    New solar projects will grow renewable energy generation for four major campus buildings

    by

    In the latest step to implement commitments made in MIT’s Fast Forward climate action plan, staff from the Department of Facilities; Office of Sustainability; and Environment, Health and Safety Office are advancing new solar panel installations this fall and winter on four major campus buildings: The Stratton Student Center (W20), the Dewey Library building (E53), and two newer buildings, New Vassar (W46) and the Theater Arts building (W97).These four new installations, in addition to existing rooftop solar installations on campus, are “just one part of our broader strategy to reduce MIT’s carbon footprint and transition to clean energy,” says Joe Higgins, vice president for campus services and stewardship.The installations will not only meet but exceed the target set for total solar energy production on campus in the Fast Forward climate action plan that was issued in 2021. With an initial target of 500 kilowatts of installed solar capacity on campus, the new installations, along with those already in place, will bring the total output to roughly 650 kW, exceeding the goal. The solar installations are an important facet of MIT’s approach to eliminating all direct campus emissions by 2050.The process of advancing to the stage of placing solar panels on campus rooftops is much more complex than just getting them installed on an ordinary house. The process began with a detailed assessment of the potential for reducing the campus greenhouse gas footprint. A first cut eliminated rooftops that were too shaded by trees or other buildings. Then, the schedule for regular replacement of roofs had to be taken into account — it’s better to put new solar panels on top of a roof that will not need replacement in a few years. Other roofs, especially lab buildings, simply had too much existing equipment on them to allow a large area of space for solar panels.Randa Ghattas, senior sustainability project manager, and Taya Dixon, assistant director for capital budgets and contracts within the Department of Facilities, spearheaded the project. Their initial assessment showed that there were many buildings identified with significant solar potential, and it took the impetus of the Fast Forward plan to kick things into action. Even after winnowing down the list of campus buildings based on shading and the life cycle of roof replacements, there were still many other factors to consider. Some buildings that had ample roof space were of older construction that couldn’t bear the loads of a full solar installation without significant reconstruction. “That actually has proved trickier than we thought,” Ghattas says. For example, one building that seemed a good candidate, and already had some solar panels on it, proved unable to sustain the greater weight and wind loads of a full solar installation. Structural capacity, she says, turned out to be “probably the most important” factor in this case.The roofs on the Student Center and on the Dewey Library building were replaced in the last few years with the intention of the later addition of solar panels. And the two newer buildings were designed from the beginning with solar in mind, even though the solar panels were not part of the initial construction. “The designs were built into them to accommodate solar,” Dixon says, “so those were easy options for us because we knew the buildings were solar-ready and could support solar being integrated into their systems, both the electrical system and the structural system of the roof.”But there were also other considerations. The Student Center is considered a historically significant building, so the installation had to be designed so that it was invisible from street level, even including a safety railing that had to be built around the solar array. But that was not a problem. “It was fine for this building,” Ghattas says, because it turned out that the geometry of the building and the roofs hid the safety railing from view below.Each installation will connect directly to the building’s electrical system, and thus into the campus grid. The power they produce will be used in the buildings they are on, though none will be sufficient to fully power its building. Overall, the new installations, in addition to the existing ones on the MIT Sloan School of Management building (E62) and the Alumni Pool (57) and the planned array on the new Graduate Junction dorm (W87-W88), will be enough to power 5 to 10 percent of the buildings’ electric needs, and offset about 190 metric tons of carbon dioxide emissions each year, Ghattas says. This is equivalent to the electricity use of 35 homes annually.Each building installation is expected to take just a couple of weeks. “We’re hopeful that we’re going to have everything installed and operational by the end of this calendar year,” she says.Other buildings could be added in coming years, as their roof replacement cycles come around. With the lessons learned along the way in getting to this point, Ghattas says, “now that we have a system in place, hopefully it’s going to be much easier in the future.”Higgins adds that “in parallel with the solar projects, we’re working on expanding electric vehicle charging stations and the electric vehicle fleet and reducing energy consumption in campus buildings.”Besides the on-campus improvements, he says, “MIT is focused on both the local and the global.” In addition to solar installations on campus buildings, which can only mitigate a small portion of campus emissions, “large-scale aggregation partnerships are key to moving the actual market landscape for adding cleaner energy generation to power grids,” which must ultimately lead to zero emissions, he says. “We are spurring the development of new utility-grade renewable energy facilities in regions with high carbon-intensive electrical grids. These projects have an immediate and significant impact in the urgently needed decarbonization of regional power grids.”MIT is also making more advances to accelerate renewable energy generation and electricity grid decarbonization at the local and state level. The Institute has recently concluded an agreement through the Solar Massachusetts Renewable Target program that supports the Commonwealth of Massachusetts’ state solar power development goals by enabling the construction of a new 5-megawatt solar energy facility on Cape Cod. The new solar energy system is integral to supporting a new net-zero emissions development that includes affordable housing, while also providing additional resiliency to the local grid.Higgins says that other technologies, strategies, and practices are being evaluated for heating, cooling, and power for the campus, “with zero carbon emissions by 2050, utilizing cleaner energy sources.” He adds that these campus initiatives “are part of MIT’s larger Climate Project, aiming to drive progress both on campus and beyond, advancing broader partnerships, new market models, and informing approaches to climate policy.”  More

      A bright and airy hub for climate at MIT

      by

      Seen from a distance, MIT’s Cecil and Ida Green Building (Building 54) — designed by renowned architect and MIT alumnus I.M. Pei ’40 — is one of the most iconic buildings on the Cambridge, Massachusetts, skyline. Home to the MIT Department of Earth, Atmospheric and Planetary Sciences (EAPS), the 21-story concrete structure soars over campus, topped with its distinctive spherical radar dome. Close up, however, it was a different story.A sunless, two-story, open-air plaza beneath the tower previously served as a nondescript gateway to the department’s offices, labs, and classrooms above. “It was cold and windy — probably the windiest place on campus,” EAPS department head Robert van der Hilst, the Schlumberger Professor of Earth and Planetary Sciences, told a packed auditorium inside the building in March. “You would pass through the elevators and disappear into the corridors, never to be seen again until the end of the day.”Van der Hilst was speaking at a dedication event to celebrate the opening of the renovated and expanded space, 60 years after the Green Building’s original dedication in 1964. In a dramatic transformation, the perpetually-shaded expanse beneath the tower has been filled with an airy, glassed-in structure that is as inviting as the previous space was forbidding.Designed to meet LEED-platinum certification, the newly-constructed Tina and Hamid Moghadam Building (Building 55) seems to float next to the Brutalist tower, its glass façade both opening up the interior and reflecting the sunlight and green space outside. The 300-seat auditorium within the original tower has been similarly transformed, bringing light and space to the newly dubbed Dixie Lee Bryant (1891) Lecture Hall, named after the first person to earn a geology degree at MIT.Catalyzing collaborationThe project is about more than updating an overlooked space. “The building we’re here to celebrate today does something else,” MIT President Sally Kornbluth said at the dedication.“In its lightness, in its transparency, it calls attention not to itself, but to the people gathered inside it. In its warmth, its openness, it makes room for culture and community. And it welcomes in those who don’t yet belong … as we take on the immense challenges of climate together,” she continued, referencing the recent launch of The Climate Project at MIT — a whole-of-MIT initiative to innovate bold solutions to climate change. In MIT’s famously decentralized structure, the Moghadam Building provides a new physical hub for students, scientists, and engineers interested in climate and the environment to congregate and share ideas.From the start, fostering this kind of multidisciplinary collaboration was part of Van der Hilst’s vision. In addition to serving as the flagship location for EAPS, Building 54 has long been the administrative home of the MIT-WHOI Joint Program in Oceanography/Applied Ocean Science and Engineering — a graduate program in partnership with Woods Hole Oceanographic Institute. With the addition of Building 55, EAPS has now been joined by the MIT Environmental Solutions Initiative (ESI) — a campus-wide program fostering education, outreach, and innovation in earth system science, urban infrastructure, and sustainability — and will welcome closer collaboration with Terrascope — a first-year learning community which invites its students to take on real-world environmental challenges.A shared vision comes to lifeThe building project dovetailed with the long-overdue refurbishment of the Green Building. After a multi-year fundraising campaign where Van der Hilst spearheaded the department’s efforts, the project received a major boost from lead donors Tina and Hamid Moghadam ’77, SM ’78, allowing the department to break ground in November 2021.In Moghadam, chair and CEO of Prologis, which owns 1.2 billion square feet of warehouses and other logistics infrastructure worldwide, EAPS found a fellow champion for climate and environmental innovation. By putting solar panels on the roofs of Prologis buildings, the company is now the second largest on-site producer of solar energy in the United States. “I don’t think there needs to be a trade-off between good sound economics and return on investment and solving climate change problems,” Moghadam said at the dedication. “The solutions that really work are the ones that actually make sense in a market economy.”Architectural firm AW-ARCH designed the Moghadam Building with a light touch, emphasizing spaciousness in contrast to the heavy concrete buildings that surround it. “The kind of delicacy and fragility of the thing is in some ways a depiction of what happens here,” said architect and co-founding partner Alex Anmahian at the dedication reception, giving a nod to the study of the delicate balance of the earth system itself. The sense is further illustrated by the responsiveness of the façade to the surrounding environment, which, depending on the time of day and quality of light, makes the glass alternately reflective and transparent.Inside, the 11,900-square foot pavilion is highly flexible and serves as a showcase for the science that happens in the labs and offices above. Central to the space is a 16-foot by 9-foot video wall featuring vivid footage of field work, lab research, data visualizations, and natural phenomena — visible even to passers-by outside. The video wall is counterposed to an unpretentious set of stair-step bleachers leading to the second floor that could play host to anything from a scientific lecture to a community pizza-and-movie night.Van der Hilst has referred to his vision for the atrium as a “campus living room,” and the furniture throughout is intentionally chosen to allow for impromptu rearrangements, providing a valuable public space on campus for students to work and socialize.The second level is similarly adaptable, featuring three classrooms with state-of-the-art teaching technologies that can be transformed from a single large space for a hackathon to intimate rooms for discussion.“The space is really meant for a yet unforeseen experience,” Anmahian says. “The reason it is so open is to allow for any possibility.”The inviting, dynamic design of the pavilion has also become an instant point of pride for the building’s inhabitants. At the dedication, School of Science dean Nergis Mavalvala quipped that anyone walking into the space “gains two inches in height.”Van der Hilst quoted a colleague with a similar observation: “Now, when I come into this space, I feel respected by it.”The perfect complementAnother significant feature of the project is the List Visual Arts Center Percent-for-Art Program installation by conceptual artist Julian Charrière, entitled “Everything Was Forever Until It Was No More.”Consisting of three interrelated works, the commission includes: “Not All Who Wander Are Lost,” three glacial erratic boulders which sit atop their own core samples in the surrounding green space; “We Are All Astronauts,” a trio of glass pillars containing vintage globes with distinctions between nations, land, and sea removed; and “Pure Waste,” a synthetic diamond embedded in the foundation, created from carbon captured from the air and the breath of researchers who work in the building.Known for themes that explore the transformation of the natural world over time and humanity’s complex relationship with our environment, Charrière was a perfect fit to complement the new Building 55 — offering a thought-provoking perspective on our current environmental challenges while underscoring the value of the research that happens within its walls.

      Collaborative effort supports an MIT resilient to the impacts of extreme heat

      by

      Warmer weather can be a welcome change for many across the MIT community. But as climate impacts intensify, warm days are often becoming hot days with increased severity and frequency. Already this summer, heat waves in June and July brought daily highs of over 90 degrees Fahrenheit. According to the Resilient Cambridge report published in 2021, from the 1970s to 2000, data from the Boston Logan International Airport weather station reported an average of 10 days of 90-plus temperatures each year. Now, simulations are predicting that, in the current time frame of 2015-44, the number of days above 90 F could be triple the 1970-2000 average. While the increasing heat is all but certain, how institutions like MIT will be affected and how they respond continues to evolve. “We know what the science is showing, but how will this heat impact the ability of MIT to fulfill its mission and support its community?” asks Brian Goldberg, assistant director of the MIT Office of Sustainability. “What will be the real feel of these temperatures on campus?” These questions and more are guiding staff, researchers, faculty, and students working collaboratively to understand these impacts to MIT and inform decisions and action plans in response.This work is part of developing MIT’s forthcoming Climate Resiliency and Adaptation Roadmap, which is called for in MIT’s climate action plan, and is co-led by Goldberg; Laura Tenny, senior campus planner; and William Colehower, senior advisor to the vice president for campus services and stewardship. This effort is also supported by researchers in the departments of Urban Studies and Planning, Architecture, and Electrical Engineering and Computer Science (EECS), in the Urban Risk Lab and the Senseable City Lab, as well as by staff in MIT Emergency Management and Housing and Residential Services. The roadmap — which builds upon years of resiliency planning and research at MIT — will include an assessment of current and future conditions on campus as well as strategies and proposed interventions to support MIT’s community and campus in the face of increasing climate impacts.A key piece of the resiliency puzzleWhen the City of Cambridge released their Climate Change Vulnerability Assessment in 2015, the report identified flooding and heat as primary resiliency risks to the city. In response, Institute staff worked together with the city to create a full picture of potential flood risks to both Cambridge and the campus, with the latter becoming the MIT Climate Resiliency Dashboard. The dashboard, published in the MIT Sustainability DataPool, has played an important role in campus planning and resiliency efforts since its debut in 2021, but heat has been a missing piece of the tool. This is largely because for heat, unlike flooding, few data exist relative to building-level impacts. The original assessment from Cambridge showed a model of temperature averages that could be expected in portions of the city, but understanding the measured heat impacts down to the building level is essential because impacts of heat can vary so greatly. “Heat also doesn’t conform to topography like flooding, making it harder to map it with localized specificity,” notes Tenny. “Microclimates, humidity levels, shade or sun aspect, and other factors contribute to heat risk.”Collection efforts have been underway for the past three years to fill in this gap in baseline data. Members of the Climate and Resiliency Adaptation Roadmap team and partners have helped build and place heat sensors to record and analyze data. The current heat sensors, which are shoebox-shaped devices on tripods, can be found at multiple outdoor locations on campus during the summer, capturing and recording temperatures multiple times each hour. “Urban environmental phenomena are hyperlocal. While National Weather Service readouts at locations like Logan Airport are extremely valuable, this gives us a more high-resolution understanding of the urban microclimate on our campus,” notes Sanjana Paul, past technical associate with Senseable City and current graduate student in the Department of Urban Studies and Planning who helps oversee data collection and analysis.After collection, temperature data are analyzed and mapped. The data will soon be published in the updated Climate Resiliency Dashboard and will help inform actions through the Climate Resiliency and Adaptation Roadmap, but in the meantime, the information has already provided some important insights. “There were some parts of campus that were much hotter than I expected,” explains Paul. “Some of the temperature readings across campus were regularly going over 100 degrees during heat waves. It’s a bit surprising to see three digits on a temperature reading in Cambridge.” Some strategies are also already being put into action, including planting more trees to support the urban campus forest and launching cooling locations around campus to open during days of extreme heat.As data gathering enters its fourth summer, partners continue to expand. Senseable City first began capturing data in 2021 using sensors placed on MIT Recycling trucks, and the Urban Risk Lab has offered community-centered temperature data collection with the help of its director and associate professor of architecture, Miho Mazereeuw. More recently, students in course 6.900 (Engineering for Impact) worked to design heat sensors to aid in the data collection and grow the fleet of sensors on campus. Co-instructed by EECS senior lecturer Joe Steinmeyer and EECS professor Joel Voldman, students in the course were tasked with developing technology to solve challenges close at hand. “One of the goals of the class is to tackle real-world problems so students emerge with confidence as an engineer,” explains Voldman. “Having them work on a challenge that is outside their comfort zone and impacts them really helps to engage and inspire them.” Centering on peopleWhile the temperature data offer one piece of the resiliency planning puzzle, knowing how these temperatures will affect community members is another. “When we look at impacts to our campus from heat, people are the focus,” explains Goldberg. “While stress on campus infrastructure is one factor we are evaluating, our primary focus is the vulnerability of people to extreme heat.” Impacts to community members can range from disrupted nights of sleep to heat-related illnesses.As the team looked at the data and spoke with individuals across campus, it became clear that some community members might be more vulnerable than others to the impact of extreme heat days, including ground, janitorial, and maintenance crews who work outside; kitchen staff who work close to hot equipment; and student athletes exerting themselves on hot days. “We know that people on our campus are already experiencing these extreme heat days differently,” explains Susy Jones, senior sustainability project manager in the Office of Sustainability who focuses on environmental and climate justice. “We need to design strategies and augment existing interventions with equity in mind, ensuring everyone on campus can fulfill their role at MIT.”To support those strategy decisions, the resiliency team is seeking additional input from the MIT community. One hoped-for outcome of the roadmap and dashboard is for community members to review them and offer their own insight and experiences of heat conditions on campus. “These plans need to work at the campus level and the individual,” says Goldberg. “The data tells an important story, but individuals help us complete the picture.”A model for othersAs the dashboard update nears completion and the broader resiliency and adaptation roadmap of strategies launches, their purpose is twofold: help MIT develop and inform plans and procedures for mitigating and addressing heat on campus, and serve as a model for other universities and communities grappling with the same challenges. “This approach is the center of how we operate at MIT,” explains Director of Sustainability Julie Newman. “We seek to identify solutions for our own campus in a manner that others can learn from and potentially adapt for their own resiliency and climate planning purposes. We’re also looking to align with efforts at the city and state level.” By publishing the roadmap broadly, universities and municipalities can apply lessons and processes to their own spaces.When the updated Climate Resiliency Dashboard and Climate Resiliency and Adaptation Roadmap go live, it will mark the beginning of the next phase of work, rather than an end. “The dashboard is designed to present these impacts in a way everyone can understand so people across campus can respond and help us understand what is needed for them to continue to fulfill their role at MIT,” says Goldberg. Uncertainty plays a big role in resiliency planning, and the dashboard will reflect that. “This work is not something you ever say is done,” says Goldberg. “As information and data evolves, so does our work.”  More

      At Sustainability Connect 2024, a look at how MIT is decarbonizing its campus

      by

      How is MIT working to meet its goal of decarbonizing the campus by 2050? How are local journalists communicating climate impacts and solutions to diverse audiences? What can each of us do to bring our unique skills and insight to tackle the challenges of climate and sustainability?

      These are all questions asked — and answered — at Sustainability Connect, the yearly forum hosted by the MIT Office of Sustainability that offers an inside look at this transformative and comprehensive work that is the foundation for MIT’s climate and sustainability leadership on campus. The event invites individuals in every role at MIT to learn more about the sustainability and climate work happening on campus and to share their ideas, highlight important work, and find new ways to plug into ongoing efforts. “This event is a reminder of the remarkable, diverse, and committed group of colleagues we are all part of at MIT,” said Director of Sustainability Julie Newman as the event kicked off alongside Interfaith Chaplain and Spiritual Advisor to the Indigenous Community Nina Lytton, who offered a moment of connection to attendees. At the event, that diverse and committed group was made up of more than 130 community members representing more than 70 departments, labs, and centers.

      This year, Sustainability Connect was timed with announcement of the new Climate Project at MIT, with Vice Provost Richard Lester joining the event to expound on MIT’s deep commitment to tackling the climate challenge over the next 10 years through a series of climate missions — many of which build upon the ongoing research taking place across campus already. In introducing the Climate Project at MIT, Lester echoed the theme of connection and collaboration. “This plan is about helping bridge the gap between what we would accomplish as a collection of energetic, talented, ambitious individuals, and what we’re capable of if we act together,” he said.

      Sustainability Connect 2024: Decarbonizing the Campus Video: MIT Office of Sustainability

      Highlighting one of the many collaborative efforts to address MIT’s contributions to climate change was the Decarbonizing the Campus panel, which provided a real-time look at MIT’s work to eliminate carbon emissions from campus by 2050. Newman and Vice President for Campus Services and Stewardship Joe Higgins, along with Senior Campus Planner Vasso Mathes, Senior Sustainability Project Manager Steve Lanou, and PhD student Chenhan Shao, shared the many ways MIT is working to decarbonize its campus now and respond to evolving technologies and policies in the future. “A third of MIT’s faculty and researchers … are working to identify ways in which MIT can amplify its contributions to addressing the world’s climate crisis. But part and parcel to that goal is we’re putting significant effort into decarbonizing MIT’S own carbon footprint here on our campus,” Higgins said before highlighting how MIT continues to work on projects focused on building efficiency, renewable energy on campus and off, and support of a cleaner grid, among many decarbonization strategies.

      Newman shared the way in which climate education and research play an important role through the Decarbonization Working Group research streams, and courses like class 4.s42 (Carbon Reduction Pathways for the MIT Campus) offered by Professor Christoph Reinhart. Lanou and Shao also showcased how MIT is optimizing its response to Cambridge’s Building Energy Use Disclosure Ordinance, which is aimed at tracking and reducing emissions from large commercial properties in the city with a goal of net-zero buildings by 2035. “We’ve been able [create] pathways that would be practical, innovative, have a high degree of accountability, and that could work well within the structures and the limitations that we have,” Lanou said before debuting a dashboard he and Shao developed during Independent Activities Period to track and forecast work to meet the Cambridge goal. 

      MIT’s robust commitment to decarbonize its campus goes beyond energy systems, as highlighted by the work of many staff members who led roundtables as part of Sustainability in Motion, where attendees were invited to sit down with colleagues from across campus responsible for implementing the numerous climate and sustainability commitments. Teams reported out on progress to date on a range of efforts including sustainable food systems, safe and sustainable labs, and procurement. “Tackling the unprecedented challenges of a changing planet in and around MIT takes the support of individuals and teams from all corners of the Institute,” said Assistant Director of Sustainability Brian Goldberg in leading the session. “Whether folks have sustainability or climate in their job title, or they’ve contributed countless volunteer hours to the cause, our community members are leading many meaningful efforts to transform MIT.”

      Sustainability Connect 2024: Climate in the Media PanelVideo: Office of Sustainability

      The day culminated with a panel on climate in the media, taking the excitement from the room and putting it in context — how do you translate this work, these solutions, and these challenges for a diverse audience with an ever-changing appetite for these kinds of stories? Laur Hesse Fisher, program director for the Environmental Solutions Initiate (ESI); Barbara Moran, climate and environment reporter at WBUR radio; and independent climate journalist Annie Ropeik joined the panel moderated by Knight Science Journalism Program at MIT Director Deborah Blum. Blum spoke of the current mistrust of not only the media but of news stories of climate impacts and even solutions. “To those of us telling the story of climate change, how do we reach resistant audiences? How do we gain their trust?” she asked.

      Fisher, who hosts the TIL Climate podcast and leads the ESI Journalism Fellowship, explained how she shifts her approach depending on her audience. “[With TIL Climate], a lot of what we do is, we try to understand what kinds of questions people have,” she said. “We have people submit questions to us, and then we answer them in language that they can understand.”

      For Moran, reaching audiences relies on finding the right topic to bridge to deeper issues. On a recent story about solar arrays and their impact on forests and the landscape around them, Moran saw bees and pollinators as the way in. “I can talk about bees and flowers. And that will hook people enough to get in. And then through that, we can address this issue of forest versus commercial solar and this tension, and what can be done to address that, and what’s working and what’s not,” she said.

      The panel highlighted that even as climate solutions and challenges become clearer, communicating them can remain a challenge. “Sustainability Connect is invaluable when it comes to sharing our work and bringing more people in, but over the years, it’s become clear how many people are still outside of these conversations,” said Newman. “Capping the day off with this conversation on climate in the media served as a jumping-off point for all of us to think how we can better communicate our efforts and tackle the challenges that keep us from bringing everyone to the table to help us find and share solutions for addressing climate change. It’s just the beginning of this conversation.” More

      Faculty, staff, students to evaluate ways to decarbonize MIT’s campus

      by

      With a goal to decarbonize the MIT campus by 2050, the Institute must look at “new ideas, transformed into practical solutions, in record time,” as stated in “Fast Forward: MIT’s Climate Action Plan for the Decade.” This charge calls on the MIT community to explore game-changing and evolving technologies with the potential to move campuses like MIT away from carbon emissions-based energy systems.

      To help meet this tremendous challenge, the Decarbonization Working Group — a new subset of the Climate Nucleus — recently launched. Comprised of appointed MIT faculty, researchers, and students, the working group is leveraging its members’ expertise to meet the charge of exploring and assessing existing and in-development solutions to decarbonize the MIT campus by 2050. The group is specifically charged with informing MIT’s efforts to decarbonize the campus’s district energy system.

      Co-chaired by Director of Sustainability Julie Newman and Department of Architecture Professor Christoph Reinhart, the working group includes members with deep knowledge of low- and zero-carbon technologies and grid-level strategies. In convening the group, Newman and Reinhart sought out members researching these technologies as well as exploring their practical use. “In my work on multiple projects on campus, I have seen how cutting-edge research often relies on energy-intensive equipment,” shares PhD student and group member Ippolyti Dellatolas. “It’s clear how new energy-efficiency strategies and technologies could use campus as a living lab and then broadly deploy these solutions across campus for scalable emissions reductions.” This approach is one of MIT’s strong suits and a recurring theme in its climate action plans — using the MIT campus as a test bed for learning and application. “We seek to study and analyze solutions for our campus, with the understanding that our findings have implications far beyond our campus boundaries,” says Newman.

      The efforts of the working group represent just one part of the multipronged approach to identify ways to decarbonize the MIT campus. The group will work in parallel and at times collaboratively with the team from the Office of the Vice President for Campus Services and Stewardship that is managing the development plan for potential zero-carbon pathways for campus buildings and the district energy system. In May 2023, MIT engaged Affiliated Engineers, Inc. (AEI), to support the Institute’s efforts to identify, evaluate, and model various carbon-reduction strategies and technologies to provide MIT with a series of potential decarbonization pathways. Each of the pathways must demonstrate how to manage the generation of energy and its distribution and use on campus. As MIT explores electrification, a significant challenge will be the availability of resilient clean power from the grid to help generate heat for our campus without reliance on natural gas.

      When the Decarbonization Working Group began work this fall, members took the time to learn more about current systems and baseline information. Beginning this month, members will organize analysis around each of their individual areas of expertise and interest and begin to evaluate existing and emerging carbon reduction technologies. “We are fortunate that there are constantly new ideas and technologies being tested in this space and that we have a committed group of faculty working together to evaluate them,” Newman says. “We are aware that not every technology is the right fit for our unique dense urban campus, and nor are we solving for a zero-carbon campus as an island, but rather in the context of an evolving regional power grid.”

      Supported by funding from the Climate Nucleus, evaluating technologies will include site visits to locations where priority technologies are currently deployed or being tested. These site visits may range from university campuses implementing district geothermal and heat pumps to test sites of deep geothermal or microgrid infrastructure manufacturers. “This is a unique moment for MIT to demonstrate leadership by combining best decarbonization practices, such as retrofitting building systems to achieve deep energy reductions and converting to low-temperature district heating systems with ‘nearly there’ technologies such as deep geothermal, micronuclear, energy storage, and ubiquitous occupancy-driven temperature control,” says Reinhart. “As first adopters, we can find out what works, allowing other campuses to follow us at reduced risks.”

      The findings and recommendations of the working group will be delivered in a report to the community at the end of 2024. There will be opportunities for the MIT community to learn more about MIT’s decarbonization efforts at community events on Jan. 24 and March 14, as well as MIT’s Sustainability Connect forum on Feb. 8.

      Celebrating five years of MIT.nano

      by

      There is vast opportunity for nanoscale innovation to transform the world in positive ways — expressed MIT.nano Director Vladimir Bulović as he posed two questions to attendees at the start of the inaugural Nano Summit: “Where are we heading? And what is the next big thing we can develop?”

      “The answer to that puts into perspective our main purpose — and that is to change the world,” Bulović, the Fariborz Maseeh Professor of Emerging Technologies, told an audience of more than 325 in-person and 150 virtual participants gathered for an exploration of nano-related research at MIT and a celebration of MIT.nano’s fifth anniversary.

      Over a decade ago, MIT embarked on a massive project for the ultra-small — building an advanced facility to support research at the nanoscale. Construction of MIT.nano in the heart of MIT’s campus, a process compared to assembling a ship in a bottle, began in 2015, and the facility launched in October 2018.

      Fast forward five years: MIT.nano now contains nearly 170 tools and instruments serving more than 1,200 trained researchers. These individuals come from over 300 principal investigator labs, representing more than 50 MIT departments, labs, and centers. The facility also serves external users from industry, other academic institutions, and over 130 startup and multinational companies.

      A cross section of these faculty and researchers joined industry partners and MIT community members to kick off the first Nano Summit, which is expected to become an annual flagship event for MIT.nano and its industry consortium. Held on Oct. 24, the inaugural conference was co-hosted by the MIT Industrial Liaison Program.

      Six topical sessions highlighted recent developments in quantum science and engineering, materials, advanced electronics, energy, biology, and immersive data technology. The Nano Summit also featured startup ventures and an art exhibition.

      Watch the videos here.

      Seeing and manipulating at the nanoscale — and beyond

      “We need to develop new ways of building the next generation of materials,” said Frances Ross, the TDK Professor in Materials Science and Engineering (DMSE). “We need to use electron microscopy to help us understand not only what the structure is after it’s built, but how it came to be. I think the next few years in this piece of the nano realm are going to be really amazing.”

      Speakers in the session “The Next Materials Revolution,” chaired by MIT.nano co-director for Characterization.nano and associate professor in DMSE James LeBeau, highlighted areas in which cutting-edge microscopy provides insights into the behavior of functional materials at the nanoscale, from anti-ferroelectrics to thin-film photovoltaics and 2D materials. They shared images and videos collected using the instruments in MIT.nano’s characterization suites, which were specifically designed and constructed to minimize mechanical-vibrational and electro-magnetic interference.

      Later, in the “Biology and Human Health” session chaired by Boris Magasanik Professor of Biology Thomas Schwartz, biologists echoed the materials scientists, stressing the importance of the ultra-quiet, low-vibration environment in Characterization.nano to obtain high-resolution images of biological structures.

      “Why is MIT.nano important for us?” asked Schwartz. “An important element of biology is to understand the structure of biology macromolecules. We want to get to an atomic resolution of these structures. CryoEM (cryo-electron microscopy) is an excellent method for this. In order to enable the resolution revolution, we had to get these instruments to MIT. For that, MIT.nano was fantastic.”

      Seychelle Vos, the Robert A. Swanson (1969) Career Development Professor of Life Sciences, shared CryoEM images from her lab’s work, followed by biology Associate Professor Joey Davis who spoke about image processing. When asked about the next stage for CryoEM, Davis said he’s most excited about in-situ tomography, noting that there are new instruments being designed that will improve the current labor-intensive process.

      To chart the future of energy, chemistry associate professor Yogi Surendranath is also using MIT.nano to see what is happening at the nanoscale in his research to use renewable electricity to change carbon dioxide into fuel.

      “MIT.nano has played an immense role, not only in facilitating our ability to make nanostructures, but also to understand nanostructures through advanced imaging capabilities,” said Surendranath. “I see a lot of the future of MIT.nano around the question of how nanostructures evolve and change under the conditions that are relevant to their function. The tools at MIT.nano can help us sort that out.”

      Tech transfer and quantum computing

      The “Advanced Electronics” session chaired by Jesús del Alamo, the Donner Professor of Science in the Department of Electrical Engineering and Computer Science (EECS), brought together industry partners and MIT faculty for a panel discussion on the future of semiconductors and microelectronics. “Excellence in innovation is not enough, we also need to be excellent in transferring these to the marketplace,” said del Alamo. On this point, panelists spoke about strengthening the industry-university connection, as well as the importance of collaborative research environments and of access to advanced facilities, such as MIT.nano, for these environments to thrive.

      The session came on the heels of a startup exhibit in which eleven START.nano companies presented their technologies in health, energy, climate, and virtual reality, among other topics. START.nano, MIT.nano’s hard-tech accelerator, provides participants use of MIT.nano’s facilities at a discounted rate and access to MIT’s startup ecosystem. The program aims to ease hard-tech startups’ transition from the lab to the marketplace, surviving common “valleys of death” as they move from idea to prototype to scaling up.

      When asked about the state of quantum computing in the “Quantum Science and Engineering” session, physics professor Aram Harrow related his response to these startup challenges. “There are quite a few valleys to cross — there are the technical valleys, and then also the commercial valleys.” He spoke about scaling superconducting qubits and qubits made of suspended trapped ions, and the need for more scalable architectures, which we have the ingredients for, he said, but putting everything together is quite challenging.

      Throughout the session, William Oliver, professor of physics and the Henry Ellis Warren (1894) Professor of Electrical Engineering and Computer Science, asked the panelists how MIT.nano can address challenges in assembly and scalability in quantum science.

      “To harness the power of students to innovate, you really need to allow them to get their hands dirty, try new things, try all their crazy ideas, before this goes into a foundry-level process,” responded Kevin O’Brien, associate professor in EECS. “That’s what my group has been working on at MIT.nano, building these superconducting quantum processors using the state-of-the art fabrication techniques in MIT.nano.”

      Connecting the digital to the physical

      In his reflections on the semiconductor industry, Douglas Carlson, senior vice president for technology at MACOM, stressed connecting the digital world to real-world application. Later, in the “Immersive Data Technology” session, MIT.nano associate director Brian Anthony explained how, at the MIT.nano Immersion Lab, researchers are doing just that.

      “We think about and facilitate work that has the human immersed between hardware, data, and experience,” said Anthony, principal research scientist in mechanical engineering. He spoke about using the capabilities of the Immersion Lab to apply immersive technologies to different areas — health, sports, performance, manufacturing, and education, among others. Speakers in this session gave specific examples in hardware, pediatric health, and opera.

      Anthony connected this third pillar of MIT.nano to the fab and characterization facilities, highlighting how the Immersion Lab supports work conducted in other parts of the building. The Immersion Lab’s strength, he said, is taking novel work being developed inside MIT.nano and bringing it up to the human scale to think about applications and uses.

      Artworks that are scientifically inspired

      The Nano Summit closed with a reception at MIT.nano where guests could explore the facility and gaze through the cleanroom windows, where users were actively conducting research. Attendees were encouraged to visit an exhibition on MIT.nano’s first- and second-floor galleries featuring work by students from the MIT Program in Art, Culture, and Technology (ACT) who were invited to utilize MIT.nano’s tool sets and environments as inspiration for art.

      In his closing remarks, Bulović reflected on the community of people who keep MIT.nano running and who are using the tools to advance their research. “Today we are celebrating the facility and all the work that has been done over the last five years to bring it to where it is today. It is there to function not just as a space, but as an essential part of MIT’s mission in research, innovation, and education. I hope that all of us here today take away a deep appreciation and admiration for those who are leading the journey into the nano age.” More

      Robert van der Hilst to step down as head of the Department of Earth, Atmospheric and Planetary Sciences

      by

      Robert van der Hilst, the Schlumberger Professor of Earth and Planetary Sciences, has announced his decision to step down as the head of the Department of Earth, Atmospheric and Planetary Sciences at the end of this academic year.  A search committee will convene later this spring to recommend candidates for Van der Hilst’s successor.

      “Rob is a consummate seismologist whose images of Earth’s interior structure have deepened our understanding of how tectonic plates move, how mantle convection works, and why some areas of the Earth are hot-spots for seismic and geothermal activity,” says Nergis Mavalvala, the Curtis and Kathleen Marble Professor of Astrophysics and the dean of the MIT School of Science. “As an academic leader, Rob has been a steadfast champion of the department’s cross-cutting research and education missions, especially regarding climate sciences writ large at MIT. His commitment to diversity and community have made the department — and indeed, MIT — a better place to do our best work.”

      “For 12 years, it has been my honor to lead this department and collaborate with all our community members — faculty, staff, and students,” says Van der Hilst. “EAPS is at the vanguard of climate science research at MIT, as well Earth and planetary sciences and studies into the co-evolution of life and changing environments.”

      Among his other leadership roles on campus, Van der Hilst most recently served as co-chair of the faculty review committee for MIT’s Climate Grand Challenges in which EAPS researchers secured nine finalists and two, funded flagship projects. He also serves on the Institute’s Climate Nucleus to help enact Fast Forward: MIT’s Climate Action Plan for the Decade.

      In his more-than-decade as department head, one of Van der Hilst’s major initiatives has been developing, funding, and constructing the Tina and Hamid Moghadam Building, rapidly nearing completion adjacent to Building 54. The $35 million, LEED-platinum Building 55 will be a vital center and showcase for environmental and climate research on MIT’s campus. With assistance from the Institute and generous donors, the renovations and expansion will add classrooms, meeting, and event spaces, and bring headquarters offices for EAPS, the MIT/Woods Hole Oceanographic Institution (WHOI) Joint Program in Oceanography/Applied Ocean Science, and MIT’s Environmental Solutions Initiative (ESI) together, all under one roof.

      He also helped secure the generous gift that funded the Norman C. Rasmussen Laboratory for climate research in Building 4, as well as the Peter H. Stone and Paola Malanotte Stone Professorship, now held by prominent atmospheric scientist Arlene Fiore.

      On the academic side of the house, Van der Hilst and his counterpart from the Department of Civil and Environmental Engineering (CEE), Ali Jadbabaie, the JR East Professor and CEE department head, helped develop MIT’s new bachelor of science in climate system science and engineering (Course 1-12), jointly offered by EAPS and CEE.

      As part of MIT’s commitment to aid the global response to climate change, the new degree program is designed to train the next generation of leaders, providing a foundational understanding of both the Earth system and engineering principles — as well as an understanding of human and institutional behavior as it relates to the climate challenge.

      Beyond climate research, Van der Hilst’s tenure at the helm of the department has seen many research breakthroughs and accomplishments: from high-profile NASA missions with EAPS science leadership, including the most recent launch of the Psyche mission and the successful asteroid sample return from OSIRIS-REx, to the development of next-generation models capable of describing Earth systems with increasing detail and accuracy. Van der Hilst helped enable such scientific advancements through major improvements to experimental facilities across the department, and, more generally, his mission to double the number of fellowships available to EAPS graduate students.

      “By reducing the silos and inequities created by our disciplinary groups, we were able to foster collaborations that allow faculty, students, and researchers to explore fundamental science questions in novel ways that expand our understanding of the natural world — with profound implications for helping to guide communities and policymakers toward a sustainable future,” says Van der Hilst.

      Community-focused

      In 2019, Van der Hilst began looking ahead to the department’s 40th anniversary in 2023 and charged a number of working groups to evaluate the department’s past and present, and to re-imagine its future. Led by faculty, staff, and students, Task Force 2023 was a yearlong exercise of data-gathering and community deliberation, looking broadly at three focus areas: Image, Visibility, and Relevance; External Synergies: collaboration and partnerships across campus; and Departmental Organization and Cohesion. Despite being interrupted by the pandemic, the resulting reports became a detailed blueprint for EAPS to capitalize on its strengths and begin to effect systemic improvements in areas like undergraduate education, external messaging, and recognition and belonging for administrative and research staff.

      In addition to helping the department mark its 40th anniversary with a celebration this coming spring, Van der Hilst will oversee the dedication of the Moghadam Building, including the renaming of lecture hall 54-100 for Dixie Lee Bryant, the first recipient (woman or man) of a geology degree from MIT in 1891.

      As department head, faculty renewal and retention were key areas of focus for Van der Hilst. In addition to improvements in the faculty search process, he was responsible for the appointment of 20 new faculty members, and in the process shifted the gender ratio from one-fifth to one-third of the faculty identifying as female; he also oversaw the development and implementation of a successful junior faculty mentoring program within EAPS in 2013.

      Van der Hilst also made great strides toward improving diversity, equity, and inclusion within the department in other ways. In 2016, he formed the inaugural EAPS Diversity Council (now the Diversity, Equity and Inclusion Committee) and, in 2020, made EAPS the first department at MIT to appoint an associate department head for diversity, equity, and inclusion, tapping Associate Professor David McGee to guide ongoing community dialogues and initiatives supporting improvements in composition, achievement, belonging, engagement, and accountability.

      With McGee and EAPS student leadership, Van der Hilst supported the EAPS response to calls for social justice leadership and participation in national initiatives such as the American Geophysical Union’s Unlearning Racism in Geoscience program, and he helped navigate the changes brought on by the Covid-19 pandemic while maintaining a sense of community.

      Seismic shift

      After stepping down from his current role, Van der Hilst will have more time to catch up on research aimed at understanding of Earth’s deep interior structure and its evolution. With research collaborators, he developed seismic imaging methods to explore Earth’s interior from sedimentary basins near its surface down to the core–mantle boundary some 2,800 kilometers under the surface. Recently, he authored a Nature Communications paper with doctoral student Shujuan Mao PhD ’21 on a pilot application that uses seismometers as a cost-effective way to monitor and map groundwater fluctuations in order to measure groundwater reserves.

      Before becoming department head, Van der Hilst served as the director of the Earth Resources Laboratory (ERL). In the eight years he served as director, he helped to integrate across disciplines, departments, and schools, transforming ERL into MIT’s primary home for research and education focused on subsurface energy resources.

      Van der Hilst was named a fellow of the American Geophysical Union (AGU) in 1997 and became a fellow of the American Academy of Arts and Sciences in 2014. Before he was named the Schlumberger Professor in 2011, Van der Hilst held a Cecil and Ida Green professorship chair. He has received many awards, including the Doornbos Memorial Prize from the International Association of Seismology and Physics of the Earth’s Interior, AGU’s James B. Macelwane Medal, a Packard Fellowship, and a VICI Innovative Research Award from the Dutch National Science Foundation.

      Van der Hilst received his PhD in geophysics from Utrecht University in 1990. After postdoctoral research at the University of Leeds and the Australian National University, he joined the MIT faculty in 1996. He was ERL director from 2004 to 2012, when he was then named EAPS department head, succeeding Maria Zuber, the E. A. Griswold Professor of Geophysics, MIT vice president for research, and presidential advisor for science and technology policy. More

      AI pilot programs look to reduce energy use and emissions on MIT campus

      by

      Smart thermostats have changed the way many people heat and cool their homes by using machine learning to respond to occupancy patterns and preferences, resulting in a lower energy draw. This technology — which can collect and synthesize data — generally focuses on single-dwelling use, but what if this type of artificial intelligence could dynamically manage the heating and cooling of an entire campus? That’s the idea behind a cross-departmental effort working to reduce campus energy use through AI building controls that respond in real-time to internal and external factors. 

      Understanding the challenge

      Heating and cooling can be an energy challenge for campuses like MIT, where existing building management systems (BMS) can’t respond quickly to internal factors like occupancy fluctuations or external factors such as forecast weather or the carbon intensity of the grid. This results in using more energy than needed to heat and cool spaces, often to sub-optimal levels. By engaging AI, researchers have begun to establish a framework to understand and predict optimal temperature set points (the temperature at which a thermostat has been set to maintain) at the individual room level and take into consideration a host of factors, allowing the existing systems to heat and cool more efficiently, all without manual intervention. 

      “It’s not that different from what folks are doing in houses,” explains Les Norford, a professor of architecture at MIT, whose work in energy studies, controls, and ventilation connected him with the effort. “Except we have to think about things like how long a classroom may be used in a day, weather predictions, time needed to heat and cool a room, the effect of the heat from the sun coming in the window, and how the classroom next door might impact all of this.” These factors are at the crux of the research and pilots that Norford and a team are focused on. That team includes Jeremy Gregory, executive director of the MIT Climate and Sustainability Consortium; Audun Botterud, principal research scientist for the Laboratory for Information and Decision Systems; Steve Lanou, project manager in the MIT Office of Sustainability (MITOS); Fran Selvaggio, Department of Facilities Senior Building Management Systems engineer; and Daisy Green and You Lin, both postdocs.

      The group is organized around the call to action to “explore possibilities to employ artificial intelligence to reduce on-campus energy consumption” outlined in Fast Forward: MIT’s Climate Action Plan for the Decade, but efforts extend back to 2019. “As we work to decarbonize our campus, we’re exploring all avenues,” says Vice President for Campus Services and Stewardship Joe Higgins, who originally pitched the idea to students at the 2019 MIT Energy Hack. “To me, it was a great opportunity to utilize MIT expertise and see how we can apply it to our campus and share what we learn with the building industry.” Research into the concept kicked off at the event and continued with undergraduate and graduate student researchers running differential equations and managing pilots to test the bounds of the idea. Soon, Gregory, who is also a MITOS faculty fellow, joined the project and helped identify other individuals to join the team. “My role as a faculty fellow is to find opportunities to connect the research community at MIT with challenges MIT itself is facing — so this was a perfect fit for that,” Gregory says. 

      Early pilots of the project focused on testing thermostat set points in NW23, home to the Department of Facilities and Office of Campus Planning, but Norford quickly realized that classrooms provide many more variables to test, and the pilot was expanded to Building 66, a mixed-use building that is home to classrooms, offices, and lab spaces. “We shifted our attention to study classrooms in part because of their complexity, but also the sheer scale — there are hundreds of them on campus, so [they offer] more opportunities to gather data and determine parameters of what we are testing,” says Norford. 

      Developing the technology

      The work to develop smarter building controls starts with a physics-based model using differential equations to understand how objects can heat up or cool down, store heat, and how the heat may flow across a building façade. External data like weather, carbon intensity of the power grid, and classroom schedules are also inputs, with the AI responding to these conditions to deliver an optimal thermostat set point each hour — one that provides the best trade-off between the two objectives of thermal comfort of occupants and energy use. That set point then tells the existing BMS how much to heat up or cool down a space. Real-life testing follows, surveying building occupants about their comfort. Botterud, whose research focuses on the interactions between engineering, economics, and policy in electricity markets, works to ensure that the AI algorithms can then translate this learning into energy and carbon emission savings. 

      Currently the pilots are focused on six classrooms within Building 66, with the intent to move onto lab spaces before expanding to the entire building. “The goal here is energy savings, but that’s not something we can fully assess until we complete a whole building,” explains Norford. “We have to work classroom by classroom to gather the data, but are looking at a much bigger picture.” The research team used its data-driven simulations to estimate significant energy savings while maintaining thermal comfort in the six classrooms over two days, but further work is needed to implement the controls and measure savings across an entire year. 

      With significant savings estimated across individual classrooms, the energy savings derived from an entire building could be substantial, and AI can help meet that goal, explains Botterud: “This whole concept of scalability is really at the heart of what we are doing. We’re spending a lot of time in Building 66 to figure out how it works and hoping that these algorithms can be scaled up with much less effort to other rooms and buildings so solutions we are developing can make a big impact at MIT,” he says.

      Part of that big impact involves operational staff, like Selvaggio, who are essential in connecting the research to current operations and putting them into practice across campus. “Much of the BMS team’s work is done in the pilot stage for a project like this,” he says. “We were able to get these AI systems up and running with our existing BMS within a matter of weeks, allowing the pilots to get off the ground quickly.” Selvaggio says in preparation for the completion of the pilots, the BMS team has identified an additional 50 buildings on campus where the technology can easily be installed in the future to start energy savings. The BMS team also collaborates with the building automation company, Schneider Electric, that has implemented the new control algorithms in Building 66 classrooms and is ready to expand to new pilot locations. 

      Expanding impact

      The successful completion of these programs will also open the possibility for even greater energy savings — bringing MIT closer to its decarbonization goals. “Beyond just energy savings, we can eventually turn our campus buildings into a virtual energy network, where thousands of thermostats are aggregated and coordinated to function as a unified virtual entity,” explains Higgins. These types of energy networks can accelerate power sector decarbonization by decreasing the need for carbon-intensive power plants at peak times and allowing for more efficient power grid energy use.

      As pilots continue, they fulfill another call to action in Fast Forward — for campus to be a “test bed for change.” Says Gregory: “This project is a great example of using our campus as a test bed — it brings in cutting-edge research to apply to decarbonizing our own campus. It’s a great project for its specific focus, but also for serving as a model for how to utilize the campus as a living lab.” More
