URBAN STREETSCAPES RESPONDING TO CHANGING CLIMATE CONDITIONS-EFFECTS OF STREET LAYOUT ON THERMAL EXPOSURE

This contribution explores the effects of climate change on open spaces and street canyons in urban environments, using the “Aspern” New Town development in Vienna as a principal case study. Specifically, the effects of alterations in the urban fabric are analysed with regard to sun exposure and ventilation. Results of future regional climate scenarios are incorporated in a second series of microclimate simulations. Future climate conditions are based on regional climate simulations for the years 1960-2050, carried out by the authors in previous studies. Microclimate conditions are simulated with the ENVI-met tool, simulating climate dynamics within a daily cycle reproducing the major microscale atmospheric processes, based on the laws of fluid dynamics and thermodynamics. 3D-block models of the planned Aspern development with 5m cell resolution are introduced to consider effects of different spatial characteristics due to block layout and tree distribution at a local level.
