摘要
在臺灣,建築能耗約占全國總能耗的30%,而外殼建材影響建築物耗能所占的比例相當大,因此發展高性能外殼建材已成為世界各國相關產業的重要課題之一。有鑑於氣凝膠的低熱傳導(隔熱性能)、高透光、低折射率以及防火等優越性能,若能依照建築物外殼主要三大構造:屋頂、外牆與窗戶,以氣凝膠為基礎材料開發此三大構造的節能建材,將會提升建築外殼的節能效益。本研究團隊目前已利用階段式常溫乾燥技術加上疏水性改性,開發出200 g批次生產量之氣凝膠粉體。透過紅外光光譜儀(FTIR)官能基分析,掃描式電子顯微鏡(SEM)結構分析,BET比表面積及接觸角量測均顯示,本研究所開發之產品為典型奈米二氧化矽氣凝膠材料,不僅性能與國際標竿產品不相上下,更具低成本、危險性低之優點。再者,本文探討現行市場上二氧化矽氣凝膠應用在玻璃建材與隔熱毯兩部分之產品特性,建議氣凝膠未來應用在隔熱建材之方向。

The environmental footprint of the building sector includes 30% of energy use. The building sector is responsible for more than one third of energy-related GHG (Greenhouse gas) emissions and, in most countries, is the largest emissions source. As well known, energy saving and carbon oxide reduction should have Key Performance Index but not slogans only. Therefore, the integration of the various energy saving technologies used in Taiwan and other countries is applied for developing the innovative building material with high thermal-insulated performance in this study in order to enhance the capability international competition. In this study, a pilot scale process of a green energy material-Si based aerogel has been developed. The future research issues are also proposed for designing a glazing system with optimal visible light transmittance, energy-efficient performance and building materials with aerogel, in order to meet the requirement for architectural application. The technologies developed in this integrated projects will be very helpful for Taiwan future energy saving, in particular in building energy performance.
