Nick this too is the reason I am absolutely enjoying it. I was just telling my boss how your perception of design changes when you introduce what could actually be going on. I love the analogy Nick posted about trapping heat in the summer. It makes perfect sense because the more you insulate a building the better it is at NOT transmitting heat energy. So you put 1 piece of storefront on your building that introduces radiant heat to your floor and you’re cooking the inside or like you said one piece of equipment generating enough heat and it won’t let it escape.<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'>Thanks Nick light bulb just went off.<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'>Thanks,<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><b><span lang=DE style='font-size:10.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'>PETER HILLERMANN<o:p></o:p></span></b></p><p class=MsoNormal><span lang=DE style='font-size:10.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'><o:p> </o:p></span></p><p class=MsoNormal><span lang=DE style='font-size:8.0pt;font-family:"ITC Avant Garde Gothic Demi","serif";color:#1F497D;letter-spacing:1.0pt'><a href="mailto:peterh@westallarchitects.com">peterh@westallarchitects.com</a><o:p></o:p></span></p><p class=MsoNormal><span lang=DE style='font-size:10.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'><o:p> </o:p></span></p><p class=MsoNormal style='line-height:75%'><b><span lang=DE style='font-size:14.0pt;line-height:75%;font-family:"ITC Avant Garde Std Md","sans-serif";color:#1F497D;letter-spacing:1.0pt'>westall</span></b><span lang=DE style='font-size:14.0pt;line-height:75%;font-family:"Times New Roman","serif";color:#1F497D;letter-spacing:1.0pt'><o:p></o:p></span></p><p class=MsoNormal style='margin-left:4.0pt;line-height:75%'><b><span style='font-size:14.0pt;line-height:75%;font-family:"ITC Avant Garde Std Md","sans-serif";color:#1F497D;letter-spacing:1.0pt'>architects</span></b><span style='font-size:14.0pt;line-height:75%;color:#1F497D;letter-spacing:1.0pt'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'>3404 pierce drive<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'>chamblee, georgia 30341<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'>o 770.458.4113<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'>f 770.458.5352<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'>c 678.898.2936<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"ITC Avant Garde Gothic Demi","serif";color:#1F497D;letter-spacing:1.0pt'>westallarchitects.com</span><span style='font-size:12.0pt;font-family:"Times New Roman","serif";color:#1F497D;letter-spacing:1.0pt'><o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><img border=0 width=160 height=87 id="_x0000_i1029" src="cid:image004.jpg@01CB07CE.08C5F6C0" alt=e-signature><img border=0 width=92 height=90 id="_x0000_i1028" src="cid:image003.gif@01CB07CD.B0F816D0" alt=USGBC-Logo><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'><o:p> </o:p></span></p><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"'> Nick Caton [mailto:ncaton@smithboucher.com] <br><b>Sent:</b> Wednesday, June 09, 2010 12:03 PM<br><b>To:</b> Peter Hillermann; equest-users@lists.onebuilding.org<br><b>Subject:</b> RE: [Equest-users] U-Values<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='color:#1F497D'>Peter,<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'>This is the exact reason I’ve come to really enjoy energy modeling.
