<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>EnergyPlus gives you a greater
understanding of comfort by allowing you to output every surface temperature
and checking the numbers to make sure asymmetric thermal discomfort doesn’t
occur. It also outputs PMV and PPD as well as several other more recent
comfort models to give you a better understanding of meeting the criteria
established in ASHRAE 55. <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Also, EnergyPlus allows you to specify a
particular surface that an occupant is closest to such as a floor in a large
warehouse or a window surface in a perimeter office space so that its
temperature has greater weighting in the PMV calculation. If you really want
to get detailed, look into the free comfort program provided by the “Center
for the Built Environment” which will create a PMV chart across the floor
surface due to different view factors and thermal asymmetry. It has a user
interface. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Finally, my company has a program called
ROOM that analyzes a thermally complex room such as a naturally ventilated
atrium space and quickly does all these processes in one program. It combines
a lot of the steps needed to do thermal analysis as well as understanding
comfort in one packaged program. It is available for purchase. Email me if
you are interested. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>As Vikram mentioned, RadSim may be a
program which can provide the analysis you need. I’ve heard of it but
have never used it. I think its free which is always a bonus. I’d be
interested to hear how it works.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=blue face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:blue'>If your doing PMV calcs, I'm not sure any
of the current energy simulation models (energyplus, equest, trace etc) are a
good choice. They are lumped node models, and as such average zone temperatures
and surface temperatures. Things like MRT depend so much on what position in
the room your in. For instance in a 100 ft x 100ft room if you have a west
glass facade, with interior walls around it, your PMV 5 feet away from the
facade is going to be radically different than that 90 feet away. I would also
caution about averaging these values. If you have one end of your room that's
too cold, and another that's too hot, your answer will be that every one is
comfortable, when in reality no one is. </span></font><o:p></o:p></p>

<p class=MsoNormal><font size=2 color=blue face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:blue'>If your going to be basing a lot of design
decisions on this study, I would recommend using a full field solution (like
CFD or RadTherm) that will allow you to look at sample MRTs at different points
in the room. </span></font><o:p></o:p></p>
