Raphaël Compagnon


Dr. Compagnon is currently with the Département d'Architecture at the Ecole d'Ingénieurs de Fribourg, Switzerland.

Raphaël Compagnon recently spent one year as a visiting associate at the Martin Centre for Architectural and Urban Studies, University of Cambridge (UK). Prior to that, he did research and teaching for ten years at the Laboratoire d'Energie Solaire et de Physique du Bâtiment (Solar Energy and Building Physics Laboratory) at EPFL in Lausanne (Switzerland).

He graduated in Physics from the Ecole Polytechnique Fédérale de Lausanne (EPFL) and earned his PhD for his thesis entitled: "Simulations numériques de systèmes d'éclairage naturel à pénétration latérale" (Numerical simulations of daylighting systems for side-lighting).


Intensive and sometimes critical use of Radiance since 1990. Integration of an algorithm for the calculation of luminous transmission through prismatic elements used for daylighting systems. Validation of parts of the software. Development of a translator between the Scribe-Modeller CAD program and two daylighting simulation tools (among them Radiance) that is now part of the ADELINE software package. Development of a tutorial entitled "RADIANCE: a simulation tool for daylighting systems".
