green glass bricks, photovoltaic system, LEDs
Within the cube, completely closed except at the top, a photovoltaic system is installed. During the day the cube glows in countless shades of pale, light and bright green depending on the sun’s angle of entry and on the movement of clouds. If the sun hits the cube head-on early in the morning, it is golden. In addition, shadows of clouds transform the cube into various triangular shapes of light and darkness.
The photovoltaic system takes up and stores solar energy which is used to light up the LEDs – and the cube – at night.
