The OXIVI thermal engineering office assists you in the elaboration of your compulsory energy balance in order to evaluate the energy consumption of the condominiums and to consider its reduction.

Mandatory tertiary energy audit - OXIVI - Article L233-1 of the energy code

Mandatory energy audit for large companies

Large companies with more than 250 employees are obliged to carry out an energy audit in order to implement a concrete energy efficiency strategy for their activities.

Provided for by the European directive 2012/27/EU on energy efficiency, then set by the law n°2013-619 of July 16, 2013 on various provisions of adaptation to European Union law in the field of sustainable development.

An energy audit can lead to savings of up to 30%.


Since 05/12/2015, all large companies must be able to justify :

  • Either to have carried out an energy audit less than 4 years ago according to the requirements of the NF EN 16247 standards and covering at least 80% of the energy bills.
  • Or to be ISO 50 001 certified on at least 80% of energy bills.

What if my ISO 50001 certification is no longer valid?

This means that your company is no longer compliant. To be compliant, you will need to have an energy audit performed within 6 months.

Energy audit and data collection platform

According to Article L233-1 of the French Energy Code, legal entities subject to the energy audit obligation must transmit electronically (support.audit-energie@ademe.fr) the information relating to the implementation of the obligation defined by the Order of May 20, 2016 (amended by the Order of November 15, 2018).

The Energy Performance Diagnostic (ECD) is mandatory for condominiums with less than 50 lots

The energy balance is mandatory for condominiums equipped with a collective heating or cooling system.The energy audit makes it possible, within this framework, to evaluate the annual energy consumption of the building with a view to improving its energy performance.

The nature of the energy balance varies according to the number of lots owned by the condominium.

  • Below 50 lots, an Energy Performance Diagnosis (ECD) must be carried out.
  • From 51 lots, an energy audit is carried out if the building permit was filed before 01/06/2001.

The OXIVI thermal and energy engineering office is in charge of carrying out the Energy Performance Diagnosis (DPE) for buildings and housing within the framework of the thermal regulation RT2012.
