The Center is arranged following the line of the ridge on the promontory. There are ten cases, all of different
dimensions, covering a total area of 7650 m². The largest is 28 meters high, approximately the size of a nine storey
building11. The orientation of structures this large is clearly of critical importance. North American students should
remember that the Center is in the Southern Hemisphere, and therefore conventions for orientation will be partially
reversed. The structure as a whole must be sited to gain the greatest possible advantage from the wind but the individual
cases must also be oriented to control sunlight and solar heat gain. The prevailing wind is from the East. The cases have
their backs turned to it, for reasons that shall be elaborated later.
