90.1-2007 requires a system 5 with a fossil fuel hot water boiler as you have
modeled, but in 90.1-2007 Table G3.1 Number 10 HVAC Systems Base Building
Performance column it states that you need to meet any system-specific
requirements in Section G3.1.3.<br>
<br>
In G3.1.3.2, it states that for system 5, the boiler plant shall use the same
fuel as the proposed design, which in your case is electric resistance and
compressor heat pump energy. I would model electric hot water boilers.<br>

<div>
<p class="MsoNormal"><font face="Calibri" size="2"><span style="font-size: 11pt; font-family: Calibri;">Dear eQuesters,</span></font></p>
<p class="MsoNormal"><font face="Calibri" size="2"><span style="font-size: 11pt; font-family: Calibri;"> </span></font></p>
<p class="MsoNormal"><font face="Calibri" size="2"><span style="font-size: 11pt; font-family: Calibri;">I just got LEED review comments for my project. Our
proposed design is VRF system with roof top unit providing ventilation air.
Roof top unit is using gas as heating source. There are misc. elec. heaters in
the building for places like entries. I interpreted my building heating source
as “electric hybrid” and used hot water fossil fuel boiler as my base design.
The comments I got read as the follows:</span></font></p>
<p><i><font color="blue" face="Times New Roman" size="2"><span style="font-size: 10pt; color: blue; font-style: italic;">Section 1.1.A of the form indicates that
the primary heating source is fossil fuel. However, the electric heating energy
use reported in Table EAp2-5 for the Proposed Case exceeds the fossil fuel
heating energy use. Please verify that the correct heating source has been
selected. If electric heating is the primary heating source, please change the
Baseline system type accordingly. Provide updated simulation results and a
revised Prerequisite Form as necessary.</span></font></i></p>
<p><font face="Calibri" size="2"><span style="font-size: 11pt; font-family: Calibri;">I
couldn’t find an official definition either on LEED reference book or 90.1.
What is your take on this?</span></font></p>
<p><font face="Calibri" size="2"><span style="font-size: 11pt; font-family: Calibri;">Your
input is highly appreciated! Thank you very much!</span></font></p>
