Wisconsin Energy and Cost Savings for New Single- and Multifamily Homes: 2009 and 2012 IECC as Compared to the Wisconsin Uniform Dwelling Code.

摘要

The 2009 and 2012 International Energy Conservation Codes (IECC) yield positive benefits for Wisconsin homeowners. Moving to either the 2009 or 2012 IECC from the current Wisconsin state code is cost effective over a 30-year life cycle. On average, Wisconsin homeowners will save $2,484 over 30 years under the 2009 IECC, with savings still higher at $10,733 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 1 year for both the 2009 and 2012 IECC. Average annual energy savings are $149 for the 2009 IECC and $672 for the 2012 IECC.
