Natural lighting analysis in Plaza Senayan, Jakarta, Indonesia

Abstract

As the development of malls went more advanced, there are malls in Jakarta that keeps up with the trend, while some others are left behind. A mall does not only function as a shopping center, while also catering for some other functions; to socialize, meeting place, hanging out, studying, and working. Visitors could experience something that couldn't be obtained elsewhere. Lighting is the most important aspect in the interior design of malls, to create an ambience in order to increase sales. This research is conducted to study on the effect of skylight shapes to natural lighting distribution in Plaza Senayan. Qualitative & quantitative methods are used with explorative approach, along with real measurements in the areas of the shopping mall covered by natural lighting. Building orientation, building shape, skylight shape, natural lighting distribution, and lighting intensity are the indicators used in this study. Field exploration was analyzed with current codes, and a simulation was conducted using Velux Daylight software to see the lighting distribution as well as the solution. Research results show that there are areas that hasn't fulfill the minimum lighting intensity requirement, areas with too much lighting, far from current standards. Results show that natural lighting distribution on square skylights are more evenly distributed than circular or hexagonal skylight shapes. This shows that skylight shapes does have an effect towards natural lighting distribution.
