Holder of a degree in Architectural Engineering, Sébastien has developed a strong interest in sustainable development and wrote his final dissertation on the design of adaptable structures. During his 10 years of professional career as a sustainability consultant and a building services engineer, he has worked on a large variety of projects in Belgium and New Zealand. He has developed strong technical, organisational and communication skills. These years have led him to the question he is investigating today: “How to facilitate the re-use of building services in office buildings undergoing refurbishment?”.


Sébastien Loreau is a PhD candidate at the Université catholique de Louvain in Belgium. He is affiliated with the Faculty of Architecture, Architectural Engineering and Urban Planning. He joined in February 2021 to start his research project entitled RESERVICE.

The project investigates the feasibility and the effects of reusing building services in office buildings. It is an applied research project involving Cenergie, an engineering consultancy in Belgium, as an industrial partner. The project is under the supervision of Prof. André Stephan at the Université catholique de Louvain, who is an international expert in life cycle assessment, Prof. Daniel Cooper at the University of Michigan, who is an international expert in material flow analysis, and Anne-Laure Maerckx, who is a senior consultant at Cenergie. The project is funded by Innoviris, which is the Brussels Region’s public institution for research and innovation.

Sébastien graduated in 2010 as an architectural engineer from the Université Libre de Bruxelles in Belgium. He was introduced to circular economy principles during his master’s thesis, undertaken under the supervision of Dr. Caroline Henrotay. After his graduation, he joined JZH, an engineering consultancy in Belgium, as a building services engineer. For seven years, he developed strong technical and commercial autonomy in his field. Eager for a new challenge, he then moved to New Zealand where he joined WSP, a worldwide renowned engineering consultancy. He gained a new perspective on the field of building services engineering and developed the willingness to investigate the application of circular economy principles to building services. Before starting his PhD, he worked for two years as a sustainable construction consultant at 3E, an international engineering consultancy, where he acquired knowledge of life cycle assessment methods.

In his personal life, Sébastien likes to travel and do sport. He has visited many places including New Zealand, Colombia, Nepal, etc. He has been playing hockey since he was five years old. He currently plays for the hockey club Ombrage in Brussels.
