The result by using the method is the INTEGRATED SITE REDEVELOPMENT CONCEPT, which opti- mizes investment needs, improving the chances of reactivating polluted properties.

RAISING AWARENESS ABOUT SOIL AND ENVIRONMENT IN
URBAN DESIGN EDUCATION: SUSTAINABLE LAND USE MA-
NAGEMENT AS A TOOL FOR URBAN DEVELOPMENT.
Although in today’s architectural and planning education the term of “sus-
tainability” plays a prominent role, the main attention is usually drawn to
technical knowledge while the basic issue of land consumption and land
use does only play a minor role. As part of the German government’s stra-
tegies for sustainable urban development, the REFINA program is targeting
to reduce land consumption for new settlement- and transport-related areas
IURPFXUUHQWO\WRKHFWDUHV WRDFUHV SHUGD\E\6HYH-
ral instruments and tools have been developed and applied as part of this
program in recent years to encounter this problem that is prevailing in many
urbanized areas world-wide, in areas of high as well as of low density.

the optirisk® team made an introduction to the project as well as con-

The bank refers to the river bank obviously. We would like to make Water
the key element to the site and the most attractive factor from the design.
Although there is a shopping mall to the west of our site, and a historic street
for commerce, there are no connections between both. So we want make
our site also for shopping to link with the two others. And each one will pos-
sess its own business direction.
Therefore, our idea „Shopping Bank“ make Water element and the main
function-Shopping together trying to build a good shopping atmosphere for
the whole city.

It rains a lot in this area, so we want to provide not only outdoor courts but
also indoor courts. We design a big roof with tensioned membrane struc-
ture and buildings with different functions under the roof, such as coffee
shop, restaurant, gym, Rock climbing. We also use the big roof to collect
rain water, to get a water stream in the site, combined with landscape. Peo-

and can be a landmark and historical marker of the site.

BLUE GATE
BLUE refers to the site identity which has a strong relationsship with water.
We try to illustrate the NEW BLUE concept by introduce activities which
closely related to water and also the revitalization of the water front area.
For instance, the original Sludge lagoon will be turned into a water perfor-
mance platform for public activities.
GATE concept can be interpreted by four phases:
the site ist a gate or a fringe place of urban to the nature
