True Cost of the 2012 IECC for New Homes in Tennessee Climate Zone 4

Upgrading new homes in Tennessee’s Climate Zone 4 to the 2012 International Energy Conservation Code (IECC) will reduce out-of-pocket expenses for homeowners – paying off their initial investment in a matter of months.

For the average new home, the 2012 IECC will only increase construction costs by a total of $2,344. When this amount is rolled into the average mortgage, real costs to homebuyers will mean a down payment increase of only $469, and $9 extra on monthly mortgage bills.

The added mortgage costs will be offset by monthly energy savings of $23, helping homebuyers pay off their initial investment in only 34 months. After breaking even during this time, the home will return buyers a profit of at least $14 per month – for a total return of $163 every year.
