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 = 𝐸𝑖

𝐸𝑜 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

Table 1: Daylight factors and distribution

(Source: Department of Standards Malaysia, MS 1525:2007)

Admin Office

DF = 𝐸𝑖

𝐸𝑜 X 100%

DF = 6478

32000 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.

This space is very has good daylight factor, hence the use of PSALI to control the use of artificial

lightings.

𝑇𝑎𝑣 , where 𝑇𝑎𝑣 = Average transmission coefficient of materials

𝑆𝑅𝐼𝑛 = 10log10 1

𝑇𝑛 , 𝑇𝑎𝑣 =

Conclusion: Therefore, the average sound level at the culinary studio is 52.7dB. To reduce the

noise produced by the street towards the building, green wall can be installed on the facade of

the building which acts as noise barrier or using furniture for sound absorption materials such as

carpets, cork flooring

Conclusion: Therefore, the average sound level at the demonstration kitchen is 51.3 dB. To

reduce the noise produced by the street towards the building, green wall is installed on the

facade of the building which acts as noise barrier. The building interior also has some vegetation

to mask noises from exterior noise.
