The RE 2020 is the new energy and environmental regulations for all new construction. It introduces environmental performance in new construction via life cycle analysis. 

The RE2020 applies in several stages:
- initially, it concerns: individual houses and collective housing;
- secondly, it concerns: primary and secondary education offices and buildings;
- in a third step, it concerns specific tertiary buildings: hotels, shops, gymnasiums.

RE is broken down broadly into three areas: energy; comfort and carbon. ‘Energy’ relates mainly to the energy consumption required while the building is in operation, which is now based on CO2 emissions rather than kilowatt hours. This is referred to as ‘energy carbon impact’ in RE2020. ‘Comfort’ refers to the amount of discomfort permitted in hot weather. The regulations limit the maximum indoor temperature a building can reach during five consecutive hot summer days. ‘Carbon’ measurements are the climate-change impact of the construction itself, including the building materials and the construction process. This is known as the construction carbon impact, which will reduce significantly over the years, by 2025, 2028 and 2031.

Order on certificates of taking into account energy and environmental performance requirements and carrying out a feasibility study on the various energy supply solutions for building construction in metropolitan France (9 December 2021)

Passed/Approved

<p>This is the Order of 9 December 2021 on certificates of taking into account energy and environmental performance requirements and carrying out a feasibility study on the various energy supply solutions for building construction in metropolitan France and amending the decree of 11 October 2011 on certificates of taking into account thermal regulations and carrying out a feasibility study on energy supplies for new buildings or new parts of buildings.The study and certificates consider the impact of climate change assoicated with building components including the construction site and requires hte client to undertake to comply with justifying the impact on climate change, and the climate change impacts arising from primary energy consumption and building components. The summer discomfort level is also measured.</p>

An aim to achieve a quantifiable outcome within a given time-frame, set by an institution such as a national government.

Policy instruments are techniques or tools used by governing authorities to promote certain policies in order to achieve predetermined goals. Put simply, instruments are how a government tries to achieve its goals, with this taxonomy being focused on national policy instruments.

Risk is the potential for adverse consequences resulting from the dynamic interplay between (climate-related) hazards, exposure, and vulnerability of affected human or ecological systems.

A set of principles, processes, and practices that build economic and political power to shift from an extractive economy to a regenerative economy.

Justice is the ethical and political framework that addresses fairness, including issues of responsibility, rights, and structural inequity.

Renewable energy means all forms of energy produced from renewable sources in a sustainable manner.

Fossil fuel is a generic term for non-renewable energy sources such as coal, fossil gas, and oil (including crude oil, and petroleum products), that can be used for electricity and heat generation. Fossil fuels are hydrocarbons formed from pressurised and heated organic material buried over millions of years.

Molecules in the atmosphere that play a key role in the greenhouse effect by trapping heat radiating from Earth’s surface.

Area of the economy in which actors engage in identical or related activities.

In human systems, the process of adjustment to actual or expected climate change and its effects, in order to moderate harm, increase resilience or exploit beneficial opportunities. In natural systems, the process of adjustment to actual climate change and its effects; human intervention may facilitate adjustment to expected climate change and its effects.
