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.
Infrastructure
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.
Interoperability
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.
And the first IBB-enabled products are shipping and more are on the way.
Imagine "plug & play" interoperability for the systems in your buildings

Upcoming Events
Linux is coming to buildings!
Join us at RealComm/IBcon where we'll explore the exciting intersection of smarter buildings with open-standards and open-source technologies.
You'll see how the convergence of the Coalition for Smarter Buildings (C4SB) and the Linux Foundation is creating valuable opportunities for the owners and managers of smarter buildings.
Monday, June 2, 2:15 pm, Precon Accelerator:
C4SB and the Linux Foundation.

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.
