| Abstract |
In this study, we analyzed the existing buildings and green remodeling activation status in Korea. We also analyzed the satisfaction of green remodeling and heating energy saving effect on residential buildings. Many residential buildings have been built for ten to thirty years after completion. Apartment type buildings have been the main building type, and green remodeling buildings have also appeared accordingly. Green remodeling buildings are mainly distributed in capital metropolitan cities, unlike aged buildings are mainly distributed regional area. As a result of the survey on the satisfaction of the green remodeling, many respondents were satisfied with the improvement of the indoor environment after the green remodeling. In particular, satisfaction levels were high regarding blocking outside noise and blocking chilly air or heat. The energy saving effect on gas for heating was a reduction of about 14% on average compared to before the green remodeling, and the confidence interval range was analyzed as 8% ~ 20%. |
