Fubon Xinyi A25

The Fubon Xinyi A25 () is an under-construction skyscraper located in Xinyi Special District, Xinyi District, Taipei, Taiwan. It will be the sixth-tallest building in Taiwan and the fourth-tallest in Xinyi Special District. Designed by Renzo Piano, the height of building is 265.6 m, the floor area is 132,362.85m2, and it comprises 52 floors above ground, as well as 4 basement levels. It will be completed at the end of 2021 and the headquarter of Fubon Financial Holding Co..
Design.
With almost 100,000m2 above ground and 4 levels of basement, the Fubon project consists of three buildings within a landscaped, shaded urban realm. The central 54-story, 265m high tower of 92,000m2 (GFA) will accommodate high-end offices and at its rooftop a garden events space with views of Taipei. To the east of the Tower, the 3-floor high Fubon Museum includes over 2,000m2 of contemporary and modern art galleries. To the north of the Tower, lies the Pavilion of 1,970m2, accommodating retail and services for the entire complex. More than 150 trees will be planted in the landscaped garden, offering the public a shaded environment in a sub-tropical climate. North of the site, a park will be created to give the surrounding residential area a neighborhood park.
The slender tower has a rational floor plate size of 1650m2 and a good floor efficiency of up to 73.5%. The floor plate with floor to floor heights of 4.2m allows good layouts for the offices, with a depth ratio that ensures quality daylighting levels in the office work place.
The square shape with cut-back notch corners employs an efficient steel structure. Perimeter bracing combined with a secondary moment frame structure provides a robust and efficient structural system to resist lateral seismic and typhoon wind loads.
The façades will be made of low-iron extra white glass with a neutral colored solar control coating to give the tower a crystalline appearance. The façade cavity system will include cavity blinds and will ensure good solar control, daylight levels and thermal comfort and performance. The project is committed to obtain the Taiwanese Green Building Certification (EEWH), with the objective of achieving the Gold level.
