<p class=MsoNormal><span style='color:#1F497D'>As an extra suggestion, you can
take the approach Bill is describing but instead define the ventilation systems
as a direct load on a sub-meter to your default electric meter. The
advantage to this extra step is you can reference report PS-B to more easily document
the garage ventilation system demand/consumption on the EAp2 template as a
process load separate from your other “misc. equip” loads, the same
way elevators get a separate line. My last reviewer demanded this be
broken out separately.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>Attached discussion describes
the suggestion more thoroughly.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>To my knowledge nobody has yet
put forth a “standard” or “baseline” schedule to use
for garage ventilation, so I’ve always resolved to model them identically
thus far. <o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>From discussions with various others,
I understand CO/CO2-sensored systems don’t operate terribly often, even
in busy garages. I suspect the predominance of modern catalytic
converters (fewer cars from the 70’s and earlier are driven daily) has a
lot to do with the ppm values not getting approached.<o:p></o:p></span></p>

a process load (Direct Loads – Interior), with the load equal to the fan
power and with a schedule that approximates when the fan will run based on CO2.
The load and schedule should be identical between your baseline and proposed
unless you can justify it through an exceptional calculation. See Dakota
Kelley’s email, attached.<o:p></o:p></span></p>
