HyperBuilding is a building automation application that runs on Google's App Engine platform. It allows facility managers to monitor and control building equipment like intercoms, cameras, and controllers through a web-based facility console. The application represents equipment on floor plans and shows statuses. It also allows reconfiguring devices. HyperBuilding uses open standards like Ethernet, the internet, and WebRTC for a flexible solution that can scale to buildings of various sizes and complexities. A prototype is available for demonstrations.
