HLRS's visualization tools can support architects, engineers, and, planners in designing better buildings. Our platform can integrate computer aided design (CAD), building information management (BIM), simulations, and environmental datasets to develop a comprehensive, immersive model of how a building will function. Once implemented in virtual reality, the developers can move through a building virtually, gaining a more immediate understanding of how it will function and be experienced. This approach can help to identify potential opportunities for optimization and even avoid costly design mistakes before construction begins.
