Abstract

Lighting system is one of the factors that affect the psychological comfort and user activity of a building. Lighting in a room during the day is obtained from the sunlight, diffusion of light in the sky (cloud overcast), and reflection of light from the surrounding environment. The light received indoors is influenced by window openings, which should meet the size requirement under the SNI (Indonesian National Standard) of at least 1/6 of the room area. Previous research only discussed the optimal size of window openings of a room. This time the researchers sought the ideal window opening position of three different window opening positions in one spatial field. Investigation of internal illuminance distribution was carried out by calculations of sky component on the daylight factor. The internal illuminance distribution investigation results obtained from the sky component calculations were later analyzed with standard deviation and average. According to the analysis in this study, the greater the average and the smaller the standard deviation, the better the distribution value of the room. From the analysis in the simulations carried out by the researchers based on calculations, it can be concluded that the window’s position in the middle of the wall has the optimal distribution. Further research is expected to be useful to architects in window position decision-making in accordance with activity requirements to optimize energy saving by minimizing the use of artificial lights at the daytime.
