Alexander Hollberg

Alexander Hollberg is an Associate Professor in the Division of Building Technology at Chalmers University of Technology, within the School of Architecture and Civil Engineering. His academic role focuses on Computational Sustainable Design, emphasizing the development of digital tools for sustainable building and urban design. He holds a PhD in Parametric Life Cycle Assessment (2016) from Bauhaus University Weimar, an MSc in Architectural Engineering (2011), and a BSc in Civil Engineering (2008) from Technical University of Munich (TUM).

His research interests include Sustainable Design Optimization, Stakeholder Interaction, Artificial Intelligence, and Life Cycle Assessment (LCA). He co-founded CAALA, a software and consulting startup in Munich, Germany, advancing tools for real-time environmental performance evaluation in early design stages.

Recent work includes studies on digital twins for urban planning, robust renovation strategies, and AI-driven facade optimization. Hollberg was promoted to Docent (Associate Professor) in Computational Sustainable Design in 2022, focusing on bridging computational methods with sustainable environmental transitions. His collaborative projects address tool development for stakeholder engagement, BIM integration, and circular economy frameworks in construction.

Key Projects:

• Development of Bombyx and Twinable tools for real-time LCA and urban simulation
• Leading the Nordic Build-LCA PhD forum and BIM-based LCSA applications
• Contributions to IEA EBC Annex 72 guidelines on life cycle environmental impacts

Education Background:

• PhD in Parametric Life Cycle Assessment, Bauhaus University Weimar, 2016
• MSc in Architectural Engineering, Bauhaus University Weimar, 2011
• BSc in Civil Engineering, Technical University of Munich, 2008

His research outputs prioritize early design-stage decision support through parametric modeling and AI, with a focus on carbon neutrality and material circularity in construction.
