[BLDG-SIM] Loads not met interpretation in ASHRAE 90.1-2004

[Aulbach, John]

All:
 
ASHRAE 90.1-2004 has design criteria for Equipment capacities on Page
176 of the Standard (G3.1.2.2). It talks about Unmet load hours on the
proposed design AND the baseline design not exceeding 300 hrs (of 8,760
Hrs), and the delta between base and proposed not differing more than 50
hours.
 
Is this WHOLE BUILDING, or BY ZONE? I have 76 zones in my building, and
to play the Unmet loads game between these two models is harder than
trying to hold water in my hands.
 
Any thoughts, interpretations, or suggestions?
