Siemens and COIMA transform Milan heritage building into smart, energy-efficient landmark

– Siemens’ latest project with COIMA showcases successful fusion of heritage architecture with cutting-edge tech
– The “Pirelli 35” commercial building delivers energy savings of 60%, cutting 2, 000 tons of CO₂ emissions annually
– Siemens' Desigo CC building management system centrally monitors all building technologies and offers a fully integrated solution

Siemens Smart Infrastructure and COIMA, a leader in the investment, development and management of real estate assets on behalf of institutional investors, are continuing their long-term strategic partnership with one of the most iconic buildings in Milan's Porta Nuova district – “Pirelli 35”. The goal is to transform the 45, 000-square-meter, 11-storey asset into a smart and energy efficient property. The 65-year-old building is set to demonstrate exceptional environmental performance to its 40 commercial tenants by reducing energy consumption by approximately 60 percent and CO₂ emissions by 2, 000 tons on an annual basis.

Siemens' integrated building management system, Desigo CC, is one of the key technologies enabling the achievement of these targets. The solution offers a high level of cybersecurity protection and orchestrates all building operations in a single, centrally monitored system. Being able to oversee all solutions and systems – such as Heating, Ventilation, and Air Conditioning (HVAC), lighting, room automation, fire safety, as well as electrical distribution – facility managers are equipped to enhance operational efficiency, reliability and system longevity, supporting business continuity. Meanwhile, the building features advanced sensors simultaneously monitoring seven different environmental parameters, including air quality, energy consumption and CO₂ levels. This not only results in optimized energy efficiency, but also in increased occupant well-being, productivity and safety. The building’s comprehensive electrical infrastructure includes a SIMOSEC medium-voltage switchgear, 59 ALPHA low-voltage switchboards with SENTRON protection devices, and 35 control panels, ensuring optimal system control throughout the building.

“In major cities, many buildings could benefit from digitalization, transforming into smarter and more energy efficient assets. Since 2015, we have partnered with COIMA to implement Siemens’ building technology and services across more than 30 COIMA-owned buildings in Milan, ” said Susanne Seitz, CEO Buildings at Siemens Smart Infrastructure. “Pirelli 35 is a prime example of this, serving as a blueprint for sustainable urban regeneration. It showcases how buildings can be modernized with building and electrification technology to meet Europe's 2030 net zero goals while maintaining their architectural heritage.”

“Thanks to our partnership with Siemens and the implementation of cutting-edge tech, we are able to transform Pirelli 35 into a truly smart building. It’s already achieved LEED Platinum and WELL Gold certifications as well as its nZEB labelling stand as testament to a broader commitment – not just to smart infrastructure, but to sustainability, health, and the evolving standards of urban living, " Stefano Corbella, Sustainability Officer at COIMA, added.

Leadership in Energy and Environmental Design (LEED) is a green building rating system with Platinum being the highest certification, while the WELL Building Standard certification stresses a building’s advanced human health and well-being. nZEB stands for Nearly Zero-Energy Building and highlights high energy performance and low-energy needs. All three are internationally recognized.
