3. OVERVIEW
 Green Construction or Sustainable Buildings
 Refers to structure and using process that
environmentally responsible
 Objective are designed to reduce overall impact of
built environment to;
- human health
- natural environment

4.  As technology for sustainable construction
 Plastic material can be change or form by adding
plasticizers and additive to improve certain properties
 Plasticizers is a substance added to increase
workability, flexibility and pliability
 Additives is a substance added to change its
properties and make the end product more desirable.

5.  Application of polymer in green design by incorporate
plastics as green materials and as reinforcement
agent to increase plastic strength
 In conjunction with KL EcoCity, using plastic as main
materials in building a Semi-detached house
 Plastics polymer have a lot of advantage as well as
inexpensive in term of cost
 Design will use variety type of plastics that have
specific structure, types, properties and characteristic
to improve the green construction

 Additional plastics technology
 Conclusions

11.  Material: Insulated concrete form (ICF), rigid plastic foam forms
that hold concrete in place during curing and remain in place
afterwards to serve as thermal insulation for concrete walls.
 Description: ICFs consist of insulating foam, commonly expanded
polystyrene (EPS)
 Advantages:
a. Energy Efficiency - ICF has a low U-value, approx. 0.25
W/mk on average but can be lower.
b. Strong - High thermal mass provides structural strength.
c. Speed of Construction - A standard home can be
constructed to wall plate in 5 days

12.  Material : Expanded
polystyrene(EPS)
 Advantages:
 Faster, more efficient single
leaf construction can be used,
creating additional internal
space with improved thermal
performance.
 Lightweight materials make
this system suitable for tall
constructions.
 Unique thermal properties
EPS is 98% air, therefore it is
an excellent thermal insulator.

13.  Material: Polyester fiber
 Description: Manufactured from recycled
polyethylene terephthalate PET (plastic) bottles, and
being itself 100% recyclable.
 Advantages:
a. Made from recycled plastic - reducing landfill.
b. Does Not Shrink or effected by moisture.
c. Its contribute to both the thermal and acoustic
comfort of building occupants.

15.  PEX is a light-weight, flexible
pipe that is manufactured from
100% virgin high-density
polyethylene (HDPE) with cross-
linked polymer bonds.
 Advantages:
 easy to install when compared
to copper or CPVC, keeping
down labor costs.
 low material cost and low
operational cost.
 Reduced creep

16.  Rainwater harvesting
system
 Description: All
components are made from
plastics such as HDPE
including tanks, pipe and
gutter.
 Advantages:
 Reduce water bills.
 Alleviate demand on
municipal systems
 For landscape, using
rainwater to irrigate will
reduce fertilizer use.

17.  Material used: Concrete slab reinforced with GFRP
(Glass Fiber Reinforced Plastic)
 Description: The GFRP bars are manufactured by
pultration of E-glass continuous fibers and
thermosetting polyester resin.
 Advantages:
 Lightweight
 A very high strength to weight ratio
 Resists salt water, chemicals and the environment –
unaffected by acid rain, salts and most chemicals
 Non-corrosive

18.  Corrosion protection on GFRP is integral and
consistent throughout the bar.
 The ends can be cut and do not require
repair
 Build up of corrosion products in steel
cause more extensive cracking over time
 Eventually, concrete breaks away from
the bar

19.  Material used: Extruded polystyrene (XPS)
 Description: A material with uniformly small closed
cells and smooth skin; made by mixing polystyrene
pellets with various ingredients to liquefy them
 Advantages:
 Exhibits high compressive strength
 Natural resistance to rain and water vapor
 Low susceptibility to rot, mould and fungal growth
 Recycling – can be put back into the manufacturing
process for reuse

20.  Material used: Homogenous Vinyl Composition Tile (VCT)
 Description: Made from PVC Co-Polymer Resin, Filler,
Plasticizer, Stabilizer, Pigment and other additive
materials
 Advantages:
 Plastic flooring can be made to look however chosen to fit in
with homes decor
 Relatively inexpensive
 Easy installation – Costs less to fit
 Noise reduction – Very soft and therefore it does not make
much noise despite a lot of foot traffic

22. 1. Vapour control layer
(VCL/slipsheet): Protects
floor finish from moisture
produced by the concrete
slab during drying out
process
2. Floor finishes: Vinyl
composition floor tile
(VCT)
3. Insulating board: Extruded
polystyrene (XPS)
4. DMP: Damp Proof
Membrane to protect the
structure from ingress of
moisture
5. Concrete Slab: Reinforced
with GFRP
6. Hardcore layer: Gravel
layer

23.  Material used: PVC panels with tongue and groove
system
 Description: Polyvinyl chloride is a synthetic resin
made from the polymerization of vinyl chloride
 Advantages:
 Quick and simple installation
 Waterproof – ideal for “wet” areas such as bathrooms and
shower areas as well as many exterior uses
 Mould resistant – No more unsightly patches and build up
of mould
 Cheaper – Significant savings over traditional materials

24.  Material used: uPVC
 Description: A chemical compound of chlorine, carbon
and hydrogen. The “u” stands for unplasticized and
means that the material has not been softened by the
addition of plasticizers
 Advantages:
 Does not rot or biologically decompose
 Is resistant to weathering with low maintenance
requirements
 Is tough on impact
 Retains its shape within normal climatic temperatures

26.  All windows are installed with Low Emissivity Coated Glass.
 Low E-Glass is chosen to compliment the uPVC window
system because of its high reflection and low absorption of
infrared heat.
 This will give a good performance in thermal insulation.

27.  The plastic materials used can be re-shaped
at high temperature and can therefore be re-
used and recycled – leads to sustainable
building construction
 Plastics contribute to increasing the
efficiency of buildings
 Plastics save resources through:
 Cost-effective production
 Ease of installation
 Long life-span

28.  Plastics are capable of replacing many of the
conventional construction materials
 The principal advantages of plastics lie in their:
a) Low specific gravity
b) Moldability
c) Aesthetic qualities
d) Low cost
e) Electrical insulation
f) Thermal insulation
g) Simplicity in fabrication
h) Easy adaptability
