Yes, we have. We used CONTAM, which is a bulk air flow modeling tool
available from NIST (<a class="moz-txt-link-abbreviated" href="http://www.nist.gov">www.nist.gov</a>) coupled with TRNSYS . TRNSYS did the
thermal model and CONTAM did the interzonal air flows. If your building
model is a single zone, however, I don't think CONTAM or other bulk air
flow models (such as COMIS) will be appropriate, however. Bulk air flow
models define pressure nodes (much like the thermal zones of a
building) and predict air flow between those nodes based on the
resistance offered by gaps around doors, the porosity of building
materials, joints between walls, window frames, operable windows,
etc.). If you are just dealing with one large space then the internal
resistance to air flow is quite low and you would probably need to use
a CFD tool such as Fluent to get at it.<br>
Kind regards,<br>

<br>
has anyone completed a "macroscopic multi-zone, analytic
model that predicts room-b-room outdoor air flow rates" for LEED NC 2.2
EQ credit 2? What software did you use? I'm actually evaluating just
one large space for my current project.<br>
<br>
Any help is appreciated.<br>
<br>
Thanks,<br clear="all">
