The Energy Metrics to Promote Residential Energy Scorecards in States (EMPRESS) is a State Energy Office-led project, supported by funding from the U.S. State Energy Program of the U.S. Department of Energy and private sector partners. The states’ objective in undertaking the project is to advance large-scale home energy labeling, and harmonize various energy scoring programs to better support the market valuation of energy efficient homes. The EMPRESS project is led by the Rhode Island Office of Energy Resources, and includes as project partners the Massachusetts Department of Energy Resources, the Missouri Division of Energy, the Arkansas Energy Office, the Oregon Department of Energy, the National Association of State Energy Officials, Earth Advantage, Energy Futures Group, and Vermont Energy Investment Corporation. 

The EMPRESS Project Team has compiled the project's deliverables into a website ( This website contains case studies, sample legislation, a policy guidebook, recommendations for key label components and much more. 


Goal 1: More closely coordinate the Home Energy Rating System (HERS) and Home Energy Score, so that ratings and performance data are comparable and translatable.

Goal 2: Develop and promote model approaches and programs that encourage the voluntary use of residential energy data.
Goal 3: Educate real estate market stakeholders and other others about the policies, programs, processes, and market-facing information associated with a harmonized approach to home energy labeling.

Harmonization recommendations -- Identify common metrics to harmonize the results of RESNET’s Home Energy Rating System and the Department of Energy’s Home Energy Score. Develop definitions of common elements for an asset based, market-facing home energy label. Explore using a single modeling software platform (such as EnergyPlus) to align HERS and HEScores.

Policy toolkit -- Develop and distribute model polices and examples of legislation and governance frameworks that encourage the voluntary use of residential energy data. Click here to download the completed EMPRESS Final Report
