Daylight distribution in a large multi-purpose hall with complex geometry was analyzed using computer simulations under a limited number of daylight conditions. Daylight conditions included clear glazing with no louvers, horizontal louvers, and louvers positioned at a 45˚under a clear sky at 10:00 AM of the day and year. Average daylight illuminance on each indoor surface was determined for given daylight conditions. Illuminance levels on surfaces were impacted critically by the louver conditions. The daylight illuminance on floor changed significantly as the calculation point moved back from the east-facing window. The contribution of louvers to the daylight distribution was provided. The louvers reduced the daylight up to 44.93% as compared with that of the no louver condition. The correlation between the illuminance on eastside
window surface and on indoor floor was calculated using linear regression in order to predict impact of louver to floor illuminance. The r²values ranged from 0.6066 to 0.9230 according to louver angle. The daylight distribution by ray diagrams and a computer rendering image were presented to show how each surface was impacted by the daylight according to different louver conditions under different season.
