RE2020: what will change on January 1, 2025
Decree No. 2024-1258 of December 30, 2024 modifies the energy and environmental performance requirements for building construction in mainland France. New RE2020 thresholds will apply from January 1, 2025, in particular to strengthen the requirements relating to the two carbon indices of RE2020. From January 1, 2025, RE2020 will strengthen the requirements […]
RE2020: the ICconstruction index
Environmental performance is one of the major developments in RE2020, which introduces new indicators. To reduce carbon emissions in the building sector, RE2020 measures the impact of buildings on climate change using a new index: Icconstruction. Launched with the RE2020 environmental regulation, the Icconstruction index sees […]
What are the drivers for carbon-free construction?
One of the objectives of RE2020 is to reduce the environmental impact of new buildings, which are responsible for 25% of CO2 emissions in France. Bioclimatic design is at the heart of the challenges facing professionals in the sector. So what are the main levers for carbon-free construction? 1. Energy efficiency of buildings Thermal insulation A […]
How does RE2020 measure the environmental impact of new buildings?
The building sector is responsible for 25% of greenhouse gas emissions in France. In this context, RE2020 is strengthening its requirements around three major objectives: ensuring summer comfort, optimizing the energy performance of new buildings, and reducing their carbon impact throughout their lifetime (50 […]
RE2020: Measuring the energy performance of new buildings
The building sector accounts for 44% of annual energy consumption in France and 25% of greenhouse gas emissions. In this context, RE2020 sets out a more demanding legal framework for environmental protection. It is based on three new objectives: ensuring summer comfort, reducing […]
RE2020: the ICénergie index
The objective is twofold in terms of energy performance. RE2020 should enable the construction of buildings that consume less energy and also use less carbon-intensive energy sources. Thus, for the first time, the regulations set a maximum threshold for greenhouse gas emissions from energy consumption. The ICénergie indicator was created with the […]
RE2020: the Cep,nr index
One of the objectives of the RE2020 Environmental Regulation is to reduce the energy consumption of new buildings. To achieve this, it reinforces certain concepts that enable this consumption to be measured. Two indices have had their requirements strengthened and a new index has been introduced: the Cep,nr index. So what does it consist of? What are its levers of influence […]
RE2020: the Cep index
One of the objectives of the RE2020 Environmental Regulation is to reduce the energy consumption of new buildings. To achieve this, it reinforces certain concepts that enable this to be measured: the Bbio index (bioclimatic need coefficient) is more ambitious and the Cep index (total primary energy consumption coefficient) reinforces its requirements in terms of performance [...]
RE2020: the Bbio index
Like the 2012 thermal regulations (RT 2012), RE 2020 implements a basic principle of energy efficiency: the cheapest and least polluting energy is the energy we don't consume. With this in mind, the energy requirements indicator (Bbio) is still present, but the regulatory threshold is more ambitious. Definition […]
