Peter,
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.
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.

Subject: [BLDG-SIM] Zone mean radiant temperature in eQuest
Does anyone know of a way to extract zone mean radiant temperature (or
surface temperatures) on an hourly basis from eQuest? We are looking for
this data in order to do an annual PMV calculation.
Thanks,
Peter
