<p class="MsoNormal">When you are in the custom zone screen in the wizard, you can go to the custom zone names button and in there you can select the zone that should act like an "atrium".<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"> <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">The other way to think about modeling atriums is to model them as they are (one floor stacked on top of another) but without an actual floor surface in between. In your model your zones will be assumed to be equal conditioning requirments
so that the floor between the "atrium" spaces is modeled as adiabatic with no thermal exchange between these zones.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"> <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Now you have to remember that DOE2 & eQuest is a STATIC modeling program, it cannot accurate model airflow & exchange between zones to give you a true
<u>thermal</u> analysis of the behavvoiur of the spaces with each other. You can merely "represent" the concept of th design in the model, but it won't be accurate for real life.<o:p></o:p></p>
