In lieu of the SUN SPACE and temperatures, we determined hourly heat transfer (pos and neg) between the cavity and interior zones using TRNSYS. We then created an hourly load schedule to be applied to the perimeter zone in eQUEST. I had originally thought to make the perimeter wall adiabatic but decided to approximate that by creating a glass type with very high thermal resistance and SHGC of ~0. The Tvis value was still active and could thus accommodate the daylighting addition. Looking back I would go with adiabatic and do daylighting within TRNSYS so that the heat transfer from cavity to zone in TRNSYS took any electrical lighting reductions into account. A reminder that modeling never achieves perfection.<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'>Paul<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><table class=MsoNormalTable border=0 cellpadding=0 width=474 style='width:355.5pt'><tr><td width=167 valign=top style='width:125.25pt;padding:.75pt .75pt .75pt .75pt'><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><b><span style='font-size:10.0pt;font-family:"Calibri","sans-serif";color:#660000;text-transform:uppercase'>Paul Erickson</span></b><b><span style='font-size:9.0pt;font-family:"Calibri","sans-serif";color:#333333'> </span></b><span style='font-size:9.0pt;font-family:"Calibri","sans-serif";color:#333333'>LEED® AP BD+C <br></span><span style='font-size:10.0pt;font-family:"Calibri","sans-serif";color:#333333;text-transform:uppercase'>Sustainable</span><span style='font-size:9.0pt;font-family:"Calibri","sans-serif";color:#333333'><o:p></o:p></span></p></td><td width=10 valign=top style='width:7.5pt;padding:.75pt .75pt .75pt .75pt'><p class=MsoNormal><span style='font-size:9.0pt;font-family:"Calibri","sans-serif";color:#333333'> <o:p></o:p></span></p></td><td width=283 valign=top style='width:212.25pt;padding:.75pt .75pt .75pt .75pt'><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><b><span style='font-size:9.0pt;font-family:"Calibri","sans-serif";color:#660000'>AEI</span></b><span style='font-size:9.0pt;font-family:"Calibri","sans-serif";color:#333333'> | AFFILIATED ENGINEERS, INC. <br>5802 Research Park Boulevard | Madison, WI 53719<br><br></span><span style='font-size:9.0pt;font-family:"Calibri","sans-serif";color:#660000'>P: 608.236.1112 | F: 608.238.2614</span><span style='font-size:9.0pt;font-family:"Calibri","sans-serif";color:#333333'> <br></span><span style='font-size:9.0pt;font-family:"Calibri","sans-serif";color:#660000'><a href="mailto:perickson@aeieng.com"><span style='color:#660000;text-decoration:none'>perickson@aeieng.com</span></a> | </span><b><span style='font-size:9.0pt;font-family:"Calibri","sans-serif";color:#660000'><a href="http://www.aeieng.com"><span style='color:#660000;text-decoration:none'>www.aeieng.com</span></a></span></b><span style='font-size:9.0pt;font-family:"Calibri","sans-serif";color:#333333'> <o:p></o:p></span></p></td></tr></table></div><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";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"'> equest-users-bounces@lists.onebuilding.org [mailto:equest-users-bounces@lists.onebuilding.org] <b>On Behalf Of </b>Jackson, Alan<br><b>Sent:</b> Wednesday, March 09, 2011 8:52 AM<br><b>To:</b> equest-users<br><b>Subject:</b> Re: [Equest-users] double-skin curtain wall in equest<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>We recently had to perform this analysis and worked with another consultant who developed a mathematical model to determine the DSF cavity temperatures throughout the year.

One of the approaches that we’ve used was to couple a CONTAM + TRNSYS cavity model with an eQUEST model. The eQUEST portion of this needs to be dealt with in the detailed mode. If you don’t need to use eQUEST, there are various tools that can directly model DSF variants to one extent or another (i.e. TRNSYS, Energy Plus, IDA ICE, IES-VE, etc.). These are fairly complex tools and can still be limited for some of the DSF configurations out there.
