Results of the Analysis

5.0 Results of the Analysis

The results are illustrated in Table 2 and 3, and Figure 4 to 9. Results of the analysis comprise comparative study between Karadjoz Beg and Neziraga mosque as follows:

(a). Point 1 Figure 4 shows that the illuminance at Point 1 (location near the mosque entrance) for both of the mosques has the brightest level compared to the other 4 locations ranging from 922 to 33.5 lux. The study finds that the average illuminance level at Karadjov Beg mosque is higher than that at Neziraga mosque. The afternoon sunlight from 10:00 am to 2:00pm provides higher illuminance level than those in early morning and late evening sunlight. There is no intersecting point in the Line Chart of Point 1 that indicates both mosques have the same illuminance level during the simulation except at near 7:00am with about 370 lux. The average illuminance level at Karadjoz Beg mosque is 462 lux more than twice higher than that of Neziraga mosque (186 lux). Karadjoz Beg has brighter illuminance level than Neziraga mosque in all hourly simulation from 7:00 am to 6:00 pm. Neziraga mosque has a very bright illuminance level (922 lux) at 6:00am which indicates that it receives direct morning sunlight at Point 1. Neziraga mosque evenly distributed brightness level from 7:00am to 4:00pm ranging from 119 (minimum) to 184 lux under Scale 3 with an average of 156 lux. On the other hand, Karadjoz Beg mosque has better evenly distributed illuminance level throughout the simulation process from 6:00am to 5:00pm ranging from 310 (minimum) to 606 lux (maximum) under Scale 4 and 5 with an average of 491 lux. The morning and evening sunlight provides higher illuminance level than those in late evening sunlight.

(b). Point 2 Figure 5 shows that the illuminance level at Point 2 (location at the central prayer hall) at both of the mosques ranges from 18 to 308 lux. The morning sunlight provides higher illuminance level than those in morning sunlight for Karadjoz Beg and Neziraga mosque. The chart shows that Karadjoz Beg mosque has relatively higher illuminance level than Neziraga mosque at all the interval times. The average illuminance level at Karadjov Beg mosque is 227 lux slightly more than twice higher than that of Neziraga mosque (91 lux). The illuminance level in Karadjov Beg mosque is 155 lux at 6:00am and then the level gradually increases to 308 lux at 10:00am. Afterthat, it has gradual drop to 267, 203, 164 and 47 lux at 1:00, 4:00, 5:00 and 6:00pm respectively. The illuminance level in Neziraga mosque reaches its brightest level (140 lux) at 10:00am. The level gradually hawever decreases to 106 lux at 2:00pm and its minimum illuminance level at 18 lux at 6:00pm. Both mosques have evenly distributed brightness level with Neziraga mosque ranging from 7:00am (110 lux) to 2:00pm (106 lux) and Karadjoz Beg mosque from 7:00am (254 lux) to 5:00pm (166 lux), which means Karadjoz Beg mosque has evenly distributed and higher illuminance levels (mostly under category Scale 4) than those in Neziraga mosque (mostly under category Scale 3).

(c). Point 3 Figure 6 shows that the illuminance levels at Point 3 (location near the mihrab) in the Karadjoz Beg mosque are brighter than those in Neziraga mosque in the simulation ranging from 11 to 199 lux. Karadjoz Beg mosque has higher illuminance levels than Neziraga mosque. There is no intersecting point in the Line Chart of Point 3 that indicates both mosques have the same illuminance level during the simulation. The morning sunlight provides higher illuminance level than those in evening sunlight. The average illuminance level at mosque Karadjov Beg is 156 lux which is 90 lux higher than that of Neziraga mosque (66 lux). Neziraga mosque has illuminance level of 63 lux at 6:00am and gradual decrease to 123 and 101 lux at 9:00 and 10:00am respectively before having a gradual decrease to 75 and 11 lux at 11:00am and 6:00pm respectively. Karadjoz Beg mosque has similar projection starting from 109 lux at 6:00am and then gradually increased to 199 lux at 1:00pm before having gradual decrease to 137, 93 and 31 lux at 4:00, 5:00 and 6:00pm respectively. Karadjoz Beg mosque has evenly distributed illuminance level throughout the simulation process from 7:00am to 3:00pm, in contrast to Neziraga mosque with low illuminance levels less than 125 lux throughout the simulation. Almost all of the illuminance levels at Karadjoz Beg mosque fall under category Scale 3 compared to those at Neziraga mosque under Scale 2.

(d). Point 4 Figure 7 shows that the illuminance at Point 4 (location near south-west wall) at both of the mosques has the illuminance level ranging from 25 to 239 lux. The illuminance levels at Karadjoz Beg mosque from 8:00am to 3:00pm are high above 200 lux and evenly distributed (between 210 and 240 lux) compared to those at Neziraga mosque ranging from 160 to 190 lux. The average illuminance level at Karadjov Beg mosque is 192 lux higher than that of Neziraga mosque (124 lux) with the difference of 68 lux. The illuminance level in Karadjoz Beg mosque is 145 lux at 6:00am and the level gradually increases to 239 lux at 11:00am reaching to its maximum point, before it has gradual drop to 211 and 144 lux at 3:00pm and 5:00pm. At 6:00pm it has sudden decrease to 38 lux. The illuminance level in Neziraga mosque however has its maximum point (189 lux) at 10:00am before having gradual decrease to 160 and 99 lux at 2:00 and 4:00pm respectively, and to its minimum point of 25 lux at 6:00pm. Almost all of the illuminance levels at Karadjoz Beg mosque fall under category Scale 4 compared to those at Neziraga mosque under Scale 3.

(d). Point 5 Figure 8 shows that the illuminance levels at Point 5 (location near north-east wall) in both of the mosques range from 21 to 203 lux. The illuminance levels from 7:00am to 3:00pm in Karadjoz Beg mosque have more than 150 lux with its maximum of 203 lux at 10:00am. The illuminance levels at Neziraga mosque however have less brightness compared to those in Karadjoz Beg (d). Point 5 Figure 8 shows that the illuminance levels at Point 5 (location near north-east wall) in both of the mosques range from 21 to 203 lux. The illuminance levels from 7:00am to 3:00pm in Karadjoz Beg mosque have more than 150 lux with its maximum of 203 lux at 10:00am. The illuminance levels at Neziraga mosque however have less brightness compared to those in Karadjoz Beg

45 lux. The illuminance level in Karadjov Beg mosque is 116 lux at 6:00am and the level gradually increases to 203 lux (maximum level) at 10:00am. Afterthat, it gradually decrease to 156 and 129 lux at 3:00 and 4:00pm respectively and then to its lowest point, 30 lux at 6:00pm. The illuminance level in Neziraga mosque has its maximum point (164 lux) at 8:00am before having gradual decrease to 101 lux at 3:00pm and to its minimum point of 21 lux at 6:00pm. Karadjoz Beg mosque has its brightness levels evenly disributed from 7:00am to 3:00pm ranging from 156 to 203 lux in contrast to Neziraga mosque from 7:00 to 11:00am with 154 to 165 lux. Most illuminance levels are under category Scale 3 except after 4:00pm in Neziraga and after 6:00pm in Karadjov Beg mosque under category Scale 2.
