Evaluation of Mould Growth on Wall Surface by Different Models

Indoor mould growing on the wall surface can not only degrade building materials, but also endanger occupants’ health. It is of great significance to study the mould growth, especially for domestic research. This paper takes the thermal bridge of building as an example, which is located in Shanghai. Then the hourly temperature and relative humidity were obtained. And the VTT model, MRD model and WUFI-BIO model are used to calculate for assessing the mould growth in one year. From the result, the mould growth in Shanghai is mainly concentrated in summer. The three models evaluate mould growth in different ways. And the VTT and MRD model show that the mould growth time is longer than MRD model in Shanghai. The description of VTT model is relatively straightforward in the result display. Besides, according to the prediction principle, the MRD model covers the wider influencing factors of mould growth.
