Urban sprawl is an essential environmental issue to be monitored and forecasted in order to think about alternatives that could lead to a more sustainable future development. Thus, the objective of the project presented here is to simulate the past and future transformation of suburban land use patterns in the Vienna Region. (The paper describes some(More)
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(More)
The paper discusses a model that performs the simulation of polycentric development of suburban systems. It introduces different settlement pattern growth speeds in different suburban regions considering housing area densification and land use change from open space to built up area. Accordingly, the approach concentrates on a Spatial Agent Model (SAM) to(More)
As climate change appears, strategies and actions will be necessary to cope with its effects on environment and society in the coming decades. Current climate conditions can be observed everywhere in the world but future climate conditions can only be estimated through climate simulations which produce huge amounts of quantitative data. This data leads to(More)
Using an existing decision support system in different data availability situations is a challenge. This is due to the significant variance in terms of what data can be acquired as input for such systems. In urban energy planning, the problem of data availability is even more crucial because of the large amount of data that is required. This problem affects(More)
Considering the large amount of energy consumption in cities, two-thirds of the overall consumption, these latter have an important potential in terms of CO 2 emissions reduction. Therefore, energy strategies are needed at a city level and consequently, adequate planning tools are required to support urban energy planners in assessing their decisions (e.g.(More)
Climate sensitive urban planning and building design require detailed information on effects of a changing climate. To simulate thermal building performance appropriate data are required as " standardized weather files ". But as historic weather records cannot be used to model building performance for future climate, synthetic " future weather " data are(More)
