Since July 2017 a new acoustic regulation is applicable in France for some buildings undergoing a thermal renovation. The concerned buildings are lodging buildings, educational buildings, healthcare facilities and hotels; more specifically only some room types are covered with acoustic requirements. These acoustic requirements only concern façade sound insulation. Furthermore, the targeted building have to be located in specific noisy environment. This paper describes which thermal renovation implies the respect of this new regulation. The acoustic requirements are then presented for the different situations of the building with respect to outdoor noise condition. In order to select the acoustic performance of some building façade components such as windows, air-inlet, etc…, either a specific acoustic analysis or predefined performance depending on different configurations is required. These predefined performances are presented and examples are given to illustrate the method. Differences with the current regulation for new buildings of the same type concerning sound insulation with respect to outdoor noise is also discussed. Finally, the application guide developed in order to support the implementation of this new acoustic regulation is introduced.
