2020 Environmental Regulations (FRANCE)
The RE2020 (Réglementation Environnementale 2020) is the latest French building regulation on the energy and environmental performance of new buildings and replaces the previous RT2012 (Réglementation Thermique 2012). RE2020 has been in force for residential buildings since January 2022 and brings extensive changes that go far beyond the requirements of RT2012.
Aspect of energy-efficient ceiling fans as part of a climate-friendly building concept:
| RT2012 (2012) | RE2020 (from 2022) | Comment: Relevance of Ceiling Fans | |
|---|---|---|---|
| Objective | Reduction of energy consumption (focus on energy efficiency only) | Holistic environmental approach: energy efficiency + carbon footprint + comfort | Ceiling fans offer high thermal comfort with minimal energy use – in line with RE2020 goals |
| Max. Primary Energy Demand (Cep max) | 50 kWh/m²/year | Further reduced, incentives for low-carbon systems | Ceiling fans consume approx. 5–30 W – extremely efficient compared to air conditioners (1,000–2,000 W) |
| CO₂ Emissions (ICémax) | Not considered | Limitation of CO₂ emissions over full life cycle | Low power consumption + long lifespan make ceiling fans a low-emission comfort system |
| Construction Materials (Embodied Energy) | Not considered | Life cycle assessment (LCA) required | High-quality fans made of durable, recyclable materials improve the building's eco-balance |
| Summer Thermal Protection (DH) | Limited focus | Dynamic comfort indicator (°C·h) considering heat waves | Ceiling fans improve comfort through air circulation without active cooling – ideal for passive summer strategies |
| Cooling & Comfort Measures | Mostly air conditioning, no targeted promotion of passive strategies | Priority for passive strategies: shading, ventilation, thermal storage, natural airflow | Ceiling fans are part of passive cooling strategy – low energy use, instant effect |
| Promotion of Renewable Energy | Limited | Active promotion (PV, heat pump) + preference for passive systems | Ceiling fans ideally complement PV and heat pumps: low consumption, grid-friendly, quiet |
| Ban on Fossil Heating Systems | Not banned | Fossil heating systems no longer permitted in new buildings | Fans help reduce heating and cooling demand – optimal in combination with heat pumps |
| Validity | 2013–2021 | From 2022 (residential), 2023 (office, education) | The use of energy-efficient fans can help meet RE2020 requirements cost-effectively |
| Planning Perspective | Operational energy demand | 50-year life cycle analysis: energy, emissions, comfort | Ceiling fans offer easy maintenance, long lifespan, low carbon footprint over decades |
Conclusion:
RE2020 promotes an intelligent, holistic approach to new buildings. Energy-efficient ceiling fans from Aeratron fit perfectly into this concept, as they:
- increase thermal comfort in summer,
- reduce cooling requirements and therefore the power consumption of air conditioning systems,
- require virtually no maintenance,
- and are extremely durable.
They actively support architects, planners and building owners in meeting the comfort and CO₂ criteria of RE2020 - in an elegant, economical and sustainable way.
