calculation is the same; however report sheet LS-D from each program is for a
specific hour of a day and of course the peak load happens on different days at
different times of the year which means you’re comparing red delicious
apples to granny smiths. We’re going to be parsing the 8760 data from the
hourly reports at some point to see if we can’t figure out if the
internal loads are different, if a specific shell component is yielding significant
losses, or if the whole building is just being calculated differently. I was
just hoping someone might have some insight into what’s going on and
could point me in the right direction. <o:p></o:p></span></p>

<p class=MsoNormal style='margin-left:.5in'>Did you have a look at infiltration
values, schedules and calculation method (effects of outside T and V)?. Since
Std.90.1 does not fix this values both programes could be using different
defaults with a significant impact on heating demand.<br>

En/na Eric O'Neill ha escrit: <o:p></o:p></p>
<p class=MsoNormal style='margin-left:.5in'>Good evening all, <o:p></o:p></p>
<p class=MsoNormal style='margin-left:.5in'> <o:p></o:p></p>
<p class=MsoNormal style='margin-left:.5in'>So we’re beginning the
transition from VDOE (DOEv2.1e) to eQuest (DOEv2.2), and we noticed that eQuest
tended to result in higher space heating requirements. We have attempted to
reconcile the difference, but even when we set two baseline buildings as
closely as possible in their respective program - setting as many details the
same as we could - we still couldn’t get similar space heating results.
Most of electric consumptions were close enough, however the space heating
section results indicated about a 40% more heating in eQuest than in VDOE. The
eQuest model is showing about 0.67 therms/square foot for something similar to
an ASHRAE baseline (although it’s not exactly) which seems high. <o:p></o:p></p>
<p class=MsoNormal style='margin-left:.5in'> <o:p></o:p></p>
<p class=MsoNormal style='margin-left:.5in'>In a similar fashion, I’m
working on a NAPA autoparts store, which, as most know, are extremely simple.
My output there is about 0.76 therms/square foot. I built it to the dimensions
that they gave me, however I set all the components to the ASHRAE 90.1 standard
and left the remainder as defaults. <o:p></o:p></p>
<p class=MsoNormal style='margin-left:.5in'> <o:p></o:p></p>
<p class=MsoNormal style='margin-left:.5in'>Has anyone else experienced this? <o:p></o:p></p>
