Lab Space ACH

I have a large 4 story building that i am modeling that is about 50 % lab
space set to 12 ACH and 100% OA and constant volume. I have created a
parametric run to turn down to 6 ACH and i am getting the same CFM and
utility bill information. Is there something i might be missing as an input
to either the model or the parametric run?

any help is greatly appreciated,

Hi Rob,

Remember that zone level OA inputs override system level OA inputs. Check if you're changing a system level input in the parametric run that is being ignored due to the 12 ACH OA value set at the zone level.
