*A review of the codes in place in jurisdictions across the state indicates that 86% (Hawaii) and 82% (Arizona) of the population is covered by codes at this level.

 

^ When an amendment impacting energy efficiency can be quantified using DOE Prototype Building Models, they were captured in the analysis.

 

Note:

 

  1. A home rule state is one where codes are adopted and enforced at the local level. Some home rule states will have a mandate that jurisdictions can go above code but also have to meet a certain minimum code. In general terms, the idea of home rule is defined as the ability of a local government to act and make policy in all areas that have not been designated to be of statewide interest through general law, state constitutional provisions, or initiatives and referenda.
  2. States with extensively different baseline codes for which conducting custom analysis would be cost prohibitive and out of scope of this analysis.
  3. For states adopting both IECC and 90.1, the IECC code is usually analyzed as the state current code in this study except for states with extensive amendments to the IECC.
