[Radiance-general] What to do when no Weather File is available?

[CHI-German Molina]

Thanks Raphael and Jan,

I assume Meteonorm would be the best source of information for these kind
of cases. However; is that data representative enough to use it for design
just as if it were a measured data? Should we take anything special into
account?

THANKS!
