Toward a Unified Representation System of Performance-Related Data

Figure 1: Visualization techniques combined to simultaneously convey a number of performance-related values. An environmentally-responsible building is not a fixed ideal but a moving target that must be reassessed on an ongoing basis in order to respond to the ever changing patterns of its occupants and its context. Instrumented buildings can generate a tremendous amount of data that can play a key role in gaining insight into their changing behaviour and performance. Although visualization has been used as a technique to interpret this data, representation strategies have been limited to 2D graphs or abstract numerical outputs. In this paper, we integrate a set of well-defined interactive visualization methods into one unified framework where a number of inputs pertaining to building performance data can be simultaneously visualized. Furthermore, we display how this integration allows directly relating both spatial and non-spatial data on top of a high-resolution 3D model in order to provide a rich context for more holistic visualization of interacting performance factors
