Abstract: Thermal comfort greatly affects the condition of occupants in buildings. Still, during building design, thermal comfort is often neglected, as the simulation of input parameters takes time and manual effort. To enable an automated IFC-based simulation set-up, we identify simulation approaches to derive the inputs required for thermal comfort analysis. A hierarchical approach selects the simulation's input parameters if input from given IFC files is unavailable.We propose a framework that maps these simulation approaches, input requirements, and comfort metrics to maturity stages from early to detailed design. Within the design process, our framework assists 1) in defining data exchange requirements and 2) selecting comfort metrics based on given IFC data.
