Model Selection and Verification Approach for Green Remodeling of Non-residential Buildings Using Building Management Information and Energy Simulation

To reduce energy consumption in non-residential buildings, the government has introduced a policy offering loan interest support for green remodeling costs. However, this policy’s effectiveness has been proven ineffective due to its complex and costly building selection process. This study proposes simplifying the selection criteria by targeting buildings with high primary energy consumption of 260 kWh/(㎡ y) or more, small total floor areas of less than 500 ㎡, and older construction built before 2008, for support. Additionally, measures are suggested to provide green remodeling operators with information about financially troubled buildings that received subpar evaluations under the Building Management Act. This aims to encourage green remodeling businesses to consult owners of such buildings on the economic benefits of the interest support system, ultimately promoting the transformation of financially troubled buildings into green remodels. This policy proposal is expected to boost green remodeling in private non-residential buildings.
