My main idea is to design and build a community leisure centre that powers it self on exercise and kinetic facades on the building. The facade ideas are from Ned Kahns work and consist of 10cm square photovoltaic panels. The other facade idea uses movement in the same way a wind turbine does with small rotating pieces of wood, they are moved by running water harvested form the roof and the natural force of the wind. Water will be saved where possible in the builidng by using waterless urinals and reusing rainwater throught the building. If possible black water will be used if it can be cleaned and reused at a reasonable cost.
