Double HVAC system per zone

Marcus Sheffer LEED Fellow 7group / Energy Opportunities LEEDuser Expert 5903 thumbs up February 13, 2019- 10:26 am As you indicate most software can't model two systems in one zone. So this would likely be very software specific. I'd suggest this part of the question is better served on one of the software specific forums at onebuilding.org. If you are trying to find out which software can do this I would think that EnergyPlus is the most likely. The DOAS with FC is a common system type that most software has a methodology for modeling. It again varies by software as some can model...
