The client was Tehran Municipality who intended to build a complex for book exhibition, library and a theater. The Architect was Mr. Tehranchi from Haste Tarahi office. I was acting as the facade designer and later project manager for a year. we installed more than 10,000 m2 glass panels. We used 3 layer sunergy glass panels to control the incoming light and reducing U.V and infrared. We also designed the roofing glass which you can walk on for maintenance while keeping all energy factors in mind.
