Influence of the Shape and Proportions of Window Openings and the Presence of External Window Wall Structures on the Luminous and Insolation Environment in the Premises

The article deals with issues related to ensuring the required parameters of the luminous environment in the premises of civil buildings with a lateral system of daylighting in them while simultaneously ensuring the necessary duration of insolation in these premises. It is noted that in modern architectural and construction practice, these requirements can be met, in particular, through the use of various shapes and proportions of window openings, as well as through the use of window wall structures of various types. On the basis of the conducted research, it was concluded that this approach is promising, since it fully meets modern requirements for the creation of energy-efficient buildings based on passive (natural) methods that ensure a normal microclimate of the internal environment in the premises solely due to specific architectural and structural design techniques.
