패시브디자인을 위한 오픈조인트 커튼월 외단열시스템 개발

Abstract

Purpose : For passive construction, highly efficient high thermal insulation sheathing is essential and sectional details without thermal bridge should be implemented. However, it can not be secured by the conventional method of constructing a dry exterior system. Therefore the purpose of this study is to develop an open joint curtain wall insulation system that can realize energy efficient panel exterior finishing by suppressing thermal bridge in anchoring unit. Method: The method of study is as follows. First, the types and characteristics of the external insulation methods are examined. Secondly, the target performance is set, and the structural materials are selected and simulated. Third, the designed specimen of the open joint curtain wall external insulation system is manufactured, installed and tested. Finally, we analyze the performance test results and propose a commercialization method. Result: To develop an open joint curtain wall outer insulation system, Test specimens designed by performance simulation by selecting structural members were prepared and tested. As a result, both the thermal transmittance and the condensation and the outdoor performance test showed that the target performance index was satisfied. This is an economical and eco-friendly construction method by shortening construction period and cost reduction. In order to commercialize, design improvement and quality control system that can make precise production and construction should be done.
