<html><body bgcolor="#FFFFFF"><div>Hi Andres, adding to the EUI discussion, one thing to keep in mind is that CBECS data is collected in 2003, pre-90.1-2004, and a baseline built to 90.1-2007 should see 10-20 kBtu/ft2 less. That being said, your EUI should be 1/7th of what you are seeing. eQUEST is able to assign multiple equipment schedules; you may find your excessive EPD as you scroll over to the right, on your internal gains / equipment spreadsheet.<br><br><div><span class="Apple-style-span" style="-webkit-tap-highlight-color: rgba(26, 26, 26, 0.28125); -webkit-composition-fill-color: rgba(175, 192, 227, 0.214844); -webkit-composition-frame-color: rgba(77, 128, 180, 0.214844);"><br></span></div><div><span class="Apple-style-span" style="-webkit-tap-highlight-color: rgba(26, 26, 26, 0.28125); -webkit-composition-fill-color: rgba(175, 192, 227, 0.214844); -webkit-composition-frame-color: rgba(77, 128, 180, 0.214844);">Arpan Bakshi</span></div></div><div><span class="Apple-style-span" style="-webkit-tap-highlight-color: rgba(26, 26, 26, 0.28125); -webkit-composition-fill-color: rgba(175, 192, 227, 0.214844); -webkit-composition-frame-color: rgba(77, 128, 180, 0.214844);"><br></span></div><div><br>On Oct 27, 2011, at 1:04 PM, "Nick Caton" <<a href="mailto:ncaton@smithboucher.com">ncaton@smithboucher.com</a>> wrote:<br><br></div><div></div><blockquote type="cite"><div><div class="WordSection1"><p class="MsoNormal"><span style="color:#1F497D">Hi Andres,<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">If you’re not defining glazing then your model’s envelope is at best akin to opaque glass… Thermally it’s probably about the same thing at night… but not once sun rises.

If you have a client interested in measuring performance using EUI, I would sooner research my own baseline by identifying the annual consumptions of a building similar in size, region and occupancy to draw comparisons against.<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">Someone else may have an alternative recommendation for EUI “rules of thumb” resources… I believe the onebuilding archives contain discussions on the topic.<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">~Nick<o:p></o:p></span></p><div><p class="MsoNormal"><span style="color:#1F497D"><image003.jpg></span><b><span style="font-family:"Stylus BT","sans-serif";color:#2D4D5E"><o:p></o:p></span></b></p><p class="MsoNormal"><b><span style="font-family:"Stylus BT","sans-serif";color:#2D4D5E"><o:p> </o:p></span></b></p><p class="MsoNormal"><b><span style="font-size:12.0pt;font-family:"Stylus BT","sans-serif";color:#2D4D5E">NICK CATON, P.E.</span></b><b><span style="font-size:12.0pt;font-family:"Stylus BT","sans-serif";color:#2D4D5E"><o:p></o:p></span></b></p><p class="MsoNormal"><span style="font-size:7.5pt;color:#CC9900">SENIOR ENGINEER<o:p></o:p></span></p><p class="MsoNormal"><span style="font-size:7.5pt;color:#CC9900"><o:p> </o:p></span></p><p class="MsoNormal"><span style="font-size:10.0pt;color:#2D4D5E">Smith & Boucher Engineers</span><span style="font-size:7.5pt;font-family:"Times New Roman","serif";color:#CC9900"><o:p></o:p></span></p><p class="MsoNormal"><span style="font-size:10.0pt;color:#2D4D5E">25501 west valley parkway, suite 200<o:p></o:p></span></p><p class="MsoNormal"><span style="font-size:10.0pt;color:#2D4D5E">olathe, ks 66061<o:p></o:p></span></p><p class="MsoNormal"><span style="font-size:10.0pt;color:#2D4D5E">direct 913.344.0036<o:p></o:p></span></p><p class="MsoNormal"><span style="font-size:10.0pt;color:#2D4D5E">fax 913.345.0617<o:p></o:p></span></p><p class="MsoNormal"><span style="color:#1F497D"><a href="www.smithboucher.com" title="blocked::www.smithboucher.com"><span style="font-size:10.0pt">www.smithboucher.com</span></a></span><u><span style="font-size:10.0pt;color:blue"> </span></u><span style="color:#1F497D"><o:p></o:p></span></p></div><p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p><div><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> [mailto:equest-users-bounces@lists.onebuilding.org] <b>On Behalf Of </b>Andres Franco Usme MicroCAD S.A.S<br><b>Sent:</b> Thursday, October 27, 2011 8:33 AM<br><b>To:</b> <a href="mailto:equest-users@lists.onebuilding.org"><a href="mailto:equest-users@lists.onebuilding.org">equest-users@lists.onebuilding.org</a></a><br><b>Subject:</b> [Equest-users] Glazing envelope<o:p></o:p></span></p></div></div><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">Hi everyone,<o:p></o:p></p><p class="MsoNormal">First of all, I want to say thanks’ for all your useful help, secondly I have another doubt, In my project the building envelope is a double glazing tilt wall, I’m using as construction for the envelope a material with the same u value specified for the glass contractor, but I’m not using windows, this procedure can affects the results in energy consumption, cooling temps, etc?, third, the values that I had are big?
