Ease of assembly and wind resistance are studied using test benches located at Sophia Antipolis and Marne-la-Vallée, respectively.

Go-No Go controls: control of the part by U-shaped blocks controlling the position of the different components of the part by mountability

Thermal, photovoltaic and hybrid solar panel systems installed on roofs: the CSTB laboratory tests their ease of assembly at full-scale using a special test bench.

Check the consistency of the digital model (no interference modeling inconsistency, ..) and the requirements (allocated volume, mass, interfaces, mounting ability, etc ...) on lots of studies concerned
