Multi-objective context-adaptive natural lighting system

The main rationale and objective of the submitted research work is to create a quality lighting environment in the premises of deepened buildings and below-ground structures under screen effect of high-rise construction (high-rise buildings). It is noted, that in modern megapolises, a deficiency of vacant urban territories leads to the increased density of urban development with increased amount of high-rise construction and tendency to increase efficiency in the use of underground space. The natural lighting of premises in underground buildings and structures is the most efficient way, but it can be implemented only under use of roof lighting system in the form of roof monitors or skylights. In this case the levels of indoor natural lighting will be affected with serious screening effect of high-rise buildings in surrounding development. Such an situation is not regulated, or even considered by the contemporary building Codes and Regulations on natural lighting of interiors. The authors offered a new formula for a daylight factor calculation with roof lighting system in the described cases. The results of theoretical calculations and experimental studies showed very similar values. This proved the truth of the offered formula and elaborated method of calculation on the basis of an offered hypothesis. It prooves, that it is possible to use some factor and guide points in the daylight factors design under system of side natural lighting in the same design for a system of roof lighting.

The article describes main objects of sun-protection devices implementation in premises of industrial buildings. The study deals with the above mentioned elements, used for buildings with roof system of natural lighting, located in regions with hot and sunny climate. The use of sun-protection in such an outdoor conditions is widely known, but in most cases their implementation is connected with civil buildings. Different structures of roof lighting system are being considered in the article under two main criteria: a sun-protection quality and quantity of natural light, penetrated into the interiors. The conclusion was maid, that the best type of natural lights structures are monitors, equipped with canopies. These are the best in general, with respect not only to insolation limitation and natural
