SWIMing Report Summary

Project ID: 637162
Funded under: H2020-EU.

Periodic Reporting for period 1 - SWIMing (Semantic Web for Information Management in Energy Efficient Buildings)

Reporting period: 2015-02-01 to 2016-01-31

Summary of the context and overall objectives of the project

The ‘SWIMing’ project will bring together existing EeB projects under clusters categorised by which stages of the BLC the project is applied and energy savings are achieved and the particular domains within those stages to facilitate knowledge sharing and increase the impact of project results. It will support making the project processes and the data produced by these processes publishable as linked data on the web and through this structured format (BIM-LOD), make data more accessible and less fragmented across the BLC. This data sharing will address the requirements that span application domains and BLC stages related to energy efficient practices in buildings, thus easing the exploitation of project results beyond the specific application evaluated in individual projects. The approach will also align projects with the wider knowledgedriven economy made possible by the open technology and broadening skill base growing around open web data standards and the resulting technologies will help reduce energy use and Greenhouse Gas (GHG) emissions worldwide, by making Europe a competitive leader in the green building industries.

Through this clustering activity, members of the EeB community will be able to publish their outcomes in a manner which facilitates their exploitation and dissemination amongst the wider BLC Energy Management (BCLEM) communities. SWIMing is unique amongst existing EeB projects as it will specifically focus on addressing the issue of making building related knowledge and data more accessible and less fragmented across between projects and across the BLC. The project will work in parallel with existing efforts, for example E2B1, in promoting the use of technologies which support the process of dissemination of project results.

Objectives: The project’s mission is the creation of a cluster around the use of Linked Open Data for Building Information Modelling that supports Building Life Cycle Energy Management (BLCEM) tasks, overcoming the barriers set by multiple stakeholders, different scopes and conflicting needs. By achieving this goal, SWIMing will impact on the ease and efficiency with which existing EeB Projects can exploit their processes based on BLCEM services.
Targets: This project aims to exploit and build upon BIM Linked Data for BLCEM by establishing a strategy from today’s industry practice and technological capabilities to the vision of BIM L(O)D. SWIMing addresses three key objectives:
1. Cluster existing Seventh Framework Programme and H2020 projects which have been funded under the area of Energy Efficient Buildings. A full review of the type of domains, application areas and data modelling these projects address will be conducted, with the outcome of aligning each project to its appropriate area within the BLC and in particular how BIM and LD technologies can support the exploitation of these results.
2. Workshops addressing each stage within the Building Life Cycle Energy Management (BLCEM) will be organized, inviting project partners to share and highlight their project outcomes. Through workshops and EU-wide discussion, consensus will be reached on short and long-term goals of each area of the cluster to identify how BIM and LD technologies can support wider uptake of project results.
3. The existing project models will undergo a process of alignment with LD technologies, thus making them publishable through a dedicated information space following established EU Data Management and W3C guidelines . The models will be expressed with additional meta-properties, including provenance, security and intellectual property rights, to support filtering, querying and aggregation of data across multiple stakeholder data stores.
Steps: The project will be cyclic in nature. A strong involvement of the community (industry, technology providers, researchers, society, etc.) will be needed to inform each of the iterations with new business use cases and assessments. The community will be approached by means of strategic studies, as well as by events that will support networking and the establishment of synergies. From the analysis of the business use cases, a set of requirements and common BLCEM data requirements will be identified. A set of guidelines and best practices will be created/updated in each iteration and will be put at the disposal of the community members to allow them to contribute with further resources and/or use cases. Our purpose is to guide the transformation of such resources in a way that allows for their reuse and interoperation on the Web, by following Linked Data recommendations and Semantic Web standards.
Benefits: SWIMing outcomes will be:
• An open and sustainable global community of stakeholders in industry, research and standards, interested in the use of free, interlinked, and semantically interoperable BIM resources for BLCEM.
• A set of guidelines and best practices for integrating BIM resources into the LD cloud, as well as generating and exploiting LD-based BIM resources for BLCEM.

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

During the first 12 months of the project, we performed all tasks as planned in the description of work. These tasks can be grouped as: industry use case activities that gather those activities performed in WP1, technical activities that includes those activities performed in WP2, and cluster building activities performed in WP3. Next, we highlight them:

Industry Use Cases activities (WP1)
In the period we have 32 members signed up to the LBD community group, with active participation from those members towards the development of use cases. We have also through our communication with the appropriate project partners and analysis of project deliverables, extracted 46 high level use cases for 33 EeB projects. Further to this, a classification of these use cases into several core areas of relevance to EeB projects, has been accomplished. These results can be now found on the Linked Building Data (LBD) community group wiki and also in deliverables D1.1 [2] and D2.2 [3].
Guidelines, and best practices activities (WP2)

WP2 has built upon the use case development in WP1 by identifying a methodology for capturing use cases, identifying their data requirements, aligning these with existing ontologies, linking these to new (and potentially developing new ontologies) or existing ontologies, and publishing this data on the web. Further to this, we have begun the challenging process of extracting data requirements from project use cases and also use cases provided by members of the LBD community. Using this methodology, and a tool developed by AEC3 called the Requirements Capture (ReqCap) tool, we explored 11 use cases in greater detail, and reported on our findings on the Linked Building Data (LBD) community group wiki [1] and in deliverables D2.2 [3].
During the course of SWIMing the Linked Data Working Group (LDWG) has also been created in buildingSMART to oversee the standardization of ifcOWL . SWIMing was present at the LDAC technical session where the application of W3C guidelines on the publishing data on the web (presented in part in D2.1 [4]) was discussed as a basis to inform the development of the ifcOWL standard. SWIMing has also been actively involved in regular telecons (through Matthias Weise) and in providing financial support to the co-chair and a major driving force behind ifcOWL, Pieter Pauwels.
Cluster building activities (WP3)

Awareness for SWIMing topics has been raised in a broad range of academic fora, including the LBD community, BuildingSmart LD workshop (35 participants), the LDAC workshop (29 participants), Ready4SmartCities (R4SC) Summer School (27 students), the Sustainable Places workshop (19 participants), two VoCamp workshops (66 participants in total), the EC hosted EeB Impact Workshop, and an expert’s workshop hosted by our sister CSA, EEBERs. The awareness for SWIMing topics has been raised in industry fora like the buildingSMART conference 2015, IERC conference, Cork, the SEAI Energy Info day, Dublin, the National Sustainability Summit, Dublin, the IBSPA International Conference, Hyderbad and the IBSPA-Ireland Research Symposium, UCD.
Here we briefly describe in more detail the 3 co-hosted workshops SWIMing undertook and also 2 further workshops in which SWIMing participated by providing tutorials and chairing technical sessions using the ReqCap tool. The 3 co-hosted workshops in chronological order:
• SWIMing co-hosted a workshop with the LDAC group at the BuildingSMART conference in Watford/UK on 24th March. 35 participants attended the event where active use case/requirements prioritization were discussed.
• The LDAC event in Eindhoven/The Netherlands, which was hosted by the LDAC group, had 29 participants. A break-away session organised by SWIMing had 8 participants explore use cases around energy simulation. At this session the use case and data domain categorization were evaluated by the BIM experts attending. A further 15 participants attended a hands-on-session, led by SWIMing, in which three technical sessions occurred.
• The Sustainable Places workshop held in Savona, Italy and which was co-hosted with EEBERs. It had 19 participants and was used for disseminating information about CSAs SWIMing, EEBERs, and R4SC as well as a number of selected projects.
The 2 VoCamp workshops in which SWIMing participated in chronological order:
• The R4SC VoCamp in Genoa, Italy, on supporting open linked data and interoperability for efficient energy systems in smart cities was held in. The event had 16 participants and looked closely at alignments between IFC and SAREF ontologies, as well as some cursory exploration of CityGML. SWIMing engaged with the participants defining alignments.
• The SEAS VoCamp in Paris, France had 50 participants over three days. A diverse set of topics were discussed, and SWIMing had the opportunity to have multiple (3 one and a half hour sessions) with members of the SEAS project using the ReqCap tool to capture use cases. From this, two were chosen to add to D2.2 around energy efficient communication with building devices.
Upcoming activities beyond M12 will cover at least 3 workshops and 15 conferences (see Deliverable 3.2 Cluster building and dissemination plan for more details).

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)

SWIMing establishes a long-term vision towards a broad ecosystem in which a community of interested users, industry, and academia will be supported for the development of Building Information Modelling Linked Open Data for Building Life Cycle Energy Management. By enabling an ecosystem for BIM-LD-based BLCEM, the project is expected to bring these direct impacts:
• Raise awareness of experts in academia and industry towards the benefits of using free, open and interoperable resources and Linked Open Data for BLCEM. This is being achieved through interaction with EU projects, face-to-face meetings and discussions regarding data requirements to meet specific use cases.
• Establish a network of interested peers from industry and academia that are stakeholders in data provision and technology development. This network will aid adoption of Semantic Web standards to increase data interoperability between the various stakeholders’ information systems and applications, and allow for a sustainable maintenance of free, open and interoperable data sets and services that are relevant for BLCEM.
• Application of an existing standard methodology (IDM), adapted to meet the specific needs of BLCEM to the development of use cases. This methodology includes the allocation of stakeholders, processes, and data requirements as a pre-process for the publication of Linked Open Data.
• A central repository (the ReqCap tool) for use cases and data requirements, for quick and easy access to data on other projects use cases and data requirements.
SWIMing will validate its year one outcomes by discussing them with the community at large through the W3C group (LBD), the LDAC Community and BuildingSmart Linked Data Work Group (LDWG), as well as the organization of three further clustering workshops. Outcomes concern: (i) conversion of BIM resources and its metadata, (ii) best practices for BIM Linked Data, and (iii) the guidelines for BIM Linked Data for BLCEM.
In addition, SWIMing will reach out to new groups that have not been targeted in year one. To be informed and to contribute BIM-LD data and the SWIMing project, we established:
• Project website
• W3C Community Group on “Linked Building Data”
• Mailing list for gathering anonymous feedback and for getting information.
• Social media presence via E2BA-CSAs LinkedIn group -
• Project page in social media: facebook and twitter
