Facade covering, Spanish Expo-Pavilion, Zaragoza, Spain

This example of ecological and sustainable architecture was really an outstanding piece amongst the many pavilions and buildings built specifically for the Expo. So outstanding that there were rumours of 4-5 hour-long waits to get inside. The exterior col

umns, which look almost like reeds or bamboo shoots, are made of terra cotta (clay) with a metallic core that when in contact with water create air currents and a microclimate that has a cooling effect on the building. This is an important design feature

when you're facing 40ºC heat. The roof is also equipped with solar heat and rainwater collectors.
