Hi everyone, I'm new to OpenStudio and was trying to input an air leakage rate per exterior surface area for my model. I went to the "spaces" tab, then found "space infiltration design flow rates" and would like to insert data under "flow per exterior surface area [m/s]".

Question: Is the flow per exterior surface area input the measured value at 75Pa, or is it at some other pressure? I noticed the other items also don't have any pressure conditions so I'm a bit lost here.

Any insight would be greatly appreciated. Thanks!

I believe it is 4 Pa differential pressure but you could read about it yourself in the Input Output Reference. Also try the Engineering Reference.

Thanks for the info. I've read through the documents and noticed 4Pa is specified for Effective Leakage Area, but not specifically stated for the others.
