This document discusses lighting design for two spaces - an indoor reading room and gallery cafeteria - in a community library project. It analyzes daylighting factors and artificial lighting needs for both spaces based on Malaysian standards. For the reading room, the daylight factor is calculated as 4% and artificial lighting specifications are provided for 33 ceiling mounted LED panels arranged in 3 rows. For the cafeteria, the daylight factor is 2.67% and 49 downlights arranged in 7 rows are specified. Diagrams show daylight contours and permanent supplementary artificial lighting schemes for both spaces.

3. 1.0 INTRODUCTION
1.1 OBJECTIVE
This project aims to understand the integration of lighting principles in the
community library of Project Design Studio 5 which able to solve their design
problems in relation to sustainability issues (natural lighting and site analysis).
Students would be able to design spaces incorporating artificial and day
lighting thus create good design by integrating lighting well.
1.2 PROJECT DESCRIPTION & SITE ANALYSIS
The site is located in Petaling Street, Kuala Lumpur area which allows the people
to have an issue of lacking a greenery node space for the communities. They
need a free public space that brings them together through the activities and
programme in a space. Therefore, community library is designed in the context
where involved different communities to be gathered in a same space to having
the chance of interaction within themselves and achieving the goal of making
the site to be more happening by strengthen the bond between the people on
the area.
Picture above shows the site location in Petaling Street where the facing the
east to the back alley and to the west of the front main road.

2.1 DAYLIGHTING
DAYLIGHT FACTOR
The daylight factor is commonly used to determine the ratio of internal light
level to external light level and is defined as follows:
DF = Ei x 100%
Eo
Where:
DF: Daylight factor
Eo: simultaneous outdoor illuminance on a horizontal place from an
unobstructed hemisphere of overcast sky.
Ei: illuminance due to daylight at a point on the inddor working plane.
According to MS 1525, Daylight factor distribution as below:
Daylight factor, DF
DF, % Distribution
>6 Very bright with thermal & glare
problem
3-6 Bright
1-3 Average
0 Dark
ARTIFICIAL LIGHTING
Artificial lighting is defined as any light that does not come from the sunlight
which is a technical instruments that generate the light through the electrical
energy. Artificial lighting is required for each space as substitute light as we do
not receive the sunlight in 24 hours.

5. 2.3 INDOOR READING ROOM (SPACE 1)
DAY LIGHTING
The selected area, indoor reading area located at first floor is selected to be
studied for day lighting. This area is partially surrounded with curtain wall glass
which allow light penetration to be applied to the area. A lot of light is needed
to light the space up as it allows people to read books comfortably. If the
daylight is sufficient to light the place up, less artificial light is needed and
therefore less energy is required.

DAYLIGHTING CONTOUR DIAGRAM
The space does not receive much daylighting to reduce the glare of sunlight in the
morning. The room receives an average of 800 lux of daylighting. The room receives
more light through openings. Hence, this room requires the artificial light to light the
room up.

8. ARTIFICIAL LIGHTING
According to MS 1525, 2007 standards, the artificial lighting that needed to light up
the indoor reading area is 300 lux. Type of luminaire used as shown below:

2800 x 0.6 x 0.8

= 33 Lamps
Spacing to height ratio 3.2m x 1.5= 4.8
Fitting Layout by approximately (m) Therefore, approximately 33 lamps = 3
rows of 11 lamps
Length of room = 15m
Width of room = 10m
Spacing between each bulb (L)
=15/11
= 1.36m
Spacing between each bulb (W)
=10/3
=3.33m
33 lamps are required for the space which is 3 rows of 11 luminaries each arranged
accordingly so there is adequate light for the space to be lighted up with artificial
lighting.

The space receives natural light from the windows (left side). The red
light will be turned on if the natural lightis not strong while the orange

11. and yellow lights will be turnedon as the natural light cannot penetrate
to the deeper space.

DAY LIGHTING
The gallery cafeteria located at ground floor is selected to be studied for day
lighting. This area is partially surrounded with curtain wall glass which allow
light penetration to be applied to the area. A lot of light is needed to light the
space up as it allows people to read books comfortably. If the daylight is
sufficient to light the place up, less artificial light is needed and therefore less
energy is required.

49 lamps are required for the space which is 7 rows of 7 luminaries each arranged
accordingly so there is adequate light for the space to be lighted up with artificial
lighting.

INTERIORS (PSALI)
The space receives natural light from the windows (left side). The red
light will be turned on if the natural lightis not strong while the orange
and yellow lights will be turnedon as the natural light cannot penetrate
to the deeper space which is quite large in area.
