CET’s Green Building department has played a significant part in the evolution of green building for the last 25 years. As experts in energy efficiency and building performance, the department has promoted green building, educated the residential building community, and verified the performance of homes all over the region seeking energy code compliance ore certification by ENERGY STAR, LEED for Homes, or Passive House.
After performing thousands of diagnostic tests to establish levels of energy efficiency in homes, more recently CET’s Home Energy Raters have applied their diagnostic skills to commercial building renovations and new buildings targeting green designations or compliance to the building energy code.Read More»

Q. I’ve been hearing about HERS ratings lately. What is a HERS rating?
A. HERS ratings are required for new construction projects and major renovations in any of the over 175 Massachusetts cities and towns that have adopted the stretch energy code. The HERS Index is a number that tells homeowners and home-buyers how energy efficient a home is, and how much they should expect to spend on heating and cooling costs.
The HERS rating that you receive is on an index ranging from 0 to 150, with the standard new home falling at 100, and a lower score indicating a more energy efficient home. So for example, if your home has a rating of 70, your home is 30% more efficient than the average home built today. To give some perspective, a home built in the 1950s would most likely receive a rating of 120 or 130.
The HERS Index is not only used as a tool for new home-buyers and homeowners who are renovating, but is also used as a tool in meeting energy reduction plans of many cities and towns in Massachusetts. Homes that are built today that are in one of the over 175 cities and towns in Massachusetts that follow the stretch energy code must have a HERS rating. Currently in these stretch energy code towns, homes smaller than 3000 square feet must have a 70 HERS index or lower, and homes larger than 3000 square feet must have a HERS index of 65 or lower. Starting with new homes permitted in January 2017 in stretch energy code towns, the requirement will be a HERS index of 55 or lower. There are some exceptions to the HERS 55 index for homes with renewable energy systems, Passive Houses, and ENERGY STAR certified homes.Read More»

My name is Aliza and I am the Marketing and Green Homes EcoFellow. Last week, I had the opportunity to shadow one of our Home Energy Raters, John Saveson, for a day of testing at the Leyden Woods affordable housing project. The Center for Ecotechnology’s raters are working with Delphi Construction throughout the project to ensure that the new buildings are not only going to meet Massachusetts energy code, but also will meet their goal of becoming ENERGY STAR Certified multi-family homes.
Throughout my day on the construction site I learned about the extensive process of a Home Energy Rating. In the planning stages of a high performance building project, the CET rater will meet with the developer to look at building plans and do an initial assessment of the efficiency of the home. Once the building process is underway, the rater will check that every part of the home’s insulation is up to standard in order to ensure that the finished home will be as air tight and efficient as planned.Read More»

Last week, 150 people gathered for the Soldier On groundbreaking ceremony of the second Gordon H. Mansfield Veterans Community, in Leeds, MA. This 44-unit facility, a registered LEED for Homes project seeking the “Gold” designation, serves as permanent housing for male veterans. The $8 million project was funded primarily by the US department of Veterans Affairs and state money, and follows the December 2015 opening of the four-unit women’s housing complex, also on the Leeds campus. These Soldier On projects offer homeless veterans, who have been successful participants in Soldier On programs, the opportunity to purchase an equity stake in their homes. Residents are also provided lifetime services and support including education and employment, mental health counseling and addiction treatment.Read More»

In October, the American Council for an Energy Efficient Economy (ACEEE) named Massachusetts the most energy efficient state for the fifth year in a row! Since 1976, the Center for EcoTechnology has contributed to this progress and remained on the cutting edge of green building technology. To celebrate our 40th year, we look at the green construction services, education and support CET has provided to help save residents and builders money and energy.Read More»
