Expertise and experience

The Solar Energy and Building Physics Laboratory (LESO-PB) is one of the centres of expertise of the Institute of Building Technology of the Swiss Federal Institute of Technology in Lausanne (EPFL) Swiss Federal Institute of Technology in Lausanne (EPFL). Founded in 1974, it employs more than 35 30 lecturers and researchers and is active in the domain of building technology and science. The Laboratory is responsible for the co-ordination of numerous teaching activities in building physics at the EPFL and puts particular emphasis on high level scientific research with promising practical application potential. The priority research axes of the LESO-PB/EPFL are: daylighting, energy and colours; indoor environment quality and health; retrofit and refurbishment strategies; renewable energies - Integration of photo-voltaics; building integrated technologies and computer expert systems. The Laboratory is establishing itself as a national centre of excellence in building diagnosis, renovation, rehabilitation and conversion of buildings as well as in architecture and sustainable development.
For this research programme, the EPFL is especially skilled in measurement techniques, planning of experiments, interpretation techniques and data handling (The DREAM database was developed by the LESO-EPFL by people who later funded E4Tech). The staff of about 30 physicists, architects and engineers brings the interdisciplinary and multi-professional know-how necessary in this kind of research project.

Key persons

Claude-Alain Roulet, physicist, is specialised in building physics and building energy, indoor environment quality, as well for modelling as for measurement techniques. He is leading a research group on Indoor Environment Quality. He gives lectures in (building) physics at EPFL since 1966. He is member of ISIAQ and is Swiss delegate to the CEN Technical Committee 89 "Thermal performance of buildings", where he convenes the working group 4, which is in charge of standards related to energy in buildings. He is (co)-author of many scientific publications, books and teaching handbooks. He directly contributed to the following international programmes: IEA-ECB annex 20 Airflow patterns within buildings; IEA ECB annex 23 Multizone infiltration modelling; IEA ECB annex 26 Ventilation in large enclosures; European Indoor Air Quality Audit; Joule PASCOOL, OFFICE, TOBUS, AIRLESS, InvestImmo and UrbVent European projects.
