소규모 주택의 그린 리모델링 도입 타당성 분석

Abstract

Purpose: Recently, various technologies and policies have been introduced in building to reduce the energy demand and to provide a comfort and beneficial residential environment. However, various policies to reduce the heating/cooling load and to improve energy efficiency are mainly applied to new buildings and public institutions. Accordingly, the government is promoting a green-remodeling policy for improving the energy efficiency and performance of aging buildings. In this study, the energy performance evaluation and feasibility analysis on green-remodeling of the small-scale housing was conducted. Method: In this study, in order to quantitatively analyze the energy consumption according to the application of green-remodeling design factors, ECO2 program that used for energy evaluation was utilized. Furthermore, feasibility analysis was conducted based on the green-remodeling technologies and results of the energy consumption. Result: In order to meet the minimum requirements for green remodeling and receive interest support, the insulation performance conditions differed by region. When the renewable system was installed, the results of economic analysis were different depending on the specific period. Considering the support fund of renewable energy provided by the government, the payback period could be shortened from 4 to 8 years.
