[Equest-users] Repost - how to simulate a revolving door

[Julien Marrec]

Zarah,

If you break it down, here's what a door is:
- Thermal losses through the glass and frame: for that you define a Uvalue
for the door
- Infiltration when the door is closed
- Added Infiltration when the door is open

In your case, you could model added infiltration (schedule multiplier) for
the 30min shift change.

Best,
Julien
