About Myrium

Myrium is a leading independent operator dedicated to the sustainable performance of buildings. Through its 27 specialized companies, primarily in the Paris region, Myrium mobilizes all skills and masters all technical components (fluids and energy, including heating, air conditioning, electricity, plumbing, etc.; building envelope; architectural fittings; integrated trades; urban greening) that contribute to the performance, sustainability, and efficiency of collective buildings after their construction. Myrium thus manages the entire life cycle of existing buildings (troubleshooting, maintenance, works, performance management, etc.) to ensure their longevity, adaptation, upkeep, minimize their footprint, and enable yesterday's built heritage to meet tomorrow's needs. Its 14,200 experts and field technicians work both on a punctual and targeted basis and through long-term commitments on global operations. Myrium operates on buildings of all sizes for both public and private sectors: co-ownerships, office buildings, hotels, social housing, commercial spaces, public facilities (education, health, culture), industrial sites, data centers, etc. Originally a family business, Myrium is now mainly controlled by its teams through a successful long-term transfer project, based on employee shareholding and ensuring its independence.
