    WUFI® celebrates its 25th anniversary

    Our software family has now been established in the professional world for 25 years and is internationally recognized - planners, building product manufacturers, construction companies and experts from more than 100 countries use the various products of the WUFI® family. The programs are also implemented for research and teaching purposes at numerous educational institutions and universities. Which WUFI® software products exist? How can moisture in buildings be evaluated in practice? What are the basic principles behind hygrothermal simulation, what input data are required and how can the results be evaluated? In this jubilee year, Dr. Simon Schmidt, head of the Department of Hygrothermics at Fraunhofer IBP, will be addressing these questions in various weekly training videos. The institute makes the videos available on the YouTube channel.

    All further information about the anniversary will also be prominently presented on this landing page.

    Survey on the application of hygrothermal simulation software

    You know mould, thermal bridges, algae and frost damage from your daily planning and construction practice?

    Up to now simplified methods such as thermal bridge or the so called Glaser or dew point calculations are mainly used for that purpose. Increasingly, however, more sophisticated hygrothermal simulation programs like WUFI® or DELPHIN are applied.

    However, in practice, planners are often in doubt, which evaluations and proofs of function they need, how they can interpret the simulation results correctly and finally how reliable input data and results are.

    Moisture in buildings – Highly relevant all over the world

    Moisture management in buildings is a trending topic, as moisture related problems not only affect old buildings, but energy efficient new ones as well. In the United States, roughly 50% of all households reported the prevalence of dampness and mold.  European households discovered these same issues, reporting them in about 20% of households.

    The Fraunhofer Institute for Building Physics IBP has conducted research in this field for many years, and is dedicated to solving to these problems by providing software, experience, and solutions to organizations such as ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers). With contributions of Fraunhofer experts, a new chapter on moisture management in buildings was developed for ASHRAE’s Handbook of Fundamentals.
