<div class="WordSection1">
<p class="MsoNormal">Not to be difficult, but one doesn’t need to look very far back in the news cycle to see that it *<b>only</b>* takes a federal shutdown to back up airports so badly that yeah, probably every space ends up at/beyond designed peak occupancy
at the same time.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m bringing up this to illustrate that you need to bound and explain for yourself (first) what you are trying to get out of this building energy simulation. Is this a historically calibrated to bills model or a future projection? For
an existing building or new construction? Are the model outputs leveraged to put a certification/plaque on the wall or to construct an energy savings performance contract guarantee?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The most “ideal” set of schedules I can imagine would be built not on occupancy rates alone, but instead upon a trended record of (calibrated) return air CO2 sensor readings at the same or a substantially similar airport, for multiple systems/spaces.
This data would be interpreted by the modeler after seeking a detailed understanding of how (for *<b>your</b>* building vs the measured case) the outputs of those sensors will be actually sequenced/commissioned to determine and deliver the outside air flow
as designed. THEN you would factor your schedules up/down to consider the relative contextual variables (like projected passenger loads, city population, etc) appropriate to the purpose of your model…<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">… but that’s going down a path that is probably a step too far for most building energy models. If it’s just for LEED or code compliance you quite likely could just make something up. Just depends on the AHJ/reviewers that may be involved
(asking your AHJ ahead of your own deadlines is never an expressly *<b>bad</b>* idea, by the way). You might also, or minimally, want to do a cursory literature review to found your own assumptions on (i.e. google “airport occupancy rates model”). You can
rest assured that other energy modelers have tackled airports and these specific questions before – with some luck you’ll find someone proud enough of their work (or otherwise funded/paid, or tied to the pursuit of a post-graduate degree) to share their findings
in publication.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m sorry this isn’t much more specific – I have not modeled an airport yet, specifically… but I hope this perspective helps you to define and arrive at your finish line!<o:p></o:p></p>
