Include Zone

Activity tab in model data under Activity Template header


Include zone in thermal calculations

By default zones are included in the heating and cooling design calculations and simulations 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 this option on the Activity tab for zones as appropriate.


Note: To access this data there must not be any zone merging selected. If you need to exclude zones and this checkbox is disabled then you should disable zone merging first in order to access it.

Tip: In large models it is sometimes easiest to uncheck this option at building level and just include the zone(s) of interest.

Note: 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.

Include zone in daylighting calculations

Zones which are not regularly occupied, or which for any other reason should not be included, can be excluded from daylighting calculations by unchecking this option. This option can be used when carrying out a LEED, BREEAM or Green Star daylighting credit calculation to avoid including zones that are not regularly occupied in the building assessment.


From the LEED 3 documentation:

Regularly occupied spaces in commercial buildings are areas where people sit or stand as they work. In residential applications these spaces include all living and family rooms and exclude bathrooms, closets, or other storage or utility areas. In schools, they are areas where students, teachers, or administrators are seated or standing as they work or study.
