Open protocols: avoiding vendor lock-in in building automation

The protocols your building speaks decide whether you are free to choose equipment, or tied to one supplier for its whole life.

A building automation system lasts for years and will be extended, upgraded and partly replaced many times. The protocols it uses to connect everything quietly decide whether those future changes are easy and competitive, or whether you are locked to one vendor's prices and timelines.

The open protocols that matter

  • BACnet for building automation and HVAC
  • Modbus for plant, meters and industrial devices
  • KNX for lighting, blinds and room control
  • DALI for addressable lighting control

Why openness protects you

When systems speak open protocols, you can add equipment from different manufacturers, get competitive quotes, and bring new systems onto the same platform. A closed, proprietary system can leave you dependent on one supplier for every future change.

Design for the long term

Specifying open protocols from the start, and an integration platform built to use them, keeps a building flexible for its whole life. It is one of the most valuable decisions made early and regretted if missed.
