【 摘 要 】

The 2012 International Energy Conservation Code (IECC) yields positive benefits for Idaho homeowners. Moving to the 2012 IECC from the 2009 IECC is cost-effective over a 30-year life cycle. On average, Idaho homeowners will save $4,057 with the 2012 IECC. Each year, the reduction to energy bills will significantly exceed increased mortgage costs. After accounting for up-front 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 $285 for the 2012 IECC.
