<p class="MsoNormal"><span style="color:#1F497D">Thanks for the feedback. As I asked Bill offline, and I feel it goes without saying, but never hurts to be thorough :-): this applies to the old HVAC systems too, correct? Obtaining the old HVAC system info
could be a daunting challenge unfortunately.<o:p></o:p></span></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span style="color:#1F497D">Agreed. Take note there are a couple nuances between what’s written in 90.1 and what’s required by the LEED reviewership. I believe they draw a line in the sand where if more than 50% of a project is “retrofit”
vs. NC by square footage, then rotations go away.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">I just had 3 LEED projects wrap up at silver/gold where in the initial submission I used thoroughly documented prescriptive baseline envelopes and 4 rotations. The preliminary review commentary required changing
the envelopes to remove the rotations and match reality instead. The previous reality was (mostly) uninsulated grout filled block walls, single pane windows without film treatments, and zero wall insulation =D!<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">As a net result, each of these projects jumped way up in unanticipated modeling credits. It was a good day.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Outside the constraints of LEED, the closer your baseline models can reflect existing realities, the better and more informative the results of your models become for a retrofit analysis.<o:p></o:p></span></p>

<p class="MsoNormal">This question isn't eQuest specific, but deals with 90.1 interpretation.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">For an existing building, with regards to shell alterations, G3.1.5-f says that "the baseline building shall reflect existing conditions prior to any revisions that are part of the scope of work being evaluated." Is this statement as far-reaching
as I believe, indicating that U-values, SHGC etc, listed in Tables 5.5 and Appendix A are ignored in a similar way as done in the proposed, since the "baseline" in this case is a real design, rather than a hypothetical baseline?<o:p></o:p></p>
