How to choose the right BMS software

Do you need a BMS control platform or a connected operations layer on top of one?

Traditional BMS platforms like Siemens Desigo CC, Schneider EcoStruxure, and Johnson Controls Metasys are primarily designed to control and monitor building systems - HVAC, lighting, fire, access. They excel at device-level automation. If your priority is connecting that BMS data to maintenance workflows, work orders, contractor management, and performance reporting, a platform like Infraspeak sits above the BMS and turns sensor alerts into operational action. The two types of platform serve different parts of the same problem and are often deployed together.

How complex is your building systems environment?

Organisations with many different device types, legacy protocols, and multi-vendor subsystems often need an integration layer first. Tridium Niagara is the most widely deployed protocol-agnostic framework for connecting disparate systems. Siemens Desigo CC, Schneider EcoStruxure, and Carrier i-Vu all offer strong open-protocol support at the BMS layer. For teams that have already connected their systems and need to act on the data, Infraspeak, Facilio, and Honeywell Forge provide the analytics and maintenance execution layer.

What is your priority: energy and sustainability or maintenance and operations?

If your primary driver is reducing energy costs and demonstrating ESG performance, Schneider EcoStruxure, Honeywell Forge, and ABB Ability are the strongest options - all three are built with energy analytics at the core. If maintenance efficiency, asset lifecycle management, and contractor coordination are the primary need, Infraspeak and Facilio are better positioned. Most large organisations eventually need both - which is why Infraspeak's BMS integration approach is valued: it connects energy and maintenance data in a single operational view.

What is your budget and implementation capacity?

Siemens, Schneider, Johnson Controls, Honeywell, and ABB are all enterprise-grade platforms requiring certified implementation partners, significant project budgets, and multi-month timelines. Carrier i-Vu and Delta Controls offer more accessible entry points for mid-market buildings. Infraspeak and Facilio offer faster deployment paths. Infraspeak provides a free demonstration and custom scoping - a practical starting point for teams evaluating the market without a fixed deployment timeline.

Do you manage multiple sites with external contractors?

Single-site teams may find that a standalone BMS with basic reporting is sufficient. Teams managing five or more sites, with a mix of in-house technicians and external service providers, need a platform with strong multi-site visibility and supplier collaboration. Infraspeak's Network module is specifically designed for this: it connects all FM stakeholders - internal, external, and building users - in one shared workspace, regardless of which BMS is installed in each building.

Ready to connect your BMS data to maintenance action?

Infraspeak reduces MTTR by up to 83% and connects live BMS sensor data directly to work orders, maintenance workflows, and contractor coordination - across all your sites. Used by 900+ organisations including Primark, Siemens, Veolia, and Mitsubishi Electric.
