IECC Climate Zones

HOMER Logo

A Climate Zone Map can be found in the 2012 International Energy Conservation Code (IECC), funded by the U.S. Department of Energy- Energy Efficiency and Renewable Energy.

For each county in the United States, the IECC defines a climate zone.

Locations set within the US will be matched with the closest available location in the OpenEI database with the same climate zone.

The colors of the drop-down menu for climate zones corresponds to the colors in the image above.

The letters following the numerical climate zone correspond to:

A	Moist
B	Dry
C	Marine
