Lighting Proposal
1.1 Daylighting
Daylight Factor Daylight factor is the percentage of ratio that represents the amount of
illumination available indoors relative to the illumination present outdoors at the same time under
overcast sky. (Malaysia standard outdoor daylight level: 32000 lux)
Equation: Daylighting Factor, DF =
𝐸 𝑖
𝐸 𝑜
X 100%
Ei = Indoor illuminance Eo = Outdoor illuminance = Direct sunlight = 32000 lux
DF (%) Distribution
>6 Very large with thermal and glare problem
3-6 Good
1-3 Fair
0-1 Poor

x 100%
= 20.2%
Conclusion: This space has very large with thermal and glare problems. Hence, thermal
insulation and curtains should be added to reduce glare. The use of PSALI can be used to
control the use of artificial lightings.

The Lumen Method is used to determine the number of lamps that should be installed for a given
area or room.
Formula: N x n = E x A_____
F x UF x MF
N = Number of lamps required
E = Illuminance level required (lux)
A = Area at working plane height (m²)
F = Average luminous flux from each lamp ( lm )
UF = Utilization factor, an allowance for the light distribution of the luminaries at the
room surfaces
MF = Maintenance factor, an allowance for reduced light output because of deterioration
and dirt
