<p>Yongqing is correct. This kind of information is not available
in any of the hourly reports, but it can be calculated although
depending on the complexity of the building it might almost feel
like you're writing a small loads calculation program :-) <br>
</p>
<p>I worked with a Research Associate (Ellen Franconi, now at the
Rocky Mountain Institute) to do this using FUNCTIONs in DOE-2.1E,
but since FUNCTIONS are not invoked in DOE-2.2/eQUEST, you'd have
to write out hourly reports for the LOADS loads for each exterior
surface and then adjust the loads for the difference between the
constant LOADS temperature and the actual zone temperature in
SYSTEMS using a simple UA delta T correction, i.e., Loads
Correction = (UA of surface)*(Tsystem - Tloads). You can get the
U-value and area of each surface from the LDS verification
report. For infiltration, instead of a UA use the air volume
times its specific heat. Once you've done all this, you will have
the actual heat flows to the building, but these will not
correspond to the SYSTEM Loads because of the temperature
deadband. After trying various approaches, Ellen and I found the
best to be aggregating the heat flows when the system is off, and
then dumping it to either heating or cooling depending on the
system mode when it starts up again. Don't expect complete
correspondence with the System Load, but generally we were getting
within 5-10%.<br>

Hi,Saurabh <br>
<br>
<div>Sorry,maybe I don't make my question clear. </div>

</div>
<div>the procedure of the building loads's
calculation in eQUEST is shown as following:</div>
<div>
<p><span
style="font-family:'verdana';font-size:11pt"> In
Loads, all the heat flows are calculated at
the reference temperature (TLOADS) and counted
as Cooling if the net space load that hour is
positive or Heating if it's negative. In
Systems, these loads are corrected to the
actual zone temperature and the load from OA
and interzone heat transfer added, while
solving for the zone temperature. If the zone
temperature is outside the thermostat
deadband, a deficit would be considered a
heating load and an excess as a cooling load
on the HVAC system.(posted by Joe huang)</span><span
style="font-family:'verdana';font-size:11pt"><br>
</span></p>
</div>
<div><b>And monthly building load components(such as
building load from roof,building load from wall
and building load from window conduction etc.)
are listed in LS-F report. But all these results
in LS-F report are calculated based on the
reference temperature(TLOADS),which is a fixed
value assumed by user,not the actual zone
temperature.My question is how to get the
building components that are calculated based on
actual zone temperature!</b></div>
