You shouldn’t depend on a LEED reviewer to determine the accuracy of your methodologies. The fan power calcs are not always right. Sometimes they work, sometimes they don’t. If want to be sure, always back-check via hand calcs. Scott’s comment regarding “kW/cfm” is very important. Don’t input anything as “horsepower”. If you enter a 10hp fan, you’re going to get a 10kW fan. It’s not a unit display issue, it’s actually using 10kW. Motor efficiency is already included in the Appendix G calc if you are performing it correctly.

From my experience the LEED reviewer will not accept the automatic fan calculation within Trace. You need to manually calculate the maximum break HP for each fan for the baseline systems. I recommend putting them in units of kW/CFM. You will need to manually do the fan power calculations according to 90.1 and adjust for any "allowances" per 90.1. Please don't use the Full Load Energy Rate numbers I have used. You'll need to calculate these for your specific conditions per 90.1 requirements.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><img border=0 width=609 height=385 id="Picture_x005f_x005f_x005f_x0020_5" src="cid:image006.jpg@01CDFA45.6C00C690"><o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Scott<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"'> Caballero, Catalina [<a href="mailto:ccaballero@jalrw.com">mailto:ccaballero@jalrw.com</a>] <br><b>Sent:</b> Thursday, January 24, 2013 9:03 AM<br><b>To:</b> Scott Parker; <a href="mailto:trace-users@lists.onebuilding.org">trace-users@lists.onebuilding.org</a><br><b>Subject:</b> RE: Part load conditions<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='color:#1F497D'>Can the software calculate it automatically with the following feature on?<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'><img border=0 width=282 height=57 id="Picture_x005f_x005f_x005f_x0020_4" src="cid:image010.jpg@01CDFA45.6C00C690"><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'>Regards,<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'>Catalina<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"'> Scott Parker [<a href="mailto:sparker@aeieng.com">mailto:sparker@aeieng.com</a>] <br><b>Sent:</b> Thursday, January 24, 2013 9:01 AM<br><b>To:</b> Caballero, Catalina; <a href="mailto:trace-users@lists.onebuilding.org">trace-users@lists.onebuilding.org</a><br><b>Subject:</b> RE: Part load conditions<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='color:#1F497D'>Catalina,<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'>You can define a custom fan curve based on the 90.1 cubic equation, but I would recommend that you use the 90.1 fan curve library member that comes with the program.
