Article
The digitalisation of the Architecture, Engineering and Construction domain introduced new methods for digital collaboration, i.e. Building Information Modelling (BIM). While this method focuses on building data, the distribution of digital product models is still problematic, complicating uniform product searches and automated product data process...
Conference Paper
The advancing digitization in the building industry highlights weak points in the digital infra-structure. Due to heterogeneous software landscapes, cross-application data exchange is a frequently criticized process in particular, for which no satisfying solution exists so far. Open and application-independent data formats are necessary, and theref...
Conference Paper
Model checking is an important task in the BIM collaboration process to prevent expensive planning errors. The submodels of the individual disciplines are transferred into a coordination model. Part of the transfer is a conversion into an exchange format. The exchange format allows the import into the model checking application. In the model checki...

Collaboration is the intrinsic element of the construction industry since construction projects involve a dynamic grouping of several companies. [1] studied the relationships among the companies and noted that some communication patterns among participants show a Peer-to-Peer nature. Digital technology which implements this Peer-to-Peer communicati...

http://docs.ogc.org/wp/19-078r1/19-078r1.html The purpose of this document is to outline the benefits of representing geospatial data using semantic and graph technologies. It aims to provide motivation for OGC members to consider the publication of geospatial data using these technologies.
Article
The exchange of construction-related data over the Web via Semantic Web Technologies is gaining interest in current research. However, most research focuses on non-geometric data, neglecting the description of geometry. While several methods to include geometry descriptions into a Semantic Web context exist, no uniform approach or general recommend...

Presentation
Full-text available
This is my PhD defence on the topic of Linked Building Product Data and the three ontologies I developed therefore: The Building Product Ontology (BPO) for generic product descriptions, the Ontology for Managing Geometry (OMG) for relating non-geometric objects to geometry descriptions, and the Ontology for Parametric Systems to define equation-bas...
Conference Paper
Full-text available
With the current trend of using Linked Data to describe buildings during their entire lifecycles, the importance of product descriptions in a Semantic Web context is growing while most product ontologies are designed for mass-produced goods of little variance. But especially in the construction industry, products are often innovative and individual...
Conference Paper
Full-text available
Digital planning methods are changing the needs of construction stakeholders. It should be as easy as possible to compare product data from different manufacturers and integrate them into the planning model without detours. Web technologies not only offer great potential to enhance existing ways of working, but also open up new business models for...
Article
Geometric data plays a central role in the geospatial domain, architectural design and construction industry. For upcoming, new approaches to store building data, such as the Semantic Web, no universal common agreement exists on the combination of geometric and non-geometric data. It can therefore be unclear to users on how to represent their geome...
Conference Paper
Full-text available
Multi-functional façade components allow extending façade functionalities from the building's physical appearance towards multiple other fields (e.g. HVAC, electric system). Integrating those complex products into the building design and planning phases, however, is not yet supported well enough to make their application feasible. To facilitate man...
Conference Paper
The research project Solar Construction Processes (SolConPro) focusses on developing new methods to facilitate planners in integrating solar active façade components, e.g. building integrated photovoltaics (BIPV) and building integrated solar thermals (BIST), into the building processes. The decisive feature of such components is that they reunite...

With regard to the use of renewable energies, facades offer great potential. Due to the existing and commonly unused facade surfaces, conversion surfaces can be created by using multi-functional facade components, especially in heavily populated areas. However, the use of the multi-functional components with current BIM-methods is complex and expensive, which is why the usage of façade surfaces for energy generation in urban areas has not been able to prevail on a large scale so far. The reasons for the complexity of applying such components are numerous, but the main points to name are the strong need for cross-company and cross-disciplinary collaboration, the lack of existing or insufficiently supported digital product descriptions and the flood of information generated by such complex products. Although these challenges are particularly evident when considering multi-functional components, they generally affect the entire construction process. Within the research project SCOPE (Semantic Construction Project Engineering) approaches that relate to the product and building life cycle are developed. At the center of these approaches stands an application-independent data management, which will facilitate collaboration between different project partners using different software applications. In order to achieve this, schematics for the description of product and project data as well as concepts for a decentralized data management (e. g. for a product catalogue) are developed. To ensure data security, said data will be provided with an access rights management system, and interfaces for secure data exchange are defined. To allow an easy integration of the product and building model into existing software, preprocessing routines are designed to reduce information and transform data. These should have a modular structure to allow a high re-usability and a wide field of application. The developed methods and concepts are implemented demonstratively and used in example projects. Findings on possibilities for improvement identified from these test runs will be taken into account in the course of the project within iterative steps for the further development of the methods. The research project will be jointly conducted by the Fraunhofer-Institut für Solare Energiesysteme ISE, the Institute of Numerical Methods and Informatics in Civil Engineering at the Technische Universität Darmstadt and the Ed. Züblin AG edited. In addition, associated partners from the considered disciplines as well as ITC Engineering GmbH & Co.KG are involved in software development. The joint research project is funded by the Federal Republic of Germany with the German Federal Ministry for Economic Affairs and Energy (BMWi) as awarding authority based on a resolution of the German Bundestag. https://www.projekt-scope.de/

The commencement of the “Erneuerbare-Energien-Gesetz” (EEG) in 2000 by the German government is the foundation for the extension of renewable energies representing an essential element of the energy transition. Pursuing the goal to achieve a share of at least 80 percent of renewable energies in the power supply by 2050, the EEG protects the climate and environment as well as it conserves fossil energy resources [Source]. Beyond that, the German government declared the ambition to reduce the greenhouse emissions in comparison with 1990 by not less than 40 percent until 2020 and 80 till 95 percent until 2050 [Source]. Large surface areas are necessary for the conversion of wind and solar energy to that end, which engenders substantial encroachments to the nature. At this juncture roofs and facades provide an enormous potential. By an increasing utilisation of new and existing building envelopes to generate electricity and heat from solar energy the additionally required space for renewable energies can be decreased. Despite the increasing appeal to use solar components caused by the cost degression of the PV industry of recent years an economic and reliable integration in the building envelope has not been achieved yet. A holistic integration of facade integrated PV and solar thermal components into the construction process chain is missing. The fragmentation of the planning process and a non-consistent joint use of data in planning, implementation and operation complicate the application of active components in facade or roof of a building. The research project Holistic Integration of Energy Active Facade Components in Building Processes aims to develop and analyse solutions promoting the integration of energy active components into the building envelope. Thus we will consider ways and means for involving these components into the early planning process in order to produce informative simulations. Aside from that the data communication transferring the various project stages and partners must be permanently guaranteed. Therefore an extension of the methodology of Building Information Modelling (BIM) to allow a complete and permanent endorsement of active PV and solar thermal components will be our focus. Involved parties of this research project are the Fraunhofer Institute for Solar Energy Systems ISE, the Institute of Numerical Methods and Informatics in Civil Engineering at the TU Darmstadt and Ed. Züblin AG. The research project is funded by the “Bundesministerium für Wirtschaft und Energie” based on a government’s decision. More information can be found at www.solconpro.de
