Most of the guidance in Table G3.1 for the Proposed model indicates it must be modeled as designed. This is where appendix A comes in for the Proposed constructions. U-values may only be calculated using the inverse of the sum of the R-values if each layer is continuous (e.g. uninterrupted by other materials such as steel studs or joists). Appendix A provides tables with the effective U-values for various common heterogeneous constructions. Depending on the construction, the overall U-value for the assembly can vary significantly from the U-value calculated by summing the U-value of the major components. The Appendix A assembly performance must be used for the Proposed constructions to accurately reflect performance of the building envelope. Hope this helps.</span><o:p></o:p></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Have a great day!</span><o:p></o:p></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Cam Fitzgerald</span><o:p></o:p></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Energy Opportunities/a 7group company</span><o:p></o:p></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'> </span><o:p></o:p></p><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> <a href="mailto:equest-users-bounces@lists.onebuilding.org">equest-users-bounces@lists.onebuilding.org</a> [<a href="mailto:equest-users-bounces@lists.onebuilding.org">mailto:equest-users-bounces@lists.onebuilding.org</a>] <b>On Behalf Of </b>Pasha Korber-Gonzalez<br><b>Sent:</b> Thursday, April 11, 2013 6:00 PM<br><b>To:</b> eQUEST Users List<br><b>Subject:</b> [Equest-users] LEED Review Comment for Appendix A constructions</span><o:p></o:p></p></div><p class=MsoNormal> <o:p></o:p></p><div><p class=MsoNormal>Hi -- hopefully others have run into this before.
