Vendor-Independent Data Platform Architecture in Smart Buildings

In recent years, smart buildings have garnered attention for their ability to integrate various systems and devices within a building, allowing for centralized data platform-based control to achieve purposes such as energy management. Smart building data platforms are required to provide vendor-agnostic APIs (for device control and data acquisition) and simplify device addition and operation. In this paper, we design a platform architecture that fulfills those requirements. The differing IoT gateway functionalities for each device are dynamically deployed to the IoT gateway. The devices are abstracted into metrics, which are a type of data, and the API is called with the metric and the building structure in which the device is located. Furthermore, we propose a method to standardize metric names of the same type across the platform. The designed platform is implemented and verified.
