# Space HVAC

A Space represents a thermal zone within a building that can be conditioned for the comfort of occupants. Each Space can have a different set of conditions associated with it. These include Schedules, Building Classes, Occupants, Internal Loads, Infiltration, Thermostats, HVAC, and Sizing. Where a diversity of Spaces exist in one building, they can be distributed across the model using tagging.

## Select Space HVAC 

To select Space HVAC, navigate to 'HVAC' and click 'Add HVAC' and then 'Add Space HVAC'. Next, under 'Type', select a preferred Space HVAC component, the 'Space' it is associated to and give it a 'Title' (Optional).
