<p class=MsoNormal style='margin-bottom:12.0pt'><span style='font-family:"Arial","sans-serif"'>Here’s
a question about Demand Controlled Ventilation in eQuest. I’m
trying to justify a model I built that uses critical zone DCV. In the
past I’ve simply trusted that eQuest calculates this properly but now I
find myself having to provide backup rationale to the USGBC.<br>
<br>
In Volume 6 of the documentation it states: “Each zone OA requirement is
calculated based upon the hourly maximum of either OA-CFM/PER (times the
NUMBER-OF-PEOPLE adjusted by the hourly PEOPLE-SCHEDULE) or a minimum OA
ventilation rate.” However, “OA-CFM/PER” is never
defined in any other dictionary, at least not in any manner that would tell you
how to change or input this variable (it is referenced elsewhere). I
think this is a typo. I think the sentence should refer to
“OA-FLOW/PER”, which is a perfectly transparent and well-behaved
user input (so far as I know).<br>
<br>
Anyone run across this before? Can anyone confirm that Volume 6 has a
typo?<br>
