Energy and environmental regulations: what are the main measures and in what ways should you comply with them?

Book a demo

In response to climate change, a legislative framework has been built over the years

with a view to developing new energies, but also to promoting energy efficiency and energy savings.

The constantly evolving energy and environmental regulations oblige many economic actors to apply a set of measures, particularly focused on the reduction of energy consumption in buildings. To answer the environmental stakes of the organizations, Energisme has solutions dedicated to the acceleration of the energy transition of buildings.

Energy and environmental regulations: what rules will apply in 2021?

Energy performance represents no less than 20 years of environmental regulation

  • 1997 to 2010: Kyoto Accord, Directive on the energy performance of buildings, Programming Law setting the objectives for energy performance, European Directive on energy efficiency, European Energy and Climate Package 3*20, Grenelle Law.
  • 2010 to 2015: environmental conference on sustainable development, Housing Energy Renovation Plan, European Climate Energy 2030 package, Energy Transition Law for Green Growth.

Directives are issued at both the European and French levels, targeting all economic actors.

quelles sont les règles en vigueur en 2021

Key European regulations

Buildings are often at the center of the preoccupations regarding thermal regulations which have evolved continuously since the 1970s. RT 1974 following the first oil crisis, RT 1982, RT1988, RT2000, RT2005 (introducing the BBC – Bâtiment Basse Consommation – label) and RT2012 (former BBC – Bâtiment Basse Consommation – label)… All these evolutions meet a common objective: to reduce the energy consumption of buildings

From now on, RT2012 will be replaced by the future environmental regulation (RE 2020) for more responsible buildings. Less energy consuming, the construction of new buildings will have to respond to climate change by having a reduced carbon footprint. Taking into account the carbon footprint of buildings, which today account for 20% of greenhouse gas emissions in France, is the major innovation of the RE2020. This is essential to ensure the continuous improvement of the energy performance of buildings, but also to guarantee the comfort of occupants during heat waves, which are likely to become more frequent.

Good to know : the RE2020 was introduced by the ELAN law (Evolution of Housing, Development and Numerical), to which we owe the Tertiary Decree and the BACS Decree. These regulations are designed to help obliged players achieve their energy saving objectives..

Regulations at the national level

In 2015, France adopted the National Low-Carbon Strategy (SNBC) to combat climate change. Introduced by the Law on Energy Transition for Green Growth (LTECV), it sets short- and medium-term objectives to significantly reduce greenhouse gas (GHG) emissions until carbon neutrality is achieved by 2050.

All public decision-makers and sectors of activity are concerned as it aims to:
  • Zero emissions for energy production.
  • Zero GHG emissions from buildings.
  • Zero GHG emissions for transportation (except for domestic air transport).
  • 66% reduction in GHG emissions from waste.
  • 46% reduction in GHG emissions from agriculture.
  • 81% reduction in GHG emissions from industry.
Energisme supports you

Energisme supports you in achieving your environmental objectives through an energy management platform. The solution collects data from multiple data sources, ensures their interoperability and restitutes them in the form of dashboards adapted to your regulatory obligations (Tertiary Decree, BACS, GHG Emissions Assessment, etc.). 

Energy regulation of buildings: what is at stake?

For the building industry (new construction, energy renovation), the issue is first and foremost environmental, since the depletion of fossil fuels and their impact implies a transition to renewable energy.

The issue is also financial, since achieving the objectives also aims to reduce energy consumption and limit waste.

Finally, the issue is regulatory, as all building actors must comply with the future regulations that determine the new standards for efficient buildings, namely to :

Meet the requirements of high energy and environmental performance, including the construction of positive energy buildings (BEPOS) and the use of renewable energy
Control costs related to the life cycle of buildings, by calculating energy consumption, environmental impacts, waste recycling, or the impact of energy renovation of buildings
Calculate greenhouse gas emissions.

What measures should be implemented to comply with energy and environmental regulations?

In order to meet the ecological and environmental regulatory requirements , Energisme has developed the N’Gage energy management platform. The solution centralizes the energy and environmental data of a park in order to visualize the multi-fluid consumption and to improve the energy performance of the buildings. You can get an accurate and up-to-date energy analysis of your facilities in real time.

As a true partner in your energy transition, you can manage the energy performance of your entire fleet from a single interface, to harmonize and make your reporting more reliable.
