thank you, sorry for my not well explanation.
Baseline is system 8, one VAV per floor.
For the proposed i have injector fans, they will supply outdoor air to each zone, there will be chiller and duct but without any coil. tenat will install the coils.
So, (option)what i have modeled is the injector fans, and there include a coil of cold water and in each zone include the paralel box like in the baseline.
Another way (option 2)that i can model is model VAV that will supply outdoor air and cooling equal than in my baseline, but, what about my injector fans that will supply outdoor air (i can simulate it double).

i dont know wheter option 1 or potion 2 is correct.
thank you
