Open · Governed · Extensible

The open layer for the buildings you already run.

CMS Buildings sits alongside your BMS and the proprietary systems already running your portfolio — connecting to them, not replacing them. Your team gets a governed, familiar interface for day-to-day operations, while an AI-native layer underneath keeps adding capability as your portfolio changes. Governed and tested at every step.

The problem

Your BMS is a closed box. Your portfolio isn't standing still.

Building management systems are proprietary by design — configured once by the vendor, locked to their hardware, and slow to extend. When your portfolio adds a site, a new sensor type, or a new reporting requirement, the BMS doesn't flex with you. Every integration becomes a project, and teams paper over the gaps with spreadsheets and one-off scripts no one governs.

  • Proprietary BMS platforms that resist integration
  • Every new data source or workflow is a slow, custom project
  • No governed, portable record of who changed what and why
  • Gaps papered over with spreadsheets and scripts no one owns
Why it matters

An industry-wide problem, not a one-off.

How CMS Buildings works

Connect, operate, and extend — on one open platform.

1

Connect without replacing

CMS Buildings speaks BACnet, Modbus, OPC UA, SCADA, and MQTT out of the box, so it sits alongside your BMS and proprietary systems instead of ripping them out.

2

Operate the full lifecycle

Commissioning to decommissioning: guided intake, asset tagging, tracking, transfers, reconciliation, and work-order management — every change attributable and auditable.

3

Extend with AI

Powered by Open Industrial: Azi and any MCP-native AI can propose new dashboards, queries, and automations over your governed building data. You approve before anything goes live.

Governed by construction

The audit trail your ops and compliance teams expect.

Not a checklist bolted on after the fact. Every action is attributable and timestamped, every change captures a reason, and the audit trail is immutable and append-only.

“Your stack, your way. CMS Buildings connects to anything — and extends everything.”

CMS Buildings connects to the BMS, meters, and proprietary systems you already run, then extends and enhances them — no rip-and-replace, no lock-in. And you choose how it runs.

Fully hosted & managed

We run and operate the platform end to end, so your team can focus on operations.

Self-hosted & self-managed

Deploy inside your own environment, owned and operated entirely by your team.

Internally hosted & co-developed

We build alongside your team in your environment, then hand off as far as you want.

Bring your portfolio onto one governed layer, in months.
