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?

The peak airflow rate comes from the Baseline at the zone level which has been auto-sized by the software.

Is it acceptable to model a split-type AC with inverter technology compressor as a heat pump, like modeling VRF?

A portion of our building envelope is historic. Can we exclude it from our model?

Our project has a large process load—75%. Despite our efforts to make an efficient HVAC design, the cost savings are minimal. What can we do to earn this prerequisite and be eligible for LEED certification? Is there any flexibility in how we model the p

Our process load is higher than 25%. Do we have to justify that?

Our local code references ASHRAE 90.1-2010. Should I use that for my documentation, or 90.1-2007?

Can I claim exterior lighting savings for canopy lighting even though a baseline model cannot include shading elements?

The project is built on a site with existing exterior lighting installed. How should this be accounted for?
