AHUs it would help the documentation. However if the DHW is switched off manually for the season there might be some pushback that modeling losses would be appropriate in case it doesn’t actually get deactivated, or if there might be the occasional event at
the school during the summer time?<o:p></o:p></span></p>

<p class="MsoNormal"> <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">I'm currently modelling a school building in eQuest for the LEED for Schools 2009 certification. The school doesn't operate at all in the summer season (closed) and so it isn't equipped with equipment for cooling.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"> <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">I have made schedules modelling this principle (not operating in JUNE/JULY/AUGUST) at both proposed and baseline scenarios but I'm concerned if it is mandatory or not to model a full year's operation under LEED. In the months of operation,
I have modelled both cooling/heating as it is mandatory.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"> <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">A second question is how to make the DHW heater not to operate at the summer months. Having tried everything and after doublechecking that there is no DHW demand from the annual schedule for the summer months, the result is that the DHW
loop and pump show no use for these months (seen at the simulation output) but still the DHW heater is operating consuming significant gas for an unknown reason. Loop is set to demand operation and recirculation set at 0.01.<o:p></o:p></p>
