color:#1F497D'>The ASHRAE-55 Thermal Comfort Tool created by the UC Berkeley
Center for the Built Environment and available from ASHRAE publications (if I
recall correctly) includes a very easy-to-use MRT calculator for rectangular
rooms. It allows for MRT at a particular position in that room, separate
surface temperatures and dimensions for surfaces, and also the inclusion of a “panel”
or other area within one of the walls (such as a cold/hot window, heating panel,
etc.) that has a distinct temperature. This is part of a very handy tool for
determining PPD, etc. based upon the typical range of human thermal comfort
variables (clo value, activity level, air temp, MRT, humidity, air movement).<o:p></o:p></span></p>

<p class=MsoNormal>Hello,<br>
<br>
Is anyone aware of a simple Mean Radiant Temperature calculation tool?
I'm looking for something that will calculate MRT for a basic rectangular room.<br>
<br>
Thanks!<br>
<br>
