“…For instance, one of the SDA-metrics and the UDI-metrics must be used. A supplementary use of ASE is also important because it may seem to differ dramatically depending on the orientation [5]. A study of the new metrics for the dynamic and temporal elements of daylight has concluded that practitioners separate dynamic shades in the ASE requirement simulation methodology is a problem that not only makes it very difficult for projects to approve the scale but also nullifies the LEED Spatial Daylight Autonomy (SDA) association scale since its dynamic shades is a primary way to increase daylight while trying to control glare [6].…”

In the climate-change period, all countries strived to design sustainable buildings. As environmental influenced contributes to design decisions, to save energy and to achieve the sustainable development indicator according to Egypt Vision 2030. This can be achieved by accessing the maximum of daylight, consequently the facade design has a major impact on daylight performance. This paper aims to evaluate the daylight performance by using dynamic shading, in a university classroom in Egypt. It also aims to determine the optimal angle for each hour of the shade's movement. Based on LEED 4 daylight requirements and IES, daylight analysis was integrated using DESIGNBUILDER V6, RADIANCE, and DAYSIM programs. The simulation measured the basic case of the case study and then compared it with using dynamic shading system. Incrementing the efficiency of daylight needs to increase spatial daylight autonomy (SDA) and reduce annual sunlight exposure (ASE); hence, the importance of this research is to take up studies of spatial daylight autonomy (SDA), annual sunlight exposure (ASE), useful daylight illuminance (UDI), working plan, and daylight factor over a year. This paper proved the necessary of using dynamic shading system. As it helped in changing the angle of inclination shading system with change the angle of inclination the sun on the openings of the building. It adapted the change from the educational activity (the whiteboard and data shown) in the case study. If the opening has wide areas in the eastern facade, the overall value of illumination at 9 a.m. is much higher than at 3 p.m. When using dynamic shades, the daylight efficiency is raised, in detail, by UDI, ASE, and the daylight factor raised by 58%, 45%, and 4.3%, respectively. This research will help architects and decision-makers to improve lighting performance in existing university buildings. It also achieved visual comfort in the classroom.

“…Balconies produce impacts in four factors that contribute to the indoor environmental quality (thermal, visual, acoustic comfort, and indoor air quality) [13][14][15]. The light reflectance value is an important parameter when the main part of the daylight contribution comes from the internally reflected component as in the case of a deep and long balcony [16,17]. The authors of [18] developed a framework called the residential daylight score.…”

The reconstruction of balconies and loggias is a key element of the renovation of apartment buildings. Artificial light will never replace natural light. Every day, one must make full use of the potential of daylight and enjoy an advantage—free-of-charge natural light entering the interior. When renovating balconies, people often change the character of this protruding structure from a façade to a loggia. This is also the subject of this paper. For the evaluation of the daylighting conditions prevailing in residential building, the Daylight Factor (DF) was considered as the parameter for indicating the quantity of admitted daylight. The DF values and illuminance—CIE overcast sky were calculated using DIALux 9.1 software. The aim of the paper is to compare two variants of the level of daylight in the rooms of the residential building. One option to bring in even more natural light than a window is a variant with balconies. Loggias are satisfactory in terms of static and thermal technology, but daylight conditions are deteriorating. The article provides an insight into the solution of the renovation of balconies and loggias in a specific apartment building. The result shows their influence on changes in the conditions of natural daylight in the interior of two selected rooms.

The rational use of daylight can significantly reduce the cost of electricity for artificial lighting. This research aims at investigating the parameters of translucent structures of building envelope, and the value of daylight factor, for which maximum efficiency of daylight usage is achieved in office rooms. The study analyzes the dependence duration of daylight autonomy in office rooms, on the value of daylight factor for four European cities. The specific daylight autonomy (h/(year•m 2)) of office rooms were found. It was proved, that regardless the size of the rooms, the maximum specific daylight autonomy in Ternopil city (at illumination of 300 lx, which is prescribed by regulations), with lateral daylight, occurs when the daylight factor is in the range of 1.7% to 1.9%. Maxima-at 1.8%. At illumination of 500 lx, the maximum specific daylight autonomy will occur at a daylight factor range of 2.6% to 3.0%. Maxima-at 2.8%.
