3. 1.0 Lighting
1.1 Daylighting
Natural daylighting is a passive method of lighting up a space. It is the controlled
admission of natural sunlight and diffuse skylight into a building to reduce electric
lighting and saving energy. By providing a direct link to the dynamic and perpetually
evolving patterns of outdoor illumination, daylighting helps create a visually stimulating
and productive environment for building occupants, while reducing as much as one-
third of total building energy cost.
Daylight Factor
The daylight factor (DF) is commonly used to determine the ratio of internal light level
to external light level and is defined as follows:
where,
DF = Daylight factor
EO = Simultaneous outdoor illuminance on a horizontal plane from an unobstructed
hemisphere of overcast sky
EI = Illuminance due to daylight at appoint on the indoors working plane
1.2 Artificial Lighting
Artificial lighting by definition is any light that does not come from sunlight. Artificial
lighting are technical instruments that produces light through the conversion of
electrical energy into radiation and light. Artificial lighting have two types of light source
which is incandescent lamp whereby light is generated when the filament is radiated
at high temperature and luminescent lamp when light is produced through excited
electrons. We do not receive sunlight 24hours and therefore it is important to have
artificial lighting as a substitute.

4. 2.0 Space 1
Knowledge Centre
The Knowledge Centre is an IT room where all the computers are at for local
communities to carry out their computer classes. Controlled lighting in this space is
important to ensure that there is not too much sunlight that will cause glare but
sufficient enough for users to do their work.
The artificial lighting needed to light up the library is 300 lux with the maximum lighting
power of 18(W/m2) based on the MS 1525, 2007 standards.
2.1 Plan

5. The daylight factor that is aimed to be achieved for this space is 4% based on Table
1.1 Distribution of Daylight Factor diagram.
DF = 4%
EO = 14000 lux
EI = EI x 100
EO
EI = 4 x 14000
100
Therefore, EI = 560 lux
2.2 Daylight Contour Diagram
The computer room does not get a lot of daylighting to reduce the glare that the
sunlight causes in the morning because the room is facing the West side where there
is not much sunlight in the morning. The room gets an average of 300 lux of
daylighting. Where there is an opening, the room receives more light. Hence, this room
depends more on artificial lighting especially in the morning.

6. 2.3 Artificial Lighting
The artificial lighting needed to light up the computer room is 300 lux with the
maximum lighting power of 18(W/m2) based on the MS 1525, 2007 standards.
2.4 Light Specifications
Table 1.2: Tubular Florescent Light Tube Description

7. 2.5 Lumen Method Calculation
2.6 Proposed Layout of Lighting Fixtures
10 lamps with the amount of 2100 lumens such as Tubular Fluorescent Light Tube is
needed to light the space up with artificial lighting.
Maximum spacing of each bulb = 1.5m x 2.15m
= 3.225m
10 lamps = 2 rows of 5 lamps
Length of room = 5.2m
Width of room = 6.1m
Spacing between each bulb (L) = 5.2m / 5
= 1.04m
Spacing between each builb (W) = 6.1m / 2
= 3.05m
Table 1.3: Lumen Method Calculation

8. 2.7 Artificial Lighting Interiors (PSALI)
Since both side of the room can depend on natural daylight, the lights indicated in
yellow are mounted together. However, the light in the middle of the room indicated in
orange is proposed to be independent from the rest of the switch because the middle
area of the room do not receive as much sunlight. Therefore, when it is less sunny,
the lights indicated in orange can be switched on.

10. 3.0 Space 2
Youth Workshop Area
The daylighting of the youth workshop area on the ground floor is selected to be
studied for daylighting. This room do not receive ample amount of daylight as it is
placed at the corner of the library. However, if the daylight is sufficient enough to light
up this area, less artificial light is needed and therefore less energy is needed.
3.1 Plan

11. 3.2 Daylighting
The daylight factor that is aimed to be achieved for this space is 5% based on Table
1.1 Distribution of Daylight Factor diagram.
DF = 5%
EO = 14000 lux
EI = EI x 100
EO
EI = 5 x 14000
100
Therefore, EI = 700 lux
3.3 Light Contour Diagram
The youth workshop area get some daylighting in the morning as the window faces
the exterior of the building where it captures natural light. The room needs an average
of 700 lux because it is much larger compared to the computer room, therefore
artificial lighting can be installed to brighten up the place during the evening.

3.5 Lumen Method Calculation
Table 1.4: Round Pendant Light Description

13. 3.6 Proposed Layout of Lighting Fixtures
16 lamps with the maount of 1760 lumens such as Philips Round Pendant Light is
needed to light the space up with artificial lighting.
Maximum spacing of each bulb = 1.5m x 2.15
= 3.225m
= 4 rows of 4 lamps
Length of room = 8.0m
Width of room = 5.0m
Spacing between each bulb (L) = 8.0 / 4
= 2.0m
Spacing between each bulb (W) = 5.0 / 4
= 1.25m
Table 1.5: Lumen Method Calculation

14. 3.7 Artificial Lighting Interiors (PSALI)
Since the side of the room receives more daylighting, the switches are independent of
the lights at the back row that has higher exposure to natural daylight. On a less sunny,
or gloomy day, the front of the room might not receive as much sunlight therefore, the
lights at the front of the room can be turn on without having to switch on the row of
lights nearest to the opening which allows natural daylighting in.
