National average energy savings against a 2006 IECC baseline:
• The 2009 IECC saves 10.8% of energy spent for heating, cooling, water heating, and lighting
• The 2012 IECC saves 32.1%
Long-term cost-effectiveness for consumers:
• Life-cycle cost savings over a 30-year period, averaged across all building types and configurations, are significant in all climate zones
• Average consumer savings range from $1,944 in Climate Zone 3, to $9,147 in Climate Zone 8 when
comparing the 2009 IECC to the 2006 IECC
• Life-cycle cost savings for the 2012 IECC, as compared with the 2009 IECC average $2,280 in Climate Zone 2 and up to $23,900 in Climate Zone 8
• When comparing the 2012 and 2006 IECC, life-cycle costs savings average $4,763 in Climate Zone 2 and $33,105 in Climate Zone 8
