Abstract

Existing studies of building exterior materials have focused on the colors or textures of cladding, and in terms of a design planning approach, have focused on the use of the environment and equipment and fire safety topics from an engineering perspective. As a result, little research has been done on performance guidelines for exterior materials, specifically according to the building type. Research into eco-friendly cladding materials is also in the rudimentary stage in a practical sense. In this study, the use of exterior materials over the last ten years in domestic construction was analyzed. The usage status of building exterior materials was evaluated quantitatively by frequency analysis, and its environmental performance is proposed through complex (qualitative + quantitative) analysis. The average value of the exterior material type number used for all analyzed buildings was 2.59. Glass, metal, stone, resin, cement, wood, and clay were used in that order with regard to the usage status. The analysis found that five of the materials satisfied the high efficiency and eco-friendly grading in terms of the four characteristics of an eco-friendly exterior. A list of eight eco-friendly elements was also proposed. The eco-friendly elements and characteristics of the exterior materials were derived to provide basic guidelines for domestic construction companies and design offices.

외장재에 대한 기존의 연구는 디자인 측면에서 계획적인 접근이 많아 외장재의 성능보다 외장재의 색채나 질감 등에 초점을 맞춘 연구가 많았으며 용도에 따른 공학적인 접근에서는 환경과 설비, 화재 구조 등 일반적인 연구 주제들에 국한되어 건물 유형에 적합한 외장재 선정과 성능제시에 관한 연구는 많지 않았다. 물론 최근 환경에 대한 관심이 높아지면서 친환경적인 관점에서 건축물 외장재의 연구가 이루어지고는 있으나 친환경적인 외장재 선택에 대한 실무적인 관점에서의 연구는 초보적인 단계이다. 따라서 본 연구에서는 최근 10여 년간 국내에서 사용된 외장재에 대한 사용 현황을 분석하고 건물용도별 외장재의 특성과 친환경적인 요소를 도출하여 향후 국내 건설업체 및 설계사무소 등이 친환경적이면서 성능이 적합한 외장재를 선택할 수 있도록 기본적인 정보를 제공하고자 하였다. 외장재 사용현황은 정량적인 빈도수 분석, 친환경 성능은 복합적인(정성+정량) 분석을 통하여 이루어 졌다. 조사된 건물의 외장재종류 개수의 평균은 2.59개로 나타났으며 유리, 금속, 석재, 수지, 시멘트, 목재, 점토 순서로 많이 사용되고 있었다. 4개의 친환경 외장재 특성에 의거하여 5종류의 고친환경재료를 선정하였으며 8가지 친환경적인 요소를 제시하였다.
