2024 YEAR IN REVIEW
The Built Environment Plus Community & You in 2024
Our Mission & Vision
We drive sustainable and regenerative design, construction, and operation of the built environment!
We envision a thriving and diverse community, creating a built environment of net positive systems of water and energy, of financial and social equity, and of ecological and human health.
Executive Summary
Massachusetts is leading the charge for a healthy, sustainable, and regenerative built environment. Policy changes at the state level like the specialized opt-in stretch energy code and major investments in decarbonization and climatetech are literally paving the way for positive transformation in the Commonwealth. We are back on top of USGBC’s Top 10 states for LEED certifications per capita.
In the seven years that I have been with BE+ as Executive Director, I have seen so much progress, commitment, and innovation from the local green building community. What’s most exciting to me is the way we have developed as an organization and as an ecosystem of practitioners who are lifting each other up to take on incredible challenges together.
At the heart of it all, BE+ is a community, and I have the unique privilege of seeing the fullest picture of its rigor and reach. By linking and leveraging our efforts, networks, and expertise, we tap into the power of the collective and align ourselves to maximize our impact. And what an impact we’ve made!
In so many ways, 2024 was a banner year for Built Environment Plus. We started off the year continuing our implementation of the groundbreaking Embodied Carbon Reduction Challenge with the Massachusetts Clean Energy Center (MassCEC), and ended the year by signing a contract with MassCEC to increase our efforts decarbonizing existing buildings in Massachusetts.
We sold out the 45+ speaker slots at our annual Building Tech Forum for the first time, and had record attendance at our Green Building Showcase Awards Program & Celebration. Hosted again by WS Development, the lobby of One Boston Wharf Road featured the first commercial pour of Sublime Systems’ low-carbon Sublime Cement®. We capped off our premier events with a standout Women in Green networking breakfast, featuring the co-author of Women in Green, Kira Gould. Our six topic communities continue to be the heartbeat of the organization.
In 2024, we reached record numbers of individual and company members, people hours of public interaction, events and training registrations, unique attendees, and participating companies. The number of registrations grew 37% in just one year, while total people hours of interaction jumped up 48%. We grew to seven full time employees, with more on the way, and our budget surpassed $1 million for the first time.
The BE+ Education program led the way for upskilling the professionals who are putting the BE+ mission into practice, with 117 trainings provided and over $300,000 of workforce training funds leveraged. We partnered with USGBC, NREL, and the Sponsors of Mass Save® to deliver the Solar Decathlon Professionals Training to 23 participants. We also collaborated with AIA Massachusetts and Mass Save Sponsors to launch a five-part training series on the MA Stretch Energy Code, filling over 500 seats in total!
Our April 2024 net zero report update found 48.4 million square feet of net zero and net zero ready buildings, and we renamed the report from Massachusetts is Ready for Net Zero to Massachusetts is Going Net Zero. Many of these projects and the companies and professionals building them can now be found in BE+ CONNECTS, our new high performance building professionals directory. The platform now boasts over 150 professional profiles, 120 company profiles, and over 300 project profiles, and we are expanding its use as a valuable discovery tool.
As we continue to grow the BE+ team, we’ll be able to offer even more resources, support, and opportunities for you to engage, learn, and thrive in 2025. We are energized by the possibilities and want to take a moment to express our gratitude to you. With your partnership, we are ready to make 2025 our most impactful one yet!

FILLING THE GAPSBE+ Wrapped up the Embodied Carbon Reduction Challenge with MassCEC

In March 2023, the Massachusetts Clean Energy Center and Built Environment Plus launched the first-in-the-nation Embodied Carbon Reduction Challenge in order to jump-start the upfront reduction of carbon in building projects across Massachusetts.
In April 2024, 16 teams submitted projects performing Whole Building Life Cycle Assessments (WBLCAs), and the Challenge equipped a whole new slate of design firms and practitioners with the tools and knowledge they need to take embodied carbon reductions to the next level. A panel of nine judges from across the country made their selections based on embodied carbon reduction, innovation, replicability, and cost effectiveness.
A total of $380,000 in cash prizes were awarded to 11 lead applicants during a June 20th reception at the Northeast Embodied Carbon Summit. Over 1,100 people voted in the People’s Choice selection. Together, the 16 projects made a combined embodied carbon reduction of 25k metric tons of CO2e, which is equivalent to the carbon sequestered in 413,377 tree seedlings grown for 10 years.
At Greenbuild 2024, BE+ presented the results nationally during the session The Challenge: Embodied Carbon Reduction in Buildings. In December we hosted a Lessons Learned webinar, and publicly released the results in a collection of helpful case studies.
These case studies present all 16 submitting projects in a consistent format. You can explore key results, compare the implemented low carbon strategies, and see which approaches had the greatest impact.

Massachusetts is GOING Net Zero - Spring 2024 Update released
In April of 2024, we released our 5th update to the Massachusetts is Ready for Net Zero Report.
Continued data collection since 2021 increased the total of Net Zero or Net Zero Ready Projects included in the analysis from 7.2 million GSF to 48.4 million GSF. That’s nearly a 6 times increase in known square footage in just 3 years.
It is clear from this analysis that Massachusetts is not just Ready for Net Zero, as the first three reports were named, Massachusetts is now Going Net Zero.
Of the 13.1 million GSF with reported cost data, 80% reported <1% construction cost premium to achieve Net Zero Ready. Multi-family and affordable housing’s combined 15.3 Million GSF are leading the way for Net Zero development in Massachusetts, employing heat pumps and on-site renewables to reach their Net Zero targets. Over twice as many projects since 2023 have reported the use of electricity for domestic hot water with a total of 28.2 million GSF.
There are 319 companies working to make Net Zero buildings the standard in MA. Many of the companies can be found in BE+ CONNECTS.

BE+ CONNECTS - 1st Full Year of Operation
BE+ CONNECTS is an interactive and engaging discovery tool that curates evolving companies, and their linked professionals, to promote expertise to clients designing and constructing high-performance buildings. In 2024 it hit its one year mark since going public and has so far seen a steady increase in the number of profiles on the site. To date our emphasis has been on recruiting professionals to complete profiles and add projects.
We achieved a key goal in the work this year by utilizing the site as the primary data collector for our Massachusetts is Going Net Zero Report. An expansion of the site was kicked-off at the end of the year, which will see the addition of existing buildings, and more direct user access to projects and summary report data through a dashboard. Branding will also be improved, with better marketing materials and support pages to give new users a better experience. This aligns with current plans to start expanded marketing and outreach efforts to potential users.
Looking Ahead
In 2024, we were thrilled to announce MassCEC awarding BE+ funding to deepen our programming to decarbonize existing buildings, opening up even more opportunities for learning, connection, and growth. We look forward to sharing more in 2025.
