When you’re inputting your project’s zip code, the DDx will automatically generate the project’s climate zone (See Choose Climate Zone page), for U.S. based projects. Note: the DDx will run an error if your entering a zip code but choosing the incorrect state in the Project State dropdown (see screenshot below).
For a full list of the zip codes and the associated states in the DDx, please see . If the zip code you’re entering is running an error, please let us know at 2030Commitment@aia.org and choose a neighboring zip code.
