The 2009 and 2012 International Energy Conservation Codes (IECC) yield positive benefits for Arkansas homeowners. Moving to either the 2009 or 2012 IECC from the 2006 IECC is cost effective over a 30-year life cycle. On average, Arkansas homeowners will save $1,948 over 30 years under the 2009 IECC, with savings still higher at $6,679 with the 2012 IECC. After accounting for upfront costs and additional costs financed in the mortgage, homeowners should see net positive cash flows (i.e., cumulative savings exceeding cumulative cash outlays) in 2 years for the 2009 and 1 year for the 2012 IECC. Average annual energy savings are $147 for the 2009 IECC and $466 for the 2012 IECC.
