YOUR INDUSTRY
At 3ER, we recognize that each sector faces unique energy challenges—rising costs, regulatory pressure, and the urgent need to reduce emissions. That’s why we offer targeted, high-impact solutions for municipalities, the tertiary sector, healthcare institutions, industrial sites, property managers, and social housing providers. From optimizing building performance to supporting long-term decarbonization, we help every organization turn constraints into opportunities for sustainable progress. Our mission is to deliver practical, scalable solutions that align with both environmental goals and operational realities.
Tertiary Sector
France has pledged to reduce greenhouse gas emissions by 40% by 2030. The service sector accounts for 10–15% of these emissions, mainly from heating, cooling, and lighting.

​
What solutions can help you reach these goals, stay compliant, and finance improvements without increasing debt?
Communities
Since 2021, energy costs have soared for local governments, with some municipalities seeing a 50% increase, and many municipalities seeing their bills triple. With large, dispersed building portfolios, energy efficiency is now urgent.
​
How can you reduce operating costs, meet new regulations, and fund large-scale renovations effectively?
Healthcare Facilities
Hospitals, clinics, and care homes operate non-stop, with each hospital bed consuming nearly 9,500 kWh annually-. These energy intensive buildings require targeted upgrades.

​
What energy-saving projects can be prioritized - and how can they be financed at scale?​
Industrial Sector
Industry is responsible for 20% of national emissions. To accelerate decarbonization, new rules include audits, energy taxes, and carbon reduction targets. Regulatory pressure is rising- but so are opportunities for transformation.
​
What solutions can help you decarbonize while maintaining performance and limiting capital outlay?
Property Management
Property managers must navigate rising energy bills and new performance standards across aging residential buildings. The “Décret Tertiaire” and renovation mandates add urgency to act.

​
How can you reduce energy use, meet compliance goals, and secure funding without overburdening co-owners?
Social Housing Providers
With older housing stock and rising energy prices, social landlords face growing pressure to improve building performance. Regulations like the Climate and Resilience Law raise the bar for sustainability.
