The Vizcab patent

As part of his research and teaching at EPFL Lausanne, Thomas Jusselme has published a method for creating technical design solutions that meet specific performance objectives for a building. The method involves selecting a design model and parameters from databases, generating design alternatives, evaluating their impact on building performance from another database, and finally ranking the design parameters according to their contribution to performance.

This has been enshrined in a patent held by EPFL, which Vizcab has exclusive rights to use.

Thomas Jusselme

Thomas Jusselme, co-founder of Vizcab, is an environmental engineer with a passion for nature and sustainable construction. After earning a Master’s in Industrial Design from Université Technologique de Compiègne, he traveled across 25 countries with Guillaume Lafont to explore best practices in sustainable building. This journey inspired them to co-found Vizcab in 2015.

Alongside his work at Vizcab, Thomas has been deeply involved in academia. He has taught and conducted research at ENSAG, ENSAL, and EPFL, where he led the Building2050 research program. He earned a PhD from EPFL in 2020, focusing on LCA-based methods for low-carbon buildings. Since 2019, he has been a Professor of Building Energy Efficiency at HEIA Fribourg and the Smart Living Lab, with over 60 scientific publications to his name.

Guillaume Lafont

Guillaume Lafont, co-founder and Managing Director of Vizcab, has a dual background in engineering (environmental engineering at Lyon 1) and entrepreneurship (EM Lyon). He partnered with Thomas Jusselme in 2006 to launch exndo architectures and Milieu Studio, an engineering firm specializing in eco-design and building physics.

In 2015, alongside Thomas Jusselme and Michel Forgue, he co-founded Vizcab.io to help construction and real estate professionals accelerate their carbon transition while optimizing costs. His vision is to empower industry players—developers, architects, and manufacturers—to leverage carbon data for better decision-making.

We believe that digital technology and data science have the potential to catalyse the energy-carbon transition in the building industry, making it profitable for the whole sector

Technology transfer carried out with EPFL

Vizcab originates from a technology transfer out of the EPFL Building 2050 research group, led by our co-founder Thomas Jusselme and hosted at the Smart Living Lab.

We thank the project team — including Human-IST UNIFR, EPFL, and EPFL-ECAL Lab — and in particular Prof. Lalanne and Dr. Tuor, for their contributions to the data visualization work carried out at EPFL.
Their input was a key inspiration for the design of the Vizcab interface.

We are also proud to have received support from the French Investment for the Future Program (Programme d’Investissements d’Avenir).

Finally, we joined UR Link, the Unibail-Rodamco-Westfield incubator, where we developed the MVP of Vizcab.
