The California Institute of Technology, better known as Caltech, is a revered science and engineering university. Founded in 1891 in what is now Pasadena, the institution has a history of successful scientific research and development. Its faculty, alumni, and postdoctoral scholars have earned 47 Nobel Prizes, and its rocket scientists founded the Jet Propulsion Laboratory, which Caltech continues to manage for NASA. Now, thanks in large part to gifts from billionaire philanthropists Lynda and Steward Resnick, through their foundation and consumer products brand The Wonderful Company, Caltech is on a long-term mission to develop sustainability initiatives. In 2009, the Resnicks, with a matching gift from Gordon and Betty Moore, contributed $30 million to establish the Resnick Sustainability Institute, headed up by director Jonas Peters, Bren Professor of Chemistry at Caltech. The latest salvo is the Resnick Sustainability Center (RSC), part of a $750 million gift the Resnicks made in 2019, at the time, the largest donation ever for environmental sustainability research and the second-largest donation ever given to an academic institution, according to Caltech. The new $133 million RSC, an 80,000-square-foot hub currently housing four research centers, opened in October 2024. It is sited near the western edge of Caltech as a gateway building for all those who approach the campus from the west or the south. The constricted site was selected by the office of Planning, Design and Construction (PD&C), which oversees all new projects on the campus.Caltech wanted a building that would inspire research in four critical areas. (Michael Moran)After a search that included several prestigious national firms, Caltech chose the Yazdani Studio of CannonDesign, led by Mehrdad Yazdani. The selection and design review group included Peters, several Nobel Laureates, PD&C, Bernard Jazzar (the curator of the Lynda and Stewart Resnick Collection, representing the Resnicks), and the City of Pasadena Design Review Commission. Caltech challenged the design team to create a building that would inspire research in four critical areas: Sunlight to Everything, aimed at converting the suns energy into fuels and building more efficient electricity infrastructure; Climate Science, including the lowering of carbon emissions; Global Ecology and Biosphere Engineering, with a goal to help plants adapt to a changing climate and improving water and nutrient use; and Water Resources, with a focus on management and finding improvements in water treatment and reuse.The facade is wrapped in an undulating transparent skin of tilted and curving glass. (Tim Griffith Photography)Water management has a particular resonance for the Resnicks, whose privately held agribusiness The Wonderful Company sells pistachios, almonds, Fiji water, and POM Wonderful pomegranate juice. The company also owns a 57 percent stake in the Kern Water Bank, an underground reservoir in Southern San Joaquin Valley. Beyond other concerns about storage, The Wonderful Company recently weathered accusations of hoarding water during the destructive wildfires around Los Angeles in January. In response, the company issued a statement refuting what it referred to as false claims and stated that it uses less than 1 percent of the states water. Officials and media organizations, including factchecking site Snopes, debunked any conspiracy theories about the Resnicks hindering firefighting efforts. The intent of the RSC is to bring together all six scientific divisions of Caltech to work in a collaborative environment. Most university laboratories serve individual departments, like chemistry, biology, or physics. This building breaks new ground by fostering experimentation and exploration of sustainable concepts. Yazdani told AN, The building does not serve a single department. It is a research hub built around an idea.The architects had to answer the question: What will a building that brings together scientists from diverse disciplines feel like and look like? How will it inspire collaboration, experimentation, and discovery?The curtain wall is supported by timber and a tensile structure. (Tim Griffith Photography)To answer these challenges Yazdani created the ground floor and 4-story atrium that is like a town square, he said. Its a place that draws various disciplines together, allowing a critical exchange of ideas. Currently, four of the six Caltech divisions are already undertaking research in the facility, and there are proposals from the remaining two divisions. It is a building that welcomes ideas from all Caltech disciplines. To foster the concept of sustainability, every freshman takes an introductory course in this building. In addition, the Brinson Exploration Hub has a lab in the building devoted to planetary astronomy. In certain ways, Caltech is conducting an experiment that really hasnt been done before, Peters told AN. We are building an institute that really tries to pull, essentially, all of the campus toward problems and solutions in sustainability. The building is on track to achieve LEED Platinum certification.The architecture sets the tone. The Resnick Sustainability Centers basic design concept is a stack of flexible research labs at the core of the building that are then wrapped in an undulating transparent skin of tilted and curving glass, creating a light-filled atrium for collaboration and innovation.Research labs have virtually no vibration. (Chris Flynn Photography)Structurally, the building is a hybrid, with mass timber columns and slabs that wrap a reinforced concrete core, creating research labs with virtually no vibration and the ability to withstand potential earthquakes. Rooftop photovoltaic arrays generate power for the building, and native plants and stormwater drywells are part of a larger sustainability effort. Announcements about the RSC noted that photosynthesis served as inspiration for the project, and offsetting carbon emissions is a theme of the landscape concept, with carbon-sequestering trees and shrubs figuring into the design.The curtain wall of the RSC is supported by a mix of timber elements and a tensile structure. The exterior of the curved, sloping, cold-bent glass is highlighted by strips of aluminum. Multiple light studies were done to create the luminous space. Its like a cathedral, but for science, Peters exclaimed.Multiple light studies were done to create the luminous space. (Michael Moran)Another key feature is the buildings breezeway, which runs north south and separates the Resnick Sustainability Center from the Noyes Lab. The space invites Caltech students and facultyand even the publicto witness in-progress research.Yazdani explained: Bringing every Caltech student into this space puts an emphasis on how integral sustainability is to all the disciplines they will encounter throughout their education at Caltech.Sketches of the Resnick Sustainability Center at Caltech (Yazdani Studio of CannonDesign)The breezeway also opens access between the southern campus and the newly restored Beckman Lawn to the north, with spectacular views of the San Gabriel Mountains. To attract visitors, a portion of the curtain wall wrapper bends out away from the southern facade, creating a shaded porch. Leandra Davis, executive director of Planning, Design and Construction, said, You get a little taste of the building from the south campus.Yazdanis designs often dont reveal the whole story at first glance. Instead, they beckon visitors inside to learn more. At Caltech, the curved glass exterior not only wraps the 4-story atrium, but it also encloses several research labs and circulation spaces on the third floor, which creates layers of transparency and allows natural light to flow into the building. The move will hopefully inspire bright minds to develop solutions to help us respond to the climate crisis.Michael Franklin Ross is president of MFR Consulting Architects.An educator and architectural journalist, Ross has published over 90 articles and taught at USC, SCI-Arc, and UCLA.
