The exceptions haven’t changed between 2004 and 2007 so look at both for official interpretations of when to use those exceptions.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>In applying those exceptions, the baseline system from Table G3.1.1 must still be used for the predominant condition, held by ASHRAE and the USGBC/GBCI to mean the portion of the building with the larger square footage (i.e. the office portion of a warehouse is not the predominant condition). So even if one of the exceptions applied for your building, you would still have to model at least a portion of the building with the standard baseline from Table G3.1.1. (Peter – that is what the reviewers did not say, probably to stay clear of the GBCI’s rule about not offering design advice).<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Jeffrey – Table G3.1.1 is intended to apply to entire buildings, so unless the two wings are completely separate with no shared party walls, systems, foundations, etc. it will probably be difficult to get the reviewers to accept using a different baseline for both of the wings. If one of the exceptions does apply, it may be useful on one of the wings, but the submittal should include a detailed explanation of why the exception applies so the reviewers can understand the circumstances better – they tend to view the exceptions as being more or less rare.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div><p class=MsoNormal><b><span style='font-size:7.5pt;font-family:"Verdana","sans-serif";color:#1F497D'>Jeremy R.
