Depending on the objective of Geof's investigation, I'd like to add
a note of caution about these DOE commercial reference buildings,
something that I was involved in first creating 5 years ago.
Although these have evolved substantially beyond the shoeboxes of
the 1990's, they are still prototypical building models that are
quite simple in comparison to models based on real buildings. If
your intention is to investigate how EnergyPlus performs under
stress conditions, there are far larger and more complex realistic
building models out there. Unfortunately for Geof, the great
majority of them have been created <br>
using DOE-2 or eQUEST. Over the past year, I've been asked to help
convert such models to EnergyPlus, once by someone at LBNL! Now
these are what I would call large building models, one had over 400
spaces and over 2,000 surfaces. <br>

<p class="MsoNormal"><span style="font-size: 11pt; font-family:
"Calibri","sans-serif"; color: rgb(31,

why I suggested these. The reason is that some of the
system types change between the new construction (per ASHRAE
90.1-2004) models and the existing building (“post1980” and
“pre1980” construction) models, so this would give you a
broader set of models. Also, the lighting power is higher,
and the infiltration is much higher for these existing
building models. This can sometimes make the simulations
different enough (warm-up time, HVAC iterations, etc.) that
you might want to check with these existing building models,
too. If you don’t want to look at all of them, then you may
just want to do pre1980 in a few cities.<o:p></o:p></span></p>
