For systems featuring a “force shade/clear” function, I haven’t found great guidance to reinforce when/how occupants might use that feature, so it becomes a tricky matter to carry into the simulation without a series of my own assumptions. If anyone has come across some research or polling along these lines I’d like to add that to my library!</span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#002060"> </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#002060">~Nick</span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#002060"> </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#002060"> </span></p><p class="MsoNormal"><b><span style="font-size:14.0pt;font-family:"Calibri",sans-serif;color:#002060">NICK CATON, P.E.</span></b><span style="font-size:11.0pt;font-family:"Verdana",sans-serif;color:#1f497d"><br></span><b><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#561782">Owner</span></b></p><p class="MsoNormal"><b><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#561782"> </span></b></p><p class="MsoNormal"><b><span style="font-size:10.0pt;font-family:"Calibri",sans-serif;color:#561782">Caton Energy Consulting</span></b><span style="font-size:10.0pt;font-family:"Calibri",sans-serif;color:black"><br></span><span style="font-size:10.0pt;font-family:"Calibri",sans-serif;color:#1f497d"> 603 N Ferrel</span></p><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Calibri",sans-serif;color:#1f497d"> Olathe, KS 66061</span></p><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Calibri",sans-serif;color:#1f497d"> office: 785.410.3317</span></p><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Calibri",sans-serif;color:#561782"><a href="www.catonenergy.com"><span style="color:#561782">www.catonenergy.com</span></a></span><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#002060"></span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#002060"> </span></p><p class="MsoNormal"><b><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">From:</span></b><span style="font-size:11.0pt;font-family:"Calibri",sans-serif"> Equest-users [mailto:<a href="mailto:equest-users-bounces@lists.onebuilding.org">equest-users-bounces@lists.onebuilding.org</a>] <b>On Behalf Of </b>Brian Cline<br><b>Sent:</b> Tuesday, July 21, 2015 5:32 PM<br><b>To:</b> <a href="mailto:equest-users@lists.onebuilding.org">equest-users@lists.onebuilding.org</a><br><b>Subject:</b> [Equest-users] Problem with Sage Glass Analysis</span></p><p class="MsoNormal"> </p><div><div><div><div><p class="MsoNormal" style="margin-bottom:12.0pt">Hi,</p></div><p class="MsoNormal" style="margin-bottom:12.0pt">I am attempting to model energy saved by installing electrochromic glass for use in a large west facing lobby area into eQUEST. Given that eQUESTS capabilities only include modeling a single tint for a pane of glass in a shell, how would I go about analyzing electricity consumption with the electrochromic glass for each hour over the course of a year?
