Heliotropic Skin
Building Skin
Washington, D.C. / Professor M. Simons / Spring 2009
Heliotropism is the diurnal motion of plant parts in response to the direction of the sun. Heliotropic fl owers track the sun’s motion across the sky from East to West. During the night, the flowers may assume a random orientation, while at dawn they turn again towards the East where the sun rises. Just like a heliotropic fl ower reacts to sun exposure the building photovoltaic panels moves from east to west durng the course of the day to harvest solar energy.
