A research engineer at Saint-Gobain Recherche since 2010, Marine is working on several studies in the natural light field (Daylighting).

"We are conducting several studies on the various aspects of daylight," Marine explains.



"Firstly, the new thermal regulations for buildings require a lower overall consumption of heating, air conditioning and artificial lighting. We are thus working on how to improve the natural light of buildings in order to improve energy efficiency."

Then, for a number of years, research has taken users' comfort into account. "If the natural lighting of buildings has not been designed according to the human factor, it loses in performance. Now we are trying to understand how building materials can improve the distribution of natural lighting within buildings." Today, the health factor is very important. "We realise that people need natural light for their well-being. The physiological aspect is therefore taken into account in our research." The research team in which Marine works, specialising in optics, thus seeks to understand the basics of visual comfort.

"Daylighting is at the crossroads of several disciplines. We work with Saint-Gobain Recherche's teams who are responsible for the thermal aspect. We also organised a workshop bringing together people from both research and marketing, working for Saint-Gobain's various activities, to compile a report of the current situation and come up with ways of optimising building materials and glazing enabling them to more effectively bring natural light into buildings."

In addition, partnerships have been concluded with universities, in particular to study aspects related to the concept of visual comfort and architecture. "Our goal is to design new products that provide improved visual comfort and better energy efficiency."
