ventilation different rate at night

I'm not sure, but is it possible to ventilate (mechanically or natural) at day at a rate of 1 ach and at night at a different rate?

Can I schedule a ventilation rate from 10 PM to 6AM ?

Hi Koen

Yes this is possible. You first need to open the Model Options dialog box (by clicking on the 'Building model options' toolbar button) and then select the '7/12 Schedules' Timing option on the Data tab. You can then set up a custom profile (from the Components browser tab) to define the variation in air change rate and use this profile to set up the required schedule. After setting up the schedule, you can specify it for mechanical/natural ventilation on the Model Data HVAC tab at the building, block or zone level.

If you need further information on profiles and schedules, you may find the 'Profiles' and 'Schedules'
sections under Help useful.
