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).

Note: Community Groups are proposed and run by the community. Although W3C hosts these conversations, the groups do not necessarily represent the views of the W3C Membership or staff.

Access to Reports from LBD related Workshops

The following reports are from a number of LBD related workshops and events which have been held over the past year and with  are now accessible.

The first report covers the BIM Semantic Web/Linked Data Workshop, part of the which was part the buildingSMART International summit which took place from Monday 23rd March to Wednesday 25th March, 2015, at the Building Research Establishment (BRE), Watford, London. The workshop was organized by the following members of the LDAC group and the SWIMing project: Thomas Liebich, Matthias Weise, Pieter Pauwels, Jakob Beetz, María Poveda and Kris McGlinn. It consisted of three sessions: a general introduction session, a requirements and use case descriptions session and finally a summary and formation of working group session.

The second report covers part of the LDAC 3rd International Workshop on Linked Data in Architecture and Construction held in Eindhoven, held on the 16th of July 2015. The LDAC workshop topic was “The use the Web of Data technologies for building information management in diverse practical use cases”. The report focuses specifically on a parallel event held by the SWIMing project around the development of use cases for linked data in energy efficient buildings and also a Hands-on tutorial sessions for participants around converting building data resources to linked data.

The third report summarizes the main aspects of the SWIMing workshop, held on Thursday 17th September, 2015, at the University Campus of Savona, Italy and aligned with Sustainable Places. It also details activities at two related VoCamp workshops; the first on the 14-15th of September, hosted by Ready4SmartCitites and held in Genoa, Italy and the second on the 15–17th of December, hosted by the SEAS project in Paris, France. Finally, a short report is provided regarding the BuildingSMART Conference held on the 12-15 October 2015 in Singapore. The next sections describe each of these workshops.

Dublin, Ireland, March 22-23 2016 – ifcOWL-SAREF-FIEMSER VoCamp

The ifcOWL – SAREF – FIEMSER VoCamp continues the series of VoCamps covering various topics related to the use and development of vocabularies for the implementation of new services in the context of energy efficient buildings. After Adapt4EE and Ready4SmartCities, the SWIMing project has taken over the responsibility for organizing the VoCamps. The event will be organized in cooperation with a number of EU projects, the W3C LBD Community Group and the buildingSMART Linked Data working group. The focus of this VoCamp is to discuss exchange requirements for selected use cases, focusing particularly on the mapping to relevant ontologies like ifcOWL, SAREF, and FIEMSER.

The event will be an excellent opportunity for those involved with the use of the aforementioned ontologies to demonstrate how they apply them, as well as for those planning to use building data in combination with smart appliance data and sensors. Participants will be able to see where and how these ontologies are currently being applied, and how they can be properly linked to their own data in order to meet their own use cases.


Participants are invited to propose, submit, bring and present their own data and ontologies to the VoCamp, especially if there is a clear link with the ifcOWL, SAREF, or FIEMSER ontologies. Throughout the VoCamp, a selected number of these proposals will be presented, together with the targeted use case. Hereafter, a number of ontology engineering sessions will be held, supported by the ReqCap tool, allowing participants to model exchange requirements and mapping definitions into a practically usable result.

First projects that have shown interest in contributing use cases and requirements as well as to share their experiences in using various ontologies are eeEmbedded, Holisteec, Design4Energy (proposed by Dresden University and partners) and the SEAS project (proposed by Ecole des Mines de Saint-Etienne and partners). Other projects are welcome.

LDAC2015 workshop report

LDAC2015 - Group picture

The LDAC2015 workshop report is out. It can be found at This report summarizes the presentations and discussions held during the 3rd International Workshop on Linked Data in Architecture and Construction (LDAC), which took place at the Eindhoven University of Technology (TU/e) in Eindhoven, the Netherlands, from July 15 to July 17, 2015 ( The event was organised by Jakob Beetz at the TU/e. The LDAC workshop typically gathers researchers with diverse ideas about ways in which linked data and semantic web technologies can enhance information exchange in the AEC domain. This third edition did not only host a number of excellent presentations of new work, it also included an excellent technical session and use case session.

The wide umbrella under which the VoCamp will take place is at the cross of the SmartCity domain and the ICT domain which encompasses also the Building sector, Software, Hardware and Data issues for the ICT domains, the Grid, the urban mobility, etc… This VoCamp will concentrate on the alignments of sectorial ontologies to a specific ontology which is also candidate for standardisation (The SAREF ontology – Smart Appliance Reference ontology – that is now in the hands of the ETSI to become THE standard for smart appliances).

Such alignments will be searched/established  within the frame of the predefined scenarios proposed in the Roadmap established by R4SC and they can be (or should be) also related to selected use cases already formalised/described under the W3C Linked Building Data Community Group Activities.

The principle of a VoCamp remain the same. It is an open workshop gathering experts to discuss towards an  agreement. Therefore it is totally free of charge and based on a voluntary basis.

Registration is simple as an email sent to address:
