4. Project Name : Community Learning Centre
Location : Jalan Stesen 1, Klang
Function : Learning Centre
Introduction to Site
Design Intention
This area is an area which is being resuscitated in a sense to
bring local community back together. There are a lot of
boundaries in between the local community. The shopfront
community and the back-alley community, the youngsters
and the elderlies, the old face of Klang and the new faces
to bring into Klang. Rethinking about the area and of
course the needs of local community to communicate and
interact, this learning centre forms and anchor and
connection so that the people can gather here and
strengthen the community.
Design Consideration Through Construction
In order to anchor down the connection in between community, there is a need of certain degree
of visual permeability towards the learning centre. Hence, perforated mesh screen and
translucent corrugated screen façade system are proposed.
For the roof construction system, gable roof is proposed as it’s the roof profile from site. The
learning centre adapt the roof profile to have a continuity and similar language with the site
context.
In order to anchor the relationship of young and old, not just through remaining the old elements
but also to add in new elements. Hence, steel structure which is a post-modern construction
design is introduced.

Advantages of Perforated Screen
1. Aesthetic
With virtually endless options in holes shapes,
size & geometric pattern, perforated screen
adds visual interest to the building’s exterior.
It allows occupants to enjoy exterior view
while maintaining a certain degree. Allowing a
comfortable level of natural lighting during the
day, perforated screen reduces the amount of
artificial lighting needed, while at the same
time deflects heat.
2. Versatility
Aluminum perforated screen used is versatile.
It used as lightweight decorative element for
the building. It allows a multitude of options
to explore. For example, screen as sunscreens
that filter lights, railing infills that add
structure while reducing mass, enhance
aesthetics of buildings etc.
Disadvantages
1. Connections have to be carefully sealed
and waterproofing need to be done to
avoid water penetration into building
during rain
Design Consideration
1. Privacy of spaces
2. Suitability to site context
3. Durability
Perforated aluminum screen able to withstand
harsh weather environments, with the ability
to control the pressure. The perforation also
decreases the weight needed to be supported
by the building’s framework.
4. Energy Efficient
Perforated aluminum screen allows the
balancing of light & ventilation. By deflecting
heat, less energy output is required, providing
a more consistent interior temperature. As a
screening element, perforated metal
decreases the amount of indoor lighting
required.
5. Eco – Friendly
Minimize resource depletion due to its
recyclability, reduces energy in use, promotes
sustainability . Perforations decrease amount
of metal used, which translates to reduced
weight and lower fuel transportation costs to
building site

Strcuture
Advantages of Corrugated Screen
1. Aesthetic
Translucent perforated screen allows certain
degree of exterior view towards the interior
while maintaining the privacy. The translucent
screen allows comfortable level of natural
lighting into the building during the day. This
natural lighting allows the building to have a
lesser amount of artificial lighting. At night, lights
from the interior shines out to the exterior and
gives a pleasant view for the passer-by.
2. Durability
Virtually unbreakable and can withstand massive
force. Besides, corrugated screen are light
weight materials which help to reduce the
weight to be supported by building’s framework
Disadvantages
1. Corrugated screen are not very resistant t
scratching & marring. As a result, denting is
possible on the surface if care is not taken
2. Manufacturing process is not environmental
friendly as it requires a very high processing
temperatures.
3. Highly sensitive to organic solvents. Hence,
maintenance work need to be careful
Design Consideration
1. Privacy of spaces
2. Suitability to site context
3. Cost Effective
Light weight compared to glass, acrylic or other
plastics. This results in easy transportation,
installation and lower lab costs which is a big
consideration for building cost
4. Energy Efficient
Translucent corrugated screen allows ultraviolet
blockage while allowing sufficient light into the
building. It saves the energy cost in the morning by
providing natural sunlight into the building.
5. Weather Resistance
Corrugated screen has high resistance to sunlight
and rain. This enables the panels to last in the
outdoors for many years without showing signs of
fading, yellowing or discoloration.

27. Conclusion
All in all, both structural and architectural space quality
should be taken into consideration at the same time as
both are quite crucial in affecting the functional and
aesthetic of the building. Losing either one of these
elements will not make the architecture perfect.
Choices of structural system, façade and roof connection is
selected wisely to complement the design of the learning
centre and provide a unique and interesting experience for
the users
