In the domain of architectural design and building science, immersive virtual environments are adopted to facilitate architects and building engineers to enhance the design process through assimilating their sense of scale, depth, and spatial awareness. Such platforms integrate the use of virtual reality models and mixed reality technologies in various functions of building science research, construction operations, personnel training, end-user surveys, performance simulations and building information modeling visualization. Head-mounted displays (with both 3 degrees of freedom and 6 degrees of freedom systems) and CAVE platforms are used for spatial visualization and building information modeling (BIM) navigations for different design and evaluation purposes. Clients, architects and building owners use derived applications from game engines to navigate 1:1 scale BIM models, allowing a virtual walkthrough experience of future buildings. For such use cases, the performance improvement of space navigation between virtual reality headsets and 2D desktop screens has been investigated in various studies, with some suggesting significant improvement in virtual reality headsets while others indicate no significant difference. Architects and building engineers can also use immersive design tools to model various building elements in virtual reality CAD interfaces, and apply property modifications to building information modeling (BIM) files through such environments.
