Dear All,
We are modelling a Baseline Building with System 8 “VAV + PFP boxes” using HAP by Carrier.
We are wondering how to model the VAV + PFP boxes according to ASHRAE 90.1 Section 3.1.3.14.
Should we calculate the peak air flow rate (cooling mode I understand) using Baseline Building data (Lighting,building envelope..) or Proposed Building data?
