What if there are a number of different fan schedules in the 
building?  Do you multiply the 2% from BEPS for all systems?  What if 
only one zone on one system has unmet hours - how do you use the BEPS 
report to calculate which zone and for how many hours?

It seems to me that the SS-R report provides the most useful 
information for determining which systems/zones are under heated/cooled.

In Andrew's case, I believe the reviewer is off his/hers rocker - 
asking that the SS-R and BEPS report match.
