Lower HERS Scores. Bigger Savings. Smarter Homes.
We Are Certified HERS Raters and Field Raters In Massachusetts & Rhode Island
A HERS Rating can be thought of as a measure of efficiency for new homes. With vehicles, we think in terms of miles per gallon. Similarly, for a new home, performance is measured by a HERS score; the lower the score, the more efficient the home. A passing HERS score of 45 is a requirement when building a new home in Massachusetts. Compare this to the baseline home score of 100.
Our building plans incorporate crucial details about mechanical systems and building envelopes. Our Certified HERS Field Raters, with their boots on the ground, then verify through observation and testing that these crucial details are implemented correctly.
Certified to work as a Qualifying Contractor within the Massave Program, Beauchemin [Bōsh-min] Designs dba Energy Geeks, has successfully implemented HERS Ratings on hundreds of new builds and helped our clients take advantage of often generous incentives and rebates offered by the Massave Program.

Whole-Home Performance, Measured and Verified
What Is a HERS Rating?
A HERS rating evaluates how efficiently a home is designed and built by analyzing the entire building system, including:
• Insulation and airtightness
• Window and door performance
• Heating and cooling systems
• Ventilation and indoor air quality
• Duct leakage
• Renewable energy systems
Lower HERS scores indicate higher efficiency, improved comfort, and reduced energy use.
HERS-Rated for Energy Efficiency
HERS Ratings in Massachusetts & Rhode Island
Energy codes and utility programs throughout New England increasingly rely on HERS performance targets.
• Massachusetts: Stretch Code and Specialized Stretch Code compliance often requires verified HERS scores
• Rhode Island: Energy programs and code pathways frequently use HERS modeling and testing
• New Construction: HERS ratings are commonly required for permitting, rebates, and certifications
Understanding these requirements early helps avoid delays, redesigns, and failed inspections.

From Design Assumptions to Proven Performance
HERS Performance Testing & Verification
HERS ratings rely on verified field testing to confirm that design intent matches construction reality. This typically includes:
• Blower door testing to measure airtightness
• Duct leakage testing (when applicable)
• Final performance verification and reporting
These tests validate energy models, identify leakage issues, and support long-term performance.

Performance Built In, Not Bolted On
Integrated Design + Performance Approach
Unlike standalone testing services, Beauchemin Designs integrates HERS thinking into the design process itself. By coordinating energy modeling, envelope strategies, and mechanical planning early, we help ensure homes are built right the first time.
This approach supports:
• Smoother inspections
• Predictable HERS outcomes
• Better comfort and efficiency
• Reduced risk of late-stage corrections
