Abstract

As a key policy for achieving the goal of reducing GHG in the building sector, Korea has enforced the mandatory certification of zero-energy buildings for new buildings in the public sector from 2020. This study evaluated a policy to achieve Net Zero by identifying the trend of changes in building energy performance according to policy and presenting a methodology to analyze the current performance state of energy technology applied to buildings. The final goal was to help stakeholders apply appropriate energy technologies for new buildings. For this study, data collected on building energy efficiency certification over the last four years have shown a gradual increase in energy performance. In addition, K-means cluster analysis was used to analyze the performance status of energy technologies applied to buildings. The high and low clusters of education and office facilities were used to analyze the comparative group (2016-2020, 2020). As a result, the solar module area in both high and low clusters of education facilities increased by 261.1% and 283.5%. In contrast, the solar module area decreased by both high and low clusters of office facilities. The most passive and active technologies showed an increase in energy performance.

한국은 건물부문 온실가스 감축 목표 달성을 위한 핵심정책으로 2020년부터 공공부문 신축 건축물을 대상으로 제로에너지건축물 인증 의무화를 시행하였다. 이 논문은 궁극적인 Net Zero 에너지건축물 달성하는 데 있어서 정부의 정책에 따른 건축물 에너지성능의 변화 추세를 파악하고, 최근 건축물에 적용된 에너지기술 성능의 변화 추이를 분석하는 방법론을 제시함으로써 궁극적으로는 장기적인 Net Zero를 달성하고자 하는 정책 환경의 변화에서 건축 관련 이해 관계자들이 건축물 유형별로 적절한 에너지기술들을 적용하는데 도움을 주고자 한다. 본 연구를 위해 최근 4년간 건축물 에너지효율등급 예비인증 데이터를 수집하여 건축물의 에너지성능이 상승하는 추세를 확인하였다. 또한, 최근 건축물에 적용된 에너지기술들의 에너지성능 현황을 분석하기 위하여 K-means 군집분석 활용해 교육연구 시설과 업무시설의 High, Low 에너지성능 군집을 통해 비교군(2016년~2020년, 2020년) 설정하여, 분석하였다. 분석 결과 교육연구 시설의 High, Low 군집 모두 태양광 모듈 면적의 증가율이 261.1%, 283.5% 급증하였으며, 업무시설은 High, Low 군집 모두 태양광 모듈 면적이 감소하는 반면에 대부분의 패시브, 액티브 기술의 에너지성능이 증가하는 것으로 분석되었다.
