2 Contents OpenAIS objectives OpenAIS architecture IoT framework: IPv6, LWM2M, CoAP, Security OGC, out-of-the-box, BMS services Object model Architecture verification at White Lady Use cases future office: Building Wide Eco system, Easy Life, Increase Building Value Light and Network Design pilot location Collected data: occupancy, energy, app usage, etc. Conclusion // LPS-2018 // // H.Stevens // Bregenz // Public // Slide 2

3 OpenAIS fact sheet Objectives Develop an open architecture for lighting with IPv6 connectivity to the end node Enabling multi-vendor interoperability Allow software application updates to extend control functionality after installation Exploit standards and HW & SW components from IoT applications & platforms Validate in a real office setting Prepare standardization 9 partners from 6 countries January 2015 June 2018 All objectives are met. // LPS-2018 // // H.Stevens // Bregenz // Public // Slide 3

4 Architecture aspects Existing IoT architectures do not fully meet the requirements from lighting industry & stakeholders: Low latency secure group communication (IPv6 multicast) Daily operation is independent of a central server Object models for high quality lighting and integration into BMS. Architecture is optimized for bandwidth (RF) with favorable scaling parameters Basic Out-of-the-Box functionality to support electrical contractors Architecture solutions provided to resolve these requirements: Open (secure) Communication (OGC) Fast and secure OGC designed for object-to-object communication Enabled for vendor diversity and fast user interaction Object data model (API) High performance embedded operational functions: speed and resilience. Reference Architecture has been published: ( // LPS-2018 // // H.Stevens // Bregenz // Public // Slide 4

5 Maturity IOT Framework selection Situation 2015: The number of claimed IoT-frameworks was large Maturity is very low, many were paperware only. Many derived from PC and CE frameworks, high resource claims Covering only a part of the chain (from cloud device) Smart M2M Lightweight M2M OpenAIS selected: LWM2M i.c.w. Lightweight-ness Situation 2018: Also OCF (iotivity) or other CoAP based frameworks may be applicable // LPS-2018 // // H.Stevens // Bregenz // Public // Slide 5

7 Main uses cases for future offices Easy Life a solution that is easy to specify, design, install, commission, operate and maintain without making compromise on ease of use.. Increase Building Value in the changing world of office space and provision owners will need to make their properties more attractive for businesses to lease or rent... trophy workplaces making visits to the office a luxury and a rewarding experience. Building Wide Ecosystem.in the future, systems in a building will be expected to share sensors and, interoperate to the benefit of the building and their stakeholders // LPS-2018 // // H.Stevens // Bregenz // Public // Slide 7

8 Advantages of IP connected Lighting Easy Life Reduced R&D effort: Reuse of common infrastructure, platforms and technologies Standard CPU s, standard OS (Linux or Arm-MBED), software download, device management, security Development staff is much more abundant when making use of standard platforms. Simplified Installation & Integration: use of standard IT tooling Reduced maintenance cost: no key development staff needed, no vendor specific technology is used IoT-based lighting systems offer through their open interfaces the ability to easy extend and modify the system, including the extraction of current configurations from the field devices. Increase Building Value Context awareness of lighting system: integration of various types of sensors Green building certifications (e.g. LEED and WELL) User access support: OpenAIS integrates with IT infrastructure to user s mobile devices Building Wide Ecosystem Share lighting control communication infrastructure with other functions to provide building services, reducing cost for applications that just need sensor information Ease of integration on data and control level: data collection function // LPS-2018 // // H.Stevens // Bregenz // Public // Slide 8

14 Conclusion OpenAIS has proven that an architecture for (professional) lighting systems can be based upon the quickly developing technologies for IoT-infrastructure. OpenAIS has addressed the topics where (professional) indoor lighting differentiates from commonly existing IoT systems and dealt with the gaps existing at the conception of the project and architecture OpenAIS also has been firmly pushing some of its findings and innovations to related standardization bodies, building on an IoT-infrastructure that will fully serve the lighting industry The project and its pilot have validated the main predicted benefits in the areas of: Increasing building value by enabling many new and flexible applications for lighting control and beyond. Enabling a building wide ecosystem by using the lighting infrastructure as a backbone and by standardizing on IP based communication with OpenAIS By increasing the ease of life for development, installation and maintenance by reducing costs and facilitating new levels of functionality // LPS-2018 // // H.Stevens // Bregenz // Public // Slide 14
