Abstract

The purpose of this study is to provide the basic data on the environmental impact increase and decrease according to the envelopment retrofit by each part of green remodeling. The difference of the environmental impact occurred during the remaining life of the green remodeling and the non-green remodeling is compared. The study is carried out with case study using life cycle assessment(LCA) method. Based on the goal, functional units, system boundaries, and notation of results are proposed. The system boundary for the environmental impact evaluation of green remodeled buildings is proposed and 6 major environmental impacts are shown as results. In addition, the environmental impacts of the envelopment improvement conditions are analyzed by case studies. From the green remodeling process stage, the change of environmental impact is evaluated by life cycle. As a result of the case evaluation, the GWP and AP decreased due to the energy saving of the green remodeling. However, ADP, EP, ODP, and POCP have shown increase.
