Daylighting simulation analysis for sun shading on hotel design in West Jakarta

Abstract

The main objective for this paper is focused on an evaluation of sun-shading daylighting in a four-star hotel design mass. The daylighting has potential and considers as the best strategy for energy saving. Lowering energy costs can directly increase revenue, coupled with the potential for gradual increase in PLN electricity. Apart from financial and service benefits, saving energy is also a form of concern for the sustainability of the environment which has an impact on social life. The method that used in this paper is quantitative simulation, which is presented in the paper by specification of daylighting in a four-star hotel design on solstice day, 21st December. The simulation is done by Velux Daylighting Visualizer, with a couple of lost variables. The simulation for this condition represents two extreme cases for maximum and minimum daylight levels in annual evaluation.
