Pre-2015 IECC

The adoption of the 2006 International Energy Conservation Code (IECC) marked a dramatic improvement in energy code quality.  The prior energy code, adopted in 1994, was in response to the National Energy Policy Act of 1992.  The residential section had few requirements and the commercial building requirements were based on the 1989  American Society of Heating, Ventilating and Air Conditioning Engineers (ASHRAE) standards.

The International Codes Council  (ICC) was formed in  the late 1990s and published the 2003 code with a strong residential component. The ICC has since revised building codes on three-year cycles.

In 2007 the Hawaii State legislature formed the Hawaii Building Code Council to align Hawaii with ICC’s policy of updating building codes every three years.  The 2006 IECC, amended to suit Hawaii’s unique climate, was adopted in 2009.

In the ensuing years, the Hawaii Building Code Council improved the national 2009 IECC and it was approved by the Council.  However, the adoption process was not undertaken as no funds to hire staff were appropriated.
