Vira office building has been located in Yousefabad street, one of central district of Tehran, Iran. With total area of 10000 square meter, the project includes: 8 floors upper ground with office uses, ground floor and first basement floors consist of 3 separated commercial units and 6 parking floors below. According to the scale, the project is of great importance at the urban scale. The design of the project began with a critical question being asked by the client: How can we choose our approach to facade design without knowing the number of floors which could be vary between 5 to 10 floors? In addition, Municipal Facade Commission also had to approve the facade design. To achieve these purposes, we decided to design a basic module derived from the combination of an urban block and its associated green space, and subsequently multiply it in horizontal and vertical directions to achieve a combination which can be implemented in different structures with consideration asked by client. In addition, in the neighborhood of the project consisted of buildings of varying scales as well as generally rigid texture from the perspective of the materials. So our second challenge was to come up with a solution to create a rigid facade from an urban perspective on the one hand, and to maximize transparency on the exterior wall to benefit the interior on the other hand. To achieve this, the second skin of facade was designed as a combination of pre-fabricated vertical aluminum louvers attached to the curtain wall behind it to save energy, in addition to meeting the needs of the interior space. Furthermore, the combination of the Louvre with balconies and green space, as well as the light and shadow play on the office floors, will provide a visually pleasing experience for users.
