Lighting

1.1

Day Lighting ( Discussion Area )

According to MS 1525, Daylight Factor distribution as below: DF, % >6 3-6 1-3 0-1

Distribution Very Bright with thermal & glare problem Bright Average Dark Table 01: Daylight Factor according to MS 1525.

Discussion area is located at the 4th floor. The partition wall of the discussion room is made of laminated glass. The space received sunlight from the front facade which is also made of laminated glass. Hence, there is minimal artificial lighting will be using in this area.

Day Lighting ( Cafeteria )

According to MS 1525, Daylight Factor distribution as below: DF, % >6 3-6 1-3 0-1

Distribution Very Bright with thermal & glare problem Bright Average Dark Table 02: Daylight Factor according to MS 1525.

Cafeteria is located at the ground floor. The cafeteria is surrounded by brick wall . The space received sunlight from the skylight which is also made of laminated glass. Hence, there is minimal artificial lighting will be using in this are

Conclusion: The reverberation time for the discussion room at 500Hz non peak hours is 0.66s.According to the standard of reverberation time, the standard comfort reverberation for a discussion room is between 2.05s-1.7s. Hence, the reverberation time for my discussion room in the library is within the standard comfort reverberation time.
