台灣的高溫高濕氣候型態容易導致生物性污染,調濕建材的使用可有效抑制室內高濕度的出現頻率,提升室內空氣品質及居住者健康。為了更有效確認調濕設計對黴菌滋生的控制,本研究以側柏為研究對象,首先以實驗求得材料熱濕物性,作為數值模擬參數。接著採用EnergyPlus軟體中的有效滲透深度法進行空間熱濕環境模擬。最後利用黴菌發芽預測模型,評估搭配不同換氣策略對降低生物性污染風險的效果。研究結果發現,室內建材側柏搭配換氣策略可有效緩和室內濕氣變動量,降低室內生物性污染產生的風險,以夏季(7月份)搭配強制換氣策略12ACH,其可將黴菌發芽群組I之發生率降低94%,呈現最佳調濕效能。
Taiwan has a climate with a high temperature and humidity, which leads to high indoor moisture that causes biological pollutants. Moisture buffering materials are considered an efficient method for controlling the high indoor moisture. In this study, the hygroscopic characters of Western Red Cedar are investigated as parameters for numerical simulation. Additionally, the EMPD method is carried out using the program EnergyPlus to simulate moisture buffering performance at varying ventilation rates. Then, the Mold Germination Graph Method is used to evaluate the mold growth risk. The results show that Western Red Cedar can moderate the indoor moisture variation to decrease the mold germination rate. The evaluation results are especially significant in summer (July).
