EnergyGuarded hot box
The CSTB installed the guarded hot box in 2016 at its facility in Marne-La-Vallée, in a 290 square-meter space.
This system assesses the thermal performance of opaque and glazed walls, at full scale and accommodates configurations representative of the way they will actually be used in buildings. Coupled with digital simulation, the results can be used to make usage recommendations for professionals.
The guarded hot box provides precise measurements that can guide the development of new insulation products and techniques, in a context of stricter energy requirements, with a long-term guarantee of in situ performance.
