Rio’s Welcome Sign for the 2016 Olympics

RAFAA‘s ‘Solar City Tower,’ built atop the island of Cotonduba, will be the welcome symbol to the 2016 Olympic Games in Rio de Janeiro. It will be seen by the game visitors and participants as they arrive by air or water.

The tower, captures solar energy. It will supply energy for all of the Olympic city, as well as also for part of Rio: the structure pumps up water from the ocean to create what appears like a water fall stimulating turbines that produce energy during the night.

The tower possesses an amphitheater, an auditorium, a cafeteria and boutiques. Elevators lead to various observatories. The Olympic flame will also be hold within the tower.

A retractable platform is integrated for the practice of bungee jumping.

The following is the project description from the architect:

Concept

The aim of this project is to ask how the classic concept of a landmark can be reconsidered. It is less about an expressive, iconic architectural form; rather, it is a return to content and actual, real challenges for the imminent post-oil-era. This project represents a message of a society facing the future; thus, it is the representation of an inner attitude. Our project, standing in the tradition of “a building/city as a machine”, shall provide energy both to the city of Rio de Janeiro and its citizens while using natural resources. We hope to attain an international Olympic message with a political appeal. After hosting the United Nation’s Earth Summit in 1992, Rio de Janeiro will once again be the starting point for a global green movement and for a sustainable development of urban structures. It will perhaps even become a symbol for the first zero carbon footprint Olympic Games.

Approach

The project consists of a solar power plant that by day produces energy for the city respectively the Olympic village. Excessive energy will be pumped as seawater into a tower. By night, the water can be released again; with the help of turbines, it generates electricity for the night. The electricity produced can be used for the lighting of the tower or for the city. On special occasions, this “machine building” turns into an impressive wonder of nature: an urban waterfall, a symbol for the forces of nature. At the same time, it will be the representation of a collective awareness of the city towards its great surrounding landscape. Via an urban plaza located 60 meters over sea level you gain access to the building. Through the amphitheatre, you reach the entrance situated on the ground floor.

Organisation

Both entrance area and amphitheatre can serve as a place for social gatherings and events. The public spaces are also accessible from this point on. The cafeteria and the shop are situated beneath the waterfall and offer a breathtaking view. The public elevator takes the visitor to the observation decks and the urban balcony. The administration offices can be reached directly from the foyer. Its inner circulation is organised by an own entrance and the elevator. The semi-public spaces are located in the back area of the building; thus, they can be used separately. A retractable platform for bungee jumping is located on level +90.5. Long distance observation can be done from the observation deck on level +98.0. The urban balcony is situated at the top of the tower 105 meters above sea level. Here the visitor has a 360° view of the landscape and can experience the waterfall while walking over the glass sky walk.”
