Abstract:

The worldwide impacts owing to global change are already noticeable. Particularly striking are global environmental changes such as climate change, deforestation and biodiversity loss. The rapid rise of population growth caused great resource scarcity. This problem lead to a migration from rural areas into the cities. The urbanization demanded the construction of skyscrapers, the modification of land surfaces and the expansion of transportation networks. Increasing anthropogenic CO2 emissions and a change in the radiation balance led to the urban heat island effect. This is even higher than the expected temperature increase due to climate change. Local and micro-climatic heating effects form the core of the heat island effect. There are worldwide studies investigating how different urban structures contribute to urban climate. Equally the impacts on human bodies are the focus of investigations. For the future it will be important to find ways to limit and prevent heat stress in cities. Within the scope of this thesis local climatic investigations were conducted during summer 2015 on eight sites at the campus of the University of Natural Resources and Life Sciences in Vienna. Weatherstations recorded the air temperature and relative humidity over several months. Besides, the wind speed, surface temperatures, the illumination intensity and the heat stress were quantified with mobile measurements during heat waves. Infrared-images of the measurement locations were made and the sun orbits were determined. The sites were assigned to local climate zones according to their properties. Data from the university´s weather station was used for comparison and to expand the measurement values. The results show clear influences of structural and meteorological elements on the air temperature. The heat stress on BOKU-terrain is not negligible on hot days, whereby physically demanding activities should be avoided. Due to local characteristics temperature differences of up to 4.5 °C were recorded.
