If our Baseline building design HVAC system is ASHRAE’s #6 or #8 (according to TABLE G3.1.1B). Do we have to calculate and simulate both, fan power according to section G3.1.2.9 (System Fan Power, for AHU) and fan power according to section G3.1.3.14 (Fan Power, Systems 6 and 8, for PFP Boxes)?

Thanks in advance.
