Abstract

Digitalisation is an effective means to achieve proper building operation and support global decarbonisation goals. Yet buildings’ heterogeneity, lack of interoperability, and vendor lock-in pose challenges to deploying data-driven applications at scale. In the current state of practice, there is no clear separation between system integration and the deployment of smart building applications, resulting in inefficient and non-scalable software components. This paper proposes a reference architecture towards decoupling system integration from application deployment, enabling the development of a platform that standardises data descriptions and exchanges, fosters interoperability, and allows scalable, vendor-agnostic deployment of smart building applications. The platform uses actor-based and microservice design patterns and leverages semantic models built on open standards-based ontologies. This approach enhances scalability in developing software components that integrate and manage heterogeneous data sources and facilitates the portability of third-party applications across multiple buildings. The paper outlines the successful implementation of the platform in two buildings, detailing the deployment of analytical and control applications while offering insights into benefits, limitations and challenges.
