Analysis of Daylight Distribution on Building Height and Space Depth.

Abstract

Lighting design is one of the priorities in designing buildings. Natural lighting can reduce energy consumption in buildings. Aesthetic levels are the basis of the planning concept, but need to pay attention to the concept of using natural lighting, in order to realize the energy-efficient building design. The purpose of the study was to determine how the level of illuminance affects the opening area, depth of space and height of the building. Quantitative research method is to analysis statistical data from measurements of illuminance levels in space. The results of the study concluded that the level of illuminance in the meeting room of the Center of Technology building in Hasanuddin University exceeded the illuminance standard. The extent of openings in the building envelope affects the illuminance level in space. Natural light distribution affects the height of the building's floor and the depth of space. Based on this conclusion, it is expected that in designing a building it is necessary to pay attention to the building facade, so that the distribution of natural light is not too high into the building and to avoid negative effects such as glare, high brightness and contrast.
