Very nifty - don't know if anyone was curious, but this checks out
against the math in my personal spreadsheet.
Out of pure curiosity, does anybody else combine their baseline system
efficiency calcs (i.e. EIR) alongside their fan power calcs, or is it
normal to submit that separately... or not at all?

Actually the calculator has both the 2004 and the 2007 in separate tabs.

Keep in mind that calculator is only for 90.1-2004. Calculations have
changed substantially for 90.1-2007. Less restrictive for larger
systems, more restrictive for smaller systems.

Yes that is correct, the dot means multiplication.
The Excel calculator will come in very handy (credit to 7 Group)

Does the dot in the equation indicate multiplication? So should the
equation read CFMS X 0.0013 + A?
The reason I am confused is that they use X in other places.
Thanks in advance
