Space infiltration pressure values / units

edit

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!
