BIM and Mixed Reality for Visualizing Building Energy Data

Abstract: The visualization of building energy data is an open topic, intuitive approaches are rare and new concepts are required to handle big data collected by more and more sensors or even derived from energy simulation results. The interpretation of data, either derived from a monitoring system or from building simulation analysis, can be difficult to handle. Combining geometrical data and energy data into a visualization interface could be a promising way to help designers and facility managers to better understand the use of different spaces, enabling a higher efficiency of building management. In this paper, an application for visualizing monitoring data or simulation results by means of Mixed Reality and BIM is presented. For the purpose, a doll's house concept (third-person observer) has been adopted as a container for the visualization of energy data in a geometrical context. Timeseries based interactive diagrams, derived from monitoring system or simulation results, are integrated into geometrical holograms of buildings or parts of buildings (like floors) and they allow intuitive working. Moreover, multiuser scenarios applying cloud anchors are supported. The geometrical models are retrieved by applying Building Information Modelling (BIM).
