Then (post-wizards) straight up delete each roof surface section that’s “fully sandwiched.” This isn’t <i>perfect </i> and you’ll end up with a series of “fully exposed” and “partially sandwiched” sections, which in the scheme of a large multistory building is usually in the ballpark of “good enough” for many simulation contexts. This approach balances early time savings with later flexibility: you can always come back and tweak those partially sandwiched sections (delete and remake as a rectangle of appropriate area) if you feel it’s a big deal later on, though at that point you lose the pretty appearance in 3D.</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">… although I very much like Keith’s suggestion and will try to remember that option for the next go-around =)! </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">That “U-value adjusted for area” approach could also be combined with any number of other geometry strategies to save time in “later on” adjustments. </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><div><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"><br></span><span style="font-size:10.0pt;font-family:"Calibri",sans-serif;color:#1f497d"> 306 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></div><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#002060"> </span></p><div><div style="border:none;border-top:solid #e1e1e1 1.0pt;padding:3.0pt 0in 0in 0in"><p class="MsoNormal"><b><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:windowtext">From:</span></b><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:windowtext"> Equest-users [mailto:<a href="mailto:equest-users-bounces@lists.onebuilding.org">equest-users-bounces@lists.onebuilding.org</a>] <b>On Behalf Of </b>Keith Swartz<br><b>Sent:</b> Tuesday, October 27, 2015 3:38 PM<br><b>To:</b> John Aulbach; Equest-users<br><b>Subject:</b> Re: [Equest-users] The old "too much roof" dilimena</span></p></div></div><p class="MsoNormal"> </p><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif;color:windowtext">John,</span></p><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif;color:windowtext"> </span></p><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif;color:windowtext">Another method I have heard of is adjusting the U-value for the roof so that the product U*Area remains constant. The BTU’s of heat transferred through the roof is the same. The roof load is not distributed correctly to the rooms below, which might be OK if it’s a big open space. This method follows the principle that you aren’t modeling the building, you are modeling the <u>energy use</u> of the building. It is usually better to model the building as closely as you can, so I prefer Bruce’s method of putting an air wall under the boundary of the roof to make it easier to delete unneeded roof polygons. (An even better solution is to use software that does not have this problem!)</span></p><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif;color:windowtext"> </span></p><div><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">Keith Swartz, PE </span><span style="font-size:10.0pt;font-family:"Arial",sans-serif;color:gray">| </span><span style="font-size:10.0pt;font-family:"Arial",sans-serif">Senior Energy Engineer</span></p><p class="MsoNormal" style="line-height:110%"><b><span style="font-size:10.0pt;line-height:110%;font-family:"Arial",sans-serif">Seventhwave</span></b><span style="font-size:10.0pt;line-height:110%;font-family:"Arial",sans-serif;color:gray"> | </span><b><span style="font-size:10.0pt;line-height:110%;font-family:"Arial",sans-serif;color:#5f5f5f">Madison.Chicago.Minneapolis</span></b><b><span style="font-size:10.0pt;line-height:110%;font-family:"Arial",sans-serif;color:gray"></span></b></p><p class="MsoNormal" style="line-height:110%"><span style="font-size:10.0pt;line-height:110%;font-family:"Arial",sans-serif">608.210.7123 <a href="http://seventhwave.org">seventhwave.org</a></span></p></div><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif;color:windowtext"> </span></p><div><div style="border:none;border-top:solid #e1e1e1 1.0pt;padding:3.0pt 0in 0in 0in"><p class="MsoNormal"><b><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:windowtext">From:</span></b><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:windowtext"> Bruce Easterbrook [<a href="mailto:bruce5@bellnet.ca">mailto:bruce5@bellnet.ca</a>] <br><b>Sent:</b> Tuesday, October 27, 2015 8:05 AM<br><b>To:</b> John Aulbach <<a href="mailto:jra_sac@yahoo.com">jra_sac@yahoo.com</a>>; Equest-users <<a href="mailto:equest-users@lists.onebuilding.org">equest-users@lists.onebuilding.org</a>>; Brian Fountain <<a href="mailto:bfountain@greensim.com">bfountain@greensim.com</a>><br><b>Subject:</b> Re: [Equest-users] The old "too much roof" dilimena</span></p></div></div><p class="MsoNormal"> </p><p class="MsoNormal" style="margin-bottom:12.0pt">I match the zone or zones on the floor below to the footprint of the floor above.
