탄소중립을 위한 공공건축물 그린리모델링 에너지 절감 효과 분석 : 국공립 어린이집, 보건소, 공공의료시설을 중심으로

Abstract

Purpose: As the need for environmental protection was further emphasized after the outbreak of COVID-19, Korea submitted the “2050 Long-term low greenhouse gas Emission Development Strategies” and the “2030 Nationally Determined Contribution” to the UN in October 2021. Accordingly, the greenhouse gas reduction target in the building sector has also been greatly raised, and among them, green remodeling of existing buildings is mainly focused on building energy along with zero energy. To this end, the government adopted the green remodeling project for public buildings as the key project of building NetZero and Korea NewDeal. This is a green remodeling of existing public buildings with a focus on public buildings mainly used by children and the elderly who are vulnerable to infectious diseases. Method: This study analyzes the construction method applied to reduce carbon emissions through energy design consulting, focusing on 1,065 buildings that are the target of the support project. And, the energy saving effect of the design consulting is analyzed, and the development direction of the public building green remodeling project is suggested through this analysis. Results: As a result of regional average energy saving rate analysis through green remodeling, the overall average energy saving rate was analyzed to be 36.8%. By use, the health center showed the highest energy saving rate. In the future, green remodeling of public buildings needs to secure a substantial business plan and quality through business planning and energy design that reflects the characteristics of the building, and it is necessary to expand support in consideration of the urgency and popularity of the project.
