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.
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
An industry-wide problem, not a one-off.
- ~40%
- Of global energy use runs through buildings
- Dozens
- Of siloed, vendor-specific systems in a typical portfolio
- Months
- To integrate a new building system with the BMS
- Little to none
- AI-native extensibility in incumbent BMS platforms

Connect, operate, and extend — on one open platform.
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.
Operate the full lifecycle
Commissioning to decommissioning: guided intake, asset tagging, tracking, transfers, reconciliation, and work-order management — every change attributable and auditable.
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.
Everything a modern building operations team needs.
Operations
Asset intake, a guided commissioning workflow, tagging, tracking, transfers, reconciliation, and end-of-life decommissioning.
Connect
A governed integration layer over your BMS and proprietary systems — discover points and devices, control access, and extend without a rip-and-replace.
Compliance & Governance
Governance by construction, immutable audit trail, and feature-locked, access-rights-controlled dashboards for every role on your team.
AI & MCP
Azi the assistant and a governed MCP server let Claude, GPT, Copilot, or your own models operate on building data — propose, approve, act.
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.
