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).

This year the LDAC Committee, with the support of the Linked Building Data Community, hosted the first Summer School of LDAC alongside the 7th LDAC Workshop, in a week-long programme hosted by the Design and Computation Group of the Faculty of Architecture – University of Lisbon. The event took place at the Beta-i Hub in Lisbon, between June 17-21, 2019.
The first Summer School of LDAC was dedicated to the application of semantic web, linked data and web of data technologies in architecture, engineering and construction (AEC). Considering the growing interest in these technologies from the AEC industry and research institutions, this Summer School provided a starting point for participants that are new to the topic entirely and the opportunity to enhance the understanding and overview of implementations and approaches in the built environment for participants that wished to deepen their knowledge in this field.
With a mixture of lectures, personal interactions with experts in the field, hands-on exercises and coding challenges, the Summer School gave participants the opportunity to explore the possibilities of the semantic web, linked data and web of data technologies for their own research and practice needs at their individual pace and depth.
An integral part of the summer school was the application and strengthening of newly learned knowledge from lectures in practical research work: The Coding Challenge. The goal was for participants, grouped in interdisciplinary teams, to address and define real-world problems. The coding challenge prize was generously sponsored by Stardog.
The 7th LDAC Workshop followed usual set up with keynotes by Ruben Verborgh and Ora Lassila, plenty plenary sessions dedicated to research in LBD, the technical track dedicated to W3C LBD Community Group content, and the industry track with presentations from LBD applications in companies from the AEC industry.

We wish to strongly encourage members of the W3C LBD Community Group to participate!
This year’s LDAC workshop takes place at the University of Burgundy, in Dijon (France). In this workshop, the main aim is to evaluate the current status of the different available ontologies to capture building data. This includes many of the ontologies currently under development in the W3C Linked Building Data Community Group. Aside the development and usage of these ontologies, the purpose of the LDAC workshop is to also investigate ways in which the ontology-based data can be combined into a complete and holistic set of available building data. Finally, and most importantly, a number of industrial cases are invited, aiming to give an indication of the effect of these ontologies on every day practice in managing building data (design, construction, facility management, smart cities).
