Tower of the Sun

Type
CTBUH collects data on two major types of tall structures: 'Buildings' and 'Telecommunications / Observation Towers.' A 'Building' is a structure where at least 50% of the height is occupied by usable floor area. A 'Telecommunications / Observation Tower' is a structure where less than 50% of the structure's height is occupied by usable floor area. Only 'Buildings' are eligible for the CTBUH 'Tallest Buildings' lists.

Function
A single-function tall building is defined as one where 85% or more of its usable floor area is dedicated to a single usage. Thus a building with 90% office floor area would be said to be an "office" building, irrespective of other minor functions it may also contain.

A mixed-use tall building contains two or more functions (or uses), where each of the functions occupy a significant proportion of the tower's total space. Support areas such as car parks and mechanical plant space do not constitute mixed-use functions. Functions are denoted on CTBUH "Tallest Building" lists in descending order, e.g., "hotel/office" indicates hotel function above office function.

residential / hotel / office

Height
Architectural
Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the architectural top of the building, including spires, but not including antennae, signage, flag poles or other functional-technical equipment. This measurement is the most widely utilized and is employed to define the Council on Tall Buildings and Urban Habitat (CTBUH) rankings of the "World's Tallest Buildings."

121.0 m / 397 ft

To Tip
Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest point of the building, irrespective of material or function of the highest element (i.e., including antennae, flagpoles, signage and other functional-technical equipment).
121.0 m / 397 ft
Occupied
Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest occupied floor within the building.
112.5 m / 369 ft
Floors Above Ground
The number of floors above ground should include the ground floor level and be the number of main floors above ground, including any significant mezzanine floors and major mechanical plant floors. Mechanical mezzanines should not be included if they have a significantly smaller floor area than the major floors below. Similarly, mechanical penthouses or plant rooms protruding above the general roof area should not be counted. Note: CTBUH floor counts may differ from published accounts, as it is common in some regions of the world for certain floor levels not to be included (e.g., the level 4, 14, 24, etc. in Hong Kong).

Floors Below Ground
The number of floors below ground should include all major floors located below the ground floor level.

Tower GFA
Tower GFA refers to the total gross floor area within the tower footprint, not including adjoining podiums, connected buildings or other towers within the development.

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.
