良好室內空氣品質第一道防線在建築外殼,本研究探討如何在規畫初期從了解外部環境、建築的音、光、空氣、溫熱環境設計,再結合應用設計手法為室內空氣品質把關,達到「源頭管理」目標;主要為室內裝修選材控制,如天花板材不含甲醛、抗菌抗裂縫之玻纖強化石膏板材的應用、石材評選前期之氡氣量測、木皮熱壓板材的穩定性及環保天然塗料,規劃後期並檢核其性能,本研究結論均符合EEWH-BC/室內環境評估表的性能基準。 另探討工程後期之工事行為,實場量測IAQ於冬末春初,室內平均溫、濕度均於我國建議值內,證實外殼之性能檢討可有效調控室內溫、濕度;健身房現場實測可知空調開啟其CO2、甲醛,其2h平均值較常溫低1.3倍,故將常溫、空調啟動,及施工後期收尾、家具進場等狀態之量測值作一分析比對,證實量測過程中現場修補噴塗行為、人員走動、窗簾測試等造成量測過程中PM10、PM2.5數值分別攀升3倍及8倍,而使用電弧焊接器具使CO值超出1.5倍,甚至影響O3,這些起因皆為「行為模式」、「採用工具」而起。 前期良好的規劃亦須落實於工區,本研究量測結果驗證除了源頭管理外,材料落實、工程進度安排更是影響IAQ的要因。
The first step to control indoor air quality lies in the outer layer of a structure. This study aims to discuss how to control air quality by applying various design methods, along with having a thorough understanding of the surroundings, design of sound, lights, air and heating system at the first stage of planning, in order to achieve the goal of “Source Management”. This process mainly begins from the stage of selecting decorative materials, such as formaldehyde–free panels for ceiling use, anti-bacteria/anti-crack GRG (Glassfiber Reinforced Gypsum), stones that have been measured for radon, heat-pressed wooden panels that have been checked for stability and eco-friendly natural paint. They all fit in the standard of EEWH-BC. In the latter part of the study, focus is given to the final phases of construction. Measurements of IAQ were conducted in the late winter or the beginning of spring. The average indoor temperature and humidity lie in the acceptable range suggested by the Taiwanese Government. This fact has verified that the control of building materials is can be conducted in order to manage the changes of indoor temperature and humidity. From measurements taken in a gym, it was detected that the two-hour mean value of Rn and CO2 was 1.3 times smaller than regular temperature after the air conditioner is turned on. Proper planning should also be adopted in the construction sites. Besides effective management right from the beginning stage, selection of building materials and proper arrangement of construction schedule are also important.
