The site data represents information about the site including its location, the conditions of the ground, weather, the legislative region and the maximum allowed U-values for new buildings. All buildings on the site use the same site model data.
To edit site model data, go to site level and click on the Location or Region tabs (below).
You can easily change the location of the site by making a selection for the Location template on the Location tab or by using the Load data from template command.
Alternatively you can open up the headers on the Location and Region tabs to edit the data.
