  • 4. TEST 4 Daylight The roof shape in this test has changed from flat to slope roof to maintain view from the towers and to be more blend with common roof shapes in the neighbourhoods. Four rooflights added on the roof and the length is facing south. As demonstrated in the graph, three rooflights are close with each other to provide more lights at the audience area and less light at the stage area. Adding that much amount of rooflights and maintaining small windows on the wall create an excessive illuminance. Each rooflights has a retractable shading device that can be fully closed, half closed and open to control the amount of natural light entering the room (Figure 6) Figure 6: Roof light Shutter The Association of Rooflight Manufacturers classified two types of rooflights: direct light and diffuse light. It is called direct light when light enters the building without any interfererence, like a straight beam. On the other hand, diffused light scattered to surfaces of the room giving more even light distribution. Daylight Factor % 7.2% Illuminance (Lux) 200 - 1400 Uniformity 0.26 source: IES VE 13
