Zone defaults
In this dialog, templates for new zones can be created and modified. A new template is created by modifying parameters and then saving under a new name (Save as ...). A library of typical zones can be created in this way.
Field descriptions, etc:
Use template
Choice from the list of alternative settings for new zones

General
Controller setpoints
Choice of control setpoints for temperature, air flow and quality, and light, etc.
Room units
Check to add ideal heating or cooling units to zones
Furniture
Covered part of the floor
Fraction of floor area which is covered by furniture. (0-1)
Weight / area with furniture
Total weight of furniture divided by the covered area. (kg/m2)
Room height
The distance between floor and ceiling (m). This parameter is only used for creation of new zones. If a zone is reset to match data in a template, zone geometry, including this parameter, is not touched.
Air
Select central air handling unit
Choice of air handling unit from the types available at the building level.
System type
Type of ventilation system. Constant or variable flow, with different controls.
Supply air for CAV
Mechanical supply airflow for CAV systems (l/s m2 floor area). VAV flows are given in Controller setpoints.
Return air for CAV
Mechanical return airflow for CAV systems (l/s m2 floor area). VAV flows are given in Controller setpoints.

Element of construction
External walls
Construction for external walls not described in the zone.
Internal walls

Internal gains
For automatic addition of occupant and equipment loads. These will be added to a new zone in proportion to the initial zone floor area. If the zone size is later on changed, the internal gains will not be changed automatically. But this can manually be done by >> Reset zone to template.
