This research examines the natural and artificial lighting performance comparison in an architecture classroom at a university in southern Thailand and gives principles for enhancing lighting design. The sample for the study was classroom spaces. The efficacy of natural and artificial lighting was studied using static and dynamic models, and data were obtained using a 4 in 1 multi-function environmental meter at various times of the day. The current study adopted the IESNA (Illuminating Engineering Society of North America) and CIBSE (Chartered Institution of Building Services Engineers) lighting standards for the performance comparison analysis. The results showed that the natural light in the classrooms did not satisfy the standards for lighting levels. In contrast, the artificial lighting was more effective but raised some issues with uniformity and glare. The study offers recommendations for improving lighting effectiveness, maximizing natural light, reducing energy consumption, improving the uniformity of artificial illumination, addressing issues with various classroom lighting designs, and creating more comfortable and realistic learning environments.

“…Here, optimum glazing configurations for visual performance are very important [38]. If these proposals do not meet the requirements, additional daylight methods should be used as a tool to improve the provision of daylight in existing education areas [39]. Lighting efficiency of the vertical window and roof window at a distance from the peripheral wall (source author, processed according to [15]).…”

Influence of Roof Windows Area Changes on the Classroom Indoor Climate in the Attic Space: A Case Study

Windows are a complex part of building design and provide a considerable benefit, including to school buildings. For the evaluation of the daylighting conditions prevailing in classrooms, the daylight factor (DF) was considered as the most appropriate parameter for indicating the quantity of admitted daylight. The DF values and CIE overcast sky were calculated using Velux Daylight Visualizer 3 software. The task of the paper is to compare various roof window openings in relation to the level of daylight in the attic, looking to optimize the use of the attic for teaching. The indoor air temperature has a general influence on comfort in the interior, in addition to daylight. In winter, the situation is not critical. The thermal insulation properties of packaging structures are sufficient. The situation is worse in summer, due to the fact that the heat-storage properties are undersized and there is excessive overheating of the indoor air. Four variants of roof windows and their influence on the overall microclimate in the attic are compared. The variant without roof windows is a suitable solution with regard to minimum overheating, but the worst situation for daylight. In order to receive even more light from the window (by moving windows to the top of the roof), we can use variant 2. Based on a combination of daylight calculations and summer temperature, a graphical dependence on window size prediction in terms of top and combined lighting is derived. This was hypothesized without shading the windows. Of course, the shading elements of these windows or cooling are expected in the summer. Finally, the energy required for cooling is compared depending on the size of the windows and achievement of the permissible temperature.

 A method proposal to determine the effect of the changes in the strengthened buildings on the visual conditions  Examining the visual comfort conditions of an educational building with the proposed method  The importance of structural system design in the efficient use of spaces in terms of visual comfort Figure A. Examination steps of the visual comfort changes of the strengthened educational building Purpose:The aim of the study can be summarized as proposing a method for determining and improving the visual comfort in buildings damaged by an earthquake and renewed by reinforced the structural system, and in this context, determining the changes in the visual comfort conditions building whose structural system has been strengthened and making some suggestions for improvement. Theory and Methods:In line with this aim, according to the proposed method for the strengthened buildings, the lighting conditions (natural, artificial, integrated) in the before and after of classrooms, which are assumed to be typical of an existing education building, were examined and evaluated in the context of relevant standards, and some improvement designs were offered. Results:The findings revealed that although the lighting conditions were more favorable before retrofitting the examined building, it was generally not sufficient in terms of the standards in before and after cases, and new designs should be created for required conditions. As a result of the study, it has been determined that more attention to the lighting technique and the effects of natural and artificial lighting in the interiors will be more positive in terms of energy efficiency, using natural resources, and creating appropriate indoor conditions for visual comfort. Conclusion:of the spaces and especially the visual comfort. The issue to be considered is that while the inevitable strengthening changes are made, it is necessary to produce solutions that do not compromise the comfort conditions of the users. The methods proposed in the study and the examination methods and suggestions used specifically for the classrooms will contribute to the creation of suitable conditions for visual comfort and energy efficiency in the spaces in the retrofitted buildings.
