Building Automation

Patrion’s Field Service Engineers deliver turnkey and remedial services for commercial, institutional, and industrial building automation, focusing on reliable HVAC control, lighting, access, fire interface, and energy-management systems. The team commissions and maintains systems from platform vendors such as Tridium Niagara (JACE/GATEWAY), Siemens Desigo and Siveillance, Honeywell WEBs and Enterprise Buildings Integrator, Johnson Controls Metasys, and Schneider Electric EcoStruxure. Engineers integrate controllers and I/O from Allen‑Bradley (ControlLogix, CompactLogix), Siemens S7 and Desigo PX, Schneider Modicon, KMC Controls and Delta Controls, plus VFDs from ABB and Danfoss for plant-level sequencing. Field work covers open protocols (BACnet/IP, BACnet MS/TP, KNX, LonWorks, Modbus RTU/TCP, OPC UA, MQTT, DALI for lighting) and wireless/battery-free field buses (EnOcean, Zigbee) to connect sensors, VAV boxes, RTUs, chillers, boilers, and submetering equipment. Patrion specializes in retrofits: migrating legacy Modbus or LonWorks networks into BACnet/IP or Niagara frameworks, replacing proprietary BAS front-ends with vendor-neutral supervisors, and implementing submetering and power-quality metering for load-shedding and demand-response programs. Regulatory and performance compliance is central: technicians implement energy strategies aligned with ISO 50001 and ASHRAE 90.1, ensure life-safety interfaces consistent with NFPA 72 and local codes, and apply EN 15232 guidance for automated building energy performance. Cybersecurity follows IEC 62443 and NIST guidance—VLAN segmentation, industrial firewalls, Cisco/Moxa hardened switches, role-based access, certificate-based TLS, and secure VPNs are standard deliverables. On-site services include FAT/SAT execution, controller and panel wiring, sensor calibration (CO2, RH, temperature, occupancy), functional testing of VAV and AHU sequences, chiller plant optimization (lead/lag, reset strategies), lighting commissioning with DALI and daylight harvesting, and access-control integration with HID/Lenel systems. Engineers use field tools like Fluke thermal cameras and multimeters, BACnet explorers (YABE, Cimetrics), KNX ETS, Modbus Poll, Wireshark, and commissioning platforms in Niagara and Desigo. Advanced offerings include fault detection and diagnostics (FDD), analytics integration (Azure/AWS IoT, EcoStruxure IT), predictive maintenance, energy-benchmarking and M&V for retrofit projects, and turnkey upgrades that minimize downtime. Patrion produces complete documentation: I/O lists, point-maps, sequences of operation, as-built diagrams, and cybersecurity hardening reports. For plant managers, control engineers, and procurement teams, Patrion delivers measurable reductions in energy consumption, improved occupant comfort, and proven compliance with industry standards and owner requirements.
