Projects

An Open Building Approach

C4SB convenes technical and market outreach interest groups and working groups who share a common vision of driving open digital transformation of real estate to unlock higher value in our buildings and built environment.  This open digital transformation supports data-informed decision making across the lifecycle of buildings, enables plug & play composable solutions, accelerates the adoption of AI, opens up vendor choice for owners, and widens the talent pool and career opportunities for real estate, facilities and related fields.

As part of the Linux Foundation, all of C4SB’s efforts are committed to collecting, developing and sharing open standards and open source resources through an open, community-driven consensus process.  Interest Groups discuss topics of interest.  Working Groups produce outputs such as open standards docs or open source code.  Interest and Working Groups are self-governing, and may explore different solutions to the same issue.  At the same time, Interest and Working Groups are encouraged to find alignment with other groups, in order to minimize confusion and maximize widespread adoption.  Ideas for new Interest or Working Groups are encouraged to reach out to info@c4sb.org.
