Modeling natural ventilation isn't a very easy task - you need to
link the building thermal model in TRNSYS with an airflow model using
either COMIS 3.2, CONTAM (Type97) or TRNFlow. Each of those represents
an airflow model of the building that determines the amount of ambient
air that will flow into the building due to wind pressure and buoyancy
(temperature and height difference) effects. You would presumably also
have to write a model of a set of windows that open and close between
your 5 and 21 C temperature set points. You might begin by looking at
Type97's mathematical description and at the CONTAM example that is
provided with TRNSYS.<br>
Kind regards,<br>

I am trying to simulate an office room with radiatiors, cool ceeling
and AHU. I want to use natural ventilation whenver is possible ( this
would be between 5 to 21 degrees of external temperature). Could
someone help me with the types that I should use, or a brief idea on
how should I proceed?<br>
Thanks a lot!!<br>
