Cayan Tower wins CTBUH’s best tower in the Middle East

Cayan Tower in Dubai has won the Middle East and Africa category of the Council on Tall Buildings and Urban Habitat’s (CTBUH) best tall buildings in the world competition for 2014.

Winning buildings were selected from the USA, Australia, the Netherlands and the UAE.

One of the four will be named overall winner for the ‘Best Tall Building Worldwide’ accolade in November.

Cayan Tower, by SOM, is a 75-storey luxury apartment building, which features a striking helical shape, turning 90 degrees over the course of its 304m (997ft) height.

Each floor is identical in plan, but is set 1.2 degrees clockwise from the floor below, giving the tower a distinctive form.

The winner in the Americas was the Edith Green-Wendell Wyatt Federal Building in Portland, Oregon — an 18-storey, 512,474ft2 (47,610m2) office tower, completed in 1974, which recently underwent major renovation work by Cutler Anderson Architects, Sera Architects and Howard S. Wright Construction.

A distinctive shading façade has been added to the structure, transforming the building from a bunker-like, concrete-encased mass into a lightweight trellised volume which is much more energy-efficient.

One Central Park in Sydney by Jean Nouvel won the Asia and Australia category for its unusual technological features — hydroponics and heliostats — which are used to grow plants around the periphery of the building at all levels.

The shading saves cooling energy, while the heliostat directs sunlight for heating and lighting into or away from the building and the adjoining park when it is most needed.

In Europe it was the De Rotterdam by Rem Koolhaas’s firm OMA which won the title.

The largest building in the Netherlands features different light programs which lend dynamism and contribute to the humanisation of the monoliths.
