San Juan de Dios Hospital in Seville has reduced its operational costs by 35% after implementing Siemens’ AI-powered building management platform, Building X.
The digital system integrates energy, security, and HVAC (heating, ventilation and air conditioning) management into a single, intelligent solution.
The project, led by Siemens Smart Infrastructure, claims to have transformed the 450-year-old hospital into a fully digital, data-driven facility.
Building X serves as the central operational system, using AI-based applications to monitor and optimise energy performance, detect faults early, and improve equipment use. Siemens says the platform could enable a further 10% in cost savings over time.
The technology is part of Siemens Xcelerator, an open digital business platform that helps organisations accelerate their digital transformation. The platform is designed to digitalize, manage, and optimize building operations.
“With Siemens’ technology, we have gone beyond simple automation,” said María Jesús Pareja, managing director at San Juan de Dios Hospital.
“We now have an intelligent system that coordinates, optimizes, and anticipates the functioning of our facilities, improving care quality and the well-being of those around us.”
Buildings account for around 40% of global carbon emissions, according to Siemens, and healthcare facilities face growing pressure to reduce environmental impact while managing costs.
Siemens hopes its digital building technologies will tackle both challenges by combining efficiency, sustainability, and resilience.
At San Juan de Dios, Siemens has deployed a digital layer that includes remote fault detection and diagnostics, intrusion detection via its Siveillance Suite, and the Desigo CC building management system.
Through Building X’s Operations Manager and Energy Manager, the hospital gains real-time visibility into building performance and energy consumption, helping facility managers make faster, data-informed decisions.
“This project sets another benchmark for hospital digitalization globally,” said Delphine Clément, global head of verticals at Siemens Smart Infrastructure Buildings.
“By harnessing AI and interoperable platforms, healthcare facilities can transform operational complexity into simplicity and resilience – ultimately improving care outcomes while cutting costs.”
