As an implementation of the Directive 2010/31/EU on the energy performance of buildings, French public authorities have requested that persons performing energy performance diagnosis, be certified by an accredited CAB. The assurance that operators are competent to achieve expected controls is in keeping with the general pattern regarding energy efficiency and transition. This accredited certification of persons is mandatory in France since 1st November 2007 and has been updated since then in order to take into account the EU directive.
Accreditation contributes to a better transparency for end-users, making easier their awareness in transactions, e.g. on energy expenditure while renting or buying an accommodation and the consecutive carbon impact on the environment.
