Poster Abstract: XBOS: An Extensible Building Operating System

We present XBOS, an eXtensible Building Operating System for integrated management of previously isolated building subsystems. The key contribution of XBOS is the Building Profile, a canonical, executable description of a building and its subsystems that changes with a building and evolves control processes and applications accordingly. The design and implementation of XBOS addresses the six dimensions of an effective BAS -- hardware presentation layer, canonical metadata, control process management, building evolution management, security, scalable UX and API.
