Coop Himmelblau’s project 'Expo .02 Forum Arteplage', a building consisting of a floor-area of 30.000 m² and a surrounding 85.900 m² park, was the winning contest-design for the pavilion 'Power and freedom - non verbal communication' for the Swiss National Exposition of 2002. 

The ‘non-verbal communication’ is established by the building itself, where on one hand, due to the full integration of movement and pressure sensors, the visitors communicate with the architecture, and on the other hand, due to sound and vision emitted by the architecture, the architecture communicates with its environment. 

Movement and pressure sensors record the visitor’s position in space to change in accordance to their position and movement the audiovisual aspect _ consequently it are the visitors who interactively change the architecture while changing their coordinates in space. 

Where space is constituted of an index according to xyz, colour’s coordinates rgb [ 0 – 255, 0 – 255, 0 – 255 ] are assigned to xyz. Changing position accordingly will affect the colour, establishing a colour-map / cartography – representing both physical and electronic space / position by colours.          

Reflecting on the water’s surface, the building’s dimensions and emissions change into an infinite illusionary play. 

At the same time, the visual effect contributed to the visitor’s position, reacts on environing sonorities causing the constant change of colour-intensity. 

Walls are fully equipped with microphones to register the sounds of the environment, being the sonorities originating from internal and external activities. Inside the building, where apart from the sophisticated manner in which speakers and sound equipment are integrated in the building’s construction, sound is treated and modified permanently by a team of sound-engineers and the operating technology. Music performances take place constantly, combining their music with the building’s emissions, constituting a constant sonic and visual effect. 

Additionally, the pavilion not only radically integrates the building’s sonic aspect on the level of acoustics, but aims to affect the perceptive aspect of music, concei...
