2015 IECC Update

In July 2015 the Hawaii State Building Code Council (SBCC) unanimously approved the 2015 International Energy Conservation Code (IECC) with amendments. The code sets energy efficiency requirements for both residential and commercial buildings.

Following SBCC adoption, the state followed the Administrative Rule path to state adoption and the counties followed the County Council path to county adoption. The Administrative Rule path involved approval by the Attorney General, review by the Legislative Review Board, and approval by the Small Business Regulatory Review Board which occurred on December 8, 2016. In 2017 SBCC voted to cease following the Administrative Rule process. Instead, once the SBCC adopts or amends a code the counties then adopt the code as is or with county amendments.

The county path involves review by the Corporation Councils followed by County Council hearings, amendments, adoption, and approval by the mayors. The code is then enforced via the plan checking and site inspection process.
