9/12/19 CEC - I was doing a quick comparison with my simple HRR model using COM 1.0. I have one model at 7 stories, then just changed it to 8 stories at the Building Data Tab to compare the baseline HVAC systems (mainly doing space heat comparison). I noticed that the Fan Power is a lot lower with the 7-story model (ducted zonal system?) than the FPFC. I would think it should be opposite since FPFC is ductless and 0.35 W/CFM. Do you know why that is? I attached my two files.
