Re: [EnergyPlus_Support] MRT higher than MAT

["Michael J. Witte" <mjwitte@xxxxxxxx>]

It is quite reasonable to see such temperatures.  MRT is a weighted 
average of the inside surface temperatures.  Most likely during mid-
day the roof is hot from the sun, and this will raise the MRT in the 
space.  Because the thermal mass of the surfaces cools more slowly 
than the room air in the evening, the surfaces will be warmer than 
the room air.
