1.1 OBJECTIVES
The objectives of this project is to integrate the lighting analysis and design
into our community library which is located at Jalan Besar, Klang, Selangor.
We are required to bring in and utilize as much natural lighting as possible for
the design of our community library to reduce the usage of artificial lighting. As
natural lighting provides a better lighting condition and produce more
comfortable spatial qualities. However, the intelligent integration and
placement of artificial lightings is also another important factor to ensure a
suitable and sufficient luminance in the reading spaces.
1.2 SITE INTRODUCTION
Jalan Besar, is a place with very rich heritage and many different ethnicity. It
is located within the city of South Klang in Selangor. During its early days, this
area was once booming with tin ores and mining industries. After gaining such
resources, Jalan Besar became settlements for the miners and their families
and since then have adopted new lifestyles which are trading and running
businesses in their shophouses. Today, Jalan Besar has become a go to place,
as it has variant local foods and historical sites that not only attract the tourist
but the locals as well. There are two famous landmarks in this area which are
Chong Kok Kopitiam and the KTM station.
4. 2.0 LIGHTING CALCULATION - SPACE A
2.1 DAYLIGHT FACTOR ANALYSIS
Space A is selected for study which is the E- learning space located facing
the south east of the building on the Second floor and is 4 meters high.
Daylight factor is defined as the ratio of interior luminance, Ei to available
outdoor illuminance, Eo which is the unobstructed horizontal exterior
illuminance:
DF= Ei (Indoor illuminance) x100%
Eo (Outdoor illuminace)
Zone DF(%) Distribution
Very bright >6 Large (thermal & Glare problem)
Bright 3-6 Good
Average 1-3 Fair
Dark 0-1 Poor
The daylight factor concept is applicable only when the sky illuminance
distribution is known or can reasonably be estimated. In this case study, the
average outdoor illuminance in Malaysia is assumed according to the standard
which is 20000 lux (Refer to table 2.1.2)
Luminance level (lux) Example
120,000 Brightest sunlight
110,000 Bright sunlight
20,000 Shade illuminated by entire blue sky, midday
1000-2000 Typical overcast day
4000 Sunrise/Sunset
>200 Extreme of the darkest storm clouds
40 Fully overcast sunrise/sunset
>1 Extreme of the darkest storm clouds,sunrise/sunset
7. AVERAGE DYALIGHT FACTOR
Area of windows, (W,m2) 19m2
Total area of internal surfaces, (A,m2
) L= 8.89m H= 4m
W= 4.68m
total area= 191.9m2
Glass transmittance corrected for dirt,
(T)
0.6 , for double glazed window in
clean environment)
Visible sky angle in degrees from
centre of window
60 degrees
Average Reflectance of Area A, (R) 0.35 uncoloured concrete
Average Daylight Factor, (DF) Average DF= W x T0
A (1-R)
= 4.9%
CONCLUSION
The calculation of Average Daylight Factor shows that space A receives 4.9%
of daylight only. In accordance to MS 1525, the average daylight factor of 4.9
is considered as bright. Therefore, the distribution of light is good.
8. 2.2 ARTIFICIAL LIGHTING ANALYSIS
Room Index, RI
Where, L = length W = width Hm = mounted height of fitting above the
working plane
Lumen Method measures the quantity of light reaching a certain surface. It is
the main consideration in designing lighting system. It is used to determine the
number of lamps that should be installed for a given area or room.
Where,
N = number of lamps required.
E = illuminance level required (lux)
A = area at working plane height (m2)
F = verage luminous flux from each lamp (lm)
UF = a utilization factor, an allowance for the light distribution of the luminaire
and the room surfaces.
MF = maintenance factor, an allowance for reduced light output because of
deterioration and dirt
