Introduction Autobiography of Taipei 101 Initiation Construction
Characteristics of the Architecture Shopping Center: Taipei 101 Mall Office Floors Observatories

Designed by CYLEE & Partners Architects / Planners, TAIPEI 101 is the first in the world to adopt multi-link architecture. Mr. Lee and his partner Mr. Wang fused oriental elements with modern architectural methods, portraying a building full of Eastern symbols and characteristics.

The exterior
From the 27th to the 90th floor totally 64 floors, taking every 8 floors into a node, or a link, with total of 8 nodes, and each node with the appearance of an inverted trapezoid box shape, the architect blended the idea of the ancient Chinese tripod. Each node with its sides opening wider upwards resembles a blooming flower, symbolizes the Chinese saying of richness and prosperity. The dome ceiling of the skirt structure is in the shape of “Ru-Yi”, matching the theme of “ Financial Center ”. The exterior from the 24th to the 27th are decorated with motifs of ancient coins.

The structure

Most skyscraper designs in the past had main supporting columns on the outside of the building exteriors, forming cone-shape structures. The best example was the New York World Trade Center Twin Towers . TAIPEI 101 design uses 8 main supporting column structures inside the building, thus enables non-stop glass panel installations to from the bottom to top of the building, making TAIPEI 101 a gigantic glass enclosure. The 7 degree inverted slope of each node allows each floor to have non-obstructed view of the surrounding environment. With every 8 floors as a module, a specific elastic frame is designed to support the weight of 8 floors as well as to counter the impacts of earthquakes and typhoons.

Unlike traditional skyscraper designs, the inverted 7 degree design creates one platform above every 8-floor node which can be used for suspending window-washing apparatus es and emergency evacuation purposes. The bottom floor in each node has the least floor area among the 8 floors, and is used for housing equipments and machineries. This equipment/machinery floor requires ventilation, yet the use of metal blinds would damage the harmony of appearance on the all glass exterior. The solution is to use the larger floor area of the eighth floor of the node below to form inverted eaves, blocking the metal blinds from the views of on-lookers.

Mass damper equivalent to the weights of 20,000 elementary students

To deal with the vibrations caused by earthquakes and typhoons, TAIPEI 101 employees the world's largest tuned mass damper. A 660-metric-ton steel ball is suspended from the 92nd floor to the height of 88th floor inside the building structure. It behaves as a gigantic clock pendulum, and counters the vibrations of the building during strong quakes and typhoon winds. Currently it is part of the attractions on the 88th floor observation deck, and will be part of the decor in the observation deck restaurant.

The metal structures at four corners of each evacuation platform serves as lightening poles for side-impacting lightening, and also house lights (flashing red) for aviation alerts and (flashing white) decorations.

To reduce the number of elevators and make vertical transportation faster, TAIPEI 101 uses double-deck elevators. During peak commuting hours the ascending passengers are separated to board the elevators at 1st floor for odd number floors and at 2nd floor for even number floors. Similar to other skyscrapers, TAIPEI 101 has transit floors at 35th/36th and 59th/60th. For instance, to go to floors from 59th to 84th need to take the elevator at 1st/2nd to 35th/36th and make the transit at 59th/60th. To go to floors from 35th to 58th, the transit needs to be made at 35th/36th. By reducing the number of the floor stops it saves passengers' vertical commuting time.

All floors from 9th to 84th except the equipment/machinery and the transit floors are office spaces for rent. Despite the tall 4.2 meter ceilings, measures such as ice storage air conditioners and heat-insulating double-layer glass panels for the exterior are used to conserve air-conditioning energy. To ensure the stable power supply, Taiwan Power Company supplies necessary electricity from two nearly-by transformer stations. Emergency generators in TAIPEI 101 can supply 70% of necessary power and reserves the remaining 30% for air conditioning during emergencies. Two large fire evacuation rooms are present on each equipment/machinery floor.

TAIPEI 101 has two observation decks. Taking the world's fastest elevator (max. speed 1010 meters per minute) from the 5th floor to the indoor observation deck on the 89th takes 39 seconds (the 90th is the equipment/machinery floor, block from the view by the top-most inverted eaves). The outdoor observation deck on the 91st can be accessed via stairs from the 89th. The reason for observation deck entrance on the 5th floor of the shopping arcade is not to obstruct the office floors.

The floor space becomes smaller from the 91st floor and up. The exterior measurements of 91st, 92nd, 93rd, and 94th are equivalent to 1/2 of that of the 89th, and then it gradually increases from the 95th to the 100th. Floors 91st to 100th are used to house civilian and government communication equipments for its tallest height in Taipei City . The 101st floor is the VIP conference room, with its floor height at 438 meters from the ground, and its ceiling height is 10 meters, making the tallest building ceiling height of 448 meters. It holds the record of the tallest building space with human activities in year 2005.

There are still 60 meters from the top ceiling of 101 to the tip of the entire building, and that includes the semi-spherical decorative structure plus the base of the pole tower at 7 meters, and the 53-meter pole tower, totally 60 meters. The cross section of the pole tower is a square with 4-meter sides. The entire building with total height of 508 meters currently holds the record as the world's tallest building.
