--- SYSTEM HAS ADEQUATE EXPOSURE DIVERSITY. ---

System is on N, E, S, W rosette.Peak load exceeds 13-hour average load by 17.3%.

Definition: A system has adequate exposure diversity if the peak-hour glass load for the entire conditioned space does notexceed the average glass load for the entire conditioned space by more than 20 percent (N, E, S, W rosette), or by morethan 30 percent (NE, SE, SW, NW rosette).
