Dear all

I am working for a factory project and in large production area all supplied
cfm from AHU is going exhaust so 100% outdoor air is provided. Its
conditioned area is about more than 1,50,000 Sqft. Total conditioned area is
about 3,00,000 SSqft.

My question is which system is applicable for Baseline and since my supply
air is greater than 5000 cfm so heat recovery is required.

Also how can I treat exhaust air from machines? Can I model this exhaust
fan as process load.
