Sustainability and energy efficiency have gained increasing importance in recent years in Europe and worldwide. Driven by the economic crisis, the need to reduce costs on the one hand, and to increase energy autonomy on the one hand, as well as the increasing awareness of climate change, have made improving the energy efficiency of buildings a central strategy in future of the European Union. 

Energy consumption by EU buildings has been increasing in recent years and now accounts for about 40% of their total consumption, leading to high economic and environmental costs with Very high CO2 emissions, which, as is widely known, significantly contribute to the increase in weather problems that occur. 

In order to reduce the energy consumed in European buildings and thus the resulting economic and environmental problems, in 2010, the EU published Energy Performance Directives requiring all buildings constructed from 1 January 2021 onwards. Have an energy balance close to zero, through buildings erected with materials that allow for greater efficiency in this field, and by greater use of renewable energy.


For years, biblical scholars have been debating whether the Tower of Babel really existed. 

A new study of a stone found in ancient Babylon (present-day Iraq) about a century ago may prove the existence of the Tower of Babel. According to the University of London professor Andrew George, on the object is a drawing of a tower with steps and a person holding a spear and wearing a cone hat. “Below is a text that says ‘ziggurat’ (pyramid-shaped monument)), or ‘Temple of Babylon,’” he says in an interview with Smithsonian. 

The 6th century BC stone, for the expert, shows the first real image of the Tower of Babel, highlighting the seven layers of the structure, and identifies a man behind its construction, Emperor Nebuchadnezzar II. 

The object also reveals details of the structure’s construction, and more importantly, how Nebuchadnezzar built it. The story written in the rock is like the one in the Bible, which increases the researcher’s suspicions. 

Nebuchadnezzar II is considered by many to be the greatest emperor of Babylon. He ruled between 604 BC and 562 BC and was responsible for the construction of canals, aqueducts, and reservoirs throughout the empire.



The Babel Tower is one of the most intriguing tales in human history, supposedly built by men who wanted to make the tower so high to reach the Gods. However, the Gods did not like the pride of men and overthrew it. Beyond this mythical explanation, the tale would clarify why so many languages exist in the world. 

The signs of Babel Tower begin in the bible, especially in the Old Testament book of Genesis. According to him, the tower would have been built by Noah’s descendants at a time when the whole world spoke only one language. Supposedly, the location of the Tower of Babel would be between the Tigris and Euphrates rivers in Mesopotamia. 

The pride of men in engaging in the endeavor to reach the world of gods would have caused the wrath of God, which, in the form of punishment, would have created a high wind to topple the tower and scattered people upon the earth with different languages, to confuse them. For this reason, myth is understood today as an attempt by ancestors to explain the existence of so many languages in the world.




Theme: the new Babel Tower



The purpose of this exercise is to recreate what would be the Babel Tower today. A tower that symbolizes the unity of peoples, regardless of their color, race or religion. A tower that values the human race as one. Above all a tower that breaks with the current building model. An environmentally friendly tower. 


There is no specific program for this tower. 

More than its function, we want to deepen new, environmentally friendly building systems for a new model of sustainable cities. 

It is essential that the new Babel Tower represents a break with the past and present with regard to building systems. We are looking for a building, Carbon 0, a building that marks a change of mind and that serves humanity and not the economic interests of capitalist societies.
