“…The study conducted by Choi et al (2023) proposed a plan to generate alternatives and assess energy performance by analyzing the envelope shape of amorphous buildings through IFC [68]. Furthermore, more agile methodologies, based on the graph technique, are outlined to enable automation in the field of BEM with less inconsistency and interference [69]. The inclusion of domains not traditionally related to BIM encouraged the development of interoperability that would allow different project actors to facilitate the integration of their know-how and the import/export from one BIM tool to another.…”

Representation and modeling using the building information modeling (BIM) methodology of civil works have become the subject of increasing attention in recent years, thanks to the potential offered by Open Infrastructure BIM (I-BIM). However, the complexity of infrastructure works, i.e., the variety of construction and technological systems, makes Open I-BIM very complex and challenging. The lack of systemic knowledge on the subject is another challenging factor. The aim of the following research work is to provide a synoptic overview of the existing scientific research, accompanied by the most recent studies in the field of computer modeling, its applications, and the main opportunities that Open I-BIM offers to the infrastructure sector. After a thorough review of 198 scientific articles published between 2013 and 2023, this study systematically presents a holistic review and critical reflection on the current status of the use of Open BIM in the infrastructure sector, with a focus on the development of the tools and methods used. The outcome of this work constitutes a systematic review of the literature with a bibliometric analysis on Open I-BIM, which is able to provide a knowledge base for identifying research trends, common problems, and the potential of developed methods.

“…These space boundaries describe the virtual heat-transmitting surfaces in-between thermal zones and the building's surroundings, considering adjacent thermal zones and building constructions. While some studies discuss methods for generating second-level space boundaries for building simulation [33][34][35][36][37][38][39] or directly integrate space boundary generation methods in their IFC-based BPS approaches [39][40][41], other studies rely on the IFC4 schema-conform definition of space boundaries for the (semi-)automatic generation of BPS models [9,[42][43][44][45]. To be able to rely on the quality of provided space boundaries, a validation and/or a correction process may need to be applied, as proposed by Ying and Lee [29], Richter et al [30].…”

Future weather scenarios significantly affect indoor thermal comfort, influencing people’s well-being and productivity at work. Thus, future weather scenarios should be considered in the design phase to improve a building’s climate change resilience for new constructions as well as renovations in building stock. As thermal comfort is highly influenced by internal and external thermal loads resulting from weather conditions and building usage, only a dynamic building performance simulation (BPS) can predict the boundary conditions for a thermal comfort analysis during the design stage. As the model setup for a BPS requires detailed information about building geometry, materials, and usage, recent research activities have tried to derive the required simulation models from the open BIM (Building Information Modeling) Standard IFC (Industry Foundation Classes). However, even if IFC data are available, they are often faulty or incomplete. We propose a template-based enrichment of the BPS models that assists with imputing missing data based on archetypal usage of thermal zones. These templates are available for standardized enrichment of BPS models but do not include the required parameters for thermal comfort analysis. This study presents an approach for IFC-based thermal comfort analysis and a set of zone-usage-based templates to enrich thermal comfort input parameters.

“…The idea of using data models from digital design and, in particular, BIM data is not new. Especially in the field of thermal building simulation, there are already various approaches to avoid redundancy in the double modeling of planning and simulation models [3][4][5][6][7]. In the area of hydraulic-focussed energy simulations or Heating, Ventilation and Air Conditioning (HVAC) simulation in general, the number of existing approaches is smaller.…”

The construction of energy-efficient buildings is one of the most important measures to reduce the impact of buildings on our environment. The dynamic simulation of the energy systems of these buildings can improve the design and performance and thus reduce the emissions that impact the environment. However, the process of creating models for dynamic simulations is time-consuming and error-prone. By using already existing digital models from the planning process the process of model generation can partially be automated. This paper presents the tool bim2sim and its underlying methodology for the application of automatic model generation for dynamic hydraulic energy system simulation with Modelica based in Building Information Modeling models with the open exchange format IFC. The tool is applied to the use case of an example energy system and a manual comparison modeling is performed for the energy system in Modelica. The comparison shows that automatic model generation saves a significant amount of time even for comparatively simple systems.
