Washington – The US states of Arkansas and Maryland have adopted the efficient building energy codes set out by the International Code Council (ICC)
The organisation’s International Energy Conservation Code (IECC) is updated every three years as part of a collaborative process involving energy-efficiency professionals, homebuilders and building officials.
The most recent edition of the international model code is the 2015 IECC and if a state wishes to adopt a code set out by the organisation it can choose to conform to those set out in 2006, 2009, 2012 – with the latest version - IECC 2015 - being the most progressive in terms of energy-efficiency.
Arkansas adopted the 2009 IECC code, which means buildings will have, on average, 11.3% lower energy costs than the previous edition of the code. Maryland adopted the latest code, the 2015 IECC.
The two states' adoption of the codes became effective on 1 January, 2015.
