Summer Comfort


Our approach combines a suitable design of the openings, a good management of solar gains, and the activation of the building thermal mass. This approach is often complemented by the implementation of simple and robust automation that allow to optimize the potential for passive cooling.

The Estia teams have developed specific simulation tools allowing us to systematically propose detailed parametric studies. ("Estia-g", "DIAL+Cooling").

Some emblematic projects
