Humidity and room temperature will be controlled with assistance from the sun. Wind will be conveyed through a beer bottle instrument in the form of sound and will generate electricity.

Engineering
Visitors to the Atrium will breathe air purifi ed by a Virtual Jungle, look up at a Virtual Sky, bask in Virtual Sunlight and hear Virtual Wind & Rain mediated by rooftop light and audio collectors. Together these systems will transmit the essential and ever-changing conditions of the outside environment as well as provide a permanent physical artefact showcasing the myriad disciplines within the sphere of Engineering. A virtual skylight will act as a window to the world, showing both local sky conditions and any image from around the world.

Performance
The Virtrium is an example of Performance architecture, a space in constant flux, always evolving, subtly acting on the sense and

transforming the notions of the exterior world projected into the interior world. Performance architecture promotes a shift in emphasis from architecure as form to architecture as performance. Buildings themselves actively perform for, and respond to, the user. The user is both spectator of the performance and a participant in it.
