Use System Zones to group Spaces in your model into areas served by shared mechanical equipment.
An easy way to think about this is that each group of spaces sharing a single thermostat (or HVAC controller) is a separate System Zone. Some examples:
- Apartments or hotel rooms typically have a single zone, with a thermostat controlling the entire unit.
- If individual rooms in the unit have separate thermostats, each is a separate zone.
- Retail spaces often have their own zone, controlled separately from adjacent stores.
- Office spaces are often divided into many zones, each controlled by separate thermostats.
Give each System Zone a unique and easily recognizable name (using the Name instance property) to make it easier to identify the zone in analysis reports and schedules.
