健康綠建材揮發性有機化合物逸散量對室內空氣品質影響之研究

Quantifying the Effect of VOC Emissions on Indoor Air Quality for Green Building Materials in Taiwan

建築室內裝修使用之材料常含有揮發性有機化合物，對室內空氣品質及人體健康有許多潛在影響。目前健康綠建材標章已針對室內建材之健康性能，以低揮發性有機化合物及甲醛之逸散速率為指標進行評估。因此，本研究之目的係為了解室內空氣品質與室內裝修建材逸散量之關聯性，並應用簡化質量平衡模式比較不同健康綠建材使用量對室內空氣品質產生之影響。模擬結果發現室內裝修量越高對室內空氣品質影響越大，且室內環境之裝修量負荷率（Loading factor） 須小於0.4 ，室內環境之TVOC 、甲醛濃度才會在健康標準範圍內。而影響室內揮發性有機逸散物濃度的關鍵因素，除裝修材料使用量外，VOC 逸散速率及室內換氣率亦是重要因素，因此，未來健康室內空氣品質設計策略，可依該空間之換氣率進行裝修量的控制，或多採用健康綠建材以進行源頭控制。

Inappropriate use of the artificial chemical building materials, the potential hazards and health risk of indoor air quality (IAQ) were occurred. Low emissions of Volatile Organic Compounds (VOCs) and Formaldehyde were used to evaluate the healthy performance of green building materials. The purpose of this study is to understand the relationship between indoor air quality and decoration quantity, and to compare the effect of different usage of green building materials on indoor air quality using the simplified mass balance model. The results showed that the indoor environment will lead to better healthy, if the value of loading factor of the decoration can be controlled more less 0.4. In addition, the important factors associated with VOCs concentration on indoor air quality are the decoration quantity, emission rate of building materials and ventilation rate. Therefore, in design phase, the ventilation rate can be used to control the decoration quantity, and the adopted green building materials to control emission sources.
