Mansilla and Tunon Architects have designed a building for Madrid that will bring the city on the Green Map of the world. The building, which will function as an International Convention Center, will be cylindrical and its façade will be lined with solar panels. Apart from generating solar electricity, the interiors of the building will mostly be illuminated with daylight entering the building through the concave spheres, which will save the costs and energy of lighting.
The superstructure will also incorporate extensive rainwater harvesting systems to provide water for various uses. The 110 meters tall structure will house an auditorium for 5000 people, an event halls and exposition centers.

 
 
 
 
 
 
Solar platform in Sanlucar la Mayor
A new solar platform located in the municipality of Sanlucar la Mayor (Seville) was inaugurated last week, by president of the Regional Government of Andalusia, Manuel Chaves and the co-chairmen of Abengoa, Felipe and Javier Benjumea. 

The eleven MW plant is located 25 kilometers west of Seville. It took over four years to build the plant  (July 1, 2001 to December 31, 2005). In a much larger plan to build solar power in the region, this one is the first, but it’s not completed yet.
The plan is that by the year 2013, the 300 MW Sanlucar la Mayor Solar Platform will be completed. This requires an investment of 1.200 million euro. Then the plant will have the capacity to produce sufficient energy to let some 180.000 homes consume power from it.
The project will eventually prevent the emission of more than 600.000 tons of carbon dioxide into the atmosphere per year.
