Green Building
Taking action today to build the real estate of tomorrow: that is the commitment we uphold through our eco-construction solutions.
Our mission? To help you design, renovate, and operate high-performance, low-carbon buildings that respect biodiversity and ensure user comfort.

Head of Environmental Project Management Division at Sinteo
The Challenges
- Climate Emergency and Low-Carbon Transition
Buildings account for a significant portion of CO₂ emissions (25% of greenhouse gas emissions in France). Reducing carbon impact, particularly through energy renovation and eco-construction, is central to environmental policies.
- Climate Emergency and Low-Carbon Transition
- Biodiversity and Resource Preservation
Real estate projects must now consider their footprint on habitats, fauna, flora, and resource management (water, materials, soil, etc.).
- Biodiversity and Resource Preservation
- Occupant Comfort and Health
Indoor air quality, acoustics, natural light, and thermal comfort: occupant well-being has become an essential criterion for a building's value and longevity.
- Occupant Comfort and Health
- Regulatory compliance and economic competitiveness
With the Tertiary Decree, RE2020, and ESG requirements for investors, compliance is now a key asset for securing and enhancing the value of real estate portfolios. - Image Enhancement and CSR Commitment
Engaging in eco-construction strengthens the reputation of a committed and responsible stakeholder, while addressing new societal expectations.
- Regulatory compliance and economic competitiveness
Our conviction: 'A sustainable building must serve life.'
We believe in the power of real estate that respects people and their environment. By working towards energy efficiency, low carbon, reuse, and biodiversity preservation, we collectively contribute to a resilient and meaningful living environment for both users and investors.

Commissioning to Achieve Actual Energy Performance
Commissioning is a process focused on anticipating quality for the benefit of operations. It is a management tool designed to achieve actual energy savings while reducing building operating costs.
When acoustic design embraces biodiversity.
In the shadow of the challenges posed by climate change, a topic that receives far less media attention than global warming could nevertheless cause quite a stir. It concerns the acoustic state of our planet—and, in particular, the living world. Silence
