Light Distribution Analysis on Buildings Located on the Coastal

Abstract

Abstract Issues of global warming are important. The effects of illuminance level of natural light on the earth’s surface. The use of natural light into buildings can minimize energy consumption as a source of artificial lighting, but it is important to attention to negative effects such as glare, brightness and thermal. The Aryaduta Hotel building located on the coastal area, is an object of research that needs to analyze the distribution of natural light come in to the building. The purpose of this study was to determine how the distribution of natural light in buildings on the coastal area. The results of research concluded that the farther away from the veil the building then the light distribution will decrease, orientation of the building affects the distribution of sunlight and distribution of natural light into the building affects the sun’s radiation in the morning, afternoon and evening. This research can be the base for energy efficient building design.
