“…The calculated electricity consumption per square meter of the classroom area and the energy savings potential are presented in Table 1. The results show that the energy saving potential through the implementation of on/off control reached about 28% and this value is similar to the results obtained by Lo Verso and Pellegrino [17]. However, it should be noted that this value is obtainable for a classroom oriented to the south-east.…”

“…Various control technologies are developed [16] and their implementation influences the energy saving potential. Lo Verso and Pellegrino [17] have estimated the energy savings considering four strategies of daylight-dependent controls, included in the standard EN 15193-1:2017 [18], as well as occupancy control. They considered classrooms with different daylight availability, window orientation and shading system, located in sites at different latitudes and in different climate conditions.…”

In this paper, daylight availability depending on building orientation in a typical educational classroom was investigated. Measurements of daylight illuminance distributions in the room depth for different illuminance outside the building allowed to determine the conditions when the luminaires in a classroom could be turned off, turned on, or dimmed. The outdoor daylight illuminance on the south-east and north façade of the building was recorded and the numbers of hours per year of university activity during which the lighting had to be switched on (up to 100% or brightened) were determined. Based on these numbers and luminaires powers the electricity consumption for lighting was estimated. It was proven that by using dimming control depending on daylight distribution in a room, comparable energy savings could be achieved for different building orientations. These savings of over 30% were greater than through the implementation of on/off control which, for a south-east oriented classroom reached about 28% and for a north-oriented one they were two times lower. Economic analysis showed payback time for dimming control around two years, which was longer than for on/off control. The electricity consumption estimated experimentally was also compared with the lighting energy numerical indicator (LENI) calculated according the standard EN 15193 1: 2017.

“…The efficacy of energy saving measures related to artificial lighting in buildings greatly depends on the use of lighting control systems linked to daylight and occupancy. Regarding this topic, it is worth noting the study of Loverso et al [7] who carried out a comparative analysis between the four typologies of lighting control systems defined by the Standard EN 15193-1:20017 [8] for a great number of buildings in public and scholastic sectors, in various European locations, showing the great influence of the lighting control system used on saving energy.…”

Daylight plays a significant role in achieving energy saving and comfort in buildings. It is in accordance with the human circadian rhythms and allows the best visual conditions in work environments and residential buildings. Recently, numerous researchers have focused their attention on the performance of technological devices able to increase natural light availability in interior areas of buildings. Among them, light shelves are commonly used with the aim of improving the depth of daylight penetration, trying to reduce the nonuniform diffusion of light entering from vertical windows. In this paper, the authors propose six different configurations of an internalexternal light shelf and analyse their performance using the experimental scale model approach under real sky. Although the method is not very accurate as deduced from literature on this topic, the authors still demonstrate its usefulness in examining different geometric configurations of light shelves. In fact, even if the results highlight inaccuracies in the method used, which are accentuated under direct sun light, they are useful for considerations in the comparative analysis, particularly in regard to data logged under partially completely cloudy skies albeit with the awareness that light shelves' effectiveness is improved under direct sun light. Despite its limits, the method is simple to use and can be considered efficient in allowing the authors to carry out considerations regarding the performance of the system analysed. Among the six different configurations proposed two seem to be the most efficient and are characterized by the presence of an internal highly reflecting surface applied on the ceiling and an external one with two different inclination angles (10° and 20°).

The aim of the research is to determine the economic and energy efficiency usage of the artificial lighting control systems, with the help of astronomical relays and motion sensors, by various types of light sources for the stairwells (stair landings and staircases) of multistory residential buildings. The analysis of the residents' monthly movement intensity of the 9-story residential buildings through the buildings entrance, doorways, and apartment doors was carried out. The economic and energy efficiency of use the artificial lighting control systems with an astronomical relays and motion sensors with different types of light sources was determined. Regardless of the light sources` type, the astronomical relay's use leads to reduction in the electricity consumption of artificial lighting in 43.31%-50.52%. Moreover, the motion sensors' use on stairwells leads to a significant reduction in electrical energy consumption: in a case of halogen lamps-by 97.73%, compact fluorescent lamps-by 95.27%, light-emitting diodes lamps-by 93.98%. For the first time, the data of 9story residential buildings inhabitants' traffic intensity through the first-floor doorway for the Ternopil city, Ukraine has been carried out. It has been proved the economic feasibility and energy efficiency of using combined lighting with an artificial lighting control system for stairwells of multistory residential buildings.
