To solve a building problem or a physical disorder, the Estia approach is to make an extended diagnosis using a wide range of sophisticated instruments (infrared camera, temperatures and humidity sensors, CO2 detector, Blower-Door, fish-eye camera, luminancemeter, reflectometer, luxmeter, etc.). The collected information are supplemented by the analysis of the construction details and are also validated by numerical simulation.

Our proximity with Solar Energy Labortory (LESO-PB) allows us to use the EPFL equipment when necessary (artificial sky, heliodon).
