Short biography

Nicolas Réhault was born in 1973 in France and studied acoustical, thermal and lighting engineering at the Ecole Supérieure d´Ingéniers de Poitiers. From 1998 until 2009, he has worked as a project engineer in the fields of building acoustics, heating, ventilation and air conditioning in companies located in France, Germany and Switzerland. In 2009, he started as a scientist at Fraunhofer ISE and has been leading the group Building Performance Optimization since 2012. He is coordinator of several German and international research projects in the field of energy efficiency in buildings. His research focus is on the development of practicable methods and tools to support the supervision and the optimization of the energy operation of buildings.
