<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif";
color:navy'>In this context, “explicitly” means entering a non-zero
value for fan SUPPLY-STATIC or SUPPLY-KW/FLOW when using eQUEST. Most likely
you will be modeling the fan as continuous anyway (per G3.1.2.4) but even if
you model it as cycling you will need a non-zero fan power if you let eQUEST
calculate the EIR. eQUEST converts SEER and EER to EIR which has no fan power,
then adds fan power in the form of SUPPLY-STATIC. (Someone please correct me if
I’m wrong.)<o:p></o:p></span></p>

color:navy'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif";
color:navy'>Use the G3.1.2.9 equations for your baseline fan power. See
attached for reference. There is a lot of discussion in the archives (try
“SEER EER EIR”) but none that I’d call definitive. I’m
still trying to figure it out.<o:p></o:p></span></p>
