Statewide Base Energy Code: Are you in Compliance?
Mandatory changes to the base energy code will be coming into effect on January 1, 2017. Local building inspectors in every town now expect builders to provide leakage testing results from both the building envelope and heating and cooling ducts. The new base energy code requirements also include mechanical ventilation, insulation upgrades, equipment sizing, and increased lighting efficacy, which to some builders may seem moderate but could be challenging to others.
CET can help you with these requirements:
- CET’s Energy Code Testing Package: site visits and diagnostic testing that will: a) help you identify your building’s air barrier and the level of envelope and duct leakage in a current or typical project, and b) work with you to develop better air sealing strategies to meet the new envelope and duct leakage requirements.

Energy Code Testing Package for New and Existing Clients
For new clients: CET offers an Energy Code Testing Package that will help you understand your air barrier design, identify your biggest air sealing opportunities, and develop air sealing strategies that will achieve the new building tightness standard of 3 air changes per hour (ACH50). The Package includes two field visits either at a current home under construction so you find out new approaches for adapting current construction techniques, or on a new home permitted after January 1st that must meet the new standard.
- Rough in inspection: mid construction air sealing inspection, blower door & duct leakage testing (one field visit)
- Final inspection: Final blower door, air flow ventilation system testing (one field visit)
You may also want to ask us about CET’s Home Energy Rating Package that would allow you to participate in Mass Save’s New Construction Incentive Program.
For existing clients: Use our Energy Code Testing Package for new homes permitted after January 1 or, if you are not sure if you are on track to meet the new standard of 3 ACH50, CET can provide testing results from previous projects. Contact Miira Gates at (413) 586-7350 x242. If previous tests indicate that you need to reduce envelope or duct leakage by 20%, 30%, 40% or more, for an hourly fee your rater will be able to help you improve your air barrier design and develop good strategies to meet the new standard on future projects.
To learn more, or to order the package for only $650, contact us at 413-586-7350 x242 or e-mail email@example.com
Stretch Energy Code
As of October 2016, the Stretch Energy Code has been adopted by over 186 Massachusetts towns. The standard requires both new and remodeled buildings to use approximately 20 percent less energy than a comparable building designed and built to the MA base energy code.
If building a new home in a Stretch Energy Code town, you must a certified Home Energy (HERS) Rater to evaluate the energy efficiency of the home, provide diagnostic testing of the duct systems and the home’s air leakage, and check compliance with the ENERGY STAR Qualified Homes Thermal Bypass Inspection Checklist.
Contact CET about a HERS Rating Package for your new home. In case your current plans won’t pass the Stretch Code requirements, we recommend getting in touch with us before construction begins and before you finalize all your plans and specifications.
Ask your HERS Rater how a HERS Rating can also be used to earn incentives for participating in the Mass Save New Construction Program.
