During 2019, our member Nemanja Delja, collaborated with the Program Archive of Radio-Television of Serbia. Using the photographs from this archive, Nemanja designed the decorative foils for the windows of the Restoration and Conservation Center and the Center for Digitizing the Archival Materials of Radio-Television of Serbia, adding new visual elements to the building and playing with the new visual dynamic of its facade. The foils do not only serve as decoration, but also, by selectively letting through the light and the heat, they increase the energy efficiency of the building. Due to the fact that the photographs are exhibited in the public space, they permanently communicate with the people who are passing by, and further promote this photographic cultural heritage.
