Conceived and designed with innovative criteria in terms of architecture, engineering, environmental sustainability and technology, this ambitious project has the dual purpose in one hand of tracking the guideline for a more efficient city, and on the other to find a solution to the climatic problem of Astana (which is considered to be the coldest capital in the world with temperatures from -40 in winter to +40 in summer). This project has followed the requirements of the client who has placed at the center of its program three key points : - Astana City Vision as a new intelligent model of urban and social development; - Astana City Vision as an opportunity for industrial development in the high-tech sector; - Astana City Vision as a sustainable city. Astana City Vision leads the way to the idea of Smart city becoming efficient and functional, becoming the concrete response to the unregulated growth of cities dissipating resources and energy.
