eQUEST Zone Groups

Whenever modeling multiple systems, or multiple system types in eQUEST’s DD wizard, it is helpful to assign zones using the “zone groups” feature.

Locate the zone group screen by editing a building shell and accessing screen 14. A zone group is a collaboration of zones that have the following common features:

-Assigned to the same HVAC system
-Common conditioning (conditioned/unconditioned)
-Percent area of occupancy types (i.e. 65% office space)
-exhaust fans

By default, all zones are assigned to a system. Default zone groups are divided by floor, and Perimeter/core spaces. The wizard automatically displays the selected zone group.

Sometimes, it is best to delete existing zone groups and start over. When deleting a zone group, all zones assigned to that group become unassigned and appear in Red when viewing the schematics at the bottom of screen 14.

A user may reassign them to an existing screen by clicking the appropriate zone, and selecting “Assign zone to other group” and selecting the appropriate group.

Alternatively, a user may highlight the group at the top, and select “assign zone to active group”

If the schematic diagrams on screen 14 are too small to adequately select zones, a user may click the appropriate floor’s button to view a larger version of the interactive diagram.

It is important to remember to do this in ALL shells. Remember to assign zones to the proper systems.
