<html><head><style type="text/css"><!-- DIV {margin:0px;} --></style></head><body><div style="font-family:arial,helvetica,sans-serif;font-size:12pt"><div><p>I'm modeling a high bay manufacturing facility for the purpose of the
Energy Efficient Commercial Building Tax Deduction. Baseline building
must be modeled to ASHRAE 90.1-2004, Appendix G.</p><p><br></p><p>The proposed
building has constant volume heating/ventilating units with 100% OSA.
Additionally they have a make-up air unit, with heating, that only
operates when the doors are open and trucks are inside running and being
unloaded.</p><p><br></p><p>Can anyone give guidance on how to handle this type of
system in eQUEST, since eQUEST will only allow one HVAC system per
zone? Also I'd need the operation schedule for this unit to be
different than the HVAC op hours for the rest of the building.</p><p><br></p><p>Also
per 2004 ASHRAE, this must be System 5, VAV with cooling. So when I
model the proposed building, I'll need the system to be constant volume
with cooling, which will probably cause problems with the energy use
relative to baseline. Can the proposed building air distribution system
be VAV, with cooling and heating at the AHU, for example?</p><p><br></p><p>Thank you,</p>Pete</div>
