i am currently modelling an institutional building (2 Basements+G+7 Floors) in equest with VAV System without heating, I'm getting the unmet hours as follows
PERCENT OF HOURS ANY SYSTEM ZONE OUTSIDE OF THROTTLING RANGE = 81.83
PERCENT OF HOURS ANY PLANT LOAD NOT SATISFIED = 0.00
HOURS ANY ZONE ABOVE COOLING THROTTLING RANGE = 7169
HOURS ANY ZONE BELOW HEATING THROTTLING RANGE = 0
Have changed the throttling range from 2 to 4, but only very little change in unmet hours. Tried changing the outdoor air> flow per person & Air Flow> min design flow, but didn't get any change in unmet hours. Kindly help me how to reduce the unmet hours.
also showing warning in ATTN as follows
