On April 23-24, 2019, the "WUFI® (Heat and Moisture Unsteady State Calculation) Training Conference" was held at MiG (Zhejiang) Innovation Technology Co., Ltd. Heinrich Tillmann, a lecturer in the Department of Civil Engineering, Grenoble National School of Architecture and Joseph Fourier University in France, was invited to give lectures for this training.

Once the training notice was issued, various architectural research and design units, building materials manufacturers and other relevant units have enthusiastically registered. In order to achieve the desired results of the conference, professional scientific researchers from China Academy of Building Research, China Building Materials Inspection and Certification Group, China Urban Science Research Association and other units were invited to participate in this training.

The thermal and wet physical properties of building components and houses are closely related: increased humidity will increase heat loss; temperature changes in building components also affect humidity transfer. Therefore, the study of the two must focus on their coupling; this is the research content of thermohygroscopy.

The trainees said that through this study, they learned about WUFI® (Heat and Moisture Unsteady State Calculation), which was developed by the Fraunhofer Institute of Building Physics (IBP) in Germany and verified by open-air experiments and laboratory data around the world Calculation method; and mastered the use of WUFI® Pro program. WUFI® Pro combines the water content of the building material itself, wind-driven rain, solar radiation, long-wave radiation, capillary transmission and summer condensation influencing factors, and can simulate the one-dimensional thermal and moisture characteristics of the standard cross-section of building components. Traditional static evaluation methods such as the Glaser method do not take into account the influence of these factors, which limits their evaluation of winter condensation protection. WUFI® Pro can simulate the dynamic thermal and moisture performance of building components under real climatic parameters in accordance with the requirements of DIN EN 15026.

The "Technology Today" column of Zhejiang Satellite TV's Educational Technology Channel conducted follow-up shooting and special reports on the training meeting.
