Two major initiatives highlight the company’s commitment to modernizing infrastructure while reducing environmental impact.

Milan’s Pirelli 35: A Smart, Energy-Efficient Landmark

In a landmark partnership with COIMA, Siemens has transformed the historic Pirelli 35 commercial building in Milan’s Porta Nuova district into a smart, energy-efficient property. This project showcases a successful fusion of heritage architecture with cutting-edge technology, achieving energy savings of 60 per cent and cutting 2,000 tons of CO₂ emissions annually.

The building’s integrated building management system, Desigo CC, centrally monitors all solutions, including Heating, Ventilation, and Air Conditioning (HVAC), lighting, room automation, fire safety, and electrical distribution. This system enhances operational efficiency, reliability, and longevity while supporting business continuity.

Advanced sensors simultaneously monitor seven different environmental parameters, including air quality, energy consumption, and CO₂ levels, resulting in optimized energy efficiency, 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.

Since 2015, COIMA has partnered with Siemens to implement this technology across more than 30 COIMA-owned buildings in Milan, with Pirelli 35 serving as a prime example. This transformation has earned the building LEED Platinum and WELL Gold certifications, as well as nZEB (near Zero-Energy Building) re-labelling, aligning with Europe’s 2030 net-zero goals while preserving its architectural heritage.

Stefano Cornella, Sustainability Officer at COIMA, said:  “Thanks to our partnership with Siemens and the implementation of cutting-edge technology, 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, standing as testament to a broader commitment – not just to smart infrastructure, but to sustainability, health, and the evolving standards of urban living.”

Trieste’s Digital Twin: Enhancing Grid Resilience with AcegasApsAmga

In a parallel effort, Siemens Smart Infrastructure is strengthening its long-standing partnership with AcegasApsAmga, the Italian DSO (Distribution System Operator), to develop a digital twin of Trieste’s power grid using Siemens’ Gridscale X software.

This initiative, announced on June 16, aims to advance the city’s electrification strategy, mitigating pollution levels stemming from the Port of Trieste, one of Europe’s busiest ports.

The digital twin will proactively manage congestion challenges arising from growing integration of distributed energy resources (DERs) and the substantial energy demands of port operations.

Gridscale X will support the DSO in ensuring a stable and efficient power supply for the port, which handles over 70 million tons of cargo annually, making it a critical hub with significant energy needs. The software will identify potential congestion points and calculate the energy required to address them, ensuring a stable and reliable grid while accelerating Trieste Municipality’s electrification and decarbonization programs.

This collaboration leverages Siemens’ SCADA system and evolving ADMS (Advanced Distribution Management System) functionalities to optimize grid operations.

"As the power grid increases in complexity, we need to embrace digitalization to optimize its performance and resilience,” said Sabine Erlinghagen, CEO of Siemens Grid Software. “Collaborating with the Italian DSO, AcegasApsAmga, presents a key opportunity for the utility to leverage Siemens’ digital twin technology to simulate, monitor, and manage energy flows in real time, ensuring efficient operations and supporting sustainability goals."

A Vision for the Future

Since 2015, Siemens has been a key partner in COIMA’s efforts to digitize and transform buildings into smarter, more energy-efficient assets.

Similarly, the collaboration with AcegasApsAmga, spanning more than 100 years, presents a key opportunity to leverage Siemens’ digital twin technology to simulate, monitor, and manage energy flows in real-time. Now, with Gridscale X, the collaboration is taking a major step forward to support the decarbonization of the municipality of Trieste.
