Rapid development of means of communication (cell phones and Wi-Fi), LEDs and infrared detectors have led to increased exposure for the users of the construction and urban development sectors. Not only have these waves fundamentally changed our habits, they provide us with convenience and safety, but they also represent a potential or confirmed risk that must be assessed and quantified.
The CSTB, thanks to its advanced knowledge in these fields, enables you to assess the extent of the risk and to maximise comfort. The Institute's expertise ranges from evaluating innovative materials to measuring exposure at the urban scale, from the upstream phase of projects to industrial operation and maintenance.
The CSTB guides you in the precise characterization and optimization of materials, lighting systems or systems interacting with the electromagnetic environment, such as antennas, etc. Thanks to its digital and experimental tools, the CSTB specializes in the following areas of expertise:
- optimization of visual comfort through natural or artificial lighting (PHANIE tool)
photorealistic and false-color prediction of lighting in complex volumes, such as performance halls, museums, etc.) / Visual ergonomics and assessments of the contribution of natural lighting / Combination of natural and artificial lighting in structures / Impact on sunlight exposure of high rises / Propagation of light in dispersive media, such as smoke, fog, etc.
- development of occupancy sensors (infrared)
design of complex optical systems / Assessments of the efficiency of presence sensors / Virtual system simulation
- propagation of radio frequencies and exposure modeling
Wi-Fi coverage and exposure in complex indoor spaces such as train stations, airports, etc. / Predictive mapping of exposure to radio-frequency waves in urban environments
- Photogoniometer and Bidirectional Reflectance Distribution Function (BRDF) Measurement Facility
- Phéline Platform: study of electromagnetic properties in controlled environments
- Advanced digital simulation tools: PHANIE (prediction of indoor and outdoor lighting environments, via the hierarchical radiosity method) / ICARE-RF (electromagnetic propagation in complex 3D environments, based on the beam-tracing method) / MITHRA-REM (predictive mapping of exposure to waves at the urban level)
