Activity tab in model data under Activity Template header
By default zones are included in the model but they can be excluded. You may wish to exclude a zone or series of zones from the analysis to focus on a smaller part of the building for example a single shop within a mall and in this case you should uncheck the Include zone option on the Activity tab for zones as appropriate.
Surfaces between included and excluded zones are modelled as being adiabatic, i.e .heat is transferred into the wall mass as if the temperature of the excluded zone is the same as the included zone.
