A technical overview of Microsoft’s own use of the Azure Gateway SDK, Azure IoT Hub, Stream Analytics, SQL databases, Power BI, and Microsoft Dynamics 365 Field Services to monitor building equipment (HVAC, Power Meters, etc.) on the Redmond campus and send this data into IoT Hub where it is analyzed and presented to our facility management organization to detect failures, optimize equipment functionality, and manage work orders. In this talk we discuss Microsoft’s experience in using this data to manage our own campus equipment live in Microsoft building 19. After this overview, we detail the architecture of the gateway solution (built using the Azure Gateway SDK), including how the gateway talks to legacy building equipment using the BACnet protocol, converts this information into a JSON payload, and then sends this information to IoT Hub and the IoT suite for further processing.
