Introduction
Project 2 is an individual assignment on application of basic building
services. This is an individual project to apply building services systems to
a domestic sized building. This exercise requires students to demonstrate
their understanding on the application by producing technical drawings
incorporating the necessary building services.
Objectives of Project
The objectives of this project are as follows:
1) To develop the students’ understanding and knowledge of building
services systems in design and construction.
2) To apply appropriate building services system and solution for a
specific design.
3) To demonstrate a comprehensive understanding of applicability of
specific building services systems in the design in response to
practical considerations.
4) To develop students’ ability to resolve issues related to specific
building services systems.

ELECTRICAL SUPPLY SYSTEM
Introduction:
Electricity can be generated through various means:
 Oil, Gas, Coal Fired Power Plant
 Nuclear Power Plant
 Wind Turbine Power Plant
 Hydroelectric Power Plant
 Solar Power Plant
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
ELECTRICAL COMPONENTS
Kilowatt – hour meter
This meter is installed outside and monitored by Tenaga Nasional Berhad. It measures
the amount of electricity used by each household.

5. 5 | P a g e
Distribution board
Installed indoors and divides electrical power into subsidiary circuits.
Two gang switch
Final distribution point to surrounding appliances
Power socket
Provide electrical current to the appliances that are inserted

6. 6 | P a g e
Ceiling fan
The slightly angled blades of a ceiling fan turn counterclockwise to move air down,
making people feel cooler due to a concept known as the wind chill effect.
Air conditioning
Functions differently from a fan whereby it blows cold air into room thus removing hot air
and regulates temperature.
Air curtain/door
An air door or air curtain is a device used to prevent air or contaminants from moving
from one open space to another. The most common use is a downward-facing blower
fan mounted over an entrance to a building, or an opening between two spaces
conditioned at different temperatures

COLD WATER AND HOT WATER SUPPLY
SYSTEM
Introduction:
Water supply is the provision of water by public utilities commercial organizations,
community endeavors or by individuals, usually via a system of pumps and pipes.
These pipe carries water from the water source, street main or to the building and to
various points in the building at which water is used.
Cold water system provide:
 Drinking purpose
 Cooking purpose
 Sanitary purpose
 Washing purpose
 Gardening
Syarikat Bekalan Air Selangor Sdn Bhd (SYABAS), a member of the Air Selangor
Group, (English: Selangor Water Supply Company) is a water supply company
responsible for serving the state of Selangor and the federal territories of Kuala Lumpur
and Putrajaya in Malaysia.

WATER SUPPLY COMPONENTS
Stop valve
Controls the flow of water through pipe
and located at multiple fittings for easy
maintenance and repair.
Gate valve
Permit and prevents the flow of water to
save energy and reduce total cost of
ownership.
Water heater
Used for water heating which is a
thermodynamic process that uses
electrical energy to heat up the water
temperature.
Water tank

and stores water before distributing.
UPVC pipe
Unplasticized polyvinyl chloride is a kind
of pipe that is more durable and does
not bend which is safer for distributing of
water.
Copper pipe
Lightweight, durable, resistant to
corrosion and mainly for carrying hot
water due to higher heat capacity.

Washroom sink
For washing hand and other purposes.
Water mixer tape to supply hot and cold
water.
LEGEND OF WATER SUPPLY
COMPONENT
Flush toilet
Dispose human solid and liquid waste
by flushing out with water down the
drain pipe.

Uniform Building By Law (UBBL)
Section 84: Prevention of Dampness
Suitable measures shall be taken to prevent the penetration of dampness and moisture
into the building.
Section 89: Chase
Chase is made in wall for pipes and other service facilities. It should not be less than
100 mm thick in external walls and not less than 100 mm in party wall and shall not be
wider than 200 mm.
Section 123: Pipes and Service Ducts
Where ducts or enclosures are provided in any building to accommodate pipes, cables
or conduits the dimension of such duct or enclosures shall be
(a) Adequate for the accommodation of the pipes, cables or conduits and for the
crossings of branches and mains together with supports and fixing; and
(b) Sufficiently large to permit access to cleaning eye, stop cocks and other controls
there to enable repairs, extensions and modifications to be made to each or all of the
services.

SEWERAGE AND SANITARY SYSTEM
Introduction:
 Wastewater - unsanitary liquid discharge from residential, commercial and
industrial areas.
 Originate from toilet, bathroom, sink and such in buildings.
 Wastewater can also called SEWAGE.
IWK (Indah Water Konsortium) is mainly responsible for operating and maintaining the
public sewage treatment plants and network of underground sewerage pipelines.
SEWERAGE AND SANITARY COMPONENT
Floor trap
Has its own trap to allow water to flow through the sewerage
pipe and travel to the manhole. Can be remove manually,
usually made of cast iron or uPVC.
Manhole
An opening to an underground utility vault used to house an
access point for making sewer connection and inspection if
there is a blockage.

14. 14 | P a g e
Drain sump
A lower space that intercept and collect waste liquid from sinks
and bathroom that may contain chemical or harmful substance. It
acts like an infiltration basin, managing surface runoff water.
Vent cowl
Connected to the manhole, helps remove odor and releases it to
open air.
Gully trap
Usually constructed outside of a building, it carries water waste
from kitchen sinks and connects the stream to the nearest sewer
pipe.

RAINWATER DRAINAGE SYSTEM
Introduction:
Water from the rain is collected by drainage along streets or buildings, rain water may
carry soil, pet waste, oil, pesticides, and other pollutants with it. This polluted runoff may
travel into streams or lakes untreated. The rainwater drainage system admits and
convey untreated rainwater into sewer system.
RAINWATER DRAINAGE COMPONENT
Gutter
Installed at the edge of the roof, it is a narrow duct that
collect rainwater from the roof and divert it to a
downpipe and into the drain
Rainwater downpipe
Connected from the gutter to the ground, it directs
water collected from the roof gutter to the ground
perimeter drain and discharged away from the building
to prevent water damaged of the foundation.
Perimeter drain and apron
Situated around the building’s perimeter, it is a
trenched pavement, act as a pipe that helps redirect
water to the nearest drain. The concrete apron gives
the building a step back so the building has some
protection against sunlight and rainwater.

All roof 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-Law for receiving and conveying all water which may
fall on and from the roof.
