CHAPTER 1.0 INTRODUCTION
1.1 Objectives
The intention of this project is to incorporate the lighting analysis and design in to the community
library project to presents the understanding of artificial lighting and daylighting strategies to solve
environment problems in relation to sustainability and user comfort, at the same time practice use of
potential natural lighting. As the position of site selected faces the East - West, where daylighting is
an critical issue if not adopted appropriately, utilisation of natural lighting is encouraged but at the
same time provide a comfortable spatial qualities for each functional area.
1.2 Project Introduction
The community library is located at Jalan Tuanku Abdul Rahman, Kuala Lumpur, an infill project
between the Coliseum Cafe and Wisma Harwan. The design intention of my proposed library is to
congregate experiences and to redefine perceptions of Malaysians towards the immigrants
community. Thus, forming a humanistic library, a library beyond the collection of books and written
knowledge.
The application of natural lighting through facade, skylight and light wells to enhance the spatial
lighting quality aims to reduce the use of artificial lighting, enabling users to experience the details
of Jalan Tuanku Abdul Rahman through tactile senses. Therefore, well integration of artificial
lighting and daylighting is required to achieved the poetics of space and structure as well as to
provide sufficient luminance to the functional space according to its purposes in order to maintain
the comfortable visual condition for users.

1.4 Sun Shading Diagrams
At this hour, incident light travels from the East direction, which penetrates through the front facade
in to the interior spaces. The front spaces of the library like casual reading space, young adult’s
department, and antique archive gallery will be affected throughly. Therefore, the front facade will
be installed with varieties of sun shading system depending on the function of the space. Light
travels in to the spaces though light well will not affect the lighting condition much at this hour.
Date Time Weather
16th July 2017 0830hr Sunny

At this hour, the incident light is coming dominantly from the top of the East direction. Spaces
affected by the source of light will be Lounge, which is located at the top floor. This issue is solved
by using sun screens as continuation of roof design over the facade exposed to sunlight. Other
spaces were not seriously affected by the sunlight at this point of time as light travels through light
well in to these spaces, reducing glares and thermal discomfort by avoiding direct light and
reflecting light.
Date Time Weather

The late afternoon sun affects mainly on the spaces located at the back of the building. For example,
the meeting room that is located at the top floor. Spaces located below are protected by wall built
for privacy of restrooms as well as the adjacent building. However, it is still important to provide
sun shading system to reduce direct penetration of light in to the the space mentioned above. The
application of operable solid wooden panels and louvers are used to prevent direct light at the same
time, provide flexibility when natural light is needed. Light traveling through light well is diffused
by the office spaces and the green wall installed in between two spaces to provide boundary.
Therefore, the flexibility of use of facade is vital for the utilisation of natural lighting.

CHAPTER 2.0 SPACE A . E-LEARNING DEPARTMENT
2.1 Introduction
Figure 2.1.1 Second floor floor plan with indication of location of Space A.
The chosen space is a semi open area located on the second floor. Curtain is applied on one end of
the space to avoid indirect light that reflects from the devices’ screen, causing discomfort like
glares. Natural light received by the space through the light well is insufficient for a computer room
based of the standard stated in MS 1525. Therefore, artificial lighting is needed throughout the day
to provide sufficient illuminance level for the assigned activity in the space.

2.2 Daylight Analysis
Daylight Factor Analysis
Based on the daylight factors and distribution table stated by the Department of standards Malaysia,
2007, the space is fairly lit by the natural lighting.
As from the calculation stated above, daylight received was just enough to achieved the requirement
of illuminance level as stated in MS 1525.
Floor Area (m²) 7.1 x 5.7 = 40.21m²
Area of Facade exposed to Sunlight (m²) (0.9 x 3.5) + (2.141 x 3.5) = 23.625
Daylight Factor, DF DF = 40.21 / 23.625 x 100
DF = 17.02 x 0.1
DF = 1.7%
Zone DF (%) Distribution
Very Bright > 6 Large (including thermal and glare problem)
Bright 3 - 6 Good
Average 1 - 3 Fair
Dark 0 -1 Poor
Standard room Illumination recommendation by MS 1525 for computer rooms: 300 lux -
400 lux
External Illumination (Shade illuminated by the
entire clear blue sky)
20000 lux
DF = Ei (indoor illuminance) x 100%
Eo (outdoor illuminance)
1.7 = Ei x 100%
20000
Ei = 340 lux

Daylight Lux Contour Diagram Diagram
Figure 2.2.1 Daylight contour of Space A.
Based on the daylight analysis diagram, it is presented that the light enters the E-learning space
from the openings towards the light well. The natural light received gradually decreases as it travels
deeper in to the space. Thus, incorporation of artificial lighting is needed.
Section analysis Diagram
Figure 2.2.2 Section of Space A with shadow casting.
The E-learning Department has daylight factor of 1.7%, which achieved a fairly lit environment due
to the opening towards the light well that allows reflectance of natural light in to the space. The
indoor illuminance of space is at 340 lux, positioned at the mid point of range 300 lux - 400 lux a
stated in MS 1525. Thus, artificial lighting is needed throughout the day to achieved even
distribution of light throughput the space as well as to provide sufficient illuminance level when
daylight is not available when weather changes.

lamps on the sixth )

Artificial light Lux Contour Diagram
Figure 2.3.2 Artificial light contour of Space A.
The contour diagram shown above presents the lighting condition after the artificial lighting is
installed and planned according to the analysis and calculation above. The light source is more
evenly distributed to the working plane as compared to the light contour diagram in Figure 2.2.1.
Bulb colour of cool white is chosen to create a more formal ambience for the working space.
Pendant light is used to reduce the amount of light needed as it is in relation of the figure of
Utilisation factor, UF, where it is indirectly proportional to the number of light fittings needed.
Figure 2.3.3 Section of Space A after application of artificial lighting.
The inner portion of the e-learning space has no direct opening due to the location of restrooms that
blocks the exposed area of back facade. Thus, the deeper part of space are mainly brighten up by the
installation of artificial lighting to introduce balance distribution of light.

CHAPTER 03 SPACE B . CASUAL READING SPACE
3.1 Introduction
Figure 3.1.1 First floor floor plan with indication of location of Space B.
The chosen space is a semi open area located on the first floor. Facade with installation of sun
shading system is positioned on one end of the space to avoid direct light penetrating in to the
space, causing discomfort like glares and thermal discomfort. Natural light received by the space
through the light well exceeds the the requirements as stated in MS 1525. Therefore, design
strategies are needed to be applied to prevent regrade of spatial experiences and working ambience.

Based on the daylight factors and distribution table stated by the Department of standards Malaysia,
2007, the space is brightly lit by the natural daylight.
As stated in the calculation above, daylight received has slightly exceeds requirement of
illuminance level as stated in MS 1525.
Daylight Lux Contour Diagram

Ei = 1220 lux

The light contour diagram shows that the space lit up by daylight from the expose facade area on
one end and from the light well on the other. It is presented that the illuminance level decreases as it
reaches the centre of space, forming unbalance light distribution throughout the space.
Figure 3.2.3 Section of Space B with shadow casting.
The casual reading space achieved daylight factor of 6.1% and natural illuminance level of 1220
lux. Based on the standards stated in MS 1525, the space is bright lit by daylight as both figure
exceeds the required figure. For instance, the bright daylight factor range from 3% - 6% and the
suggested light level for reading space is 300 lux - 500 lux. Therefore, design strategies are require
to reduce sun exposure to prevent issues of discomfort like glares and thermal discomfort.

The lux contour diagram presents that the light fittings installed are able to illuminate the casual
reading space when daylight is not available as well as to provide an even distribution of light
throughout the working plane. However, corners of the room are relatively dark as compared to the
front and centre area of the space.

3.4 PSALI Scheme
Figure 3.4.1 Lighting layout arranged to incorporate with daylight utilisation.
Figure 3.4.2 Section showing the lighting layout of artificial lighting system.

The artificial lighting introduced to enhance the illumination of chosen space when natural lighting
is not sufficient to cater with requirement as per listed in MS 1525. The total of 20 light fittings are
controlled by a one-way-two-gang switch, and two single switches. During the brightest portion of
the day, daylight factor at its highest, only row B needs to be switched on. The series of row C can
be turned on in place of row B to increase the illuminance level of space. Row A and D all only be
switch on when daylight factor is at its lowest, at night or during the dark days.
Design Strategies
Figure 3.4.3 Front facade of building with indication of material used.
To reduce possibility of issues like thermal discomfort and glares, louvers and double glazing low-E
glass panels have been applied to the front facade exposed to daylight. The floor platforms have
been set back by 1000mm to form a buffer some to allow natural ventilation to eliminate heat gain
by building facade. Double skin facade fired was also able to improve the comfort ambience of
space as well as reduce consumption of energy.
