For LEED compliance under ASHRAE 90.1, are the 300 unmet hours the sum of all the unmet hours in each zone, or the peak per zone? In other words if I have 250 unmet hours in one zone and 250 unmet hours in another zone, does this comply, or is it considered 500 unmet hours total? By zones, I mean thermal zones served by the same air handling unit. Thanks.
