國中小校舍木質複合外牆整建木質牆板使用率灰色決策研究

The Grey Decision-Making of Wooden Wall Panels Usage Ratio for the Wooden Composed Exterior Walls Refurbishment in Junior High Schools and Elementary Schools

台灣國中小學老舊校舍外牆面臨安全、性能等課題，亟待改善。本文基於建築系統構法之創新觀點，採用木質複合構法整建，結合木質牆面與異種材料牆面，以提昇外牆品質、減少環境負荷及延長生命週期。外牆整建類型，包括：走廊邊外牆正面、走廊邊正面護欄、外牆背面以及外牆側面。本研究主要應用灰色系統理論，建構木質複合外牆整建之決策模式。決策評估係以分析因子：外牆性能評價因素與外牆材料整建要素，整合建立關係矩陣，進行問卷調查、分析評比。研究目的在於分析木質牆板、磁磚、洗石子、水泥砂漿粉刷等外牆材料，其整建要素之重要度評比，以做為訂定木質牆板使用率評估指標之參考。研究成果係木質複合外牆整建，木質牆板與異種材料牆面複合比例之參考基準，並提供國中小學校舍外牆整建決策之參考及運用，以提升永續校園品質。

The exterior wall of old buildings in the junior high schools and elementary schools in Taiwan are facing the issues of safety and performance which need to be improved. Based on the viewpoint of innovation, this paper adopted composite wood construction systems to refurbish the exterior wall, in order to promote quality, reduce environment burden, and lengthen the longevity of exterior walls. The types of exterior walls refurbishment include: facade, railing, back, and side. In this project, we mainly adopted the grey system theory to establish the decision-making model. Through analysis of data acquired from a questionnaire survey, we then established the correlation matrix between performance factors and refurbishment factors, to conduct the decision-making of exterior walls refurbishment. The research purpose is to analyze the importance rating of exterior walls refurbishment materials, such as: wooden wall panel, tile, stucco washing finish, and cement mortar, to serve as the reference for wooden wall panels usage ratio. The results acquired are employed as references of wooden wall panels usage ratio for the wooden composed exterior walls refurbishment. Furthermore, the results are served as the reference for evaluating on the refurbishment projects, to promote the quality of sustainable school.
