HERS Homes in Treasure Valley, Idaho

HERS Modeled Home

Build A Better, More Energy Efficient Home with The HERS Model

HERS Modeling Process... Step by Step

  • Home Energy Evaluations

    Plan Review

    Please send plans to matt@momentumidaho.com

  • Inspections at Framing Stage

    Rough-In Inspection

    • Perform duct blaster – determines that duct leakage falls within required parameters
    • Inspect energy seal – ensure all penetrations are caulked and/or foam filled

    Building Envelope Inspection

    • Verify correct R-Values
    • Check for gaps and voids
    • Confirm that cavities have been filled with insulation
    • Verify window qualifications – backer rod, U-factor under.30
  • Final Inspection

    Envelope, HVAC & Lighting (right before final clean)

    • Verify furnace qualifications and filtering system
    • Check required attic insulation is installed properly
    • Check crawl space – insulation and vapor barrier installed properly
    • Verify heat pump meets HSPF & SEER (AC SEER Only) requirements
    • Verify water heater efficient factor of at least .61 gas / .93 electric
    • Verify 80% of the lighting is ENERGY STAR
    • Perform blower door test
    • If additional inspections are required, Momentum will notify builder as soon as possible.

HERS Modeling building process

As part of the HERS Modeling building process, Momentum starts with a review of the project’s plans and Manual J to determine a preliminary HERS Score. Momentum’s modeling process is based on the HERS Index, utilizing the RESNET Accredited Rating Software to calculate a rating score on the HERS Index.

During the building process for a HERS-Modeled Home, Momentum is on-site conducting tests at the framing stage such as a duct blaster test, air seal, and insulation inspection. When the home is finished, a blower door test will be conducted along with other inspections such as reviewing attics, crawls, lights, appliances, water run-off and balancing of the HVAC system, if required.

Finally, once Momentum has finalized the home, we input the final numbers into REMrate software to produce the home’s final HERS score. Momentum will then issue the builder a HERS Modeling Certificate.


The lower the score on the HERS Index, the BETTER! The lower the score, the more energy-efficient the home and the less the homeowner will pay in energy bills. LOWER IS BETTER with the HERS Index.
