Assessment of overcast sky daylight conditions in the premises of engineering operations considering two types of skylights

摘要

Lighting in manufacturing plants is an integral part of a working environment and all industrial activities. Therefore, it is necessary to consider several aspects of these activities when designing and using industrial lighting. To comply with lighting requirements, hygienic and technical regulations, which set visual and lighting requirements to achieve safe and proper lighting conditions for all activities in industry buildings, need to be taken into account. The aim of this study is to evaluate the existing lighting of industrial premises through measurements. The measurements were carried out in two halls with the same floor plan and with the different types of side illumination and skylights. The measured values then served as input data into the RADIANCE simulation program, which was used to calculate daylighting and, subsequently, to evaluate visual conditions and illuminance levels in work spaces. Similar average levels of daylighting were observed in both halls. The hall with smaller lighting vertical openings and the arched shape of the skylight, was better lit by daylight. The daylighting evaluation of measurements results higher level of minimum and maximum daylight factor as well as illuminance uniformity.
