Hi all,

Im a bit confused with the classification of Ashrae 90.1 2007, Im currently
modeling a facility of a total of 47,600 SF including a 28,000 SF
Warehouse. The facility includes 2 levels of offices, breakrooms, etc and a
double height warehouse adjacent to them. The proposed design is composed
of   2 AHUs, one for the first floor, one for the second and a only heating
and ventilation system based on 2 boilers for the warehouse. According to
this, the baseline should be a System 5 Packaged VAV with Reheat, Packaged
rooftop VAV with reheat, Direct expansion cooling type and  Hot-water
fossil fuel boiler for heating. One system per floor, but my confusion is
on the part of the warehouse. Should I model an additional Cool and Heat
System for the warehouse even though in the proposed we have it as only
heating and ventilation system? If so, does it have to be the same type of
system specified (System 5) or can it be System 3 or 4 instead?
