“…After an introduction to the related research on thermal comfort and climate change, IFC-based BPS, and future weather scenarios, we present our approach for IFC-based thermal comfort simulation. This approach extends the existing IFC-based BPS approach bim2sim [9,10]. A set of thermal comfort parameters for template-based BPS model enrichment supports the presented bim2sim extension.…”

“…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].…”

“…With its modular and open-source approach for IFC-based BPS simulations, the bim2sim tool [9,10] provides a solid base for adapting the EnergyPlus-based BPS methods toward thermal comfort analysis. The bim2sim tool aims to support engineers with a geometric and semantic simulation model setup using IFC and template-based data.…”

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.

“…In short, bim2sim is a tool that includes methods and concepts to read data from an IFC file, convert it to a simulation-oriented meta-class structure by collecting as much information as possible from the IFC, perform various types of processes and simplifications on the meta-classes, and export the results to a simulation model. This process can be used for HVAC simulations as presented here, but we also implemented methods and concepts to perform Building Performance Simulation (BPS) .The basic idea was already published [15] as well as the application on BPS [5,16]. The workflow that is used specific for HVAC simulation is shown in figure 1.…”

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.
