Oikos outdoor pavilion at Expo Zaragoza 2008

O-ikos means “the house” in Greek. Situated in the Ebro plaza, near the river aquarium the “Oikos”: Water and Energy Plaza” will showcase different sources of energy and devices to capture it such as solar panels, windmills, etc:

-The Sun. in a 6-metre diameter room with a dome-shaped roof the Sun is presented as the cause of meteorological phenomena, the day, night and our seasons.

-The wind. The visitor learns about the origins and characteristics of this meteorological phenomenon using three great tubes which, coming from the bottom with cold air, go through a module culminating in three chimneys. Surrounding the tubes there is a spinning hoop that represents a mill in motion.

-The house and water. The installation explains the importance of hydroelectric power using a mechanism composed of wind pump that extracts water from a well. This falls like rain on a dam, whose water then goes through a turbine to generate electricity. Finally it goes into an installation like a home where there visitor can see the many applications of water in the house.

-Climate control. The public goes through two “chambers”, one cold and the other hot, to point out the importance of insulation as a fundamental aspect of good climate control. If you want to know more on how you control climate change click at LINK

Lastly, in the final module, with the title “The possible house”, the application of all the alternative techniques viewed throughout the plaza is shown to reduce consumption of fossil fuels.

The above themes are very much in line with Aragon renewables potentialities. According to a GreenPeace report Aragon's solar potential would make it possible by 2050 to meet thirty-two times the projected total energy demand for this Community in 2050 (47.2TWh/year) and its wind potential would generate 5 times demand.

The pavilion itself has an exposition surface of 845 m2 and a budget of 3,4 million euros. Authors are Domingo Guinea, from CSIC as technical adviser and the german Roland Olbeter, who is an engineer by training and an artist (see his curious fontain in a previous post) who worked, among others, in the inauguration ceremony of the Olimpic Games of Barcelona 1992.
