Newsletter v041: The Center for Building Performance and Diagnostics
Dear School of Architecture Community,
The leaves on the trees outside my office signal the arrival of fall in Pittsburgh and with it, the cadence of the second half of the semester. From our first-year undergraduates, comprising one of our largest cohorts in recent years, to upper-level B.Arch and M.Arch students in our Advanced Option Studios, to students across our graduate programs, the school is humming. We are entering one of my favorite times of the semester, when student projects gain momentum, studios begin to fill with work, and making spaces reveal the enduring value of learning hands-on, in community.
I recently had the pleasure of welcoming families of first-year students to campus as part of CMU's Family Weekend. Our event was fresh on the heels of the first years' kayaking trip along the Allegheny River and was a great opportunity to share how Pittsburgh serves as an indispensable teacher and laboratory for our programs. While the first-year students are learning about urban edge conditions, our first-semester M.Arch students are imagining alternative, transitional futures for Pittsburgh's Chateau neighborhood. Our local activities are complemented by engagements further afield. Students in Professor Juney Lee's advanced option studio, "From Steel to Timber City — Reimagining Mass Timber Structural Systems," traveled over fall break to the Southeastern U.S. to visit some of North America's largest mass timber manufacturers and fabricators. And just this week, second-year M.Arch students hosted Pecha Kucha presentations to share their international summer travel research.
This fall, I am honored to step into the role of Associate Head for Design Fundamentals. Having spent 18 years on this faculty, I am continually inspired by the interactions within our community and the profound potential of architecture, and I am eager to bring this perspective to my new responsibilities. I've convened a group of faculty across the undergraduate programs to review our core curriculum and recommend a framework to inform design education in our bachelor's programs. Concurrently, we've begun making incremental improvements to our collective spaces to enhance the student experience and foster a culture of public exhibition and exchange. I am excited to contribute to the school in this capacity and look forward to working closely with students, faculty, and staff across our programs.
In this issue, we direct attention to the Center for Building Performance and Diagnostics, an internationally renowned research center at Carnegie Mellon Architecture with a noteworthy legacy of advancing sustainability and advanced technologies within the built environment — and with alumni, like Siliang Lu (PhD-BPD '19), extending that legacy around the world. It's fitting within this year's theme of research that we feature one of the enduring anchors of architectural research with a demonstrated impact well beyond our institution.
From the hands-on masonry build of our second-year students to the Remaking Cities Institute's faculty dialogues on our urban futures, the school is deeply engaged in its mission. I encourage everyone to walk through the studios and hallways in the coming weeks to witness the incredible work taking shape. Here's to a productive and inspiring conclusion to the fall term.

Associate Professor & Associate Head for Design Fundamentals
When it comes to research at Carnegie Mellon Architecture (CM–A), there is no entity as storied as the Center for Building Performance and Diagnostics (CBPD).
Housed in the iconic Robert L. Preger Intelligent Workplace atop Margaret Morrison Carnegie Hall, the CBPD has spent nearly half a century leading global thought and action in the domains of high-performance buildings, the workplace of the future, and energy and resource effectiveness.
The Center has its roots in the 1970s, when CM–A launched two major research-centric Ph.D. programs: one in computational design and another in advanced building studies (now building performance and diagnostics). These two were later followed by a third Ph.D. program in architecture, engineering, and construction management. All three programs actively engage graduate students at the master's and Ph.D. levels in research with clients in government and industry.
According to University Professor and CBPD Co-Director Vivian Loftness, from its inception the CBPD has been "committed to doing research directly with the decision-making community, advancing innovative systems, design standards and public policy with government, manufacturers and practitioners."
In the 1980s, the CBPD launched the Advanced Building Systems Integration Consortium (ABSIC), the first National Science Foundation (NSF) university-industry-government consortium partnership and the brainchild of Professor Emeritus Volker Hartkopf. Loftness explains, "at the time, even leading companies and government agencies had tiny in-house research teams and no tradition of funding academic institutions. From the CBPD, ABSIC convened the leaders of companies creating high-performance products and systems several times each year to identify common research goals and pool financial resources to fund that research. Since 1985, the CBPD has brought together more than 50 diverse companies and federal agencies to fund faculty and students to undertake shared research. This led to a transformative tradition of research collaboration among CBPD faculty and students and decision makers from across industry and government."
Soon, a pivotal NSF grant designed the first "industry-university cooperative research centers" focused on the built environment and reinforced the CBPD's critical value. The U.S. General Services Administration (GSA), a long-term research partner, launched its high-performance building initiative in direct response to ongoing ABSIC research.
Throughout its history, the CBPD's collaborative model has been responsive to political and economic realities. "One of the CBPD's strengths," says Associate Professor and CBPD Co-Director Erica Cochran Hameen, "has always been our ability to work with other academic institutions, industry and government — federal, state and local. Because of that long history and our reputation, no matter what's happening in the cycle of economy or government, we can continue the work."
After the 2008 recession, for example, the CBPD proved itself nimble: in partnership with other nearby universities, the Center competed against other research institutions (including the powerhouse state university systems of both New York and California) for a major Department of Energy (DOE) grant to establish a regional hub for energy efficiency research for buildings.
Surprisingly, that five-year research grant went to what Loftness calls "our mid-Atlantic motley crew" — a collaborative team of universities, industries and consultants who set up shop at Philadelphia's Navy Yard and began producing path-breaking research, with Cochran Hameen as the CBPD's boots-on-the-ground leader. Research from that initiative has led decision makers around the globe to understand the costs and benefits of deep energy efficiency, indoor environmental quality, and environmental sustainability.
The need for the CBPD's research on high-performance buildings and communities is only growing. Along with Assistant Professor and CBPD Co-Director Azadeh O. Sawyer, Loftness and Cochran Hameen seek to broaden and deepen the CBPD's leadership in building research.
"We want people to be healthy and to maintain or improve their quality of life," says Cochran Hameen, "and we can do those things while using less energy." She notes that achieving this convergence requires a broad application of the CBPD's knowledge and resources — not only in high-performance, cutting-edge buildings, but also in the built environments we interact with most: workplaces, homes and, crucially, schools.
Pittsburgh is an important place to lead the work on high-performance, low-energy buildings. Its identity as an emerging tech hub is colliding with the aging of its electrical grid, which limits productivity and raises costs. Recent research from CMU's College of Engineering shows that, in many cases, these costs are disproportionately shouldered by the lowest-income Pittsburghers. Cochran Hameen sees great potential in putting the CBPD's extensive knowledge to work in its own backyard, increasing quality of life and lowering costs for our neighbors.
To this end, Cochran Hameen is undertaking new research emblematic of the CBPD's future direction: one current project, funded by CMU's Block Center for Technology and Society and the U.S. Department of Commerce (DOC), seeks to teach students from any background how to perform qualitative and quantitative indoor environmental assessments and suggest retrofits to transform them into healthy, sustainable, energy efficient, and equitable environments.
As they have always done, CBPD faculty continue to work alongside and mentor master's and Ph.D. students, many of whom have gone on to become the world's foremost experts on building performance and energy efficiency. Considering this legacy and the future of genuinely world-changing research, Loftness reflects, "It's genuinely been a privilege."
Siliang Lu (PhD-BPD '19) is putting her experience in the Center for Building Performance and Diagnostics (CBPD) to excellent use.
During her years working with Associate Professor and CBPD Co-Director Erica Cochran Hameen, Lu focused her Building Performance and Diagnostics Ph.D. research on AI-powered HVAC controls. Now, as a researcher in Bosch's corporate research AI department (formerly in the Bosch Center for Artificial Intelligence), she has widened her focus: her professional domain includes mobility and consumer goods, as well as building technology.
The variety in her portfolio is a function of her work environment, says Lu: Bosch Center for AI is a diverse research group responsive to the company's needs at any given time. She, for example, has brought her controls-optimization expertise to the domain of mobility, improving chassis controls of steering, braking and suspension. And after Bosch's recent acquisition of Johnson Controls Hitachi's Residential and Light Commercial HVAC business, the HVAC-controls expertise Lu honed during her time in the CBPD has been called upon again.
Whether designing relatively static systems like HVAC or more dynamic mobility systems, Lu attends to a consistent set of algorithmic considerations. As in her Ph.D. work, she designs reinforcement-learning systems that transform data about occupant perception, occupant sensation, and ambient environment into an optimized experience for each user — whether that user is in a workplace or a vehicle.
The CBPD's interdisciplinary and collaborative research models have prepared Lu to appreciate and rely on both inspiration and challenge from colleagues outside of her own area of expertise. She notes, though, that she "cherishes the deep-learning environment in the Center [for Building Performance and Diagnostics]; while all of my current colleagues are AI specialists, not many have backgrounds in building performance. I'm grateful to have been able to discuss and strengthen my ideas with classmates and colleagues in similar domains to mine, before joining such a diverse work environment."
Lu has retained her connection with Carnegie Mellon Architecture and the CBPD, partly through her interactions with Carnegie Mellon's large alumni network. That network has afforded Lu a host of opportunities, including a position as an adjunct research fellow at NYU Shanghai and connections with academic researchers at multiple Asian universities. She was thrilled, for example, to encounter another CBPD alum during a recent work trip to Singapore.
With building performance and AI controls constantly growing in exigence, Lu is glad to know that the CBPD's research has a global reach. "The power of the work and of our alumni network," she says, "is wonderful."
