The document discusses the proposed design of the Jalan TAR Community Library in Kuala Lumpur. It aims to create a knowledge hub that encourages reading, sharing ideas, and social interaction. The building orientation allows sunlight in through vertical louvres. Computer modeling was used to test daylighting and balance natural light with artificial light to meet lighting requirements. Key spaces like the staff office, archive, and reception areas were analyzed for daylight factor, illumination levels, and times of optimal natural light to determine artificial lighting needs.

The proposed library is seen as a knowl-
edge hub dedicated to Jalan Tuanku Abdul
Rahman (Jalan TAR) community, be it the local
residence, the office workers from the vicinity, or the
unexpected visitors making casual visit to the place.
Being an urban public space, I do not see it as just
another ordinary library for quiet reading & study
only. My project aims to create an urban structure
comprises of a variety of public spaces that encour-
age reading, sharing of knowledge, ideas, emotion
& stories through informal/spontaneous meetings
among people from different background & culture,
one that completes & complements the existing
urban fabric, one that is filled with impromptu activ-
ities that resonates with the local urban community
spirit, a place to learn, live & play.
The orientation of the building facades are
positioned towards the east & west, directly facing
to the sun. Hence it became essentially important to
induce careful consideration of the amount of light to
be induced to the building. The main feature of the
library is the inducement of sunlight filtered
through vertical louvre, inviting the sunlight into
the voids & library space; that act as a strong
figure that hold the potential to change how
architecture is seen & experience.
Thus,withallthesecomplicatedelements,acomputer
3d model of the library is built & tested with day-
lighting, light contour & PSALI system with analytic
software like revit to ensure maximum efficiency
of natural light & also balance of artificial light for
comfort adhering to the Lux requirement of
MS1525.

unlike generic building that
one spaces being build layer

signed to be blocks by blocks
of spaces with gaps & voids,
generously inviting the natu-
ral element inside.
the porous design of the library tends to receive as much
natural lighting as its can with of gaps, voids & volumes.
Utilising the natural sunlight harvested, to create different
degree of interesting spaces with poetics qualities by playing
lights & shadow, scales & intesections.
SECTION TARGETTED SPACES
The bookracks that fomrs
thewalls&partitionsofthe
library could act as a sun
screen that defused dir-
rect sunlight while pro-
viding sufficient amount
of ambient sunlight for
reading.
The staff office & small archive area of the library has a
daylight factor of 5.2% & natural illumination of 1040
lux. The lux value is higher near the big windows as it is
facing the west. The area receives high amount of day-
light from 3pm to 5pm after which minimum to no shad-
ow casting on the side of the windows opening. 5.2% is
categorized as good based on the requirement of MS
1512. The area is for clerk work desk, archiving of books
& documents That required sufficient amount of light to
process such work. With support from artificial light at
the morning & late evenings, this area will have a gentle
lighting ambience for reading & writing.
Suggestion:
installation of light shelves to reduce strong glare &
light around the openings, while able to distribute light
evenly throughout the space. To be mentioned that the
opening itselves had already installed with wood louvres
as exterior facade; thus further decreasing strong glare
& intensity of light.

The reception of the library has a daylight factor of
1.62% & natural illumination of 324 lux. This is because
the library is designed blocks by blocks & cascaded each
other to allow maximum amount of ambient light pene-
trate down to below; however it is still not enough light
for a reception space.The reception area receives highest
amount of daylight from 10am to 1pm which the source
came from the void atrium above.1.62% is categorized
as fair based on the requirement of MS 1512.However
This area require more sufficient amount of light to wel-
come guest & looks inviting, therefore additional artifi-
cial lighting is required & to install.

The towering library receives most of
sunlight at the rear of its facade (west)
which is where the staff office & small
