Abstract
본 연구는 공공발주 모듈러 공동주택의 제로에너지건축물 인증등급 달성을 위한 기술요소와 개선요소 조합별 1차 에너지 소요량 및 증분비용을 분석하였다. 6개의 개선요소를 선정하여 3단계로 성능 수준을 가정하였다. 패시브 요소와 액티브 요소를 개선하는 것으로는 ZEB 기준을 만족하지 못하고, PV가 옥상면적의 40% 이상 설치된 경우 ZEB 5등급을 만족하는 것으로 나타났다. 제로에너지건축물 인증등급 달성을 위한 개선요소 조합을 제안하기 위해 우선순위에 따라 개선요소의 비용성능지수를 분석하여 조합하였다. 조합 결과 단위면적당 증분비용은 ZEB 5등급 62,392원, ZEB 4등급 96,380원, ZEB 3등급 120,389원으로 분석되었다. 본 연구는 제로에너지 건축물과 모듈러 공동주택 도입 당시의 에너지 성능 및 증분비용을 분석하였다는 점에서 의미가 있다.
This study examined the primary energy requirements and additional costs associated with different combinations of technology and improvement factors to achieve a zero-energy building (ZEB) grade for public order modular apartment houses. The analysis considered three stages of performance for six improvement factors. The findings revealed that individual enhancements to passive and active elements did not meet ZEB criteria. However, installing photovoltaic (PV) systems covering at least 40% of the rooftop area satisfied the ZEB 5th grade. To propose an effective combination of improvement factors for ZEB certification, the cost performance index was analyzed, and factors were prioritized accordingly. The analysis indicated incremental costs per unit area of 62,392 won for ZEB 5th grade, 96,380 won for ZEB 4th grade, and 120,389 won for ZEB 3rd grade. This study holds significance as it provides insights into energy performance and incremental costs during the introduction of zero-energy buildings and modular apartment houses. © 2023 Architectural Institute of Korea.
