Introducing the IBB:
the Interoperable Building Box
Imagine "plug & play" interoperability for the systems in your buildings
Today’s buildings and building management systems face two core problems: Infrastructure and Interoperability.
Infrastructure is a challenge, especially at the edge boundary between on-prem systems and the cloud. Interoperability is a problem because most on-prem systems are not designed to work with other systems, but to run in a 'silo' for their specific needs.
The Interoperable Building Box (‘IBB’) addresses both of these problems with a vision of a plug-and-play platform that manages the necessary networking infrastructure while automatically matching the capabilities of systems with each other with minimal user intervention.
The 'Infrastructure Problem'
The IBB addresses the Infrastructure Problem by replacing the current mashups of gateways, applications, and protocols with a single extensible cloud-native software platform that resides on a physical or virtual server in the building. Your applications run in standardized containers on a Kubernetes cluster in the IBB, and they enjoy the benefits of cloud-native technologies while being inside the building.
The 'Interoperability Problem'
The IBB addresses the Interoperability Problem by replacing hard-to-manage proprietary APIs with an open-source orchestration platform. This enables vendors and integrators to spend less time on integration and maintenance and more time creating new innovations and solving customer problems with better tools.
The IBB Ecosystem: from the edge to the cloud
The IBB model can be applied up and down the stack of operational technologies in a building: from tiny IoT edge devices and gateways to cloud-based enterprise systems. Manufacturers are developing and shipping IBB-enabled products. The IBB Ecosystem report shows you what's happening now.
A detailed introduction to the IBB, including the architecture, the types of IBBs and components, and a discussion of adoption paths and implementation considerations, is available in the IBB System Overview document.

C4SB has joined the Linux Foundation!
It's official: the Coalition for Smarter Buildings, the home of the IBB, has joined the Linux Foundation as the 'C4SB Foundation.'
This is an endorsement of C4SB's mission and work to date, and a huge opportunity to benefit from Linux Foundation's resources and membership to extend C4SB's reach.

About the IBB Project
The IBB Project was created in 2023 by the Coalition for Smarter Buildings ("C4SB") with the support of the Monday Live! think tank group.
The mission of the IBB Project is to create an open-source and cloud-native software stack for an edge device that can provide a consistent, open, and secure way for systems found in buildings to communicate with each other and with cloud resources.
The IBB enables authorized users to install containerized applications into their IBB and orchestrate automatic capability matching to create a plug-and-play application environment.
