전과정평가에 기반한 서울시 아파트의 이산화탄소 배출량분석

Abstract

Apartment housings are the most representative type of residence in Korea and thought to be significant sources of energy consumption and CO2 emissions. But quantitative assessments of CO2 emissions during the life cycle of apartment housings are still quite rare. Therefore, this study presents a life cycle assessment of apartment housings in Seoul, Korea. In this study, apartment housings were classified into ten types by their building types, heating systems, and heating fuels. Analysis was conducted to analyze the amount of CO2 emissions of each type during the construction phase, operation phase, and dissolution/disposal phase. The results indicate that the average amount of CO2 emissions of apartment housings is 2208.40kg-CO2/㎡ for a 40-year service life, and that most targeted measures to reduce such emissions should be in the operation phase. The results also show that BBA, CAA, and BAA types are consuming more energy and emitting more CO2 than other types. Apartment housings in Jongro-gu, Dongjak-gu, Gangdong-gu and Guro-gu are more intensive in terms of energy consumption and CO2 emissions than other districts. The results of the study can be useful to the urban planning and architectural fields in efforts to reduce the amount of CO2 emissions.
