unconditioned spaces. The unconditioned spaces contain loads from
electric water heaters and lighting and the water usage, itself. All of
these electric and water loads must, of course, be modeled.</span></font><o:p></o:p></p>

<div>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> However, these unconditioned spaces do
not include HVAC systems. The unconditioned spaces simply exhaust air
from the conditioned spaces to the outside via exhaust fans. I've been
advised by previous listserve e-mails to model the conditioned spaces as
directly exhausting to the outside.</span></font><o:p></o:p></p>

</div>
<div>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>1. How do I get eQuest to model the temperatures of
the unconditioned spaces without specifying HVAC systems (which don't
exist)? This is important insofar as the unconditioned spaces can conduct
heat to the adjacent conditioned spaces via shared interior walls/floors/ceilings.</span></font><o:p></o:p></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>2. In order to model the plumbing and lighting systems
(for water and electricity use), I have to assign them to spaces. If I
assign them to the conditioned spaces, this will artificially inflate their
affect on the cooling loads of those conditioned spaces. However, if I
assign them to the unconditioned spaces, then I have to assign those spaces to
respective thermal zones, which, in turn, require assignment to HVAC systems
that don't exist. How can this be simply and correctly modeled?</span></font><o:p></o:p></p>
