I don't know about eQUEST, because my experience is only with the
DOE-2 engine that lies behind it, so you should take what I say with
a grain of salt.<br>
<br>
In DOE-2, the altitude of the building can be either read from the
weather file, or input separately by the user. The altitude that's
shown on the screen below seems to be taken from the weather file,
which may be why you can't change it. Check to see if that's true,
and if so, check if there's a way for a user input of altitude that
overrides what's on the weather file. It is possible to change the
elevation on the weather file, but since it's a binary (not an
ASCII) file, you have to use a couple of utility programs to convert
to text and then back to binary. However, I'm leery of large
arbitrary changes in altitude, like from 3,000 ft in El Paso down to
sea level, as you suggest, because the weather data would not be
right at all. Why can't you just change the weather file to that of
an appropriate sea level location? <br>

<p class="MsoNormal"><b>ISSUE #1<o:p></o:p></b></p>
<p class="MsoNormal">Thinking back, the past 20 LEED models or
so have been at sea level, lol. Now we’re of in Texas
somewhere, and we are not able to edit the red altitude field
below, so we adjust for the 1.16 altitude factor eQuest placed
on our airflows by lowering in our scheduled airflow. Now
when comparing to a LEED baseline model, the factor reappears
and we would like to eQuest to calculate those airflows, so
the analysis is skewed. Our LEED model is reporting higher
airflow due to the altitude correction factor. Now we are
back to changing the altitude to 0—but how? It allows us to
type something in but doesn’t change the number? Editing the
weather bin file isn’t easy either as it’s ASCII, and I’d have
to research an editor and format.<o:p></o:p></p>
