Green and sustainable design
Vienna has several sustainability features including solar panels, water tanks, efficient lighting and double glazed windows.
There are six large solar panels on the roof of the building attached to a large battery to help collect and power the building during the day as well as throughout the night.
The roof also has several drainage solutions to collect water which are stored in large water tanks underground. This grey water is reused in watering plants and in toilets.
Vienna is powered entirely by LED lights - most of which are controlled by motion sensors or ambient light sensors.
All of the windows and glass panels used in the building are double glazed to help reduce the cost of heating and cooling the building
