We Partner With ENERGY STAR®

  • What is ENERGY STAR®?

    ENERGY STAR is a program run jointly by the Environmental Protection Agency and the Department of Energy to help consumers and business owners reduce energy costs and protect the environment through the installation of certified energy-efficient products.

    ENERGY STAR is the trusted, government-backed symbol for energy efficiency, helping us all save energy, save money and protect the environment through energy-efficient products and practices. The ENERGY STAR label was established to eliminate the need for additional power generation plants, reduce greenhouse gas emissions and make it easy for consumers to identify and purchase energy-efficient products that offer savings on energy bills without sacrificing performance, features and comfort.

  • How does the EPA choose which products earn the ENERGY STAR® label?

    Products can earn the ENERGY STAR label by meeting the energy-efficiency requirements set forth in ENERGY STAR product specifications. The EPA establishes these specifications based on the following set of key guiding principles:

    • Product categories must contribute significant energy savings nationwide.
    • Certified products must deliver the features and performance demanded by consumers, in addition to increased energy efficiency.
    • If the certified product costs more than a conventional, less-efficient counterpart, purchasers will recover their investment in increased energy efficiency through utility bill savings within a reasonable period of time.
    • Energy efficiency can be achieved through broadly available, non-proprietary technologies offered by more than one manufacturer.
    • Product energy consumption and performance can be measured and verified with testing.
    • Labeling effectively differentiates products and is visible to purchasers.

    ENERGY STAR specifications are revised periodically to ensure relevancy under current market conditions. The EPA strives to make certain that specifications differentiate the most efficient products.

Rebates: Appliances & Lighting

  • Does LED lighting save more energy than incandescent lighting?

    Yes, ENERGY STAR® certified LED bulbs will consume up to 90 percent less energy than the equivalent incandescent bulb. They will also last at least 15 times longer and could produce up to $230 in savings as compared to incandescent over the lifetime of the bulb.

  • How do I apply for appliance and lighting rebates?

    You can apply for appliance rebates by mail, or online at by going to “Rebates” and clicking on the purchased item or energy improvement. Most LED bulbs are instantly marked down by our rebates at specific participating retail locations; no rebate forms need to be filled out.

  • How can I track the status of my appliance rebate?

    Rebates will be processed within four to six weeks of receipt of the application. For ENERGY STAR® appliances, please contact EFI at 877-647-2833 to get a status update or email For other programs, please contact your Utility Partner.

Home Audits & Weatherization

  • How do I apply for weatherization rebates that are recommended for my home?

    Customers who initially qualify for the Home Performance with ENERGY STAR® program can fill out the enrollment form online and file it electronically.

  • What is the Home Heating Index (HHI) tool?

    The Home Heating Index (HHI) tool is part of the NHSaves Audits and Weatherization Program, which can be found at The tool helps customers determine if their home qualifies for an audit that can ultimately help them earn energy-efficiency incentives and rebates. Meaningful incentives, established contractor relationships and access to low-interest financing contribute to savings of up to $8,000 on overall improvement costs. Through enhanced weatherization tactics, customers save on all of their energy use, including oil, propane and wood heating fuels.

  • How does the Home Heating Index (HHI) tool work?

    The HHI tool identifies homes with high energy use per square foot. Using the on-line tool, customers simply plug in their heating usage over one year, the square footage of their home, utility provider and zip code. Customers are then provided with a heating index of their home’s energy efficiency.

  • How are my energy efficiency recommendations determined?

    A certified home energy auditor will perform a comprehensive assessment of the home’s energy efficiency. The assessment is an energy and safety evaluation of the home that includes a visual inspection of lighting and appliances, as well as performance testing of the ventilation and mechanical systems, building tightness and insulation levels that will result in recommended energy efficiency improvements. Based on recommendations made by the auditor, you may be eligible for a 50 percent rebate of up to $4,000 to help you pay for these improvements.

  • What takes place during an energy audit?

    During a home energy assessment, a specialist will evaluate the entire property using the standards developed by the Building Performance Institute (BPI) as a guideline. Included in the assessment will be the heating, cooling and water heating systems, the amount of insulation, the types of lighting being used and the efficiency of the appliances. The auditor will conduct diagnostic tests throughout the entire home, including the attic and basement, windows and duct work to detect areas that are susceptible to air leakage. The homeowner is provided with a detailed report with recommendations on how the home’s energy efficiency can be improved, including sealing leaks, adding insulation, ensuring ducts are properly connected and upgrading lighting, appliances, water and heating and cooling systems.

  • How does HERS work and why is it valuable?

    The Home Energy Rating System (HERS) index tells you how efficiently your new home will operate. According to the U.S. Department of Energy, a home with a HERS index score of 70 is 30 percent more efficient than a standard new home, while a home with a score of 130 is 30 percent less efficient. A lower HERS index can command a higher price when selling your home.

  • What are the qualifications of the Energy Specialist who will complete my home energy assessment?

    The Building Performance Institute (BPI) certifies all NHSaves energy specialists. The BPI provides credentialing, assures high quality and sets standards for home performance professionals. In order to receive certification from the BPI, contractors must pass written and field exams and be capable of assessing opportunities for enhanced energy efficiency through the use of state-of-the-art diagnostic tools.

  • How is pricing set for work done to a home as part of a NHSaves program?

    The Home Energy Assistance (HEA) and Home Performance with ENERGY STAR® (HPwES) programs use fixed unit pricing for all applicable measures offered through the programs (air sealing, insulation, lighting, etc.).

  • Can I choose my own contractor to install my recommended air sealing and/or insulation work?

    Customers can choose any contractor from our group of qualified HPwES contractors. Unfortunately, contractors who have not been approved by the utilities cannot participate in the HPwES program. A list of our participating contractors can be found on

For Contractors

  • What is the ENERGY STAR® Homes program?

    The ENERGY STAR® Homes program is for new construction and major renovations that are 15 to 30 percent more efficient than standard homes. In order to earn certification, homes must reach a level of performance regarding insulation, windows, heating and cooling equipment, air-tight construction, lighting, appliances and water protection systems. Third-party verification from a certified home energy rater is required to earn ENERGY STAR certification.

  • What is the Net Zero Home Competition?

    This design and build competition awards contractors for building energy-efficient, net zero energy single- and multi-family homes. First prize is $5,000, with second and third place winning $2,000 and $1,000, respectively. Homes must earn the ENERGY STAR® label, be completed and in move-in condition and be located within the service territory of Eversource, Liberty Utilities, New Hampshire Electric Cooperative or Unitil. Homes will be inspected during construction and at completion.

  • How do participating independent installation contractors and home performance contractors qualify to be a part of the NHSaves Program?

    Utility partners work with all contractors involved with installing, designing, selling and supplying energy-efficient products. For more information, contact one of the participating utility companies.
