Development of an interactive virtual reality simulation environment with a thermal feedback for the user

Abstract

This contribution describes the first experimental results of the development of a virtual reality (VR) simulation environment, in which the users are immersively embedded in a 3D visualization of the building model and experiences the simulated indoor climate of the associated thermal simulation model physically as thermal feedback. The users can interact with the room model in the VR environment (e.g. open a window) and thus influence the room energy and moisture balance. To implement this approach, a Modelica-based building model was coupled with the game engine Unity in real time. These interactions cause a change in the physical state of the building model. The calculated current indoor climate is generated in the VR simulation environment for the users by several air conditioning devices and made physically experienceable for them.
