Aedas R&D, in close collaboration with Thornton Tomasetti and phaconsult, developed a concept design for the Taiwan Tower in Gateway Park of Taichung City in Taiwan. Like a pebble dropped into the sea, the tower’s shape derived from the form that emerges when a falling object hits the surface of water. The scheme’s plan takes the geometry of the new Gateway Park and forms a series of ripples that weave the tower into it surroundings, forming terraces, bridges and the main structure of the tower itself. Aedas R&D and Thornton Tomasetti jointly devised a parametric model to control the tower’s form, optimise floor space area and determine the number, size, pitch and distribution of the structural ribbons to fulfil architectural and engineering requirements. The tapered ribbons are of two types, with wider members acting as load bearing elements and thinner members helping stiffen the structure.
Great care has also been taken to reduce the tower’s energy footprint by making use of passive design strategies such as incorporating a central atrium and reducing slab depth to allow for natural light and air penetration, and offsetting the façade surface inwards to provide shading and at the same time minimise production costs. In addition to the above, the design suggests the use of wind and solar energy systems together with rainwater collection, ground source heat pumps and bio-fuels harvested from container grown algae.
The wide base of the 370 meters tall tower accommodates a spiralling museum as well as several levels of office space. At the top of the structure there is a restaurant and an observatory platform, which are viewed as the detached droplet of water suspended in the air before it falls back to earth. A wide basin is formed around the tower which orchestrates a dramatic reception for visitors approaching and compositionally allows for a smoother transition from the horizontal landscape to the high rise tower. Through a set of footbridges, the building is publicly permeable at ground level. This level accommodates the tower’s main lobby and the museum’s entrance to its own lobby one level below. The offices can be accessed by a separate set of footbridges which lead directly to the level above where a second lobby and café area are located. Alternatively a visitor can take spiralling paths to the basin’s bottom where supporting functions of the complex are housed.
