You can sum heating (ONLY) coil loads to determine the output. This is a clip from the guideline we use in Canada (BC) that explains it. M.F.Area is building area excluding unconditioned indoor parking area, but including all other partially and unconditioned areas. So yes, the answer is option B, excluding the cooling. It is not the peak (A) and does not include heating system efficiency (C).<o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal"><span style="mso-ligatures:none"><div><image003.png></div></span><o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">Shaun<o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal"><span style="mso-ligatures:none">Shaun Martin, BEMP, LEED-BD&C<o:p></o:p></span></p><p class="MsoNormal"><span style="mso-ligatures:none">Principal<o:p></o:p></span></p><p class="MsoNormal"><span style="mso-ligatures:none">Shaun Martin Consulting<o:p></o:p></span></p><p class="MsoNormal"><span style="mso-ligatures:none"><a href="mailto:smartin@shaunmartinconsulting.com"><span style="color:#0563C1">smartin@shaunmartinconsulting.com</span></a><o:p></o:p></span></p><p class="MsoNormal"><span style="mso-ligatures:none">+1-604-789-1095<o:p></o:p></span></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal"><o:p> </o:p></p><div><div style="border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in"><p class="MsoNormal"><b><span style="mso-ligatures:none">From:</span></b><span style="mso-ligatures:none"> Bldg-sim <bldg-sim-bounces@lists.onebuilding.org> <b>On Behalf Of </b>Madhav Munshi via Bldg-sim<br><b>Sent:</b> Thursday, July 27, 2023 2:14 PM<br><b>To:</b> bldg-sim@lists.onebuilding.org<br><b>Subject:</b> [Bldg-sim] Mass Stretch Code: TEDI calcs<o:p></o:p></span></p></div></div><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal"><span style="font-family:"Arial",sans-serif">Hi group, <o:p></o:p></span></p><p class="MsoNormal"><span style="font-family:"Arial",sans-serif"><o:p> </o:p></span></p><p class="MsoNormal"><span style="font-family:"Arial",sans-serif">Hope everyone is doing well. We are working on a school building in MA and need to perform “TEDI” models. I’ve read through the documentation and am a little confused if it’s a load metric or an energy metric. The limits are expressed in kBtu/sf/year in the code language, but some of the supporting documentation about how to extract this from equest/IES/ energy plus makes me feel like it’s a load metric. It has to be one the three and it seems like its option B<o:p></o:p></span></p><p class="MsoNormal"><span style="font-family:"Arial",sans-serif"><o:p> </o:p></span></p><ol style="margin-top:0in" start="1" type="A"><li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level1 lfo3"><span style="font-family:"Arial",sans-serif">Peak Heating and Cooling load per SF<o:p></o:p></span></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level1 lfo3"><span style="font-family:"Arial",sans-serif">Sum of annual heating and cooling loads (annual) per SF – without efficiency accounting <o:p></o:p></span></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level1 lfo3"><span style="font-family:"Arial",sans-serif">Sum of annual heating and cooling energy per SF – with efficiency accounting<o:p></o:p></span></li></ol><p class="MsoNormal"><span style="font-family:"Arial",sans-serif"><o:p> </o:p></span></p><p class="MsoNormal"><span style="font-family:"Arial",sans-serif"><a href="https://www.mass.gov/doc/updated-guidelines-for-tedi-and-ashrae-app-g-modeling/download">https://www.mass.gov/doc/updated-guidelines-for-tedi-and-ashrae-app-g-modeling/download</a><o:p></o:p></span></p><p class="MsoNormal"><span style="font-family:"Arial",sans-serif"><o:p> </o:p></span></p><p class="MsoNormal"><span style="font-family:"Arial",sans-serif">Appreciate your responses!
