the kW/CFM is based on the Baseline BHP and Baseline Fan Power formula in
ASHRAE 90.1-2004 G3.2.1.9. The CFM is the total building CFM”,
90.1-2007 makes it the most clear that the CFM is actually ONLY the Baseline’s
peak SUPPLY CFM. The same is true for 90.1-2004, it’s just not very
clear. However the reviewers do know that this is true and have most
recently been asking for a demonstration of calculation methodology.<o:p></o:p></span></p>

believe that the kW/CFM is based on the Baseline BHP and Baseline Fan
Power formula in ASHRAE 90.1-2004 G3.2.1.9. The CFM is the total building
CFM; see the air-side summary report for the total bulding CFM. <o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>To
get the correct total building CFM, set the Baseline supply-air-to-room-air at
a 20-degree F differential. For instance, if your summer (cooling)
set-point temp = 75 degreesF, then the cooling supply air temp from the
unit is 55-degree F. If your winter (heating) set-point temp is 70-degree
F, then your heating supply air temp from the unit is 90-degree F.
Run a simulation and eQUEST will determine the CFM for each system based on
this differential; then balance the systems to be under the 300 unmet
hours limit. Then open the air-side summary report to see the
total CFM of all your systems. Use that total CFM in the BHP and Baseline
Fan Power calculations under G3.2.1.9. To use the formulas, you need to
use a calculator with a "natural log" button and an "e"
button for the energy constant (e=1.28....just like "pie" =
3.14).<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>For
a Baseline Type 3 PSZ System, the fan power should be in the neighborhood of
0.0007; this may be why GBCI questioned your result. Then assign
this fan power to each baseline PSZ system in your building and re-run the
simulation. Include the formula in the LEED submittal template or
narrative to demonstrate how its calculated; as well as including the Air-side
Summary Report. GBCI will see both the total baseline CFM and the
baseline fan power calculations.<o:p></o:p></span></p>

Proposed conditions are the proposed set-points, proposed supply air temps, and
proposed kW/CFM for each system as designed. If the RTU fans run
continuously during occupancy periods, separate the supply air fan power, which
is the kW to use, from the RTU power. This allows design teams to
take credit for using high efficient HVAC systems (low kW/CFM).<o:p></o:p></span></p>

<b>Subject:</b> [Equest-users] Appendix G Fan Simulation<br>
</span><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'><br>
I've seen multiple posts regarding 2004 Appendix G Fan Power and one post from
Ming Zeng suggested the following:<br>
"Baseline model fan usually gives 0.00078KW/cfm. For proposed fans,
typically it is 0.00016-0.00018 KW/cfm/in static*"*<br>
<br>
I have two problems related to this because my Baseline KW/cfm is closer to
0.001 KW/cfm for a bunch of unitary Type-3 systems, which is indefinitely way
too high.<br>
<br>
FIRST<br>
Many people have referred to the calculated fan power as an allowance, which to
me, would appear to be a threshold not to exceed based on the 20deg-F delta for
Appendix G Fan Sizing. I figure this is not the case because others refer to
the fan power as something that is simulated in the model as a KW/cfm.<br>
I've also seen posts where numbers are expressed as KW/kcfm, which would
indicate fan power KW per thousand cfm; which again is not an applicable figure
for simulation using eQuest.<br>
<br>
SECOND<br>
I'm struggling with these items because a recent GBCI reviewer has asked me to
re-calculate my fan power because my BHPs are a bit higher than they should be.
When I "re-calculate" these values I do not come up with the numbers
they do (BHP ASHRAE - attached).<br>
<br>
I'm trying to reconcile my response and eQuest inputs before we re-submit, but
I'm not sure what to do.<br>
<br>
Much thanks.<br>
