Realising Alfa retail park’s expansion project, within which a new store, cafe and also theatres with several new screens were constructed. The Cinamonmovie theatre was opened on 7 November, 2008. It has eight theatres with a total number of 1360 seats for viewers. Our task was to construct an automatic heating, cooling and lighting control system, or building control system, for this theatre.The building control system is very important for uninterrupted theatre work, which is why it is very important to this object. In those days, the film projection room was not digitised, so the necessary cooling equipment had to be constantly provided.
