The Special Issue of Automation in Construction is about why and how to use the Web of Data technologies (RDF, OWL) for building information management (BIM). The article by Radulovic and colleagues, Guidelines for Linked Data Generation and Publication: an Example in Building Energy Consumption, focuses on making a set of guidelines available regarding the proper generation and publication of linked data, aiming specifically at the context of energy consumption in buildings. The article by Terkaj and Sojic, Ontology-based Representation of IFC EXPRESS rules: an enhancement of the ifcOWL ontology, gives a detailed indication of how the recent actions towards the development of an OWL version of the IFC schema can be extended to consider IFC EXPRESS rules. Costa and Madrazo combine both types of information in their article, named Connecting building component catalogues with BIM models using semantic technologies: an application case for precast concrete components, aiming to assist the design team in the assembly and dimensioning of structural components during the project phase. The third article included in this Special Issue is presented by Corry and colleagues, entitled, A performance assessment ontology for the environmental and energy management of buildings. In this article, an investigation is made of the ways in which semantic web technologies can be used to combine all sorts of energy-related data in buildings, so that the performance gap between measured and simulated energy performance level of a building can be made to increase.

Current specifications for facility handover information require contractors to produce and deliver a set of documents that provide little practical value to the facility manager. Facility managers begin their duties by rekeying the information found in these handover documents. This paper describes the facility management handover (FM) model view definition (MVD), an open-standard information exchange format that may replace current construction handover document requirements. The work was accomplished in conjunction with three buildingSMART chapters to ensure the widest possible international acceptance. The specification of the underlying industry foundation class (IFC) model with required business rules for use in the United States is called the construction-operations building information exchange (COBie) format. Procedures used to test software production and consumption of COBie were developed. Use of COBie has now been documented in several case studies. © 2013 American Society of Civil Engineers.

Integrated analyses and simulations of building energy system performance throughout thewhole lifecycle can be efficiently achieved only if a sound integration approach with regard to the needed underlying data is provided. This data is highly distributed and heterogeneous, thereby implying the use of multiple models and resources. In this paper, we present the concept of a suggested multi-model framework that enables the targeted data and ICT tools integration. Described are the development methodology based on the IDM approach, the considered processes and use cases, the overall concept of the suggested framework, the envisaged information exchange on the integration platform and a first implementation prototype. The presented research is performed in the frames of the EU Project HESMOS (2010-2013). © 2012 Taylor & Francis Group.

In this paper we are reporting on a prototypical implementation of a model view checker for model instance validation of Industry Foundation Classes (IFC) models. This checker is developed based on the open standards mvdXML as the format for structuring validation rules and the BIM Collaboration Format (BCF) to issue reports as a result of the checking process. The checker is implemented on top of the open source bimserver.org framework. The research presented here has two main aims: (1) to develop an open source IFC validation tool based on flexible and standardized method; (2) to identify issues and capabilities of the current mvdXML rules based on real-world scenarios and to develop stable and easy-to-use IFC validation methods using open standards. Two BIM operational standards required by local building regulations and laws, the Dutch Rgd BIM Norm, and the Norwegian Statsbygg BIM Manual are used to validate both the mvdXML standards' capabilities and the tools implementation. The rules from these standards are categorized into different rule types and converted to mvdXML templates and rules. These rules are then tested using a prototypical, open source software tool. By combining this tool with a BCF server we demonstrate the deployment of such automated checking procedures in real working processes. Based on these experiences, a detailed discussion about identified issues is provided as the starting point for the future research and a feedback to standardization organizations.
