Entwicklung einer Virtual Reality‐Umgebung zur interaktiven thermischen Raumsimulation.

Development of a virtual reality environment for interactive thermal room simulation This article describes an approach in which the modeling and simulation process for the indoor climate of buildings takes place entirely in a virtual reality (VR) environment. In this way, the simulation expert is immersively involved with regard to the spatial design, spatial perception and interaction with the spatial model. The simulated indoor climate resulting from the interactions and other variables such as energy demands are visualized in the VR environment as a feedback to the user. To implement the described approach in terms of software, the Modelica tool Dymola was integrated with the game engine Unity to form a complete system, with bidirectional data exchange taking place between the two programs. The building model of the Modelica library BuildingSystems forms the basis of the building physics calculations in Dymola. In Unity, a head‐mounted display was integrated to implement the VR simulation environment, and the two modes "modeling" and "simulation" were prototypically implemented and evaluated in a simulation scenario.
