Fan Power determination for small motors isn't following App G

[jmarrec]

G3.1.2.9 Fan Motor Efficiency = the efficiency from Table 10.8 for the next motor size greater than the
bhp using the enclosed motor at 1800 rpm

To me this means that if bhp < 1 HP, you should look at 1 HP instead of "assuming PSC motor at 29% per a PNNL paper". I noticed that because the Section 1.4 tables from LEED were indicating my fan power for my "small" (<65 kBTU/h) PSZ-AC system group was way off.

I'll do a PR once I'm done working on my current project (for which I've modified a lot of code to suit my own needs)

Fixed by #106. Per 90.1-2010 addendum aj, as described in the PNNL's Enhancements to ASHRAE
Standard 90.1 Prototype Building Models, 2.4.2 Fan Motor Efficiency, most of these small motors fall in the 1/12 - 1 hp range and must therefore be EC motors or have an efficiency of 70%. For standards before 90.1-2013, assume PSC motors at 29% efficiency.
