Re: [EnergyPlus_Support] TMY2 Weather Files for E+



The main advantage of TMY3 is that they are available at many more sites 
than TMY2.  But at common sites, I would not quality TMY3 as "better" 
than TMY2 without further investigation. There is a number of things at 
play here, including very different methodologies in the underlying met 
and radiation data, different assumptions and limitations, etc. There 
are sites where TMY2 is most probably "better" than TMY3. I strongly 
recommend not to dump TMY2 until this is all sorted out.
