Passive2:Dialog Climate

Unlike WUFI®Plus, WUFI®Passive does not hourly data for calculation.

Localization

In the localization tab you can select your climate file. By clicking on the section cope, you can click on "user defined" and browse your own climate file. As WUFI®Passive does not need hourly data, it does need a different kind of climate files. It can only read .txt and .xls files with a special formation. This formation can be generated with meteonorm. See pictures below for examples.

Example .txt

Example .xls

If you have different climate files, you can still load them using WUFI®Plus. Click here for detailed instructions. When switching back, WUFI®Passive will automatically convert the data into the fitting format.

Climate

Similar to WUFI®Plus this section gives you short summary about the climate file.

Temperature

The first section shows the mean temperature of each month, which is also shown in the left graphic. On the very right the extreme weather conditions are shown, which are needed to calculate the heating load of the building.

Solar radiation

The second section contains the mean monthly solar irradiation, seperated into the four cardinal points. The right picture also shows the course of the graph and again on the very right, there are extreme weather conditions.
