에너지 성능 향상을 위한 공동주택 외단열 설계 연구

The IIS(Internal Insulation System) is typically applied in most Korean apartment buildings. Consequently, there exist many thermal bridges at the wall-slab and wall-wall joints in the envelope. It is expected that the EIFS(External Insulation and Finish System) is the solution to this problem. The aim of this study is to suggest external insulation design schemes suitable for Korean apartment buildings in order to facilitate the application of EIFS. After making 23 alternatives for 9 regions, each alternative's relative insulation performance and constructability were then evaluated. As results, 9 design schemes for 9 regions were suggested.
