Purpose. The analyze of the possibility for natural light wind in the new modern construction projects and in the existing buildings. Conclusion. The operating norms of the light environment were analyzed. The constructive solutions of light apertures for the penetration of natural light to workplaces with regard to the ecoclimatic lighting conditions on the example of the city of Dnipro are studied. The analysis of the existing modern systems of artificial and combined lighting was carried out, the influence of lighting by levels and sources on the state of human health, efficiency and safety was considered.
