Stricter HERS Ratings Requirements for 2024

New Homes In Massachusetts Need to Be More Energy Efficient

The HERS Rating System is a home energy performance measurement. The rating score provides builders and homeowners an idea of how well a home ranks in terms of energy use and comfort. The lower the score the better.

For new residential projects, the HERS Rating score has been progressively declining.

Starting January 1, 2023, and effective through June 30, 2024, the maximum HERS Index for new home will go down from the current 55 to a 52. Then, beginning July 1, 2024, the maximum HERS Index score  will drop to a HERS 42.

This significant drop means builders and subcontractors with new projects could be at risk. Adjustments to the project to meet the new HERS 42 requirement could include the need to replace equipment or cause delayed closings.

There are several factors that will help to make a home more energy efficient. In our expert opinion, spray foam insulation can play a big part.

Here are some benefits of spray foam insulation:

  • Effective at sealing small holes, seams and cracks, creating a vapor barrier
  • Versatile material can be installed in any home, in any space
  • Easier to apply in hard to seal places than fiberglass

The bottom line is spray foam insulation will help achieve a lower HERS score. Contact us to speak with one of our experts.

 

10-Community Fossil Fuel Ban Becomes Law

On August 10, 2022, Governor Charlie Baker signed a clean energy and climate bill to help the state reach the goal of net-zero emissions by 2050. The bill included a pilot program to allow ten cities and towns to restrict or prohibit the use of fossil fuels in most construction or major renovation projects. The proposal was signed amid opposition by labor unions, utility companies, real estate and housing organizations that the program could slow housing production.

The climate bill doesn’t dictate which 10 communities will participate in the study. The Department of Energy Resources will oversee the program and decide which communities participate based on the following criteria:

Received local approval, and has:

  • Achieved the 10% threshold on the subsidized housing inventory under Chapter 40B or have a Housing Production Plan approved by the Department of Housing and Community Development; or
  • Has approved a zoning ordinance or by-law that provides for at least 1 district of reasonable size in which multi-family housing is permitted

Ten cities and towns have already secured local approval and have submitted home rule petitions: Cambridge, Newton, Brookline, Lexington, Arlington, Concord, Lincoln, Acton, Aquinnah, and West Tisbury. Other towns and cities can still apply and have 18 months from the effective date of the new law (July 31, 2022) to achieve compliance with these requirements in order to participate in the project.

We at Greenstamp are very aware of this law change. The new law means that new construction and renovation project in the selected towns will need to go all electric. That being said, going all electric heating and cooling will require that these homes and buildings must use the best insulation possible. Building better and tighter homes will reduce the home’s energy use and carbon footprint.

We currently work with our contractors educating them on best practices to achieve this now. As this becomes more common practice over the next few years we are already ahead of the game.

 

Residential Renovation in RI gets SprayFoam

Traditionally, spring is the busiest time for builders and contractors. It’s a busy time for Greenstamp too. Our crew has been in Middleton, RI applying spray foam insulation into a home renovation project. This winter, the home will be energy efficient and the owners will see a significant reduction in heating costs.

Insulation for a Good Cause

The team at Green Stamp, in partnership with the Home Builders & Remodelers Association of Cape Cod, donated insulation and expertise for a home in Brewster MA. This home was built in one week for a family in need by members and partners of the Habitat of Humanity of Cape Cod.

We are proud to be part of this the mission to “build strength, stability and self-reliance through homeownership.”

Thank you to Robert Scott Button, owner of RSBvideo.com for the Oscar worthy time-lapse video of our 3rd Home Builders Blitz! The drone footage, hyper-lapse, and great music is amazing. The 15-minute "movie" beautifully represents the professionalism of our members. Thank you Scott! Habitat for Humanity of Cape Cod

New Construction – Newton, MA

Construction Example 1  Construction Example 2

Greenstamp insulated a custom copper roof for a new home being built in Newton, MA. The Greenstamp experts worked closely with the architects and builders through every phase of the construction project on the roof and the complete insulation system for this new home.

Our Manufacturers

Greenstamp works with several types of foam on the market. We are certified to spray foam insulation from manufacturers like, Coribond(c), Demilec(c), and Gaco Western Foam Systems. We will evaluate and recommend the best product for your project’s specific need or requirement.

Benefits of Spray Foam Insulation

 

Spray Foam Insulation

Spray Foam Insulation is a versatile material and proven solution to a variety of construction challenges like:

  • Creating of a complete air barrier
  • Controlling moisture and condensation
  • Stopping rodent and insect intrusion
  • Preventing mold
  • Inhibiting ice formation
  • Eliminating squeaky building components
  • Reducing convective currents in walls or attics
  • Reducing outside noise
  • Adding structural strength

All these benefits translate into:

  • Energy efficiency (a high R-value per inch)
  • Cost-savings, it reduces the cost of installing multiple products to achieve one thing
  • Peace of mind, it keeps unwanted things out

OPEN CELL AND CLOSED CELL

The selection of Open Cell SPF versus Closed Cell SPF depends on the project and what is needed in terms of its performance or specific application requirements.

Open Cell SPF produces cells which do not completely close when applied. Air is allowed to fill the space inside the material. It is often installed in the same way unfaced-fiberglass insulation is used. In terms of cost and R-value, Open Cell SPF is the more efficient use of polyurethane foam. In other words, as an air barrier, it uses minimal material to create maximum affect.

Closed Cell SPF produces tiny cells that are completely closed making it a denser, heavier, and stronger material. Its composition is better for preventing vapor and moisture penetration. It is often used in basements, crawlspaces, unvented cathedral ceilings, wine cellars, and other areas of high moisture potential. Despite the higher R-value, Closed Cell SPF requires more material, is more expensive and has a higher cost per R-value.

Based on our evaluation of your project, Greenstamp will help you determine the best and most cost-effective solution.
