Settings relating to whole building Profiles, HVAC, Modelling and Reference assumptions are all located in the Simulation area.
HVAC assumptions are available for Ideal Loads, Package Variable Air Volume and Variable Refrigerant Flow (Air-to-Air) systems. Variable Refrigerant Flow is the default for Australian commercial buildings, and Ideal Loads are the default for New Zealand residential buildings.
Select and amend HVAC preferences by selecting 'HVAC' in the Simulation area. Click 'Save' once done.
