[TRNSYS-users] Mean Radiant Temperature More Extreme than Individual Surface Temps



Hello,

I am seeing poor thermal comfort and found that the mean radiant temperature of my air node is more extreme than the inside surface temperature of any individual wall or window comprising the airnode. It is much colder in the winter and much warmer in the summer. 

This doesn't seem possible to me. Any idea what could cause this? Please see first the aggregate temperature range for all walls and windows, and then the mean radiant temperature for the same time period in the two respective graphs below. Thanks.
