Building Acoustics
Nîmes, Occitania

In Nîmes, a heritage city with a hot Mediterranean climate, the refurbishment of the old centre and the new developments of Les Costières combine acoustic constraints: old separating walls to be reworked, close party walls and noisy premises at the foot of buildings. The proximity of the A9, the high-speed line and classified infrastructure demands sized façade sound insulation. As across the whole Mediterranean arc, the proliferation of outdoor heat pumps exposes projects to noise emergence disputes. An acoustic study from the design stage secures the insulation, equipment acoustics and the works completion certificate in Nîmes.

In Nîmes, urban density, the widespread use of outdoor heat pumps and neighbourhood noise nuisance make the acoustic study decisive: from the design stage, to size the sound insulation and avoid disputes at handover, then at acceptance, to certify NRA compliance and regulatory noise emergence.
