Hi I am modeling a building with baseline system as 5 now based on Table G 3.1.1 , it says we need to model 1 VAV system per floor, now In reality I have 4 VRF units per floor , should I model one system 5 for all those 4 units ? Also for 2nd floor I have 4 VRF units but some of them are serving level-1, if I model system 5 for floor 2 , should I exclude the spaces on level-1 but in that case we wont be modeling based on Table G3.1.7 which says thermal zones in baseline model should be modeled the same way modeled in proposed.
