[BLDG-SIM] New Calculation method for Baseline Fan Energy in Addendum R

[Andrew Craig]

I was wondering if anyone out there can explain the new calculation
shown for baseline fan brake horsepower in Table G3.1.2.9 of Addendum R
to ASHRAE 90.1-2004?  At first glance, the equation doesn't make sense
because you are subtracting a relatively small number (0.0013+A) from a
large number (CFMs) leaving you with a ridiculously large baseline fan
motor brake horsepower.  Am I just reading this wrong or is there a
typo?  Isn't there an easier way out there to calculate baseline fan
energy (please see version 1 of Appendix G for another confusing
calculation)?
