2009 INTERNATIONAL ENERGY CONSERVATION CODE

FOR NEW HOMES IN

COLORADO

One o the major barriers to energy code adoption across the country is the concern that newcodes will add to the purchase price and potential buyers will not be able to aord the homes

they want. In Colorado, upgrading homes to the 2009 International Energy Conservation

Code will actually reduce out-o-pocket expenses or homeowners – paying o their initial

investment in a matter o months.

For the average new home, BCAP estimates the costs o the new code will add a total o $923

in construction costs—an increase o only 0.3%. When this amount is rolled into the average

mortgage, real costs to homebuyers will mean a down payment increase o $184.55, and

$3.99 extra on monthly mortgage bills.

These added mortgage costs will be oset, however, by monthly energy savings o $19.96,

helping homebuyers pay o their initial investment in only twelve months. Ater breaking

even in month twelve, the home will return buyers a prot o $16 per month—or a total

return o $192 every year. This return on investment is graphed below and presented as a

balance sheet at right.

This model assumes an average sale price of $267,451 for a

2,400 square foot home. The mortgage is conservavely set at

30 years, with 20% down and the current average naonwide

interest rate of 5.05%. 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 efciency standards. While it’s truethat homeowners can always improve the efciency o their homes, it is ar more cost-eective to upgrade building components during construction,

putting in better windows or swapping out one grade o insulation or a better one. Here’s what buyers get with the 2009 IECC:
