【 摘 要 】

The 2012 International Energy Conservation Code (IECC) yields positive benefits for Iowa homeowners. Moving to the 2012 IECC from the 2009 IECC is cost effective over a 30-year life cycle. On average, Iowa homeowners will save $7,573 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 the 2012 IECC. Average annual energy savings are $454 for the 2012 IECC.
