The added mortgage costs will be o�set by monthly energy savings of $15, helping homebuyers pay o� their initial investment in only forty four months. After breaking even during this time, the home will return buyers a pro�t of at least $12 per month—for a total return of about $150 every year. This return on investment is shown in balance sheet below.
For the average new home, the 2012 IECC will only increase construction costs by a total of $1,847. When this amount is rolled into the average mortgage, real costs to homebuyers will mean a down payment increase of only $270, and $7 extra on monthly mortgage bills.

This model assumes a 2,400 square foot home. The mortgage is conservatively set at 30 years, with 20% down and the current average nationwide interest rate of 4.03%. With a lower down payment—such as 10%? down—consumers will break even on their investment even sooner.

Homes are the biggest investment we make—and everyone deserves a home that meets national minimum energy e�ciency standards. While it’s true that homeowners can always improve the e�ciency of their homes, it is far more cost-e�ective to upgrade building components during construction, putting in better windows or swapping out one grade of insulation for a better one. Here’s what buyers get with the 2012 IECC:
