The FacilityOS platform

Nine facility systems in one product, plus a control-room video wall and an AI assistant. They share one data model, one alarm system, one change-approval flow, one audit trail and one set of users and roles.

FMCS

Facility management and control

The whole cooling and power chain at a glance, with redundancy, shift handover, utility efficiency and first-out alarm analysis.

Learn more →BMS

Building management system

Air-side equipment, setpoints with approval, schedules, holidays, optimal start, OpenADR demand response and automatic fault detection.

Learn more →EPMS

Electrical power monitoring system

IEC 61850 read-only, sequence of events to the microsecond, COMTRADE waveforms, power quality, breaker wear, relay settings, arc-flash labels and transformer life.

Learn more →EMS

Energy management system

Electricity, gas, water and steam metering by workshop and system, time-of-use cost, demand, carbon, PUE and tamper-evident report archives.

Learn more →SCADA

Supervisory control and data acquisition

Editable HMI graphics, live values and trends, bulk history export to CSV and Parquet, event replay, and northbound OPC UA and MQTT Sparkplug B.

Learn more →PLC / DCS

Process control

PID loop faceplates, ISA-88 batch records, controller redundancy, EtherNet/IP and Siemens S7, and a soft-PLC IDE with simulation.

Learn more →CMMS

Maintenance management

Asset register linked to live data, preventive maintenance by calendar, run hours or starts, signed work orders, QR/NFC inspection rounds, spares and MTBF/MTTR.

Learn more →DCIM

Data center infrastructure management

Rack elevations, A/B power-chain tracing, capacity planning, rack power budgets, thermal heat maps and per-customer power billing.

Learn more →CEMS

Continuous emissions monitoring

Hourly values to EPA 40 CFR Part 60 / Part 75, permit limits, daily calibration drift, missing-data substitution, quarterly reports and a hash-chained record.

Learn more →Video wall

Control-room displays

Drag-and-drop dashboards for control-room screens: KPIs, trends, alarms, graphics and cameras, full screen in 1080p and 4K, with rotation across boards and sites.

Learn more →AI assistant

Read-only operations assistant

Explains alarms, finds root causes, writes shift summaries and answers questions about site data, and turns statistical findings into maintenance suggestions. It never operates equipment.

What every module shares

Multi-site: each site has its own time zone, gateways, devices, alarms and audit; a site can have several gateways.
Roles: operator, engineer and manager, set per site; multi-tenant for colocation customers; Microsoft Entra ID single sign-on.
The 8-step change flow for every write to equipment, with emergency stop available to every role.
Pilot rollout in three stages: read-only → limited control → full control, each step checked and confirmed by two people.
Training by role with sign-off and a drill mode whose alarms never touch the real system.
High availability: multi-node primary/standby or active-active with automatic takeover, backup and restore, and a Prometheus metrics endpoint.
Bilingual interface, installable on phones as a PWA.

Architecture

FacilityOS Core

The platform service, written in Go: web app and API, accounts, alarms, approvals, audit, multiple sites and high availability, with a built-in NATS message bus.

Field gateway fos-edge

Written in Go and installed on a Linux industrial PC (amd64 or arm64) at the site: protocol collection, pre-checks before writes, durable on-disk buffering during outages and the soft PLC.

Database

PostgreSQL with TimescaleDB for state, audit and historical trends.

Web app

React and TypeScript, installable as a mobile PWA.
