摘要：

To achieve carbon emission reduction target (CERT) by 2030 and carbon-neutrality in 2050, it is impor-tant to actively reduce the emission gap in the private building sector. However, the ongoing COVID-19 pandemic and the Russian-Ukraine war are threatening the green remodeling policy (GRP) worldwide. Therefore, this study analyzed energy consumption savings, GHG emission reduction, and net present value when applying green remodeling to a private building to predict whether or not the current GRP could achieve 2030 CERT and 2050 carbon-neutrality. The main findings are as follows. First, yearly elec-tricity and gas consumption of 84.97 m2 type households can be reduced by 6.19% and 15.58% through green remodeling. Second, based on the energy saving, yearly GHG emission can be reduced about 0.34tCO2eq. Third, the economic feasibility of green remodeling cannot be achieved via the current policy, and NPV17 decreases up to USD-51,485 depending on the credit loan interest rate and the green remod-eling interest subsidy program. In other words, it is difficult to reach 2030 CERT and 2050 carbon -neutrality via the current policy. Therefore, the South Korean government is required to reorganize finan-cial policies, establish active systems, increase public awareness of the policy, and improve energy effi-ciency technology.(c) 2023 Elsevier B.V.
