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.
