Electromagnetic field measurements in Cergy.

In Cergy, the housing stock from the new town has a homogeneous technical layout, with transformer substations and rising mains of the same generation, often integrated into buildings according to repeated construction principles. This homogeneity makes it possible to reason by typology during measurement campaigns across a portfolio. The rail infrastructure serving the town forms a second family of sources. ARKENOR carries out the measurement at low frequencies and in radiofrequencies as an independent third party, and delivers a report usable for certification.

In Cergy, 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 Cergy

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.
