Invisible environmental factors, such as air pollution, are hard to present in a comprehensive way, and consequently these questions often get low priority in urban planning processes.

Main research question(s): In order to create a better understanding for e.g. air pollution at street level, a visual concept for 3D city models needs to be developed, where a walk through perspective at street level with pollution levels is included.

Method(s) for co-production: An urban area in central Gothenburg was studied regarding the quality of air following changes in the built environment. The area is planned to be reconstructed in the near future and it was selected in co-operation with representatives from the City Planning office. The air pollution visualization will hopefully be integrated in the 3D city model of Gothenburg.

Main findings: The results explore different ways to represent environmental factors in 3D-city models. Spreading calculations for particles were carried out, based on the plan for new buildings in the area.
