GAO’s Building Asset Inventory (Lighting, HVAC Components) System

GAO’s Building Asset Inventory System provides facilities teams with a precise, automated method to identify, audit, and lifecycle-manage lighting fixtures, HVAC modules, motorized dampers, thermostatic controllers, and other MEP infrastructure. The system deploys either RFID-only or BLE-only technologies, with an optional hybrid approach when a dual-layer sensing topology offers operational advantages. Designed for high-density mechanical rooms, plenum spaces, and distributed building zones, the system ensures real-time visibility of critical building systems across multi-site portfolios. GAO, headquartered in New York City and Toronto, brings decades of R&D investment and extensive experience supporting Fortune 500 facilities, major universities, and public-sector agencies, allowing us to deliver robust solutions supported onsite or remotely.

Enhancing Facility Maintenance: Building Asset Inventory System

GAO’s Building Asset Inventory System equips lighting and HVAC components with RFID tags or BLE beacons to enable automated identification, asset telemetry capture, and zone-level traceability. Technicians use handheld RFID interrogators, fixed RFID portals, or BLE gateways to collect device identifiers, service metadata, commissioning parameters, and location context across mechanical shafts, electrical rooms, and ceiling grids. Optional hybrid deployments integrate both RFID and BLE for environments requiring proximity-based discovery plus continuous environmental telemetry.

Purposes

• Enhance preventive maintenance workflows for lighting ballasts, LED drivers, and HVAC subassemblies.
• Support commissioning, retrofits, warranty verification, and energy management programs.
• Build an authoritative digital asset registry for lifecycle costing and capital planning.
• Enable workforce efficiency for electricians, controls technicians, and facility engineers.

Issues Addressed

• Manual spreadsheet-based inventory tracking prone to omissions and transcription errors.
• Difficulty locating dispersed lighting gear, VAV controllers, and air-handling components across large floor plates.
• Uncertainty in asset status, last-service timestamp, or actual field location.
• Lack of integration between asset data, CMMS platforms, and building automation systems.
• Inefficient rollouts of retrofit projects and compliance audits.

Benefits

• Real-time granular visibility of MEP infrastructure across complex buildings.
• Automated audit trails for commissioning agents and facility managers.
• Accelerated field inspections using RF-based or BLE-based rapid scanning.
• Higher asset uptime through accurate maintenance scheduling.
• Strong QA/QC control benefiting from GAO’s stringent product validation processes.

Local Server Version

GAO offers a local-server deployment for organizations requiring on-premise data residency, enhanced cybersecurity, or air-gapped operational environments. The local server hosts device registries, RF scan logs, BLE telemetry, commissioning data, and maintenance histories behind a facility’s secure firewall. Role-based access control, SNMP logging, LDAP/Active Directory integration, and API endpoints allow seamless interoperability with CMMS, IWMS, and BAS platforms. The system can run on ruggedized industrial servers or virtualized infrastructure, ensuring high availability and minimal network latency.

Cloud Integration and Data Management

GAO integrates scalable cloud services for multi-site facilities requiring centralized asset intelligence. Encrypted data flows from RFID readers or BLE gateways into cloud repositories supporting analytics dashboards, time-series telemetry storage, automated reporting, and AI-powered condition insights. The architecture accommodates REST APIs, MQTT ingestion, and cross-region replication. Facilities teams benefit from long-term archival, remote technician access, and enterprise-level data harmonization. This cloud-enabled approach reflects GAO’s ongoing heavy investment in R&D, quality assurance, and global technical support delivered from our bases in New York City and Toronto.
