Symbiosis programme

Transformation of a disused industrial site into a sustainable tertiary zone

The Symbiosis project is a prime example of eco-sustainable urban redevelopment in Milan. It has transformed a former industrial area into a benchmark business centre, with a high level of environmental performance in terms of energy, water management and the use of bio-sourced materials.

The developers, Beni Stabili and Covivio, chose Artelia Italia to provide the engineering and project management services.


Symbiosis is part of Sharing Cities, a programme that has adopted an innovative approach to meet some of the contemporary environmental challenges, such as reducing CO₂ emissions and improving air quality. Designed by Antonio Citterio Patricia Viel, the project offers a total floor area of 24,000 m2 and meets various criteria for sustainability, smart and flexible workspaces. Contributing to the urban regeneration of the southern area of Porta Romana, it includes a tree-lined pedestrian square open to the public, gardens and ponds that mitigate urban heat and make the district healthier and more sustainable.

The solutions implemented by Artelia Italia have achieved very significant results. The energy supply is based on renewable sources (photovoltaic and rapeseed oil cogeneration). Work on energy efficiency has reduced energy consumption by 35%. Similarly, thanks to careful water management and the recovery of rainwater to supply the toilets, savings of 73% have been made on this essential resource. Our teams have given priority to the use of EPD (Environmental Product Declaration) materials and materials with recycled content and regional origin (FSC), which represent 34% of the total cost of the materials used. They also made systematic use of recovery channels, with only 1% of materials sent to landfill.

Artelia Italia’s involvement covered all civil engineering, acoustics, BIM management, facilities engineering and environmental engineering requirements. Our teams also provided overall coordination of the specialist disciplines (facades, fire, structural design, etc.) and management of the works. The building obtained LEED Core&shell Platinum certification (score of 90/110). Applications for WELL certification (Bronze level expected) and WELL Health and Safety are in progress.
