Astana City Vision is the project for a new facility capable of accommodating up to 30,000 residents, workers and visitors. This project finds its right place in the young and lively capital of Kazakhstan, where urban development is carefully administered.
Conceived and designed with innovative criteria, this ambitious project has a dual purpose: first - to create a new intelligent model for a more efficient city, second - to find a solution to the climatic problem of Astana (which is considered to be the second coldest capital in the world with temperatures from -40 in winter to +40 in summer).
SENSE[able] City
Astana City Vision will be developed on an area of 1.75 sq km in the east part of Astana. The image we have of this new urban development is of “Senseable City”, capable of functioning as an organism able to react to impulses and to change its technological function according to the needs of the true protagonists of this project: the citizens.
The need to create a large dome (1500 m in diameter and a height of 350 meters) is the first step to create a microclimate that can respond to the climatic problem of Astana. This geodesic structure gives us the ability to control the climate inside in a surprising manner, and at the same time it limits the dissipation of energy resources.
The built area will be approx. 2 million sqm, while large spaces will be reserved for green areas and recreational facilities. The five entry gates will be connected with the parking areas for the petrol vehicles. These five access gates will be the starting point for the five major roads that will lead to the center of the structure where a 250 sqm skyscraper will stand high.
These roads are also connected to each other via a ring road that runs around the perimeter of the dome. They also act as dividers between the five areas where all the buildings will be positioned.
Air Cycle
The Dome will be realized using ETFE (Ethylene tetrafluoroethylene) air - filled cushions mounted on a light metal structure. The space between two protective layers will be used for technical purposes: polluted air extraction, snow melting, water recovery.
The structure of the Dome will be a dynamic skin, which will adapt to the external environment. When the climate is more gentle, some windows will be opened by the Central Management System and the air passage through the “skin” will be permitted. Otherwise, when the climate is far from optimal conditions, the windows will be kept closed and the internal environment will be protected from weather phenomena.
When the Dome is closed, air renewal will be provided by underground channels fed by wind cowls installed on the external perimeter. Air movement will be mainly wind-driven.
Water Cycle
The project will include an integrated water management system, where the rainwater/snow will be collected from the covering thanks to pipes installed into the gap between the skin layers and will be channeled to dedicated tanks.
Sun Cycle
The system will be set in order to maximize the use of solar gains in winter to save energy and maintain a warm environment under the Dome. During summer overheating will be avoided by dynamic solar shading devices included into the external skin layer. PV cells will be integrated in the external surface of the Dome in order to guarantee energy production from renewable sources.
Energy Cycle
The smart grid will collect information from all the devices, monitoring the external weather, changing the configuration of the protective skin and managing all energy uses inside the buildings. Under the Dome, only electrical vehicles will be admitted and charging stations will be provided in focal points.
