lack the knowledge regarding CO2 emissions to reduce and manage such emission during the planning and design phases of buildings by estimating the quantities of various materials and the corresponding CO2 emissions. Accordingly, the objective of this study is to develop a BIM-based CO2 emission estimation system for a rapid and objective analysis and verification of CO2 emissions
