Hi Arpan,<br>
<br>
The CBE thermal comfort model can do this but may not be generally
available.
<a class="moz-txt-link-freetext" href="http://www.cbe.berkeley.edu/research/briefs-thermmodel.htm">http://www.cbe.berkeley.edu/research/briefs-thermmodel.htm</a><br>
<br>
TRNSYS 17 with the detailed radiation model allows definition of
multiple comfort points in one zone and calculation of local comfort
at each point based on the operative temperature experienced at that
point. Air temperature gradients could be accounted for by defining
a single radiation zone with multiple air zones.<br>
<br>

<div>Are there other tools out there which are specifically
developed to perform only comfort calculations, PMV, PPD, etc.?</div>
<div> </div>
<div>My understanding of the comfort models in DesignBuilder,
ApacheSim other energy modeling engines is that they calculate
comfort only at the central node of each thermal zone. </div>
<div> </div>
<div>Is anyone aware of tools which calculate a gradient of
comfort within each thermal zone?</div>
