Space Infiltration Effective Leakage Area Object: Problem with Schedule with OpenStudio 2.7.0

openstudio
infiltration
retag add tags

Hi, Using OpenStudio2.7.0, I think there is a problem with SIELAO. We have no more the possibility to add a schedule on the SIELAO. So, when I run the simulation, I have the following error message:

"* Severe * <root>[ZoneInfiltration:EffectiveLeakageArea][Space Infiltration Effective Leakage Area 1] - Missing required property 'schedule_name'.".

Is it a known issue, or am I doing something wrong? Thx!

I think I see what's your problem. On the "Space Type" tab there's no problem because there's a dropdown for the schedule next to it:

On the 'Space' tab, it's a little bit weirder indeed, but you can do it anyways.

You have to go to "Properties > Airflow" and drag your infiltration.

Then you need to switch to the "Loads" tab and you'll see the dropdown to drag your schedule. (I guess the confusion comes from the fact that on the "Loads" tab you can only drop a "Definition" object).

You can assign a fractional schedule to this the same way you can to space infiltration design flow rate objects. You can use a schedule set for the impacted space or space type, making sure the schedule set has an infiltration schedule assigned. You can also directly assign a schedule to an infiltration instance in a space or space type. Unlike most internal loads which have a schedule drop zone, for infiltration objects you need to use a pull down menu in the edit pane at the right side of the application while.the infiltration object is selected.
