<p class="MsoNormal"><span style="font-size:12.0pt;color:black">John's right, check the DOE-2 Reference Manuals, Part 2, which has a complete explanation between LS-D, SS-D and SV-A...as there's a big difference in the values being reported (LA-7890-M, LBL-8706
Rev.1). There is also useful information in the DOE-2 Basics manual. <o:p></o:p></span></p>

</div>
<div>
<p class="MsoNormal"><span style="font-size:12.0pt;color:black">In general, anything to do with LOADS is the simulation run at a constant indoor temperature, as well as other oddities that DOE-2 had in LOADS. So, SS-D would be coming from SYSTEMS, where the
actual space temperature was determined by weighting factors, and the load change accordingly. This would include thermostat setbacks, etc.<o:p></o:p></span></p>

<div>
<p class="MsoNormal"><span style="font-size:12.0pt;color:black"><o:p> </o:p></span></p>
</div>
<div>
<p class="MsoNormal"><span style="font-size:12.0pt;color:black">The SV-A report is not really a simulation result, but rather a verification of what you put into the simulation since much of what's in a DOE-2 input file is "hidden" in the defaults, only to
be seen in the LV, SV, PV outputs.<o:p></o:p></span></p>

<div>
<p class="MsoNormal"><span style="font-size:12.0pt;color:black">To complicate things, EQUEST has slightly different outputs than does DOE2.1e, but follows it pretty closely.<o:p></o:p></span></p>
