Hello,
I am trying to model and events space and connecting offices. I have two separate systems for these areas. The events space (zone 1) is being cooled using the AHU supply air via the ventilation system purely and the offices will be conditioned by a VRF Systems with the terminal units being FCU's.
As the events space will suffer from Solar gain there is a chance that we will have to naturally ventilate the area as well as use the ventilation system for cooling. How would I specify the individual systems in the Part L section on Heavacomp? Would I tick the mixed mode box in the cooling system tab?
Thanks
