The Energy Department recently released a new methodology for evaluating homeowner savings through residential energy codes. These codes are commonly adopted by states and local code enforcement jurisdictions across the nation to make homes more efficient and cheaper to power. DOE's new approach is based on a life-cycle analysis that balances initial costs with the longer-term savings these codes make possible. By demonstrating savings available to homeowners, this methodology will aid the adoption of cost-effective, energy-saving codes for residential buildings, and help families save money over the lifetime of their home.
