About Tower of the Sun

Tower of the Sun is a mixed-use high-rise building suspended across the River Ishim in the heart of Astana. On the ground level, the building connects two large parks located on either side of the river via a publicly accessible pedestrian and bicycle bridge with a two-story high shopping mall positioned above it. Two monumental triangular shaped lobbies on either side of the circular opening's base are the main entry points for the luxury residential and multi-functional wings of the tower. On the rooftop a publicly accessible terrace offers unique views over the capital's skyline.

The ideas and symbolism of Kazakh culture and traditions are deeply intertwined in the concept of the project on every level, starting from the circular opening in the center of the building symbolizing the Sun, Peace and Unity – a symbol of core importance in Kazakh culture, to the triangular elements in the structure and interiors, which represent a powerful personal mascot that can be usually found in the traditional jewelry and clothing.

The project celebrates near net-zero energy requirements by using the power of water stream in the river underneath. It doesn't require a typical dam for creation of hydroelectric power, but introduces a narrower river cross section under the building to increase the stream speed and its power. Heat pump and smart building orientation which avoids overheating of the building from the south-western side during hot summer days maximizes the efficiency of the building.
