Antw: [EnergyPlus_Support] window surface temperature

["Achim Geissler" <Achim.Geissler@xxxxxxxxxxxxxxxx>]

Alan,

as first idea: Check your long wave radiation surrounding. Indoor will
have eps of approx 0.9, probably and a surface temperature of ??.
Outdoor long wave radiation temperature will be around air temperature,
probably. Thus, the surface temperature difference of 0.2 K for the
single pane could easily be explained.

There is a problem I don't understand. I let E+ report all the 
surface temperatures. I found that in summer condition,  the 
exterior wall inside temperature (35.29 C) is much lower than wall 
outside temperature (53 C ). This makes sense since the wall is 
exposed to sun. However,the window inside temperature (32.8 C) is a 
little bit higher than window outside temperature (32.6). How could 
this be possible? The window is also exposed to sun, should have a 
higher temperature. That is just a single pane window which 
definately on that exterior wall.  

Firstly I doubt that my input might be wrong, but I tried those 
example files and reported surface temperatures. It is same. So 
anyone knows why it is, please let me know. Thanks a lot.

Sincerely,
Alan
