Abstract
Solar energy is a light source that can be distributed into buildings as natural light. Energy consumption decreases if it can distribute natural light maximally into the building. The aesthetics of the building will look beautiful when using the facade on the building envelope. Building design without using a facade can be perceived as monotonous or massive. Facade design needs to pay attention to the maximum light distribution factor that can enter the building, considering the effects of glare, high brightness, and illuminance ratio. The purpose of this study was to determine the building facade Model that can distribute natural light as much as possible so as to minimize energy consumption in the building. The design of the facade Model consists of a building without a facade, a flat shape, and a sloping shape. This study uses a quantitative method, namely the illuminance value of the Autodesk Ecotect Program, made in the form of tables and graphs to facilitate the analysis of the simulation results. The results of this study concluded that the facade models have effected on the distribution of natural light, and the percentage of light also affects the depth of space, namely the distance between the windows on the building envelope. Furthermore, the height of the building also affects the distribution of light entering the space. The results of the study concluded that the sloping facade model could distribute light evenly compared to the flat facade model. The illuminance value in the flat shape is only maximal in the area near the window on the building envelope so that it can cause negative effects, namely glare, and brightness. The contribution of the results of this study can be a guide in planning the architectural works of energy-efficient buildings.
