Community & Business Groups

Linked Building Data Community Group

This group brings together experts in the area of building information modelling (BIM) and Web of Data technologies to define existing and future use cases and requirements for linked data based applications across the life cycle of buildings. A list of recommended use cases will be produced by this community group. The envisioned target beneficiaries of this group are both industrial and governmental organisations who use data from building information modelling applications and other data related to the building life cycle (sensor data, GIS data, material data, geographical data, and so forth) to achieve their business processes and whom will benefit from greater integration of data and interoperability between their data sets and the wider linked data communities. For example, benefit may be obtained by publishing and combining localised data on new cheaper building materials, energy efficient building devices and systems, along with real time data on weather patterns, energy prices and geodata. By making this data available to applications, they will be better able to support decision makers during the whole of the building life cycle, which includes design, construction, commissioning, operation, retrofitting/refurbishment/reconfiguration, demolition, and recycling of buildings. The group will engage with these beneficiaries through surveys and events organised in conjunction with the affiliated workshop series on Linked Data for Architecture and Construction (LDAC).

Joint Conference CIB W78 – LDAC 2021 (Linked Data in Architecture and Construction Workshop) – Call for Papers

The Joint Conference CIB W78 – LDAC 2021 will take place in Luxembourg between 11-15 October 2021 and is associated with the International Council for Research and Innovation in Building and Construction (CIB), its Working Commission W78 on Information Technology for Construction and the Linked Data in Architecture and Construction research community. This event is organized by the Luxembourg Institute of Science and Technology (LIST) in collaboration with Cardiff University (UK) and the European Construction Technology Platform (ECTP).

The 38th CIB W78 conference on Information and Communication Technologies for AECO and the 9th LDAC workshop aim to bring together an international community of researchers and industrials interested in the areas of Construction Informatics, BIM, Digital Twin and Knowledge Management. The scope of the conference is broad in terms of the design, construction and operation and occupancy of constructed facilities, but it primarily relates to the integration and communication of data, information and knowledge in the life cycle of a facility.

CALL FOR PAPERS | Extended deadline
The call for papers for the CIB W78 and LDAC 2021 is open. The abstract submission deadline is extended to 15 February 2021! Abstracts will only be accepted though the online abstract submission system. More details on the dedicated website.

W3C LBD CG meets… Jereon Werbrouck – Scan-to-graph: Semantic enrichment of existing building geometry

The W3C LBD CG has been happy to welcome Jereon Werbrouck from Ghent University concluding the selected-topics-in…-series with his presentation on Scan-to-graph: Semantic enrichment of existing building geometry. In his excellent presentation he discribed how the scan-to-BIM process can be realised in a Semantic Web context and how Linked Data technologies allow to address problems from integrating heterogeneous data sources as well as allow to keep track of assumptions and uncertainties in the process. He concluded his presentation with a live demo of the LBDServer, a open-source implementation of the aforementioned functionalities. See the minutes for the details!

Exchange Accessibility Information on the Web

In this weeks call the members of the W3C LBD CG were happy to have Holger Dieterich and Sebastian Felix Zappe from W3C LDA CG as guests presenting an amazing effort towards using digital technologies to easen the daily life of people with reduced mobility by distributing accessibility information on the web.

The two pointed to their work on developing a11yjson, a JSON based datamodel to describe accessibility information on the web. They plan to formalise this format using Linked Data and Semantic Web Technologies and a potential collaboration with W3C LBD CG should focus on the linking to Building Topology Ontology (BOT).
