Abstract

Exterior Insulation and Finishing System(EIFS) is recognized as a promising alternative for energy reduction as energy reduction ratio of apartment is to be increased from 40% to 60% in 2017. However, EIFS is not actively applied to apartment because additional construction costs and duration are required for the current existing construction method of EIFS. Therefore, this study proposes a conceptual framework for concurrent construction method of EIFS which can reduce construction costs and duration by working sequentially from frame work to exterior insulation finishing work, and then verify the method's feasibility by analyzing a case study. It has been proven from the analysis that concurrent construction method of EIFS reduces 6.7% of construction duration and 13% of construction costs compared with the conventional exiting method. The proposed method is expected to contribute to invigorated application of EIFS to apartment.

공동주택의 에너지 의무 절감률이 현재 40%에서 2017년에는 60%까지 단계적으로 상향 조정되면서 에너지 절감을 위해 외단열 공법이 주목받고 있다. 그러나 기존 외단열 공법은 내단열 공법에 비해 추가되는 공사비와 공사기간으로 인해 활성화가 미흡한 실정이다. 따라서 본 연구는 외단열공사와 골조공사를 연속적으로 시공함으로서 공사기간을 단축하고 공사비를 절감할 수 있는 외단열 적층시공 공법의 개념모델을 개발하고 사례적용을 통해 공법의 타당성을 검증하였다. 연구결과 외단열 적층시공 공법은 기존의 외단열 공법에 비해 6.7%의 공기절감 효과와 13%의 외단열 공사비 절감효과가 있는 것으로 나타났다. 본 연구의 결과인 적층시공 공법은 외단열 공법적용의 저해요소를 해결하여 향후 외단열 공법 활성화에 기여할 것으로 기대된다.
