Up-Draft - Jan Petrš Architecture

Up-Draft

The main task was to design a solar updraft tower (SUT) in Sahara desert. SUT is a renewable-energy power plant for a generating of electricity from low temperature solar heat. Sunshine heats the air beneath a very wide greenhouse-like roofed collector structure around the central base of a very high chimney tower. The resulting convection causes a hot air flow in the tower by the chimney effect. This airflow drives wind turbines placed in the chimney stream or around the chimney base to produce electricity. For the tower it is very important to be placed in locations with high temperature. Sahara desert is suitable for it. Otherwise there is an insufficient infrastructure for such a big building. Due to it, we developed a script for a searching of optimal location. Due the poor infrastructure concept count with an autonomous building process by robotic 3D sand printers. The shape of the tower is based on swarm behaviour and local conditions, the tower consists of several pipes where the air is flowing and in which are turbines for generating of the energy, each robot builds one pipe.
