【 摘 要 】

The 2009 International Energy Conservation Code (IECC) contains several major improvements in energy efficiency over the 2006 IECC and the 2003 IECC. The notable changes are: (1) Improved duct sealing verified by testing the duct system; (2) Increased duct insulation; (3) Improvement of window U-factors from 0.40 to 0.35; and (4) Efficient lighting requirements. An analysis of these changes resulted in estimated annual energy cost savings of $145 a year for an average new house compared to the 2003 IECC. This energy cost saving decreases to $125 a year for the 2009 IECC compared to the 2006 IECC. Construction cost increases (per home) for complying with the 2009 IECC are estimated at $1256 relative to the 2003 IECC and $800 for 2006 IECC. Home owners will experience an annual cost savings of about $80 a year by complying with the 2009 IECC because reduction to energy bills will more than compensate for increased mortgage payments and other costs.
