Technically acting as a sunscreen and weather barrier the curved façade is fully glazed and combines the curtain wall glazing with horizontal lamellas and vertical glass fins. The position and size of each of the façade elements are derived from a twisted frame system, which is related to the interior organisation of the building.
The concave front of the building displays different fluent forms when seen from varying distances and directs the visual field of the customers traveling on the spiraling escalators. Edge-lighting for the vertical glass fins spreads soft colours onto the façade by night. The lighting intensity and colour effects are digitally controlled and choreographed adding another layer of fluidity to the building’s skin.
The open and transparent glass façade is patterned with projecting horizontal, aluminum-faced lamellas and vertical glass fins that together form a swirling pattern. This pattern breaks up the scale of the building, which, from the outside has no legible floor heights as a result of the one-meter spacing between the horizontal lamellas. Ostensibly, the pattern of lamellas and fins acts as a sunscreen and weather barrier, but in reality the combination of the wish to make a ‘deep’ façade while preserving the internal floor space was behind the choice to apply a pattern to the outside frontage.
The pattern generates a strong urban effect, but has been modified on the basis of internal, functional demands. The vertical fins are for instance shallower and fewer towards the top of the building, where the restaurant is situated, allowing for higher transparency and better views towards the park opposite the building.
The fins are made of laminated, low-iron glass for extra clarity. A ‘frit’ (dot pattern) has been printed on both sides of the glass, so that the fins appear white by day. Thus they seem to be made of the same material as the horizontal lamellas, resulting in the visual illusion of a unified façade pattern. But from the inside, the glass fins offer uninterrupted views to the outside, as the dots are not apparent from the inside, just like net curtains. The production of the fins, which all have different dimensions, was facilitated by parametric design and production techniques.
The façade pattern wraps around the complete building, thus providing the closed rear facade with the same identity, but in a more simplified design.
At night, colored lighting replaces the optical effects produced by the depth embedded in the façade motif, with a fluid layer of changing hues and tones. The dots on the laminated glass fins pick up the colors distributed by LED-lights which are integrated at the bases of the fins. The minimized light fittings contribute to the luxurious appearance of the façade. The night-time appearance of the building is important in Taiwan, which has a tradition of late-night shopping and all-night markets.
The façade pattern was developed using animation software. A series of images was generated, which the client studied with the aid of a feng shui consultant. The final pattern was chosen because it represents a red phoenix.
