Optergy Enterprise vs Siemens Building X

Optergy Enterprise is paid, on-premises building management software hosted locally for real-time control, measurement, and reporting. It combines building automation, energy management, and tenant billing, with web access and listed Android, iOS, Windows, API, and self-hosted support. Utility and sub-meter readings are monitored continuously, and anomaly alerts can identify location, time, and cost implications. Users create trends, alarms, schedules, and calendars, with escalation for unacknowledged alarms. Reports are customizable and available as web, PDF, or CSV outputs that can be emailed automatically. BACnet and Modbus TCP-IP connectivity supports building systems, while a third-party API connects custom applications and devices. Tenant billing covers utility and after-hours energy use but does not collect payments. The base licence includes 150 devices, up to three tenants, 50 Optimum Start areas, and 50 Demand Limiting points, all expandable. Users and groups are unrestricted, with live and scrolling displays. The product page states there are no ongoing fees, but purchase pricing is available only on request.

Siemens Building X is a cloud platform for managing building operations and using building data to improve sustainability, operations, and performance. Its applications address energy and sustainability, safety and security, and operations and maintenance. Energy Manager monitors energy use and costs, compares building portfolios, and provides custom performance indicators, analytics, and reporting. Building X connects with equipment from different vendors through Siemens solutions, gateways, and standard protocols; Siemens devices are not required. Open APIs support application development and system integration, including access to application, building, and user account data. Siemens hosts the platform on AWS and carries out deployment. Siemens says the building owner owns the data and determines how it is accessed, shared, and used. The company lists ISO/IEC 27001, 27017, and 27018 certifications and a SOC 2 Type II report for Building X; Energy Manager is ISO 50001-certified. Subscriptions are yearly, with pricing available by quote. Customers must contact Siemens about cancellation policies and regional availability. Workplace Experience supports mobile and web access and kiosk-supported access.
