<p>Hello Zane,</p>
<p> </p>
<p>I'd suggest you keep the model as simple as possible, before chasing after design details that have less than a 10% effect. In the following, somewhat dated paper you'll find information about modeling of an entire recreation center with DOE-2, that was
calibrated to on-site energy use: </p>

<p>In general, in large facilities, like gyms, where there is a lot of outside air for ventilation purposes, most of the loads associated with the building will be involved in heating/cooling the fresh air. If the gyms are part of a larger facility, like a
Rec Center, then other issues tend to overwhelm the energy use, for example, swimming pools, ice rinks, laundry facilities, ice melting (i.e., for winter-time), etc.
</p>
<p> </p>
<p>In the case of the Rec Center at CU, we eventually learned enough about the building to predict its energy use and even write an expert system that also predicted what problems were possibly occuring and what might be causing them. Details can be found in
the also somewhat dated paper: </p>

<div dir="ltr">Hi, guys.<br>
I got a project that need to calculate cooling and heating energy of a gymnasium.<br>
And here I have two questions to ask for comment.<br>
<br>
1. The form of object is not a typical one.<br>
It has inclined curtain wall with some louver on it, <br>
and the roof was designed into streamline shape, the height of central section is lower than two side.<br>
Is it possible to build the model like object form or need to simplify? <br>
If need to simplify, what kind of method do you think is the best one?<br>
<br>
2. The under-seat air supply system adopted in the auditorium area.<br>
But as you know, the temperature in large space is different by the height.<br>
So, is it need to separate several zone by height and temperature or just one big zone is ok?<br>
<br>
Looking forward your reply.<br>
Thanks very much!!<br>
<br>
- Zane<br>
