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.<br>
The climate file is chosen in the localization tab. WUFI's predefined climate is a reference year of Germany and can be altered by using the "user defined" tab in the scope and by browsing the desired climate file.<br>
Due to WUFI®Passive not using hourly data, different climate files and formations are needed. So far WUFI can read .txt and .xls files as seen in the screens below and in [http://www.wufi-wiki.com/wufifilme/flash/climate_data_input.swf this movie]. To obtain these files/formation you can use meteonorm.<br>

If you have different climate files, you can still load them using WUFI®Plus. [[Plus_2.X:Dialog_Climate|Click here]] for  detailed instructions. When switching back, WUFI®Passive will automatically convert the data into the fitting format.

The climate tab summarizes temperature and radiation data in a table and a graph. The picture on the right can be used as a reference for the description.

Similar to WUFI®Plus this section gives you short summary about the climate file.
=== Temperature ===
=== 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.<br>
The upper table shows the monthly mean ambient temperature and, if given in the climate file, the sky, ground and dew point temperature, though they are not necessary for the calculation. The extreme weather condition on the right end are needed to calculate the heating and cooling loads 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.
The lower section contains the mean monthly solar irradiation, separated into the four cardinal points and also the extreme weather conditions.

Though differences are minor, WUFI knows 3 different standarts regarding the values of this table. If you do have different ones, you can set your own table in the "user defined" section.

Unlike WUFI®Plus, WUFI®Passive uses monthly climate data rather than hourly data.

Localization

Localization

The climate file is chosen in the localization tab. WUFI's predefined climate is a reference year of Germany and can be altered by using the "user defined" tab in the scope and by browsing the desired climate file.
Due to WUFI®Passive not using hourly data, different climate files and formations are needed. So far WUFI can read .txt and .xls files as seen in the screens below and in this movie. To obtain these files/formation you can use meteonorm.

Example .xls


Climate

The climate tab summarizes temperature and radiation data in a table and a graph. The picture on the right can be used as a reference for the description.

Climate

Temperature

The upper table shows the monthly mean ambient temperature and, if given in the climate file, the sky, ground and dew point temperature, though they are not necessary for the calculation. The extreme weather condition on the right end are needed to calculate the heating and cooling loads of the building.

Solar radiation

The lower section contains the mean monthly solar irradiation, separated into the four cardinal points and also the extreme weather conditions.

Primary energy/CO2-factor

Primary Energy

In this tab, you can see and set the primary energy factor (PEF) and the CO2-emission factor (CO2EF).

The PEF is multiplied by the site energy demand to determine the Primary Energy Demand. The PEF is influenced by both the production process and the transportation of the energy source, and therefore varies depending on the chosen fuel source.

The CO2EF converts the energy demand into an equivalent amount of CO2, also dependent on the chosen fuel source. These two factors are important when looking into the sustainability and carbon footprint of the passive building.
