size=2 face=Arial>If you have the as-built drawings, as you mentioned, then you
should set the model up using the actual building and equipment efficiency
values from your building drawings, that are confirmed by any site
visits, rather than using the default values in the program, which are
typically minimum energy code requirements, as you mention. You should be
able to then do base model runs that approximate the existing building's
actual 2-3 year average energy usage. Of course, you might have to
adjust your model to get it to match the actual historical energy usage of the
building within 1-2%, unless you are not required to have that close of
accuracy. Any way, yes, a 12 year old building likely would have
higher energy usage than one built meeting to today's energy code requirements,
that is, of course, unless the building 12 years ago was built to a standard
that was better than the present energy code. </FONT></SPAN></DIV>

[SPAM][Equest-users] First Building Performance Simulation<BR></FONT><BR></DIV>
<DIV></DIV><FONT color=black size=2 face=arial>
<DIV>All:</DIV>
<DIV> </DIV>
<DIV>I have just performed my first simulation using eQuest. I modeled an
existing building that is about 12 years old. The project went well and
there were few unknowns because I had free access to the original building
plans. I have a couple of questions now. </DIV>
<DIV> </DIV>
<DIV>If I understand correctly, the model developed by eQuest assumes
a minimum level of efficiency that is compliant with ASHRAE 90.1 or
California Title 24 (see page 4 of the Introductory Tutorial). If this is
the case, then it is entirely possible (or expected) that the electric or fuel
consumption will be lower than actual if the original building was not designed
to be compliant with ASHRAE 90.1 or California Title 24. </DIV>
<DIV> </DIV>
<DIV>Does everyone see it this way a well?</DIV>
<DIV> </DIV>
<DIV>Thanks,</DIV>
