What is an IoT connected building specialist?

An IoT connected building specialist designs, deploys, and maintains networks of internet-connected sensors, devices, and software platforms within commercial buildings. They integrate environmental sensors, occupancy detectors, lighting controls, and HVAC systems into cloud platforms (AWS IoT, Azure IoT Hub) to enable real-time monitoring, occupancy analytics, and energy optimization.

How do IoT systems integrate with BAS?

IoT systems integrate with BAS through protocol translation gateways and APIs. IoT sensors communicate via lightweight protocols like MQTT, Zigbee, Z-Wave, or LoRaWAN, while BAS uses BACnet, Modbus, or LonWorks. Edge gateways translate between these protocols, feeding data into cloud platforms for analytics, and sending control commands back to BAS controllers for automated optimization.

What protocols do smart buildings use?

Smart buildings use a layered set of protocols. BACnet and Modbus are the dominant building automation protocols. MQTT is the standard for IoT sensor data transmission. Zigbee and Z-Wave are used for wireless sensor mesh networks. LoRaWAN enables long-range low-power sensors. Thread and Matter are emerging standards for interoperability. REST APIs and FIWARE connect to cloud analytics platforms.
