The tower’s form was inspired by Taiwan’s diamond industry, traditional origami, the Eiffel Tower, and the star, which is part of Taiwan’s flag. Combining all of these visual icons together into one building results in a large star-shaped, multi-faceted tower designed to rival Taiwan’s other famous skyscrapers. The eco tower would stand over 350 meters tall and includes offices for Taichung City Government, leisure and recreational spaces, retail and educational centers, and the new Museum of Taichung City Development.
As for sustainable strategies, the tower would include an integrated daylighting, shading and ventilation system to maintain the interior climate in an energy-efficient manner. Sunlight reaches in through the windows and bounces off floors, ceilings and walls to reach the interior of each volume, while automatic shades reduce heat gain when it gets too hot. The building’s atrium spaces allow hot air to rise up and out of the tip-top of the tower, where a vertical axis wind turbine takes advantage of the draft. The building also features high performance lighting with photosensors, radiant floor heating, rainwater collection, water-efficient fixtures and interior garden spaces.
OODA Architecture and OOIIO’s proposal received a Merit Award for the Taiwan Tower Conceptual Design International Competition, which weighed criteria at 50% for Architecture and 50% for Structure, Green Solutions and Office Portfolio.
