Abstract: Variable Air Volume (VAV) Heating Ventilation and Air Conditioning (HVAC) systems are common design solutions for large buildings with complex zone arrangements. In designing and analyzing these systems, it was found that where the building has large high occupancy center zones combined with a range of perimeter conditions, it is very easy to build an energy model that meets the ventilation code but that might not be supplying enough outside air to maintain CO2 levels below a reasonable setpoint. This paper explores whether this is leading us to underestimate the energy of these systems and offers a review of analysis methods that may enable more accurate asssessment of performance.
