[EnergyPlus_Support] Re: Surface outside tempearture vs solar radiation.

["Linda Lawrie" <linda@xxxxxxxxxx>]

I have not been able to find any reason (yet) for your problems though 
I believe I verified it.  Our example file with > 4 sides, does not 
exhibit any problems.

I would suggest you try an equivalent area surface for that roof and 
see if that helps.
