Kaohsiung Stadium in Kaohsiung, Taiwan

With its open design, the Kaohsiung Stadium also known as the World Game Main Stadium, not only mark an advance in construction techniques but differs from classic stadiums traditionally closed. This stadium designed by Japanese architect, Toyo Ito, uses the sustainability concept which make it a green building.

Photovoltaic cells as the roof of the stadium

The stadium has 8844 solar panels along the 14,000 m2 of surface. This cover can supply up to 1.14GWh of electricity annually, reducing the annual output of 660 tons of carbon dioxide and connected to the energy matrix could feed up to 80% of the surrounding area when not in use. The stadium has an average of 3,300 lux of illumination.

A ceiling sensor chips keep track of all consumption and distribution of electricity and send information to a small power station inside the stadium. Other sensors keep track of the solar farm to detect broken or damaged panels.

Internal structure of the stadium roof

With thousands of solar panels covering its semi-shaped structure, which resembles a dragon or snake, is the first stage that runs completely with this energy while the largest photovoltaic system in Taiwan to date.

The builders had to create new materials during construction and fix the solar panels so that they serve to protect the spectators, for not only provide energy but are directly the roof of the stadium. These new roofing materials combined with the solar panels were studied by computer to determine the impact of earthquakes and typhoons could have on them. Computer models also helped to determine the correct orientation of the roof to protect spectators from the tropical sun of Kaohsiung.

An aerial view of the stadium

Opposite the entrance is a fountain built in a half moon shaped, for the wind to pass through on their way to the stadium. This creates a natural ventilation of the

stadium.

Besides, all raw materials used in the main stadium is 100% recyclable and Taiwanese manufacturing.

The concrete interior of the stadium

The roof also collects rainwater for use inside the stadium. A system of pipes carrying water to underground storage tanks, where it is sterilized and then returned to be used for grass or source.
