[EnergyPlus_Support] Re: COMIS & window transmitted solar

["leeslwong" <bclwong@xxxxxxxxxxxx>]

Mike,

If I want to the result of the mean air temperature of the room with 
ventilation and solar heat effect which is the real case I think, so 
that I 
should change the solar transmittance of the glass to 0.9999. Then, 
the 
temperature and the rate of thermal comfort will become more 
realistic 
situation of the room. Is it the correct way I can do?
