Watch This!

This amazing piece of ecological architecture is located in Dezhou in the Shangdong Province in the northwest China.

The 75,000 square meter structure is a multi-use building, it has exhibition centers, scientific research facilities, meeting & training facilities and a hotel.

The coolest part of this amazing structure is that it operates 100% with solar energy, all of which is created by the building! And you have to admit, it looks pretty cool.

This building was created with the good intentions of using the famous "renewable sources" of energy in order to replace the need and use of the fossil fuels. It is the biggest solar powered building in China, and in the world. 

This helps to the environment in a very poorly amount because it's only one building, but it's an amazing start, and an excellent example for others to get in the same track and show the world it's possible to get rid of the fossil fuels.

Map of the Wall

The great wall of China was officially started named as the Great Wall Of China in 200BC. But, it was finished as we know it now (this is also due to reparations of the wall, expansions & fortifications) in the 17th Century! This means it took more than a millennium to finish the Wall!

The 828meters of this tower were desinged by the same person who desing the Willis tower, and the One World Trade Center. It is supposed to represent cultural and historical elements of the region.

The Burj Khalifa's water system supplies an average of 946,000litres of water per day through 100km of pipes. An additional 213km of piping serves the fire emergency system, and 34km supplies chilled water for the air conditioning system. The tower's cooling is equivalent to that provided by 13,000tons of melting ice in one day! To wash the 24,348 windows, totaling 120,000 m² of glass a horizontal track has been installed on the exterior of Burj Khalifa at levels 40, 73, and 109. Each track holds a 1,500kg bucket machine which moves horizontally and then vertically using heavy cables.

 This building has an enourmous variety of thinghs (as shown in the image at the right). It includes from the Armani hotel & suites, to the skyviews in three diffrent heights of the tower and to the base jumping of the tower.
