Guidelines for Participating in the DOE Challenge Home
The DOE Challenge Home is a new and compelling way to recognize builders for their leadership in increasing energy efficiency, improving indoor air quality, and making homes zero net-energy ready.
The program builds upon the comprehensive building science requirements of ENERGY STAR® for Homes Version 3, along with proven Building America innovations and best practices. Other special attribute programs are incorporated to help builders reach unparalleled levels of performance with homes designed to last hundreds of years.
DOE Challenge Homes are verified by a qualified third-party and are at least 40%-50% more energy efficient than a typical new home. This generally corresponds to a Home Energy Rating System (HERS) Index Score in the low- to mid-50s, depending on the size of the home and region in which it is built.
Challenge Home Requirements
- Comply with ENERGY STAR for Homes and the Inspection Checklists for
- Thermal Enclosure
- HVAC Quality Installation (Contractor and HERS Rater)
- Water Management
- The target home/size adjustment factor used by ENERGY STAR
- Help improve indoor air quality by complying with substantial requirements in EPA's Indoor airPLUS checklist
- Feature energy efficient appliances and fixtures that are ENERGY STAR qualified.
- Use high-performance windows that meet ENERGY STAR specifications.
- Meet 2012 International Energy Conservation Code levels for insulation.
- Follow the latest proven research recommendations by installing ducts in conditioned space.
- Conserve water and energy through an efficient hot water distribution system that provides rapid hot water to the homeowner.
- Accomplish savings on the cost of future solar installations by following provisions from the Consolidated Renewable Energy Ready Home (RERH) checklist for climates with significant solar insolation. This checklist references EPA's solar electric guide and the solar thermal systems guide. Third-party Verifiers must submit DOE Challenge Home Performance Path ratings to the RESNET National Buildings Registry.
DOE Challenge Home Builders are encouraged to:
Commit to constructing 100% of your homes to the U.S. DOE's Challenge Home Requirements.
Minimize water use by participating in the EPA WaterSense for New Single-Family Homes program.
Fortified for Safer Living
Embrace disaster resistance by following the Institute for Business and Home Safety (IBHS) FORTIFIED for Safer Living or FORTIFIED Home provisions for regionally specific natural hazards.
Quality Management Program
Implement comprehensive quality management practices.
Ask buyers to sign a waiver allowing DOE Challenge Home access to one year of utility bill data.
Qualify Homes to Meet the Challenge
Builders can follow two different paths in qualifying a home for the DOE Challenge Home initiative.
To use the prescriptive path, follow the DOE Challenge Home National Program Requirements. A registered verifier should submit the prescriptive compliance report after verification that the home meets the challenge.
Registered verifiers can now use REM/Rate V14 and EnergyGauge USA 3.1.00 to qualify homes to meet the DOE Challenge Home. The software will create a DOE Certificate specific to the certified home.
IMPORTANT: Raters must email the DOE Challenge Home Verification Summary report to firstname.lastname@example.org for builder recognition in the DOE Challenge Home program and on the locator tool.
State energy codes that exceed this program's requirements always take precedence to determine compliance. In states where the residential provisions of the 2012 International Energy Conservation Code (IECC) have been adopted, and are therefore equivalent to some DOE Challenge Home requirements, the mandatory requirements will be updated to reflect the 2015 IECC within six months of the new code's publication date. DOE will maintain a list of state-specific compliance requirements and timelines on this webpage. In the following cases, there are additional state-specific requirements:
Washington State Requirements
To continue adding value beyond code, while including ENERGY STAR Northwest, we now have specific requirements for homes certified in Washington State. This customized program for Washington helps leading builders continue to differentiate their homes in a very competitive market. For homes permitted after January 1, 2014, the Washington DOE Challenge Home Requirements apply.
Following a public review, DOE established California DOE Challenge Home Requirements, which go into effect for homes permitted after January 1, 2014. Given California's advanced energy code and ENERGY STAR program, the requirements include additional mandatory features, but allow for compliance flexibility. Builders certifying homes in California have the option of prescriptive compliance, a performance option using national HERS software, or one of two performance options using California Title 24 compliance software.
The DOE Challenge Home Policy Record contains a description of 1) issues that have been received and resolved since the release of the last revision of the National Program Requirements, and 2) program updates which have been implemented by DOE but did not result in direct changes to the DOE Challenge Home National Program Requirements document.
The rationale for the DOE Challenge Home program requirements are:
- Sound science
- Sound data to back-up provisions
- Widespread availability of required products/systems
- Reasonable adaptability to typical builder practices
Draft requirements were published for public review and comment, and responses were viewed through this framework. In response to these comments multiple changes were made to the final requirements. Interested parties can review DOE's responses to public comments.
