[Bldg-sim] Mapping ASHRAE and Koppen Climate zones

Not exactly a mapping, but ASHRAE Standard 169-2013 and 90.1-2019 have tables that show ASHRAE climate zones for international locations.

I found this paper from Purdue about evaluating European climate zones:

If you have a table compiled of the Koppen perhaps you can compare. It may not be 1:1 on the mapping since ASHRAE uses CDD/HDD and humidity and it appears that Koppen includes some seasonal variance in their categorization.

Here’s a sample for UK from 90.1-2019 – it appears to only show “A” side and none in B/C humidity zones for the UK. I do see some B/C in the other countries so it must be considered at some level.

Hi all,

Does anyone know if there's a mapping that links a Koppen climate classification with an ASHRAE climate zone classification?

I haven't been able to find anything with my 5 min google search!!

Thanks for any help folks can provide!
