On March 27, Idaho Governor Dirk Kempthorne signed a new law requiring local governments that issue building permits and enforce building codes in the state to adopt the International Building Code and the International Energy Conservation Code (IECC) by January 1, 2003. The IECC applies to residential and non-residential construction, and will bring consistent standards to Idaho, in place of the current patchwork of local codes.

DOE Office of Energy Efficiency and Renewable Energy assisted in this upgrade through technical assistance and building code training materials. Pacific Northwest National Laboratory, on behalf of DOE, conducted an economic analysis for the state and estimates that annual energy savings and overall economic benefits will total about $25 million. Idaho has also used BTS State Energy Program Special Project grants to further its energy code upgrades.
