<p class="MsoNormal"><span style="color:#1F497D">Possibly a clarification & question combination:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">The PS-E Report is for all electrical meters; the PS-F lets the modeler dig into individual meters if the project is configured correctly.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">This is the clarification/question part: The PS-E report does
<u>not</u> display the peak draw at the building coincident load, the PS-E shows the peak draw and when it occurs for
<u>each</u> end-use type. From the eQuest Vol 4-Libraries & Reports: <o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">“Max kW: The maximum power consumption for each end-use and total during the month. This is the peak consumption per end-use;
<u>the peak for a given end-use may not be coincident with the peak for the meter, or with the peaks for other end-uses</u>. The meter’s peak is in the last column.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Day/Hr: The day and hour at which the peak and total end-use consumption occurred.” [underline emphasis is mine]<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">A minor, but important distinction as well is that for the building summary at the bottom, the day/hr row is replaced with a mon/dy row; which makes sense, but important to note the change.<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">In my quick review of a few projects, the peak draw day/hr for the individual end-uses are hit & miss if they occur at the same time as the building-wide peak coincident day/hour.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<div>
<p class="MsoNormal"><span style="color:#1F497D">In summary, the PS-E report peaks [at the bottom] should be the report used to fill out the online EAp2 form, Table EAp2-4 and Table EAp2-5. The SV-A report[s] are good for getting/checking the fan power draw

<p class="MsoNormal"><span style="color:#002060">This is one of those common boilerplate reviewer mistakes I’ve seen time and again. 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><o:p></o:p></p>
<p class="MsoNormal"><span style="color:#002060"> </span><o:p></o:p></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><o:p></o:p></p>
<p class="MsoNormal"><span style="color:#002060"> </span><o:p></o:p></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><o:p></o:p></p>
<p class="MsoNormal"><span style="color:#002060"> </span><o:p></o:p></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><o:p></o:p></p>

</div>
</div>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Which output report should be used when tabulating supply fan power in Table 1.4 of the excel file for LEED submittal?<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">I initially tabulated this kW number from the SV-A reports, which is different than the PS-E report. The PS-E report was used to fill out tables EAp2-4 and EAp2-5 of the online template. The LEED reviewer picked up on this and wants me
to revise and resubmit. <o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">I would assume that difference in these reports is due to the fact that the total building demand kW for ventilation fans does not happen at the same time that each individual system demand kW happens – is that a correct assumption?<o:p></o:p></p>
