仿生沐霧機制之建築外殼集水構件之探討

生物對於環境變化擁有演化優勢的調適能力，非洲納米比沙漠甲蟲即為於嚴苛環境中利用沐霧機制取得空氣中水資源之特例。過去五十年來，重要的霧收集案例多以獨立之平面網面裝置為主，若結合建築主體應用複層模式於建築外殼導入仿生沐霧機制，蒐集空氣中之水分，應有助於解決部分水資源匱乏之問題。本研究以「誘導式結構」為操作方法，針對甲蟲仿生集水、空氣集水與建築外殼相關議題探討，歸納整合提出17項建築複層外殼空氣集水構件設計原則，其中10項適用集水構件主體，7項屬基地環境評估範疇，並仿臺灣高山高濕多霧環境進行建築外殼集水實驗驗證，考量建築外牆總厚度空氣層模組以10、15、20㎝模組為研究試體，結果顯示複層建築外殼空氣層以20公分厚度者最佳，據此以提供未來水資源開發再生及永續建築外殼設計的參考與建議。

Biological evolution has the advantage of adaptability on environmental changes. An exception case, Africa Namib Desert beetle achieved fog water resources harvesting by fog-basking mechanism in harsh environments. Over the past fifty years, fog collectors mostly important cases are the independent unit form with a flat mesh, if combined with the main building and applied double-skin model import bionic fog-basking mechanism in the building envelope, it could solve part of the problem of water scarcity. This paper attempts to study beetles water catchment mechanism, air water catchment and building envelope investigate related issues with the “Heuristic Structure manipulation model” research methods, and reviewed a variety of research papers and proposes 17 principles. 10 principles belong to the catchment units and 7 are belong to the site assessment. Further imitation humid and foggy environment in Taiwan mountains, experimental verification building envelope components water catchment effect, experiment module consider building envelope thickness, air layer set to 10,15,20 cm. The experimental results show that multi-layer shell air layer thickness of 20 cm were the best. Accordingly to provide water resources development of renewable and sustainable architecture enclosure design references and recomm endations in the future.
