What dangers and opportunities exist in the heights where no one can reach? In a geography where rising masses swallow the cities unconsciously, can one tower create a significance? The suggested Antalya Expo Tower, questions these possibilities.
In Turkey, fertile lands are being destroyed because of rapid population growth and unplanned urbanisation. For this reason, the tower aims to protect and support its own context by taking referance from the agricultural area as well as the Expo zone that surrounds it rather than being an urban generator. Thus, the tower has taken referance from a larger context and has been designed in a relevant scale. It also uses the 360 degrees of panaromic view of the point that it is designed on.
The Expo Tower contains a water storage tank that is placed to create a 0,48 MPa water pressure on its ground level that will be used for water procurement and storage functions for the Expo area. It also contains a tank for water purification that uses inverse-osmosis method. It gets all the energy it need for its pumps, LED lights and all other electronic and mechanical systems from PV panels that are adjustable in horizontal axis according to the solar angle. With this property and its ability to get irrigation water from the dew, underground water and gray water, the tower aims to be a self-sufficient structure.
Different measurement devices like anemometer, higrometer and actinograph are suggested to be placed on the top pole of the tower at different heights. Also, LED lights that are going to be placed on the terrace at 170 meters level will warn the people, farmers and sailors by changing colors according to the data it gets from the top pole. Thus, the tower itself will function as a meteorological observation station.
Considering the feasibility of the project, it was based on modularity. Beside the service core, the pillars will also be built modularly by using steel profiles and precast fiber-concrete panels. The tower owes its ability to carry a large terrace on its top and to protect its transparency as it gets higher to its original form. Also, a system of concrete raft foundation at the projection of the tower mass on the ground and piles underneath it, is proposed.
Antalya shows the characteristic properties of mediterrenean climate. The air is quite humid and the earth is arid. Considering this property, the tower gets water from the moisture in the air by using "dew harvesting" tecnique that was created by inspiration from namib beettle livin in Namib desert. The humid air gets filtered by microfiber meshes and leaves its dew on them. The dew is then transferred to the water storage tank by vertical pipes and horizontal copper wires. The water in the tank is used for agricultural irrigation. With this method, the moisture in the air is transferred to the arid earth by totally passive methods.
