IECC Climate Zones 1-7 by county
I am very impressed how the IECC clime zone map identified every county having a specific climate zone number 1-7 using the heating/cooling days calculation to determine equivalent areas in the US to categorize as similar climate zones.
I am looking to take this one step further. I am looking to obtain an excel file listing every zip code known the 50 states including Puerto Rico as of 2013 that has the identified IECC climate zone classification number of 1-7. Additionally, if the list can also contain the county and state as well..
Would anyone know if this is available from any organization, group, individual, etc.? Or has any leads as to how to obtain this list?
Thank you,
Tim

Very few counties will have a significant climate zone change between the warmest & coolest ZIP codes within the county, and on most of those it would be due to a dramatic elevation difference, where it's easy to estimate the delta HDD/CDD of the extremes simply by a 3F/1000' approximate adiabatic temperature difference.
SFAIK none of the county-by-county climate zone info used in the IECC is available in spreadsheet format.
Tim,
Older versions of the IECC included county-by-county maps with climate zone information on each county. If you can get your hands on a copy of the 2000 IECC, you can read all the data.
The system was so cumbersome that it was simplified to the current climate zone system, which divides the country into far fewer zones.
Tim,
Get yourself a copy of ResCheck (http://www.energycodes.gov/rescheck), the "counties.dat" file you'll find in its installation folder is a plain text file containing this info (not sure of its source, though), and you should be able to open this with Excel and filter it into columns.
