scenario to transfer competition results into an urban development mission statement that encompasses UHI-relevant measures (Fig. 9.9 ).
To spark the discussion objectives were defi ned for the “competition inviting
urban development ideas for Nordbahnstraße – Innstraße”. Additional competition
documentation defi ned quality objectives along with “hard” project requirements,
such as gross fl oor area, the mix of residential areas/offi ces/retail/commerce in percent, as well as social infrastructure. Following spatial analyses and information
campaigns for the public the “general conditions and objectives for the competition
inviting urban development ideas” (MA 21A 2011 ) were drawn up. It was during
this early planning stage that the fi rst UHI-relevant goals and criteria were drafted.
A number of solutions mentioned in the collection of measures were strategically
positioned at this point already. The objectives for the urban development competition reveal modalities of how these measures may have a bearing on subsequent
implementation stages. One of the requirements, for instance, was to create a system of green and open spaces with a high quality of use for everybody, another was
to link the new city quarter with the surrounding main green and open spaces. Other
requirements included minimising the degree of soil sealing, as well as considering
and integrating urban climate aspects (sun/shade/wind/humidity) in competition
submissions across the board (MA 21A 2011 ).
