台灣位於亞熱帶氣候區，屬於高濕高熱的氣候型態，容易導致生物性污染，故有效率的室內濕度調節與控制對於室內空氣品質及人類健康相當重要。本研究以花旗松為研究對象，以實驗求得材料熱濕物性，作為數值模擬參數，再利用EnergyPlus軟體中，有效滲透深度（EMPD，Effective Moisture Penetration Depth）簡算法進行空間熱濕環境模擬，比較調濕建材使用面積以及室內通風換氣量與調濕性能之關係，以評估花旗松對於台灣典型住宅寢室空間的調濕性能。根據結果，室內建材花旗松具有良好調濕效果，可緩和室內濕氣變動量，減少相對濕度80%－100%發生率，降低室內生物性污染產生；且結果顯示調濕建材搭配通風換氣，可得到較佳室內調濕效果，達到較好的空氣品質。

Taiwan is located in the subtropics and has a climate with high temperature and humidity, which leads to high indoor moisture that causes biological pollutants. A moisture buffering effect is proposed to improve indoor air quality and human health. The hygroscopic character of Douglas fir is investigated as a parameter for numerical simulation. Additionally, the EMPD (Effective Moisture Penetration Depth) method is carried out using the program EnergyPlus to simulate moisture buffering performance with varying ventilation rates and quantities of Douglas fir. The results showed that Douglas fir can moderate the indoor moisture variation to decrease the appearance frequency of high humidity and to improve indoor air quality.
