The Indianapolis downtown library features a unique design for the facades. The façade fits between two independent buildings. To create a transparent façade using cables, a novel counter weight system was adopted. Horizontal cables are anchored to one building and run over a pulley to turn 90 degrees and a large hanging cast iron disc creates a constant cable tension. As the wind pressure hits the façade, the disc can move vertically. The system utilizes the AES, TC + CCG Systems. Corner clamped glass adds to the transparency.
