HERS Ratings:
Trusted Testing for Nantucket Builders

Stephens & Co. is. proud to partner with Nantucket builders, architects, and homeowners, providing specialized Home Energy Rating System (HERS) testing and certification services to achieve code compliance, elevte the homebuilding craft, and deliver homes that stand out for their efficiency and lasting quality.

What Is a HERS Rating?

The HERS Index, established by RESNET (the Residential Energy Services Network), is the nationally recognized standard for measuring a home's energy efficiency. Before permitting, we prepare an energy model based on projected dwelling assemblies, equipment, and appliances. The builder then submits the projected HERS documentation to demonstrate planned compliance with the energy code.

We conduct inspections and collect documentation at both the framing and weathertight shell stage, as well as after insulation and before drywall. Following a thorough final evaluation—including blower door and duct leakage tests—each project receives a score reflecting its overall efficiency. Lower scores indicate better performance.

Why HERS Matters For Builders

  • Code Compliance & Documentation
    Nantucket’s stringent building codes require clear, objective verification of energy performance. A certified HERS rating streamlines the energy inspection process, providing third-party proof that your projects meet or exceed standards.

  • Future-Proofing & Resilience
    High performance isn’t just about passing today's codes. It’s about delivering builds that are comfortable, durable, and prepared for evolving energy standards, climate conditions, and client expectations.

  • Quality Assurance
    A certified HERS Rater independently validates the quality of construction. A good score signals that the home will perform as designed, giving both the builder and future homeowner confidence in energy efficiency and overall home quality.

  • Competitive Differentiation
    Builders who deliver low HERS scores demonstrate both technical expertise and a commitment to higher-performance construction—a key advantage as buyers increasingly seek efficient, resilient homes.

  • Access to Incentives & Certifications
    HERS-rated homes often qualify for valuable rebates, and financing benefits. Builders use HERS scores to meet requirements for programs like ENERGY STAR for Homes and Apartments, Passive House Certification, and utility incentives.

  • Cost Savings for Clients
    Homes with lower HERS ratings ensure lower utility bills and increased comfort, offering lasting value to homeowners—a powerful selling point for any builder.

  • Easy Process, Clear Communication
    We coordinate directly with your team–on-site and in the office–to keep your projects on track and on schedule, minimizing delays and paperwork
