Energy Renovation: A Desirable Change of Scale

Methodology

• Survey: Conducted by Harris Interactive in March 2024 across 8 European countries (Belgium, France, Germany, Italy, Poland, Portugal, Spain, and the United Kingdom).
• Participants: 13,000 individuals aged 18 to 65, drawn from nationally representative samples.

How Do Europeans Perceive Their Housing?

• Comfort: 89% of Europeans are generally satisfied with their accommodation, with comfort being the top satisfaction criterion for 1 in 2 Europeans.
• Energy Expenditure: 35% of Europeans face difficulties related to housing expenditure, and 4 out of 10 consider their energy bills excessive.

Efforts to Reduce Energy Consumption

• Monitoring: Half of Europeans monitor their energy consumption using applications or meters.
• Actions: 74% turn off lights when leaving a room, 58% close windows and shutters when it's cold or hot, but only 36% have installed low-consumption light bulbs or lowered their heating temperatures.
• Results: Only half believe these actions are sufficient to achieve significant energy savings.

Mobilization for Renovation Work

• Current Status: 46% of Europeans have already carried out energy renovation work in the last 3 years, while 28% plan to do so within the next 3 years.
• Motivations: Financial savings (33%), gain in comfort (30%), and ecological conviction (21%) are the top reasons.
• Work Types: Small, localized works dominate, with 38% of owners having done small renovations and 42% having done only minor ones. Major renovations account for 20%.

Levers to Speed Up Energy Renovation

• Awareness of Energy Waste:

  • Sensory Perception: 53% of homeowners feel a significant sense of energy waste, while 17% have no sense of it.
  • EPC Knowledge: 51% of European owners know their EPC rating, and there is a correlation between the sense of energy waste and willingness to carry out work.

  • Information: Barely over half of Europeans feel well-informed about the main phases of renovation projects.
  • Trust in Players: Banks (80%), aggregators and renovation specialists (74%), large building enterprises and manufacturers (65%), and energy suppliers (55%) are trusted, with banks seen as essential in supporting energy renovation projects from start to finish.

Conclusion

To successfully accelerate energy renovation, efforts should focus on better informing homeowners at all levels, increasing awareness of energy waste and the benefits of renovation, and working together to support European customers.
