Stretch Code

As of December 16, 2010, 53 Massachusetts communities have successfully met the five program criteria to earn designation as a “Green Community”. One of these criteria requires stricter measures for new buildings and additions over 500 sq. ft. It can be difficult navigating these new requirements and teaming up with knowledgeable professionals who understand the process is both cost and time efficient. Our HERS rater services will assist you in complying with the new minimum standards.

The most cost-effective way is to do it right the first time. We can help by modeling your home’s performance before construction begins and then field testing to assure design measures have been reached or exceeded. Our goal is to insure success for all parties. Client satisfaction is our top priority.

In addition, we will help you to apply for the incentives available through utility programs:

JSR Stretch Code Process for New Homes

  1. Meet with the Owner/Architect to discuss design and material selections for Building Envelope, Mechanical Systems and Appliances.
  2. Model design by entering into REM/Rate software to determine projected HERS Rating. If needed, recommend additional measures to achieve a HERS score of 65-70 depending on size of home (80 for additions to existing homes).
  3. Meet with contractor and subcontractors to discuss how work will be monitored and tested so performance expectations are understood before work begins.
  4. Inspect the air sealing & duct work leakage, if applicable, prior to insulation.
  5. Inspect insulation prior to sheetrock or plaster installation.
  6. Perform final blower door test and inspection of appliances. Complete Thermal Bypass Checklist and file paperwork with authorities.
