주택모델의 벽체단열형식별 온실가스 전과정평가

Abstract

Buildings are high consumers of energy and therefore have a significant impact on the global environment. The aim of this study is to determine ways to reduce the Green House Gases(GHG) given off by the heating energies of model building and the embodied energy of Insulation with in walls. Compared with the apartment and a housing, becausea housing surrounded 4 side of air, energy loss of the housing is more than the apartment's. The tool of this study is Energy Plus program and IPCC's Life Cycle Assessment(LCA) method. According to this study, an GHG emissions of the Exterior Insulation-THK 400mm Type is showed approximately 12% reduction in GHG for heating in this housing model lower than the type of non Insulation with in walls. But when the Embodied energy is included, The Exterior Insulation-THK 50mm Type's GHG emissions is approximately 10% lower than non insulation structure in the LCA including Embodied energies. Finally, this paper presented a method of comprehensive environmental load which is related to the passive design.
