France

Summary

The RT2012 sets rigorous performance expectations, requiring that residential and non-residential buildings use a maximum of 40-65kWh/m2/pa depending on locality and altitude of the building. The code is a performance-based code that requires projects to show compliance with the maximum primary energy consumption called the ‘Cepmax’ coefficient. It is the maximum conventional consumption of primary energy that considers thermal envelope components and most energy consuming systems including, HVAC, hot water, lighting, heat recovery and auxiliary systems.

France has had prescriptive building energy efficiency requirement since 1955. The first performance based standard was implemented in 2005 following the release of the EPBD requirements in 2002. The RT2012 reflect the demands of the EPBD recast, with compliant buildings aiming to be approximately 40% more efficient than buildings built according to the 2005 regulations. As a result the code includes many dynamic requirements in order for this performance frame to be achieved, including mandatory renewable energy requirements, mandatory computer simulation, mandatory air-tightness testing for residential buildings, bio-climatic design considerations, extensive training of assessors, well established labeling and certification schemes and a target to build energy positive buildings by 2020.

Code History and Future Targets

General Process in Setting Requirements:

  • How far in advance are future targets set?:
    2020
  • Stakeholders are informed of future targets far in advance

Zero Energy Targets:

  • All end uses are included
  • There is not a realistic roadmap in place
  • National Target date for nZEB:
    By 2020 all new buildings should be energy-positive.
  • Special Requirements for public buildings:
    In March 2007, the French Government published the decree and in December 2007 the order regulations, in order to define the implementation of the Energy Performance Certificate. For all public buildings, energy consumption is evaluated based on the energy use invoices of the last 3 years. The expert has to make recommendations for improvements, and also for better management of the building and its equipment.
