source of natural lighting
From the aspect of lighting, keep in mind that the sun as a source of natural lighting has two aspects to consider, namely the aspect of light and heat. Therefore we must consider both aspects in the design. On the one hand we can take advantage of the cheap lighting during the day so as to avoid the use of artificial light during the day and on the other hand we can push the heat into the building. initial strategy that can be done is through spatial processing, which means that avoided the space in space (space overlap). After all, if it should happen, then the solution is to raise the roof which could allow the placement of the openings above, so that light and air flow can be accessed into the space. A second strategy is to orient the building through the means of openings (windows and vents) on the side of buildings not directly affected by sunspots and also respond to the direction the wind comes (usually north and south sides). The third is to complete the building by means of shadowing either vertically or horizontally. The fourth strategy that can be applied is to maintain the height of the walls and roof that allows light and air into the building and can simultaneously reduce the heat in and the rain splashed from the AIT. The fifth strategy is to apply the lighting from above, mainly to plan buildings that are too broad. In this fifth strategy, aspects of the incoming heat should still be considered.
