Summary, in English
This paper initially presents a blind method that could be used in order to verify heat and moisture calculation tools in a reliable manner. Furthermore, general results and findings from blind validations using a transient heat and moisture calculation tool are summarized and presented.The comparisons include measurements and calculations of temperature and relative humidity and were carried out in northern European climates.
In general, the results show a good correlation between measured and blindly-calculated values. Comparisons show that the studied tool can be used during the design phase to predict moisture risks. However, factors such as the influence of impaired-temperature measurements on relative humidity have to be taken into account. There is also a need for outdoor climate-boundary conditions that take into account critical periods.Measurementsandcalculations also established that themostmoisture-critical conditions ingeneral occurred in the exterior part of the frame, behind the air gap.
