Radiating from the center of the complex is an Earth Gallery to one side and a Sun Gallery to the other. The Earth Gallery is a fascinating 262 foot-long embedded earth hall with walls made from 1/2 inch corrugated sheets that absorb the sun’s heat and transfers it to the rest of the building. The turning hall has mirrors at the corners to reflect daylight down its passages. The Sun Gallery and Chimney Hall provide the bulk of solar heating on colder days, and the entire system is controlled by simply opening and closing doors and internal windows.
The project’s water systems are also designed with sustainable principles in mind. Waste water is filtered on-site with a plant-based water purifying system and then used to irrigate orange and olive trees. Reclaimed materials are common throughout the building — blocks discarded from the copper operation and sunk into the sea make up the Sun Gallery and bricks from the crumbling buildings are used extensively, as are clay tiles and even the landscape itself.
