NF 31-080
The standard NF 31-080 deals with the acoustic quality of offices and associated spaces: individual office, office building, open space, pan to develop, meeting room, relaxation area, restaurant and traffic.So far, there are no normative reference French in comfort and surround sound in the workspace.
The standard NF S 31-080 establishes a repository for technical dialogue and a formal commitment between the various actors involved in the design and implementation of a project office or space associated. It provides assistance in the drafting of specifications, design, implementation and receipt books.
The standard applies to the new buildings, renovations and changes to the allocation of spaces, ie for different types of spaces found in office buildings but does not describe the building as a whole.
For construction of office building, the acoustics must be integrated early in the design.
Current Level: Refers to the minimum functional level, do not ensure acoustic comfort.
Level Performance: This level provides acoustic comfort conducive to work, going beyond the standard "current".
Level Very Powerful: Corresponds to maximum noise levels made possible by the action on all elements of the building structure. This level aims to improve communication useful and removing unnecessary noises.
For each type of premises, the standard sets for each of these three levels of objectives of the numerical results easily verifiable (external and internal isolation, reverberation time, noise level, and decrease noise) to validate the quality of the building.
