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. </div>

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.</div>

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.</div>

To complicate things, EQUEST has slightly different outputs than does DOE2.1e, but follows it pretty closely.</div>

Hope this helps. If you can't get your hands on the manuals let me know. I should be able to put a copy on the TAMU google drive for you.</div>
