Not understanding the nature of PSE/PSF peaks causes a variety of similar misunderstandings (not isolated to fans). On the bright side, once you’ve handled such commentary once, for future cases you can usually copy/paste your previous response with minimal editing. The best comments are easy comments!</span></p><p class="MsoNormal"><span style="color:#002060"> </span></p><p class="MsoNormal"><span style="color:#002060">For many large buildings with VAV systems and also notably for buildings with a combination of different system types, there exists no meter report concerning fan energy which can be leveraged to verify inputs circuitously via “full load equivalent hours.” <u>Sometimes</u> the meter outputs actually work for this, but that’s the exception to the rule in my experience.</span></p><p class="MsoNormal"><span style="color:#002060"> </span></p><p class="MsoNormal"><span style="color:#002060">After double-checking to ensure there are no actual mistakes concerning system operations, fan inputs, etc, I typically craft a response starting with an explanation/review of what the peak values shown on PSE/PSF are & are not. The peak values in these reports break out, for each month, the portion energy drawn at the peak coincident hour <i><u>for that meter</u></i>. That may have little-to-zero correlation to the actual peak draw for the simulated fans (or any other isolated enduse). You’ll note the meter reports provide a “maximum” peak value at the bottom (after the December row). I typically use these numbers for the EAp2 enduse reporting. These values however are the maximum peak value from the 12 monthly peaks reported for the corresponding column. For the same reasons, this is not necessarily the same value as the peak enduse draw independent of everything else going on in the model.</span></p><p class="MsoNormal"><span style="color:#002060"> </span></p><p class="MsoNormal"><span style="color:#002060">I then would advise/clarify for the reviewer that the fan kW value reported on SVA system reports for may be referenced <u>directly</u> to verify the results of our fan power inputs (these values should match the value ‘Pfan’ reported/calculated for your baseline systems, and also the fan power sourced for your proposed case systems, as reported on the EAp2 excel template). If I’m in a good mood, I’ll slap in some screenshots showing the interface inputs and highlight a that portion of an SVA output to make it plain as day in my response.</span></p><p class="MsoNormal"><span style="color:#002060"> </span></p><p class="MsoNormal"><span style="color:#002060">~Nick</span></p><p class="MsoNormal"><span style="color:#002060"> </span></p><div><p class="MsoNormal"><b><span style="font-size:14.0pt;color:#002060">NICK CATON, P.E.</span></b><span style="font-family:"Verdana",sans-serif;color:#1f497d"><br></span><b><span style="color:#561782">Owner</span></b></p><p class="MsoNormal"><b><span style="color:#561782"> </span></b></p><p class="MsoNormal"><b><span style="font-size:10.0pt;color:#561782">Caton Energy Consulting</span></b><span style="font-size:10.0pt;color:black"><br></span><span style="font-size:10.0pt;color:#1f497d"> 603 N Ferrel</span></p><p class="MsoNormal"><span style="font-size:10.0pt;color:#1f497d"> Olathe, KS 66061</span></p><p class="MsoNormal"><span style="font-size:10.0pt;color:#1f497d"> office: 785.410.3317</span></p><p class="MsoNormal"><span style="font-size:10.0pt;color:#561782"><a href="www.catonenergy.com"><span style="color:#561782">www.catonenergy.com</span></a></span><span style="color:#002060"></span></p></div><p class="MsoNormal"><span style="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>From:</b> Equest-users [mailto:<a href="mailto:equest-users-bounces@lists.onebuilding.org">equest-users-bounces@lists.onebuilding.org</a>] <b>On Behalf Of </b>Jones, Christopher<br><b>Sent:</b> Wednesday, July 22, 2015 8:33 AM<br><b>To:</b> Travis Miller; <a href="mailto:equest-users@lists.onebuilding.org">equest-users@lists.onebuilding.org</a><br><b>Subject:</b> Re: [Equest-users] Supply fan kW for LEED Table 1.4</p></div></div><p class="MsoNormal"> </p><p class="MsoNormal"><span style="font-family:"Franklin Gothic Book",sans-serif;color:#1f497d">Especially for a VAV system.
