Alexander Hollberg

Associate Professor at Building Technology

Alexander Hollberg is Associate Professor in the research group Sustainable Building, Division of Building Technology, at Chalmers. Alexander specialized in Computational Sustainable Design to work on developing methods and tools that facilitate the design of sustainable buildings and cities. The digital tools are used to assess, optimize, and visualize the design’s performance in real-time (energy, LCA, LCC, daylight, etc.). The goal is to provide decision-makers with the necessary information in the early design stages. Furthermore, he is co-founder and Head of R&D at CAALA, a software and consulting startup based in Munich, Germany.
