Abstract
Energy-efficient building design models are one of the factors that need to be considered in building planning. In the morning to evening, sunlight as a source of natural light can be used as a source of lighting in buildings. By utilizing natural light, it will reduce energy consumption in buildings. Air conditioning and lighting are important factors in designing energy efficient buildings. In this study, analyzing natural and artificial lighting at Graha Pena Makassar Building. The research method is quantitative by measuring and analyzing several workspaces that are directly and indirectly related to openings in the building envelope. statistical descriptive analysis, namely entering data into tables and graphs, then analyzing the level of illumination in the analyzed workspace. The research objective was to determine the level of illuminance in several workspaces with different orientations. How is the effect of natural light distribution on building orientation and how is the artificial lighting system at workspace in the Graha Pena Makassar. The results showed that the orientation of the building had an effect on the distribution of natural light into the space. The spatial orientation facing East has a higher distribution of natural light than that of the south. Workspaces that are not directly related to window openings in the building envelope are using artificial lighting systems in the form of lights. The workspace has uneven illumination levels in its work area, because the layout and placement of lighting points have not been well planned. The contribution of this research is a reference in designing a building facade design with an attractive appearance, and can maximize the use of solar energy as a source of natural lighting, while still paying attention to the visual comfort of space users.
Highlights
The optimization of lighting systems in buildings is to consider the integration between natural light and artificial light
The analysis of the effect of building orientation on the distribution of natural lighting and analysis of the placement of artificial lighting so that the level of illumination is evenly distributed in the workplace
The results of this study indicate that the level of illuminance along the building envelope openings has an illumination value in excess of the recommended SNI 036575-2001 illuminance standards, especially on research objects in the Graha Pena Makassar building
Summary
The optimization of lighting systems in buildings is to consider the integration between natural light and artificial light. Maximize the use of natural light into the room, can minimize energy consumption as an artificial lighting source. Some considerations of negative effects, in the use of natural light include: thermal, glare, ratio and the value of brightness. An understanding of the luminance distribution is very much needed as a reference in building lighting planning. The International Commission de IEclairage (CIE) which has approved two international standards on the distribution of standard sky luminance (1955) cloudy sky and clear sky (1973). Rahim R (2007) stated that Intermediate sky condition, namely the condition of the sky between clear sky and cloudy sky, can be found from various parts of the earth, especially in the equatorial hemisphere
