[Equest-users] Lab Space ACH

[Matthew Dubrovich]

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.

Subject: [Equest-users] 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,
