Simulation with Passivent Roof Terminals
Once you have assigned and finalised Passivent Roof Terminals to rooms in your model, the model should be ready to simulate.
You can choose to manually run pre-thermal simulations, such as Suncast (a link is provided on the Navigator) or set these to run automatically by setting them ON with the Apache simulation dialog.
Clicking the Simulate System action under Thermal Simulation will switch to Apache view and display the Apache Simulation dialog.

In order to effectively simulate and view results for the Passivent Roof Terminals, the following simulation options are required:
- Enable SunCast Link? should be active if this has not already been generated manually.
- MacroFlo Link? should be active.
- ApacheHVAC Link? should be active for Airstract iAT® & Hybrid Plus Airstract® products
- Auxiliary ventilation air exchange? should be active.
- Natural ventilation air exchange? should be active.
- From / to? 1 Jan to 31 Dec.
- Simulation timestep? set to 10 mins (required for BB101:2018 CO2 checks).
- Reporting timestep? set to 10 mins (required for BB101:2018 CO2 checks).
If you want to see optional results detail, for example for ApHVAC component data, use output options to set this for selected rooms.
Once ready, you can start the simulation by clicking the Simulate button.
Once completed, the VE should switch to VistaPro for viewing and analysing the results.
