The urban heat island (UHI) is a microclimatic phenomenon that occurs in the metropolitan areas. It consists in a significant increasing of the temperature in the urban area respect to the surrounding peri-urban and rural neighborhoods. This phenomenon is known and studied since eighties and is caused by:

  • physical characteristics of the surfaces: because of the thermal and radioactive proprieties of the materials composing urban surfaces, such as concrete and asphalt, that absorb rather than reflecting solar radiations;
  • lack of natural evaporative surfaces (vegetation) that, in rural areas, contribute to maintain a stable energy balance;
  • augmentation of the vertical surface that both provide an increased surface absorbing and reflecting solar radiation as well as block winds that could contribute to the lowering of the temperature (canyon effect);
  • human activities that mainly consists in heat produced by heating and cooling plants, industrial activities, vehicles, etc.

The intensity of UHI phenomenon rises proportionally to the dimension and population of the urban area; consequently, it is doomed to become more severe in the coming years due to the constant growing of number of people living in urban areas and has a strong and immediate effect on the health of people living in cities. The UHI effects are directly related to the climate change phenomena as well.

The UHI project, starting from a deep analysis of the phenomenon carried out with traditional micrometeorology techniques and remote sensing techniques, is designed to both develop mitigation and risk prevention and management strategies.

The general objective of the project is to trigger the elaboration of policies and practical actions to reduce the impact of UHI phenomenon. This is an issue common to all large urban agglomerations in Central Europe area.

Project aims are: 1) to establish a transnational attention for the prevention, adaptation and mitigation of the risks arising from this micro-climate phenomenon, 2) to tackle UHI issue moving European policies towards a more responsible use of our environment. This will be done addressing global warming impact on urban environment and citizen life. Outcomes will be on the one hand rules and policies for planning new urbanizations less exposed to UHI phenomenon and on the other hand action plans to mitigate the impact of UH on citizens' health.

Project output actions will bring CE cities towards more sustainable urbanization model: they'll be less exposed to UHI phenomenon, so improving life quality but also decreasing energy costs (for summer cooling) and health care system ones (for sensible populations). UHI project helps CE's cities to set measures to become attractive places to invest in and to live in.

UHI project is carried out in 8 most relevant metropolitan areas and MEGAs (Mega Urban Regions) of Central Europe cooperation programme: the metropolitan cluster of Bologna – Modena (IT) and the urban corridor of Venice – Padua (IT), the cities of Wien (AT), Stuttgart (D), Lodz & Warsaw (PL), Ljubljana (SI), Budapest (HU) and Prague (CZ).
