Daylight is not only considered as a renewable energy: it is also seen as a structuring element of the project. The specific treatment of direct and diffuse flows, and the integration with artificial light are addressed in close collaboration with the architects, in order to best serve the users requirements.


The DIAL+Lighting software, developed entirely by Estia, is a reference tool for major French engineering firms to simulate daylight factors values and daylighting autonomy.
