4.53% is in the comfort level, but in order to convey the design concept to the façade, 40 louvres with a width of 300mm are added. Therefore: Awindow = 118 – 40 x 0.3 x 5 = 58 (m2)
And the new daylight factor is: đ??ˇđ??š =
58 đ?‘Ľ 100% đ?‘Ľ0.1 260.51 = 2.23%
The daylight factor is still in the acceptable range and meets the minimum requirement of MS 1525. Multi-purpose hall

With louvres installed, the multi-purpose hall still has a daylight factor of 6.25% which is above comfort level therefore glare and heat problems may occur. Curtains may be used to help control the glare and low-E glass may be used to counter possible heat problems. Artificial lighting Management and administration

According with ANSI, the acceptable noise level for a reading space is 45dB. 48dB has exceeded the requirement but it is designed specially so as the visually impaired requires activity noises to navigate the space. Therefore the sound is not insulated. Internal Noise Seating area
