Development and application of mitigation and adaptation strategies and measures for counteracting the global Urban Heat Islands phenomenon (UHI)
Date du début: 30 avr. 2011, Date de fin: 29 avr. 2014 PROJET  TERMINÉ 

As population of our cities grow, so does land area and this result in increase of an average temperature. The buildings and roads absorb temperature produced during the day, like giant heaters, and store it. The energy is then released during the night time. This often means a big difference in the temperature between city and its surrounding areas.This phenomenon is called the Urban Heat Island (UHI) and is known and studied since eighties. It is caused by various factors like physical characteristics of the surfaces, where thermal and radioactive proprieties of the materials of urban surfaces, such as concrete and asphalt, absorb rather than reflect solar radiations, or it can be caused by lack of natural evaporative surfaces (vegetation), or by increase of the vertical surface that both provide an increased surface absorbing and reflecting solar radiation as well as block wind (canyon effect) 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. The UHI effects are directly related to (and worsened by) the climate change, with stronger and immediate effect on the health of people living in cities.The project UHI, which started from a deep analysis of this phenomenon carried out with traditional micrometeorology techniques and remote sensing techniques, is designed to both develop mitigation and risk prevention and management strategies to tackle this problem. Achievements: UHI project aims at raising the transnational attention, as well as to trigger the elaboration of plans and practical actions, for the prevention, adaptation and mitigation of the natural and man-made risks, arising from the urban heat islands phenomenon. The UHI innovative character is to make interacting two disciplines that are traditionally strangers one to another: meteoclimatology and urban planning, towards the definition of particular strategies able to guide the choices of development and urban renewal. In this regard the created transnational network (Transnational Scientific Board) dealt and agreed shared methodological approaches. The UHI project has entered in its crucial implementation phase. Many deliverables have been achieved and agreed among Partners, but many of them are still under discussion. Thanks to the Transnational Focus Groups work organized beside the Steering Committee meetings, the Partners had the possibility to debate and share deeply different opinions and points of view. The Transnational Focus Groups function is indeed to trigger the dialogue and coordinate the discussion within a thematic approach. In particular, to raise the partners attention on the importance of disseminating the project message and organizing their local events, during the Transnational Focus Groups in Prague, the partners have been asked to deal with the issue Transnational versus Local perspective: experiences of the different Local Working Groups, using a . smart methodology/tool (UHI Prezi ) activated by the LP as free co-working platform useful to facilitate the knowledge exchange and define their own strategies at local level. Main project outputs achieved during this period have been the UHI versus climate change report, that shows different approaches on how to simulate the Urban Heat Island phenomenon for Central European cities, and the Gold Standard as methodology to analyze the Urban microclimate. As regard the pilot actions, despite the problems due to political decisions to be taken internally by the public Administrations involved, but also in relation to the difficulties of some PPs in matching with the institutional administrations concerned, many progresses have been achieved and the specific work carried out by each area is free available through the UHI project web site within its specific section devoted to the pilot actions
