Wind energy is translated into the unlikely rotation of a mechanical platform embedded in the courtyard of Munich's building department administrative building. A turbine placed atop the building tower captures wind energy that is used to power a turntable of landscape, lying within the protected confines of the building's walls. A connection, however abstract and perhaps invisible, is made between the force of wind and the slow rotation of the platform. The effect of this unlikely relationship is a surreal and unprecedented landscape condition: A PORTION OF A COMMON COURTYARD DESIGN BECOMES A MOVING IMAGE OF CONSTRUCTED NATURE, WHERE TREES, PAVING, LIGHTING, AND BENCHES ALIKE REVOLVE AS IF ON DISPLAY.
The rotating ring of landscape in Acconci Studio's Courtyard In The Wind rests flush with the surrounding lawn and paved courtyard. The turntable contains all the typical landscape components, creating an illusion of continuity between the trees, grass, and paved areas of the formal courtyard, if only for one moment in its revolu-

Courtyard in the Wind, Buildings Department Administration Building,
Munich, Germany tions. As the ring rotates, this composition revolves in and out of alignment, carrying trees and visitors alike. Building occupants around the courtyard are presented with a view of a seemingly normal composition performing a mechanical dance. The turntable is designed to act as a massive mobile planter. It rotates on a track contained in a sub-surface circular chamber that houses a set of motors and series of wheels. The wind turbine, mounted on the tower, generates the energy used by the motors to rotate the wheels. With a rotation freguency of two revolutions per hour, the landscape moves slowly, at about 2cm/sec. At this speed the movement is barely visually perceptible and can be slightly felt by visitors walking across the turntable.
WHILE NOT A DIRECT "TRANSLATION" OF WIND INTENSITY, NOR A MEASUREMENT OF ITS DIRECTIONALITY, THE MANIFESTATION OF THE WIND ON THE COURTYARD LANDSCAPE GIVES FORM AND EXPERIENCE TO THE INTANGIBLE FORCE OF WIND.

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
