<p class=""><span style="color:rgb(31,73,125)">Thank you so much for your respond.</span></p>
<p class=""><font color="#1f497d">All the inputs are eQUEST defaults; with your suggestions I have
to revise them. I reviewed Section 7 of ASHRAE 90.1-2007, but I couldn't find
related data for the baseline model. I have the exact data for the proposed
model based on the MEP engineer calculations but if I input those data for the
baseline model the project will not achieve any savings from this category. It
would be very helpful if you let me know where I can find these data.</font></p>

<p class="MsoNormal">Dear eQUEST experts,<u></u><u></u></p>
<p class="MsoNormal">I have Electrical Water Heater for the Residential and Non-residential parts of this model. I allowed eQuest to auto-size domestic hot-water use. BEPS report shows huge electrical consumption for DHW, more
than the total consumptions of all others. Is there something wrong?<u></u><u></u></p>
