Massachusetts Leadership on Display at Green Building Showcase
Massachusetts solidified its position as a national leader in climate-aligned building at last month’s Green Building Showcase, where an all-electric Boston Public School, affordable multi-family housing projects, and dozens of additional new construction and renovation projects showed how the local built environment is being leveraged as a climate solution.
Judges from across the country selected standout projects for their innovation, impact, and how easily they can be repeated across the spectrum of relevant building types. The annual awards program has long been an important measure of progress in building evolution, and according to Built Environment Plus Executive Director Meredith Elbaum, “the projects at this year’s showcase signal a revolution in the building sector as things we only dreamed about at the start of my career are not only being built, but these project teams are doing it with little to no cost premium.”

“These projects are real. They are happening. They are energy efficient, healthy, and cost effective. They reduce greenhouse gas emissions while saving untold millions of dollars over their lifetime. They are utilizing Mass Save incentives to generate $3 in energy cost savings for every $1 invested and they have created the new standard for building,” she added.
According to the judges, the entries marked “a notable evolution in the caliber and focus of projects in just one year. This year’s field included a multitude of examples of well-done geothermal and mass timber solutions, renovations, and building reuse.”
Schools Leading the Way
An exemplary Boston Public Schools project emerged as both the fan favorite and judges’ pick for Green Building of the Year. The Josiah Quincy Upper School (JQUS), located in Boston’s historic Chinatown, was designed by HMFH Architects to meet Boston’s Green New Deal and climate action plans, support minority students in a dense urban environment, and provide all of the educational facilities of a modern high school. The all-electric facility is one of only eight schools nation-wide to receive the U.S. Green Building Council’s LEED v4.1 Platinum certification, and demonstrates how sustainable performance and educational excellence can be achieved in dense, urban conditions, on small sites, and economically.
HMFH’s submission stated that “the school is designed for long-term financial resilience. High-efficiency easy to maintain systems and durable, low maintenance materials reduce operational costs. Participation in the Massachusetts School Building Authority’s high-performance incentives further supported cost effective green investments. This project proves that public schools can lead the way in climate action, health equity, and community empowerment, without added cost.”
The judges felt “this project does the most with the least. It supports the whole learner, addresses a broad set of sustainability issues, and fully leverages a challenging site and limited budget for maximum impact in an underserved community.”

Decarbonizing Existing Buildings
In addition to new construction, this year’s program put increasing emphasis on the work being done to transform the out-of-date existing building stock of Massachusetts into healthier and more efficient buildings. As part of its work to develop the MA Building Performance Exchange in collaboration with the Massachusetts Clean Energy Center, BE+ added a new Building Decarb Intervention Award to highlight impactful and replicable projects that are leading the way towards the state’s climate goals.
The Building Decarb Intervention Award winner was an innovative waste-heat recovery plan submitted by GreenerU for a 27-story affordable housing apartment tower in Mission Hill’s Levinson Tower. This cost-effective intervention for one of Boston’s largest affordable housing communities demonstrates the incredible win-win approaches to decarbonizing buildings for health, resilience, and long-term affordability, with energy cost savings of over $130,000 every year. According to the judges, “The renovation at Levinson is designed to improve the health of low-income residents, reduce heating costs, and capture wasted heat while providing significant decarbonization and compatibility with a future ground source heat pump. The jury was also impressed at the number of stakeholders engaged in the process. We need this kind of creativity and work at scale!”
Mass Save Incentives Driving Efficiency and Affordability
The Sustainable Building Operations award winner was another great win-win example. Aspen Air Duct Cleaning led a central ventilation system upgrade for Jaycee Place Apartments in Lowell, MA, a 138-unit affordable housing community. A combination of Aeroseal duct sealing and replacing 38 rooftop fans with appropriate tuning and commissioning for long-term efficiency reduced operating costs by over $66,000 per year. With Mass Save incentives this intervention will pay for itself in less than four years. As the judges put it, “This highly replicable project is a superb example of how high impact, low-hanging fruit projects can yield real, tangible ROIs for environmental performance, human health, and operational cost savings while maintaining continuity in building operations.”

Another great example which also leveraged Mass Save incentives for long-term affordability was The Guild in Somerville, submitted by Utile, which won the Carbon & Energy Award. The judges beamed that “The Guild masterfully reduces operational carbon through its highly efficient, all-electric design that minimizes energy use while prioritizing occupant comfort by leveraging PHIUS design principles. This is balanced by an aggressive focus on embodied carbon reduction by embracing mass timber construction and thoughtful use of materials. The project’s execution, replicable mid-rise model, and pragmatic design make it a standout example of context-sensitive, sustainable development.”
Buildings Fostering Inclusion and Belonging
Another all-electric project was an adaptive reuse of a vacant middle school in Hyde Park, turning it into inclusive affordable housing for LGBTQ+ seniors. The Pryde, submitted by DiMella Shaffer, won the Equity & Inclusion Award and blends historic preservation with energy performance. Its operation which will result in annual utility cost savings of over $100,000 per year, while retaining over 80% of the existing structure contributed to a more than 40% reduction in embodied carbon. According to the judges, “Its design goes beyond accessibility to foster belonging, dignity, and resilience, essentially turning history into hope plus national precedent and architecture into advocacy.”
DiMella Shaffer’s submission noted that “the project’s success lies in providing abundance while living within its means, demonstrating thoughtful design for economy. The team brought the Construction Manager on from the outset, fostering a collaborative approach to cost management. This ensured that design decisions balanced initial costs with long-term value, while also meeting state requirements for low-cost, high-quality construction and aligning with the owner’s standards.”

The Sustainable Whole-Building Renovation Award went to Elkus Manfredi Architects’ 40 Thorndike project transforming the 22-story brutalist courthouse tower in East Cambridge into a mixed-use, community-oriented, high-performance building. The judges celebrated the project as “a massive transformation from a brutalist courthouse to affordable apartments and office space. The team’s out-of-the-box thinking created an unexpected community asset that values occupant wellbeing as well as positive climate impact. While the specific situation may not be common, the creativity of the reinvention and the holistic benefits achieved would benefit any renovation.”
Pushing the Industry Forward
Judges also selected Marty Josten, Principal Director of Building Decarbonization at New Ecology, as Change Agent of the Year. The award recognizes her significant positive impact on the environment, social equity, and the economy by creating a blueprint for how communities can build a resilient sustainable future through collaboration. “Marty combines rigorous technical insight with deep belief in people. She’s deeply committed to helping environmental justice communities thrive by building one family at a time,” said Joyce Losick-Yang, who nominated her for the award. “Marty’s professional accomplishments are grounded in a simple and profoundly powerful kindness and compassion for others (along with a wicked sense of humor) that engenders lifelong friendships and encourages the professional development of her peers.

Promising Payback
“The treasure trove of submissions this year can really point the way forward not just for Massachusetts, but for the whole country,” said Elbaum. “One project that offers a lot of hope for cost-effectively tackling building emissions at scale is a retro-commissioning strategy by BXP and JB&B that saw payback periods of under two years. These low-hanging fruit interventions resulted in over $600,000/year in energy savings across 8 buildings. Since BXP has been a sustainability leader in the industry, their buildings are already relatively efficient. Extending this portfolio-scale intervention to the less efficient building stock across the state would yield even higher savings and is foundational to any retrofit and decarbonization planning. It would do wonders to address the affordability crisis while putting us on the right track for climate sanity.”
“What I love most about the diversity and caliber of projects at this year’s showcase, however, is that while the financial benefits of building sustainably make it an absolute no-brainer, there are qualitative and quality-of-life benefits that are just as compelling,” added Elbaum. “I wish we could do more to highlight these impactful projects. I feel like screaming this message from the rooftop.”
If the Showcase proves anything, it is that lasting affordability grows from buildings that waste less energy, and the solutions already exist. The projects honored by fifteen independent judges from outside New England demonstrate replicable strategies that deliver deep and enduring utility savings for residents and communities.
