【 摘 要 】

The 2009 and 2012 International Energy Conservation Codes (IECC) yield positive benefits for Minnesota homeowners. Moving to either the 2009 or 2012 IECC from the current Minnesota Residential Energy Code is cost effective over a 30-year life cycle. On average, Minnesota homeowners will save $1,277 over 30 years under the 2009 IECC, with savings still higher at $9,873 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 exceed cumulative cash outlays) in 3 years for the 2009 IECC and 1 year for the 2012 IECC. Average annual energy savings are $122 for the 2009 IECC and $669 for the 2012 IECC.
