1. INTRODUCTION
Using my final Design Studio project as a base for this assignment, applications of building service
systems will be implemented onto a selected block of the clustered typology. Systems such as
electrical supply system, cold and hot water system, sewerage and sanitary system, and
rainwater/surface water drainage system are considered and applied into a primary school.

2. ELECTRICAL SUPPLY SYSTEM
Electrical by Laws – Electrical Supply Act 1997 (Act-477) PU(A) 38/94 Electricity Regulations 1994
Regulation 15 – Apparatus, conductor, accessories, etc.
• Any conductor or apparatus that is exposed to weather, water, corrosion under heating or
used in inflammation surroundings or in an explosive atmosphere shall be conducted or
protected in such a manner as to prevent danger.
Regulation 16 – Switch, switch fuse, fuse switch, circuit breaker, contractor, fuse, etc.
• Fuse and circuit breaker are arranged in such a manner as to break the current when it
exceeds a given value of sufficient time to prevent danger as well as to prevent danger or
over heating.
Components:
Electric meter
• Installed and monitored by TNB (Tenaga Nasional Berhad)
• Normally mounted at the gate pillar of a building where it is visible for monitor purpose
Distribution board
• Installed indoors of a building
• Electricity supply system divides electrical leaf into subsidiary circuits
Single switched socket
• Mounted on the wall where a plug can be conveniently inserted
• Normally a single socket outlet is rated 13amps
Two gang light switch
• Contains final distribution points of electrical system
• Serves appliances such as lighting, fan, etc
In Malaysia, the sole provider for electricity supply is TNB (Tenaga Nasional Berhad) which mainly
uses coal, oil and gas to generate the electrical power. There are power plants which are also
generated by hydropower (water) and biomass.

3. WATER SUPPLY SYSTEM
UBBL 1984 Section 84 – Prevention of Dampness
• Suitable measures shall be taken to prevent the penetration of dampness and moisture into
a building.
UBBL 1984 Section 89 – Chases
• Chase is made in wait for pipes and other facilities. It should not be less than 100 millimetres
thick on external walls and not less than 100 millimetres thick in a party wall and shall not be
wider than 200 millimetres.
UBBL 1984 Section 123 – Pipes and Service Conducts
• Allow adequate accommodation for pipes, stop cock and crossings for repair.
Valves should be placed at various points for the easy repair and inspection. Water tanks should be
placed at the highest point thus water can be supplied through gravity without the use of water
pumps. Overflow pipes are used to discharge surplus liquid from tanks for easy repair work as well.
Components:
Water Meter
• Measure the volume of water used by residential and commercial building that are supplied
with water by a public water
Gate valve
• Permit or prevent the flow of water which saves energy and reduces total cost of ownership
Stop valve
• Stop cocks at multiple fittings allow for easy maintenance and repairs
• Controls flow of water through pipes
Water heater
• Uses thermodynamic process by using an energy source to heat water above its initial
temperature
Copper tubbing
• Chanel hot water where its surface can withstand impact and abrasion

4. SEWERAGE AND SANITARY SYSTEM
Law of Malaysia Act 133 Street, Drainage Building Act 1974
Under laws of Malaysia Act 133, the installation and design of the sanitary pipe is safe, so that the
disposal of waste can be directed out of the premises safely without threatening the health of
occupants.
Vent openings should be 900mm above to avoid stain and ease of expulsion.
Section 56 – Rainwater pipes not to be used as soil pipes
• No pipes used for the carrying off of rain water from any roof shall be used for the purpose
of carrying off the soil or drainage from any privy or water-closet or any sulfage water.
Section 57 – Water pipes, etc, not to be used as ventilating shafts
• No water pipe, stack pipe or down spout used for conveying surface water from any
premises shall be used or to be permitted to serve or act as ventilating shaft to any drain or
sewer.
Section 61 – Ventilating pipes to sewer
• The local authority may erect or fix to any building such pipes as are necessary for the
proper ventilation of the drains and sewers belonging to it.
Function specific pipes such as waste pipe, soil pipe and ventilating shaft are used to ensure the
efficiency and sanitary of the building. UPVC pipes are used for soil pipe while vent pipe is used for
sewer pipe and waste pipe due to its durability and cost efficiency to other materials.
Components :-
Manhole
• The top opening of an underground utility vault
• Access point for making connections, inspection, valve adjustments and underground
maintenance work
Sump
• Low space that collects undesirable liquids such as waste water or chemicals
• Alternative usage of an infiltration basin to manage surface runoff water and recharge
underground aquifiers
Gully Trap
• Usually connected to the nearest building where foul gases from sewer will not transfer into
the house
• Constructed outside a building to carry waste water discharge from wash basin, bathroom,
etc
Vent cowl

9. AUSSIE KIMBERLY ANN 7
• Used as protection against seater spray and rain
• Regulates air pressure to ensure smooth flow of waste
• Eliminate foul smelling air to surroundings without disrupting comfort of people on lower
ground
• Can be turned upwards for easy maintenance and inspection
UPVC pipe
• Suitable in carrying waste due to its long lasting and durable properties
VCP pipe
• Vitrified clay pipe
• Made of a blend of clay and shale, resulting in an inert, hard, ceramic with long lifespan
Combined system

5. RAINWATER AND SURFACE WATER DRAINAGE MANAGEMENT
UBBL 1984 Section 115 – Roof coverings and drainage
• All roofs of buildings shall be so constructed as to drain effectually to suitable and sufficient
channels, gutters, chutes or troughs which shall be provided in accordance with the
requirements of these By-Laws for receiving and conveying all water which may fall on and
from the roof.
Law of Malaysia Act 133 Street, Drainage Building Act 1972 – Section 56
• Rainwater pipes not to be used as soil pipe state that “No pipes used in the carrying of
rainwater from any roof shall be used for the purpose of carrying off soil and drainage from
any privy or water closet or sullage water.
uPVC is used for vent pipes and soil pipes due to its durability and cost efficiency compared to other
materials. A separate drainage system therefore is used to prevent overloading problems.
Components-
Gutter
• Installed on the eaves of the roof to collect rainwater from the roof
• Diverts rainwater away from rainwater downpipe to the drain
Rainwater Downpipe
• Normally vertical and extends to ground level
• Rainwater is directed away from the building’s foundation to protect it from water drainage
• Usually piped to a sewer or let into the ground

6. CONCLUSION
Overall, this project has opened my eyes to a better understanding and knowledge of building
systems in design of a building, especially a school, since it incorporated my final Design Studio
building. I learnt to choose suitable systems for a clustered typology building and overcome issues
where certain building services systems were not as suitable.
