<DIV><FONT face=Arial size=2><SPAN class=199211015-21092009>
Here's my latest fiasco:</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=199211015-21092009> I
have some conditioned and some 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></DIV>
<DIV><FONT face=Arial size=2><SPAN class=199211015-21092009>
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></DIV>
<DIV><FONT face=Arial size=2><SPAN class=199211015-21092009>
The problems are these:</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN

<DIV><FONT face=Arial size=2><SPAN class=199211015-21092009>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></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=199211015-21092009></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=199211015-21092009>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></DIV>
