Daniel Kellenberger studied cultural engineering at the ETH and later trained part-time as an environmental engineer at the FHNW. Thanks to this further training, he had the opportunity to contribute to the development of the internationally renowned life cycle assessment database Ecoinvent at EMPA. He was responsible for collecting data on mineral building materials. He was then able to apply the expertise he had acquired in life cycle assessment methods at the building material, component, building, site and community levels, as well as in product design.
After many years in a consultancy office in Zurich and a mandate as national project manager and regional manager for the 2000-watt sites on behalf of the Swiss Federal Office of Energy, he took the step back to university. Since the end of 2022, he has been Professor of Sustainable Building – Life Cycle Assessment at the Institute for Energy and Sustainability in Building (INEB) at the School of Architecture, Civil Engineering and Geomatics (HABG) at the University of Applied Sciences and Arts Northwestern Switzerland (FHNW) in Muttenz. As an employee of the HABG, he was asked by the former director to continue the Building and Planning Table of both Basel and to take over the coordination.
