The Al Bahr Towers have a dynamic, translucent facade that runs off power generated by photovoltaic panels and that reacts to sunlight. The facade aims to reduce interior temperature from sunlight by around 50%. The mobile facade consists, per building, of 2,000 umbrella-like elements that can be opened and closed.

The skyscraper takes the name The Bow from the Bow River that runs nearby. At 236 meters it's the tallest building in Calgary and the third-tallest in Canada. Innovative use of steel and glass makes the building 30% lighter than other buildings of its size.

The slanting, exposed-concrete columns at the base catch the eye, as does an atrium that joins the skyscraper to its 132-meter-tall sister tower. At 213 meters, House on Mosfilmovskaya 1 is one of the 10 tallest buildings in Russia.

Zhengzhou Greenland Plaza is the tallest building in the central Chinese city of Zhengzhou. The building houses office space and a 435-room hotel. The facade's specially manufactured aluminum screen provides protection from the sun and at the same time reflects indirect daylight into the interior. The tower also includes a heliostat at the top that directs sunlight down into the hotel's atrium.

German building data company Emporis issues list of best new skyscrapers
Winner known as "Marilyn Monroe" due to curvy design
Al Bahr Towers in Abu Dhabi has outer skin that rotates in response to the sun's position
No U.S. buildings made the top 10 list this year
(CNN) -- A pair of buildings colloquially known as "Marilyn Monroe" has won the prize for best new skyscraper completed in 2012.
The curvy, twisting buildings, officially known as Absolute World Towers, and located in Mississauga, Ontario, were designed by Beijing-based MAD architects and Toronto-based Burka Architects.
"The way the two structures twist organically by up to eight degrees per floor is not just a superb technical achievement, but also a refreshing change to the set forms of high-rise routine," said an international panel of expert judges when explaining their decision.
The prize, given by building data company Emporis of Hamburg, Germany, "rewards skyscrapers for excellence in their aesthetic and functional design," the company said.
It's the thirteenth time the prize has been awarded.

Other entries in the top 10 include buildings from Doha (Qatar), Moscow, Guangzhou (China) and Milan (Italy).
The second place Al Bahr Towers in Abu Dhabi, designed by Aedas Architects, has an outer skin that rotates in response to the sun's position, leading to cooler temperatures inside the buildings.
