Siemens Building X

Siemens Building X is an open, cloud-based smart building operational platform and digital suite developed by Siemens to digitalize, manage, and optimize commercial building operations, energy consumption, and physical facility security. Serving as the digital foundation for sustainable and smart facilities, Building X connects disparate building automation systems (BAS), HVAC equipment, energy meters, fire safety networks, and physical security sensors into a unified digital twin cloud ecosystem. Built with security-by-design principles, Building X addresses the growing cybersecurity vulnerabilities arising from converging operational technology (OT) networks with cloud platforms by incorporating hardened communication protocols, encrypted data transit, and continuous OT device health monitoring aligned with the IEC 62443 industrial security standard. The platform features an array of modular applications, including Building Operations for centralized multi-site facility monitoring, Energy Manager for AI-driven energy optimization and carbon footprint tracking, and Security Manager for integrated physical security, video surveillance, and access control management. Siemens Building X empowers building owners and facility operators to accelerate decarbonization, enhance occupant comfort, and maintain cyber-resilient smart building infrastructure.
