Luisa Caldas is Professor in the Department of Architecture and director of the XR Lab. She holds a PhD in Architecture and Building Technology from MIT and a MSc from the Bartlett Graduate School, University College London. Caldas received her professional architecture degree from the University of Lisbon and practiced as a licensed architect before becoming a researcher, educator and immersive environments creator.
Caldas has held teaching or visiting research appoitments at MIT, Tokyo Institute of Technology, University of Lisbon, PUC Chile, Universidade do Minho and Frederico Santa Maria Technical Univesity. Prior to coming to Berkeley in 2012 she was Professor at the School of Architecture of the University of Lisbon. She was previously the Head of the Architecture course of the School of Engineering of the University of Lisbon. Caldas was also a Fulbright scholar and a member of the MIT Portugal program.
At Berkeley Caldas founded and directs the XR Lab - Virtual, Augmented and Mixed Reality Laboratory at UC Berkeley. The lab's research focuses on the use of immersive environments for building design and simulation, healthcare design, ADA, parametric and generative design, UI/UX, narrative and storytelling. Teaching students new modes of communication and representation in immersive enviroments is also a major focus of the lab. She is a member of the HTC Center for Enhanced Reality at UC Berkeley.
The XR Lab most recent project is Virtual Bauer Wurster, a multiplayer remote collaboration platform in Virtual Reality. Another recent production is the Rupp Prize exhibition Building for a Decarceration Nation, by Deanna van Buren.
Caldas is the creator of BAMPFA AR, an Augmented Reality project for the Berkeley Art Museum and Pacific Film Archive, focusing on the history and construction of the new museum building by Diller Scofidio + Renfro. Media coverage of BAMPFA AR include the Architect's Newspaper, the Daily Californian and ArtForum Magazine.
Luisa Caldas has been active for more than twenty years in the field of sustainable design and green building, both in academia and as an energy consultant for large commercial buildings. She was the principal of SoftEnergies, an energy consulting company, for over 10 years. Her sustainability research work focuses on the use of advanced computational tools to support sustainability input in early design decision making. One of her main areas of research in this field is the integration of complex geometry architectural solutions with sustainability, by developing the conceptual processes, workflows, and computational tools that allow multiple scale integration, from master planning to building design to facade components.
Caldas research is also directed to the field of generative design systems. She is the author of GENE_ARCH, the first generative design system developed for search and generation of energy efficient buildings, integrating Energy Plus as a simulation engine. GENE_ARCH currently includes other simulation engines, such as Radiance and Daysim. Recent software developments include Painting with Light, a user-guided interactive system for daylighting design that allows architects to use color to specify desired daylight levels in space and then searches for building geometry and materials to achieve those goals; and Sun_Carve, a software that informs architects where to carve openings in buildings to capture sun and minimize energy use.
