OpenAIS Report Summary

Project ID: 644332
Funded under: H2020-EU.

Periodic Reporting for period 1 - OpenAIS (Open Architectures for Intelligent Solid State Lighting Systems)

Reporting period: 2015-01-01 to 2015-12-31

Summary of the context and overall objectives of the project

The lighting industry is currently going through a radical transformation, driven by both the rapid progress of Solid State Lighting (SSL) and the changing societal needs like sustainability, improved energy efficiency and CO2 reduction. At the same time, Internet technology is developing fast and is approaching the point where it becomes economically feasible to connect each luminaire to the Internet. Because SSL-based light sources can be unlimitedly controlled (switching and dimming) and because LED drivers operate at similar voltages as IT devices, this is an excellent match. OpenAIS aims at developing the dominant design for Internet connected lighting systems with open interfaces of all electronic components. Connecting all light points in a building to the Internet will enable a large variety of new services related to comfort and well-being for the people in the building, more efficient use of the building and energy saving. As luminaires are everywhere in the building where people are, the luminaires provide an excellent infrastructure for a large variety of devices. Apart from the occupancy sensors that are already commonly integrated in luminaires, these devices may include other sensors, HVAC controllers, WiFi access points, security cameras and fire detectors. If these devices can be connected via open interfaces, many new value propositions become possible. The transition to IP will enable the transition from command oriented lighting control to service oriented lighting control. It is the objective of OpenAIS to grant the European industry a leap ahead in this new value space over non-European companies.
The project is driven by a strong consortium of leading lighting companies in Europe (Zumtobel, Tridonic and Philips) and major players in IoT technology (ARM, NXP and Imtech). Consortium partner Johnson Controls brings in expertise on efficient building management and knowledge on the needs of the users. In addition TU/e and TNO-ESI are in the consortium as prominent academic institutes. During the project, the Consortium will seek close cooperation with the IoT community. The project has an advisory board from selected industrial areas consisting of OSRAM (lighting), IBM (IoT) and E.ON (smart grid).
The OpenAIS project is partially funded by the European Union under the H2020 program.

The objectives of OpenAIS are:
• To prepare the EU lighting industry to successfully supply products for 2020’s offices, and maintain its leading position when lighting in buildings become Internet of Things connected
• To define an optimized and well thought-through open system architecture, based on IP to the luminaires, and have it accepted by the European lighting industry
• To standardize this system architecture, either during the project, or after the project
• To put the European lighting industry within a renewed value space of components, services and applications in office lighting based on this architecture and exploiting the Internet of Things
• Contribute to Europe’s energy reduction goals by combining the full power of IoT technology, LED technology and Smart Grid into a dominant lighting technology.

OpenAIS integrates concerns of all stakeholders and strengthens their positions:
• End users experience a high quality, adaptive and anticipatory lighting system. They have full control through simple interactions, including the use of their smartphones, and experience that the system improves its behaviour over time. In addition, comfort will be increased in buildings
• Building managers have information and tools to manage their building. Automatic and robust energy management and optimization of room occupancy increases efficiency of use of the building. Commissioning information is easy and fast and seamlessly included into the upcoming world of “Building Information Model” (BIM). BIM systems will be prevalent before 2020 and aim to reduce construction costs by eliminating repeated tasks over the full lifecycle of design, construction and facility management. Buildings are more and more used in a flexible way; the ability to adapt lighting easily to new use of a building is a great advantage. Personalisation and optimal comfort is becoming a discriminating success factor for the on the office rental market. In addition, regulations will require CO2 neutrality for buildings.
• Installers and commissioners experience that the plug ‘n play commissioning is straightforward and robust; a basic high-quality functionality is available out of the box.
• The building owner has a highly efficient building which can easily be (re-)used for multiple purposes. The system is extensible and capable to evolve with new technological developments.
• Manufacturers of electronic components can reduce and focus their investments because of the open system with open standardised interfaces; they integrate their components based on standard specifications.
• A special category is formed by application developers that use the open interfaces to develop new applications (“apps”) that can be downloaded and installed by users, building managers or other stakeholders.

Although the application focus of OpenAIS is on office buildings and other professional buildings, most to-be-developed concepts will transfer to other indoor lighting environments. As the lighting system in a building is a subsystem of the building management system, this project will also address the interfaces of the lighting subsystem to its environment including the advancing European Smart Grid developments.

Project Plan
The project is organized along seven work packages, of which five are visualized in Figure 1. Work Package 1 identifies the needs of all stakeholders in de value chain and translates these needs in scenarios and use cases. The requirements will be derived from these use cases. Work Package 2 defines the architecture, as much as possible based on existing standards. Work Package 3 designs and realises the components for integration tests and a pilot installation. Work Package 4 tests and integrates the components and Work Package 5 is validation in a real office setting. Within Work Package 5 an OpenAIS prototype system will be installed in an office building and will be used for validation of the use cases. Work Package 6 (Innovation Management) and Work Package 7 (Project Management).

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

"Work Package 1 Scenarios and Requirements:
In the reporting period the end user requirements for office environments in 2020 and beyond were determined. A methodology for stakeholder interviews was developed and over 700 statements were collected both through consortium partner consultation and structured interviews with 26 industry experts (D1.1) across the value chain. The consolidated scenarios that were created from the information obtained in the interviews were analyzed, distilled and grouped into three Main Scenarios that will be the cornerstone motivations behind the design work and value proposition:
1. Easy Life: about easy specification, buying, installation and commissioning, easy use and user centric modifications, And about the inclusion of lighting in the Building Information Model (BIM).
2. Increase Building Value: Enhance comfort and wellbeing in the building, hence increasing the value of the building for human resources and making it more attractive for lease or rental.
3. Building Wide Ecosystem: BMS integration and sustainability, e.g. energy saving, cross-compatibility to IT. Other building systems and software will also share data and sensors and more simply interoperate.
The User Requirements (D1.2) were derived from the collected user scenarios.

A new Vision Statement was created in a socio-technical ideation process developed by Johnson Controls (D1.3): “Create an open ecosystem to enable a wider community to deliver the smartness of light. Allow easy adaptability to cater for the diversity of people and demands.”

The Solution Specification document (D1.4) has been created on the basis of the User Requirements together with the System Requirements. With the establishment of the M33 Pilot Taskforce in WP5, a vision for the pilot installation has been considered, including Sales, Project, Support and End Use phases.

An analysis of the current lighting value chain, impact analysis of OpenAIS on this value chain on a short term (2020), and on a long term (beyond 2020) was made (D1.5) based on 4 layers: user, organization, ecosystem and society.

Work Package 2 System Architecture:
Research has been conducted and specialist knowledge available throughout the partner companies has been used to analyze the various possibly relevant IoT communication technologies and solutions (D2.1).

Candidate IoT architectures have been analyzed but these did not completely meet with the needs of the lighting industry. Essential gaps were identified in the selected, for-the -date most appropriate IoT architecture and architecture solutions were provided to resolve these gaps.

The architecture challenges from the requirements of the lighting industry, users and stakeholders are to ensure the real time operation of large quantities of light points in a secure and reliable way that also works with lost internet connections. It was necessary to introduce IPv6 node-to-node communication including secured multicast on top of the existing IoT frameworks. The existing IoT Object models need to be enhanced to cover the needs of customers for high quality lighting

This resulting final Reference Architecture (D2.3) specifies an open service oriented (communication) architecture for IP-based lighting that allows system designers in the professional lighting domain the freedom to design the systems they want to offer, while simultaneously ensuring interoperability between the components from different vendors by specifying minimum application and infrastructure layer requirements.

The related control architecture ("OpenAIS Object Model") that shows the API structure and is essential for interoperable systems, is still in progress and will be delivered in M24 according to plan.

Implementation & verification guidelines for the architecture have been described (D2.2) explaining and justifying the decision making process how the OpenAIS architecture deals with the functional and non-functional requirements for different stakeholders in the lighting value chain.

Work Package 3 Design and Realisation:
Design and realization of building blocks. In the reporting period, a common embedded software development environment for IoT (i.e. ARM mBed) was selected that is used by all developing partners, and a multi-site software scrum team organisation was setup using a shared software repository. The specifications for the MS5 milestone demonstration have been defined and a system design was instantiated from the WP2 Reference Architecture using state-of-the-art hardware/software building blocks from different partners. A preliminary demonstration has been realised showing interoperable luminaires from industry partners Philips and Zumtobel. No deliverables were due in the reporting period but WP3 is well underway to pass milestone MS5 (First iteration phase ready and accepted) in M16 according to plan.

Work Package 4 Integration of Components:
In the reporting period the integration approach was formulated by definition of the incremental integration process, addressing the challenges of integration and identifying architectural as well as component and system requirements (D4.1). It had a close relation with the architecting, development and validation activities.

A FMEA and Hazard analysis was conducted on an example system designed out of the OpenAIS Reference Architecture of Work Package 2 (D4.2). A Risk analysis was performed (D4.3) and the required test-ups were defined using an automated test framework methodology for continuous integration and testing (D4.4).

The Work Package 4 team is prepared for the integration of the lighting components and software solutions into a managed system will be realized to fulfil the OpenAIS requirements set in Work Package 1.

Work Package 5 Demonstration and Validation:
Although no deliverables were planned for WP5 during the reporting period, the work plan included starting the development of the pilot specification. Because of the central role of the pilot demonstration for the entire OpenAIS project, and the need to bridge activities towards the pilot installation of WP5, the M33 pilot Taskforce (M33TF) has been put together. During the current reporting period, M33TF has focused on identifying the key value proposition for each of the pilot phases; drafting a list of items needed for the pilot along with a lead partner proposal; writing user experience storyboards; managing the pipeline of potential customer sites.

Work Package 6 Innovation Management:

A public website was launched ( 6 Public deliverables have been published there, including the key D2.3 Reference Architecture specification and a related Q&A.

3 Conference presentations have been done on leading lighting conferences (i.e. SmartLighting 2015 and Led Professional Symposium 2015). 8 conference presentations and 6 articles have been planned so far. A data management plan was established (non-mandatory).

A liaison is being established with the Fairhair Alliance for adoption of the OpenAIS Reference Architecture with the objective to create a common IT architecture solution for lighting and building automation. (Fairhair is a global Alliance of leading companies, from the Lighting, Building Automation and IT industry, that aims to facilitate the ‘Internet of Things’ for buildings).

A draft for a Security Solution for Low-Latency Group Communication has been submitted to IETF.

Work Package 7 Project Management:

Project management guidelines have been established and published on the project internal SharePoint (as the central project management information system), including quality assurance, governance, publications, meetings, calendar, information and communication etc.

3 Plenary Technical Workshops have been organized on overall project level, including a kick-off meeting. Monthly Project Management Board meetings have been organized. An Advisory Board was established and a first meeting was held with Osram, IBM and E-on as key stakeholders.

All deliverables and milestones due for the reporting period have been achieved. There are no delays foreseen.

1.1 Expected final results and their potential impact and use (including the socio-economic impact and the wider societal implications of the action so far)
Expected final results are a communication and control architecture for IP-based lighting and the object model defining the API’s that together are the base for future standardization enabling interoperable systems..

IP connectivity will be an enabler for adopting developments and innovations from the worldwide IT community. It is expected that this will catalyse the development of a lighting and building management services offer that will serve the needs of the stakeholders throughout the value chain.

In the economic perspective, the open interface standard of OpenAIS strengthens European leadership in the market and catalyses market acceptance of connected building systems. Introducing connected lighting will increase building value and the open standard will be an enabler for competition and third party application development.

From the service perspective, data (analytics) are expected to play an important role in de-siloing the separate building systems. Sharing this data with stakeholders outside the building can make the lighting system even more valuable, but it is important to note that the applications from third party developers make the collected data valuable. Market research studies predict that IoT based intelligent energy management systems can reduce energy use in Offices by 20%, producing a potential economic impact from $11 billion to $20 billion per year in 2025.

Finally the market take up of human-centric lighting in the future can be accelerated. OpenAIS can add value by providing comfort, productivity and increasing wellbeing of many building occupants. Market research studies estimate that typical process and productivity improvements for workers enabled by IoT can yield gains of 10-30%, with a potential impact of $30 billion to $80 billion per year in 2025."

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)

While the development of IoT and the transition to SSL based lighting are at full speed, there are significant challenges to be addressed by OpenAIS. Rather than looking for just a lighting solution, OpenAIS will deliver building blocks to create solutions. OpenAIS will use state-of-the-art protocols for its architecture, such as like OPC (SOAP) for data exchange or oBIX (RESTful) CoAP (Constrained Application Protocol).
