Integrating Virtual Reality and BIM for End-User Involvement in Design: A Case Study
Abstract: The outcome of projects within Architecture, Engineering, and Construction is highly dependent on the quality of the collaboration between the involved actors. The end-users occupy the buildings on a daily basis, and therefore their involvement in the design process is essential to the output. However, traditional practices place the responsibility of decision-making mostly in the architectsÕ hands. Virtual Reality technologies coupled with Building Information Modelling have the potential to improve the collaboration and data visualization in the building design.This paper presents the findings from a case study on the integration of Building Information Modelling and Virtual Reality for user-centred participatory interior furnishing of a new university building. Besides a significant reduction in the time for generation of alternative proposals, the end results show an increased attachment of the employees to their future workplace and a high level of acceptance towards the technology. Finally, the authors present suggestions for further work, which could improve future design processes utilizing the Virtual Reality technology.

Proposing a Central AEC Ontology That Allows for Domain Specific Extensions
Abstract: In the last years, several ontologies focused on structuring domain specific information within the scope of Architecture, Engineering and Construction (AEC) have emerged. Several of these individual ontologies redefine core concepts of a building already specified in the publicly available ontology version of the ISO standardised Industry Foundation Classes (IFC) schema, thereby violating the W3C best practice rule of minimum redundancy. The voluminous IFC schema with origins in a closed world assumption is likewise violating this rule by redefining concepts about time, location, units etc. already available from other sources, and it is furthermore violating the rule of keeping ontologies simple for easy maintenance. Based on all the available ontologies, we propose a simple Building Topology Ontology (BOT) only covering the core concepts of a building, and three methods for extending this with domain specific ontologies. This approach makes it (1) possible to work with a limited set of core building classes, and (2) extend those as needed towards specific domain ontologies that are in hands of business professionals or domain-specific standardisation bodies, such as the European Telecommunications Standards Institute (ETSI), buildingSMART, the Open Geospatial Consortium (OGC), and so forth.
