<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">I never knew that the MRT calculation would require Globe Temp. My understanding of this is that the Globe Temperature is actually a function of Air Temp,
MRT and the convection (air speed effects.) The MRT is calculable from the temperature of the surrounding surfaces. If the Op Temp calculation includes air temp, MRT, RH, and air speed, then there is no need to ever know Globe Temp. Opinions here, maybe
not facts!<o:p></o:p></span></p>

</div>
<div>
<p class="MsoNormal">For EQc7.1 in LEED NC 2009, I need to provide detailed calculations for "operative temperature".
<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">ASHRAE 55 appendix C gives you the formula to calculate operative temperature, but that requires mean radiant temperature. And the formula for "mean radiant temperature" requires globe temperature.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">I am trying to find a graph/chart/table from which I can obtain the "globe temperature" or do I even need to find globe temperature ?<o:p></o:p></p>
