[Bldg-sim] Mapping ASHRAE and Koppen Climate zones

[Joe Huang]

About 10 years ago I needed to get the Koeppen Climate Classification for thousands of 
international locations  in order to run a solar model (Zhang-Huang 2003) where we've 
grouped locations by Koeppen CC.

In order to do that, I found a digital map of the entire world at a half-degree grid with 
the Koeppen CC for each grid, and then wrote a script to read the map file and then return 
the Koeppen CC for any location based on its lat/lon. It worked well enough for my needs 
that after I've added the Koeppen CC to the station information, e.g., lat, lon, elev, 
time-zone, etc., I haven't had a need to return to the map since.

Some words of caution about the Koeppen CC.  Since they're based on a number of climate 
statistics, the Koeppen CC will change for some locations near the boundaries (just like 
ASHRAE Climate Zones!:-)).  I'm not in favor of such shifting climate zones and decided to 
use what somebody has compiled than embark on my own calculations.

I can share more information about what I did if there's interest.
