2. 1.0 Introduction
1.1 Objective
the primary objective of this project is to integrate the principles of lighting
requirement into the design of suggested context, which requires to build an urban
infill library in Jalan tar. The aim is to encompass daylighting and artificial lighting
system into the library and implement PSALI design strategy as well. The
understanding of lighting system is important in order to solve design problems.
1.2 Project Introduction
The community library is located at Jalan Tar, The building is orientated towards
east west, Hence receiving sunlight on the front and back of the building. It is
important

3. 2.0 Daylighting Lighting
2.1 Daylighting factor Analysis
Daylight factor is a ratio that represents the amount of illumination available
indoor relative to the illumination present outdoors at the same time under
overcast skies.
Where,
Ei= illuminance due to daylight at a point on the indoor working plane
Eo= The unobstructed horizontal exterior illuminance, average daylight level in
Malaysia(EH) is assumed to be 32000 lux
A standard sky is assumed to give a minimum level of illuminance on the ground

4. In side-lit rooms, the maximum DF is near the windows, and it is mainly due to
the sky component. In the early stages of building design, the average daylight
factor may be used to assess the adequacy of daylight
Where,
W= area of windows
A= glass transmittance correction for dirt
= visible sky angle in degrees from centre of window
R= average reflectance of area A

Light Contour
The study area has a daylight factor of 5.37%and
natural illumination of 1074 lux. Based on the
requirements of MS1525 shown in table 2.1.1, this
space has a bright natural daylighting as it is within
range of 3-6.

7. 3.0 Artificial Lighting Analysis
Lumen method
Lumen method can be also calculated and used to determine the number of
lights should be installed on the site. To know the number of lamps, calculation
of total luminance of the space need to be done based on the number of
fixtures and examine the sufficiency of light fixtures on that particular space
Room Index
Room index, Ri, is the ratio of room plan area to half wall area between the
working and luminaire planes, which can be calculated by
