Following the trends of the creation of the “The Internet of Things” (IoT) and the rapid penetration of SSL based lighting, it isvery advantageous to connect the luminaires in buildings to the Internet.OpenAIS aims at setting the leading standard for inclusion of lighting for professional applications in to IoT, with a focus onoffice lighting. This will enable a transition from the currently existing closed and command oriented lighting control systemsto an open and service oriented system architecture. Openness and service orientation will create an eco-system ofsuppliers of interoperable components and a market for apps that exploit the lighting system to add value beyond the lightingfunction. Added value can e.g. be related to more efficient use of the building, reduction of carbon footprint and increasedcomfort and wellbeing. In addition, IoT will facilitate smooth and effective interaction of the lighting system with otherfunctions in a building such as e.g. HVAC, security and access control. Extensibility and security of the system architectureare important aspects and will be guaranteed.The OpenAIS project will define the requirements and use cases for offices in 2020, define the best open systemarchitecture, identify existing ICT components to be used and develop additional components. The system will be validatedby a pilot installation in a real office setting. After the OpenAIS project, the Consortium will pursue standardization of thesystem architecture, aiming at the creation of the leading standard for Internet connected lighting.The project brings together a strong collaboration of the leading lighting companies Zumtobel, Tridonic, and Philips and themajor players in IoT technology ARM, NXP and Imtech. Consortium partner Johnson Controls represents the end user andacademic knowledge on ICT and system architecture is present through TU/e and TNO-ESI. During the project, theConsortium will seek close cooperation with the IoT community.
