Luisa Caldas is Professor of Architecture at UC Berkeley. An architect by training, she 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. Her work focuses on the use of advanced computational tools to support the deployment of environmental factors into early architecture design stages. A main area of research is the integration of challenging, 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 envelope components.
As part of her Design Technologies Initiative, Professor Caldas recently founded the new AR/VR Lab in the Department of Architecture, dedicated to the study of Augmented Reality and Virtual Reality applications to architecture. Apart from offering several courses in this new field, her research focuses on use of immersive environments for parametric building design and simulation, with a particular focus on daylighting. She is a member of the Center for Augmented Cognition at UC Berkeley.
Additionally, Caldas research applies advanced energy simulation tools in the context of generative design environments. She is the author of GENE_ARCH, the first generative design system that integrated Energy Plus as a simulation engine, and used Pareto Genetic Algorithms for search and generation of energy efficient buildings by simultaneously optimizing thermal and lighting energy patterns. GENE_ARCH currently integrates other simulation engines, such as Radiance and Daysim. Recent software development includes Painting with Light, a user-guided interactive evolutionary system for daylighting design, that allows architects to use color to specify desired light levels in space and searches for building geometry and materials that bring the design close to those performance targets, and Sun_Carve, for direct light design.
