This project is close to Azadi square in Tehran which hosts as its centerpiece the Azadi tower, one the most important Iconic structures in Iran. It is an 8 storey commercial building with 5 storey underground parkade. The design challenge was to optimize the view and energy saving . at the same time. Therefore, a double skin façade with horizontal louvers on South elevation and vertical louvers on West elevation were created to lower thermal energy waste and increase the efficiency of using solar energy and view.
