The experimental set-up comprised a 40-feet (12.2 m) insulated reefer container with controlled indoor climate, reconfigured with several holes (1x2 m each) containing solid masonry walls with embedded wooden elements on the interior side and different internal insulation systems, with and without exterior hydrophobisation. The container was placed in Denmark. Throughout 1 year and 2 months, temperature and relative humidity were measured in the interface between the masonry and the internal insulation and in the embedded wooden elements. The effect of exterior hydrophobisation was also investigated. The VTT mould growth model was used to evaluate the mould risk. Lastly, the hygrothermal performance of the bio-based systems was compared with that of previously examined inorganic internal insulation systems. Findings for the two bio-based thermal insulation systems showed that exposed walls experienced high relative humidity. The combination with exterior hydrophobisation to lower intrusion of driving rain had a positive effect on the moisture balance for the masonry walls. However, the insulated walls with hydrophobisation still showed high relative humidity levels during specific periods of the year in some of the examined masonry walls. The mould risk evaluation showed a high risk of mould growth in masonry/insulation interface, as well as in the wooden wall plates in some test walls. <br>The dataset comprises an Excel file containing measurement data from the experimental set-up (1 hour data and 96 hour running average) and mould growth predictions calculated using the VTT model by Hukka and Viitanen.

摘要：本研究针对两种用于内保温改造的生物基保温系统（bio-based thermal insulation systems），即松散填充纤维素保温材料和大麻纤维保温材料（hemp fibre insulation），探究其湿热性能（hygrothermal performance）及霉菌生长风险。实验装置包含一个40英尺（12.2米）的绝缘冷藏集装箱，其室内气候可控；集装箱经改造开设多个孔洞（每个1×2米），孔洞内装有实心砖石墙，墙内侧嵌入木质构件，并采用不同的内保温系统（含外部疏水化处理与未处理两种情况）。该集装箱放置于丹麦。在1年2个月的时间内，对砖石墙与内保温层的界面及嵌入木质构件中的温度和相对湿度进行了测量，并探究了外部疏水化处理（exterior hydrophobisation）的效果。采用VTT霉菌生长模型（VTT mould growth model）评估霉菌风险。最后，将生物基保温系统的湿热性能与此前研究的无机内保温系统进行了对比。两种生物基保温系统的研究结果显示，暴露在外的墙体相对湿度较高。结合外部疏水化处理以减少风雨侵入，对砖石墙的水分平衡（moisture balance）具有积极影响；然而，在部分受测砖石墙中，经疏水化处理的保温墙在一年中的特定时期仍呈现高相对湿度水平。霉菌风险评估表明，砖石墙/保温层界面及部分测试墙的木质墙板存在较高的霉菌生长风险。
本数据集包含一个Excel文件，其中涵盖实验装置的测量数据（1小时数据及96小时移动平均值），以及采用Hukka与Viitanen提出的VTT模型计算得到的霉菌生长预测结果。
