霉菌生长对大量现有建筑物及其使用者构成高风险。通过建筑物墙壁的空气腔（此处为墙壁和穿透墙壁的空调器管道之间的间隙）的空气泄漏可能增加间隙冷凝、霉菌生长和其他与湿气相关的问题的风险。为了量化由于空气通过空气腔泄漏而导致的霉菌生长风险，选择了中国南京的一个历史砖石建筑中的办公室，并对其室内环境进行了研究。在靠近墙体空气腔的内侧空调管道表面可见真菌定植。湿度温度计和热电偶记录了2018年6月至2020年1月的室内和室外温度以及相对湿度。实测数据表明，夏季室外湿度远高于室内，而空气腔附近的温度低于室内其他部位的温度。湿热的室外空气可能会凝结在靠近空气腔的冷壁表面上。进行了二维湿热模拟。通过空气腔壁的空气泄漏被证明是一个至关重要的因素，霉菌生长。
Mold growth poses a high risk to a large number of existing buildings and their users. Air leakage through the air cavities of the building walls, herein gaps between walls and air conditioner pipes penetrating the walls, may increase the risks of interstitial condensation, mold growth and other moisture-related problems. In order to quantify the mold growth risks due to air leakage through air cavity, an office room in a historical masonry building in Nanjing, China, was selected, and its indoor environment has been studied. Fungi colonization can be seen on the surface of air conditioner pipes in the interior side near air cavity of the wall. Hygrothermometers and thermocouples logged interior and exterior temperature and relative humidity from June 2018 to January 2020. The measured data show that in summer the outdoor humidity remained much higher than that of the room, while the temperature near the air cavity stays lower than those of the other parts in the room. Hot and humid outdoor air may condense on the cold wall surface near an air cavity. A two-dimensional hygrothermal simulation was made. Air leakage through the air cavities of walls proved to be a crucial factor for mold growth.
