[Bldg-sim] Climate change-modified simulation weather files

[Matthias Haase]

Dear Joe,

thanks for letting us know about these future weather files. They might be
really helpful. Do you have a reference for the methodology you used to
generate these scenarios?

In addition, do you or does anyone from this list know about work that has
been done on collecting different regulations that require the use of such
weather files to "future-proof" building design (code compliance)?

Best wishes
