The world is facing climate change due to numerous human activities and industrialization, which greatly damages the ecosystem, food security, water supply, and health systems. To this end, the ¡®2050 Carbon Neutral Scenario¡¯ was established for each industry, transportation, and building sector, and performance improvement of existing buildings(a.k.a. Green Remodeling) is suggested as an essential energy efficiency improvement strategy to reduce energy demand and greenhouse gas. The Ministry of Land, Infrastructure, and Transport has been conducting a "Private Interest Support Project" to support private finance loans for high initial performance improvement construction costs, including installation of high-efficiency cooling and heating systems, from 2013 to the present. Therefore, this study aims to quantitatively evaluate the economic feasibility of each type of private building that has completed green remodeling, it is necessary to recognize the economic problems and profitability of private buildings. As a result of analyzing the cost benefits of green remodeling by building type, the B/C ratio was estimated for single-family housings (1.162), multi-family housings (0.384), and non-residential buildings (0.7) respectively. As an implication, it is necessary to gradually make green remodeling mandatory for aging buildings in the private sector according to the current situation, such as gradually realizing mandatory in the public. The change in policies can increase accessibility to the private sector and reduce the financial burden by easing the complex procedures and loan interest burdens that are currently raised as the main problems by builders or private companies. |
