Urban Cool Down

Urban Cool Down

The objective of the project “Urban Cool Down“ is to define new ways, how a comprehensive cooling can be achieved and how an overheating of urban places can be countered. In two case studies the town Wolkersdorf in Lower Austria and the 18th district of Vienna are to prove the cooling effect by landscape planning and open space planning measures in the combination with innovative cooling technology.

This approach focuses on strategies of the alternative city planning, green and blue infrastructure and cooling techniques and connects the topics mobility, energy and water management. Two strategies are the foundation of the project:

  1. Enhancement of the local city climate on small-scale object plane through green and open spaces: Participatory conception of green areas in the public space which function as “cooling oasis” and can be used for lingering, staying or playing. The application of new and innovative cooling techniques like solar cooling, compression refrigeration systems with PV installation as well as natural and traditional shadowing and cooling options are examined. The “cooling oasis” fulfill more functions like places to halt and linger and can be realized in different locations, like squares, parks, queuing areas and transformed parking spaces, in order to make the stay outside despite heat attractive.
  2. The network of green spaces on the large-scale landscape planning level causes an upgrading of the pedestrian system through the city and links green routes (for example greened pedestrian and bicycle lanes, promenades and pergolas) with the cooling oasis, natural environments and waters in consideration of the air circulation. The connections should be continued on regional levels to planned urban expansion and to nearby municipalities to improve the urban climate, the micro- and macroclimate. The objective is to ensure the development of green and open spaces proactively and intercommunal.

Through interventions and “Design Thinking”-processes the inhabitants´ action areas – especially of people who are particularly affected by the heat like old, sick and invalid people or children – are used by activating them and integrating them into a network with local operators. Knowledge exchange and dialog processes during the whole project period help to identify obstacles concerning the implementation as well as conflicts and support the formation of a synergetic added value. Concluding, the foundation for a sustainable implementation through effectiveness indicators is prepared for a following “Cool-Demo”-project. Thereby, these research questions are considered: How can vegetation and innovative cooling technology be used most effectively in free spaces? Which small-scale climatic improvements (measurement results) are expected? Which methods are suitable to involve additional traffic infrastructure and energy? Which effects can be expected because of the measures?
