The Solar Energy and Building Physics Laboratory (LESO-PB) works at the forefront of research and technological development in renewable energy, building science and urban physics. It is part of the School of Architecture, Civil and Environmental Engineering (ENAC) of the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland.
The Laboratory is located in an experimental building on the EPFL campus where a staff of more than fourty scientists and technicians collaborate under the direction of Prof. Dr Jean-Louis Scartezzini and four group leaders.
The LESO-PB has acquired a solid national and international reputation in the academic world through the generation and transfer of advanced scientific knowledge geared to the requirements of the built environment and sustainable development.
The Laboratory works on the implementation of advanced technology in buildings inspired by living organisms (bio-mimetic approach) and nano science, designs and sets up experimental equipment for renewable energy use (photovoltaics, daylighting, solar thermal design, etc.) and develops building operation strategies that optimise energy use and enhance indoor environment quality and health.
LESO-PB personnel tasks include teaching to undergraduate and postgraduate students of architecture, civil and environmental engineering, physics as well as other EPFL sections, who can choose to do their Bachelor or Master thesis at the Laboratory.
Scientific activities of the LESO-PB include basic and applied research in the following fields:
• Intensive use and perception of daylight
• Indoor environment quality and health
• Complex urban systems
• Smart buildings / Smart cities
• Renewables integration in the urban environment
• Nanotechnology for solar energy applications
Research is carried out in the context of national and international collaboration with renowned academic institutions and industrial partners (National Research Programmes, European Framework Programmes, International Energy Agency). Results are widely published in scientific journals.
Transfer of novel technology and scientific knowledge to practice is ensured through publications, postgraduate courses, industrial applications (patents and spin-off companies) and development of software for design and analyses in the domain of building science, urban physics as well as renewable energy.
Every two years, the Laboratory organises the CISBAT Conference, an international platform for the presentation of advances in sustainable building.
And once every month, the public is invited to a Leso Lunchtime Lecture on subjects related to the Lab’s activities and interests.
