ENDENA

The ENDENA Group is a recognized leader in sustainable real estate engineering and project management. It brings together three complementary companies: Atixis (specialized in engineering and management of all types of projects), Terao (a pioneer in sustainable real estate), and Blookod (expert in the design of applications and digital platforms).

ENDENA supports its clients in France and abroad in designing, renovating, and building sustainable real estate projects, embedding rigorous standards for energy efficiency, carbon footprint reduction, and environmental resilience. Terao’s expertise, in particular, helps optimize energy consumption and manage buildings’ low-carbon trajectory throughout their entire life cycle.

The group thus acts as an accelerator of the energy transition in the real estate sector, which alone accounts for nearly 40% of global CO₂ emissions. Thanks to its cross-disciplinary skills in engineering, eco-design, and digital tools, ENDENA actively contributes to the transformation of the built environment towards more efficient and circular models.
