[Bldg-sim] 90.1 VAV Baseline

My baseline system is System 5: Packaged VAV w/ reheat, but 90.1 doesn't
specify the minimum airflow percentage and I'm not sure what to use.
Equest defaults the min VAV airflow at 40% in core zones and 30% in
perimeter zones.  Increasing this number to 100% (cv) nearly doubles the
heating energy.  Since this is such a sensitive number, it's accuracy is
critical, what do you think I should use?
