CISBAT 2021 International Scientific Conference

8-10 September 2021, EPFL, Lausanne, Switzerland

Digitalisation, machine learning and smart materials offer a whole new toolset for the decarbonisation of the built environment. At CISBAT 2021, specialists in these domains connect with building scientists focused on energy efficiency, renewables, circular economy and human comfort and health to bring the building sector closer to the carbon emission and energy efficiency targets it so urgently needs to meet.

We are delighted to invite researchers and stake holders who, from nano to urban scale, actively work toward more sustainable buildings and cities, for three days of scientific knowledge exchange and networking at EPFL in Switzerland – face to face or online.

8. Data mining for the built environment (big data & machine learning)
9. Urban climate modelling (microclimate, energy performance, regenerative design)
10. Innovative construction for circular economy (LCA, recycling, design)


  • Two days of topical sessions covering a wide range of research projects (200 papers to be published in Journal of Physics: Conference Series) with special sessions chaired by IBPSA Switzerland and IEA EBC Annex 79.
  • A roundtable focused on Cities on their Way to Carbon Neutrality: Approaches beyond Myths and Political Greenwashing
  • Workshops on AI for the built environment, Building simulation, the EnerMaps open data tool and Innovations to accelerate the renovation wave.
  • Topical visits on the EPFL campuses Lausanne and Fribourg.
  • An evening dinner cruise on Lake Geneva, and plenty of other occasions for networking.
  • An excellent virtual conference platform to make the conference a pleasant experience for on-site and online participants alike.

Detailed information and conference registration:

Based on a partnership with, CISBAT 2021 will be carbon neutral. Offset of CO2 emissions (including due to participants' travel and lodging, infrastructure, meals etc.) will benefit high-quality myclimate climate protection projects. Generally, care will be taken to keep CISBAT’s environmental footprint to a minimum.
