摘要：Recently, apart from the energy saving of new buildings, various carbon-centered environmental policies for climate change were implemented to improve the energy performance of existing buildings, actively promoting green remodeling businesses. This study proposed a classification system for green remodeling envelope systems to select the applicable representative method and input material for the green remodeling of apartment housing. The system boundaries were divided into the material production stage and construction waste processing stage, and the classification system of the envelope system was implemented for applicable green remodeling. A database for the environmental, economic, and energy performances of the classification system was created. Moreover, a green remodeling evaluation sheet system was proposed. According to our results, the economic, energy, and environmental performances of the proposed combinations of the insulation systems were higher than those of the reference combination by 30%, 10%, and 30%, respectively. Regarding the window systems, the economic and energy performances of the proposed input material combinations were higher than those of the reference combination by 22% and 10%, respectively. Additionally, the energy performance of the proposed input material combinations was higher than that of the reference combination by 8~64%.
