Measuring sunlight using horizontal and vertical section as a judgement sample toward sun path system. Skylight distributed fully from skylights to
the atrium in ground floor area. Result of analysisshowing the effectiveness skylights in Galeria mal its recorded 300Lux in optimum percentage of 90% with range 0-100%. Skylights is very important to optimize solar energy and also decreasing lighting in the daylight
