2.3.1 Daylight analysis
2.3.2 Daylight Photocell arragement

The simulation of daylight anaylsis were conducted by a simplified mpdel of UAL buildings. With general factor of all surface,t the general daylight factor is above 2.2% and the DA can reach 68%. These results shown in the diagram proves this building can harvest fairly enough dalight while working houes, which means daylight should be carefully used in the forth floor.
2.3.3 Annual Sunlight Hour Analysis
Combined with the daylight autonomy and daylight factor for these rooms, we know that this floor is potentially using daylight. A daylight control area of 8m was determined. Using auto-dimming, it can save up to 15% energy when areas are brighter than required.
Annual sunligh hour analysis were conducted by accurated model. The south facade part of both floor 4 and the FBS Hub and received large amount of dayllight.
