When you build a project in eQuest using the wizard, the HDD schedules are set to 0 for all internal loads.<br><br>When eQuest auto-sizes, it uses the weather file data and takes solar gain into account for both heating and cooling, if you need any. You can create custom heating and cooling design days that specify the hour at which the high and low temperature is reached. For a heating design day, the hour low could be specified to be at night, when there is no solar gain. Also, in LS-B and LS-C reports, the solar gain is clearly called out, if there is any solar gain during the heating design day, it cab be subtracted out of the total load for the space.<br>

<p class="MsoNormal"><span style="color: black;">I think there is another question
about how detailed your load calculation will be in breaking down the building
compared to the resolution required for your energy model, but you might be
able to navigate the differences successfully. And for some projects
there may not be much difference.</span></p>
<p class="MsoNormal"><span style="color: black;"> </span></p>
<p class="MsoNormal"><span style="color: black;">Also whether the same person is
doing both tasks, and their familiarity with both software packages.
Arturo, if you were doing both then great, but what if you have to hand the
load calc tasks off to someone at your office that doesn’t use eQuest?</span></p>

<p class="MsoNormal"><span style="color: rgb(31, 73, 125);">You are correct. Therefore one
would just have to schedule that to be off all the time in HDD. So are there
any other any concerns with using eQuest? Is the answer simply: It is easier to
get the load calculations from Trane Trace? </span></p>
