Electromagnetic field measurements in La Rochelle.

In La Rochelle, the electrical installations of the port sector, the distribution substations of the dense urban fabric and the equipment of hotel and university developments make up a set of low-frequency sources to be characterised under real conditions. Rehabilitation works in the historic centre regularly lead to creating dwellings in immediate proximity to existing technical rooms. ARKENOR conducts the on-site measurement, at low frequencies and in radiofrequencies, and delivers an independent third-party report enabling the enhanced thresholds of certification frameworks to be justified.

In La Rochelle, electromagnetic field measurement establishes the real exposure of a site objectively: low frequencies at 50 Hz near distribution networks and transformer substations, radiofrequencies around transmitters. It positions the results against the regulatory reference levels and documents the "electromagnetic waves" criterion valued in HQE and NF Habitat certification.

FAQ

FAQ, electromagnetic field measurements in La Rochelle

Two distinct domains. In low frequencies (50 Hz), the electric field in kV/m and the magnetic field in µT, associated with distribution networks, transformer substations, rising mains and internal installations. In radiofrequencies, from 9 kHz to 300 GHz, the electric field in V/m, associated with telecommunications transmitters. Each domain has its own protocol and calibrated equipment.
The reference levels come from European recommendation 1999/519/EC, transposed by decree no. 2002-775: 5 kV/m and 100 µT at 50 Hz, and 28 to 61 V/m in radiofrequencies depending on the band. Certification frameworks value more demanding thresholds: 5 V/m and 0.4 µT, then an enhanced tier at 1.5 V/m and 0.2 µT.
No, it is not a general building requirement. It comes into play as an item of evidence within certification frameworks, notably HQE Bâtiment Durable ("electromagnetic waves" theme, formerly target 12) and NF Habitat HQE, where it is a value-adding criterion rather than an absolute prerequisite. We act as an independent third party.
