In addition to facade, side lighting, the premises are insolated with the help of zenith windows. Thanks to the "scaly" structure of the roof, triangular zenith windows are formed, which somehow remind the silhouettes of soaring winged dragons.
Zenith lighting floods the premises with diffused light, which eliminates or minimizes glare, direct hit of Sun rays in the exposition zone, and also illuminates the central zones of the building with natural light.
Such lighting is a passive solar architecture techniques․ This trick of an efficient solution provides natural light and insolation, at the same time gives a non-standard perception to the interior. Zeniths, being, in fact, not a stereotypical source of light, create an alternative light and shadow, accepted in ordinary architecture and familiar to the human eye. This is new food for thought. The human eye, accustomed to perceiving standard lighting in residential and most other buildings, enters the world of new sources of light and shadows. During the day, "winged dragons" bring light, a warm and blue sky, and in the evening or at night with artificial lighting, i.e. a shadow and a starry sky overhead.
