<font face="Times New Roman, Times, serif">Once the people are gone
there are significant adjustments which can be made</font> to how the
building operates. You can set the fans to cycle on in unoccupied
hours, ie the just come on to maintain temperature. You can adjust
your unoccupied temperatures as well, "setback". The major adjustment
is outside air, no people, don't need it, just a little to control
off-gassing. Conditioning outside air is a major consumer of energy.
There are several ways to adjust this in eQuest.<br>
The hospital running 24/7 initially you would think should be the same
every day. There are things going on which may only happen on week
days which could change this. Operating theatres come to mind, which
can require large amounts of outside air during operation, labs and
fume hoods, laundry services. The population would be much higher
during 8-5 on week days, more outside air required.<br>
Equest has certain standard schedules (defaults) it will use for a
particular type of building. These are just crude assumptions.
Everyone of them should be reviewed and tuned to your project.<br>

<p class="MsoNormal">Hello,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I have been using EQuest to run some commercial
building simulations. I’ve found that the electric (DX) heating load
during weekends in the wintertime are unusually high compared to
weekday loads. I ran a building that was a hospital with 24/7 occupancy
and yet the heating loads between weekend and weekday are significantly
different. </p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Was there some hard- or soft-coded adjustment
made in the program for weekends?</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Thanks,</p>
