ABSTRACT
Building services plays a big role in any building. It is to elaborate and implement the
functions of a building, how they are operated, comfort along with safety of
occupants. This report basically contains the case study of building services in
Summit USJ, which includes the different type of systems used in the building and
the purpose of the building. From the case study, the types of system used are
identified, the problems in the existing building is analyzed, and suitable
recommendation are given to further improve the building services of the building are
given based on Uniform Building By-Laws 1984 (UBBL). The report covers the topic
of building services such as fire protection system, mechanical and air conditioning
system, vertical transportation system and electrical supply system in the Summit
USJ.

1.0 Introduction
Our group members are Lee Kim Thiam, Liew Yong Sheng, Wong Geng Sen,
Muhammad Hasif, Kevin Lee, Goh Jeng Jhieh and Lee Pui Sun. For this assignment,
we chose Summit USJ as our case study location. We were requested to observe
and comment on the existing building service systems in our building of choice. First
off, Summit USJ is a huge building that consists of a six storey shopping centre as
well as a hotel. All six stories are retailed and there are seven storeys of parking
space including underground parking. We were only able to access the area within
the shopping centre premises as the area on the higher levels were out of
boundaries due to renovation purposes.
Figure 1: Summit USJ

1.1 Reason of Case Study Choice
Being one of the oldest developed mall in USJ, Summit was completed in
1998. Since the ending of its construction, its popularity has risen to a peak of
the summit. However, as years gone by to this day, its attractiveness has
dropped significantly to a point where its existence is not heard of by many.
So why is this happening? Before we start off, we will need to first analyse the
surrounding of Summit USJ. Summit USJ, along with Summit Hotel, is placed
strategically in the commercial area of USJ. While it is placed beside Segi
College and Da Me, it is also accompanied by other high-rise development
including MenaraHeltechVillage, Impian Meridian, Casa Subang and USJ
Sentral.
Summit USJ mall is a 6 storey shopping mall with retail space of 599,474 sf.
The Summit provides facility such as free centralized air-conditioning during
office hours, 24 hour security, CCTV and covered basement parking bays.
Within it, shoppers have multiple selection of restaurant, fashion, tech-shops
and could even enjoy watching movie in their Golden Screen Cinema.
However, the problem lies not in the lack of variety of shops in Summit USJ;
it’s the poor management of building service in the building that unconsciously
rejects the shoppers.
In this report, we will focus on the discussion regarding the utilization of Fire
Protection System and Air-Conditioning System in Summit USJ mall as well
as its problem and our recommendation to fix the problem.

7. 5
2.0 Existing Types of System
2.1 Mechanical and Air-conditioning System
Mechanical and Air-conditioning system is a process where air in an enclosed space
is constantly replaced with fresh air. Extraction or supply of air can be carried through
either mechanical or natural ventilation. The main purpose of-ventilation is to control
the temperature, moisture and air circulation as well as maintain the freshness of the
indoor air. Due to the hot climate that Malaysia has to offer, ventilation is vital in
keeping both the building and its occupants cool. For Summit USJ, we will be
focusing on Mechanical Ventilation.
2.2 Ducting System
For every floor, the ceiling is exposed, showing that the building is built in with the
centralized system. Chilled air is sent throughout various parts of the building from
the AHU room through the ducting.
The ducting system in the building is insulated to reduce installation cost and heat
loss. The ducts are designed to provide equal air velocity within the system. This is to
ensure that air in every area of the shopping mall is evenly distributed.
Figure 2: Ducting system in the building.

8. 6
2.3Centralized System Components
1) Cooling Tower
For centralized system air conditioning, there is a cooling tower which is used to cool
the water used for the cooling coil by expelling the heat from the chilled water taken
from the rooms.
Figure 4: Extraction ventilation system in the building.
Figure 3: Details of cooling tower.

9. 7
2.4 AHU Room
The Air Handling Unit (AHU) Room is a plant room where it circulates the air. AHU
connects to the ductwork that distributes the conditioned air throughout the building
and the warm air is returned to the AHU room to be cooled after going through the
cooling coil and filter. The chilled water from the cooling coil in the cooling tower is
supplied and returned in grey pipes.
2.5 Diffusers
Other components of the centralized system can also be seen throughout the
building like supply air diffuser and the return air diffuser. Supply diffusers are used
to discharge chilled air from AHU rooms through ducts while return air diffusers are
used to return warmer air back to the AHU room to be chilled and supplied once
more.
2.6 Supply Diffuser
As stated therein, Supply Diffusers are used to discharge air to rooms, where
different types are used according to the area, space or the ceiling of the room in
order to sufficiently diffuse air by discharging it in different directions or speed. There
are many types of diffusers that are used in Summit USJ.
One of which is the cone diffuser, which can be seen next to the parallel escalator
area, where the ceiling is voided in order for the escalator to be placed. The cone
diffuser, which can be raised or lowered, is used to cool the space of the escalators
for the user’s comfort.
For the suspended ceiling, the 4-way diffuser seen in Figure 8 & 9 is typically used in
various parts of the building such as the lower ground floor. This type of diffuser is
typically used in many buildings as it discharges chilled air in 4 directions, hence
spreading the air around the space efficiently.

10. 8
For the exposed ceiling, there are two types of supply diffusers, one of which is seen
to be straight from the ducting and another type is the multi-direction diffuser as seen
in Figure 11. The design of the ducting, which reduces the size of the ducting, allows
the same volume of air to be discharged at every opening.
Figure 5: Cone diffusers
in the building.

2.7 Electrical Supply System
2.8 Distribution Panels
Distribution panel distributes power to the consuming loads. The function of
distribution panel as an assembly of switches and circuit protection devices that
serve final distribution point.
Figure 8
Figure 9: Distribution panel details

12. 10
A distribution panel consists of circuit breakers and busb ars. Circuit breakers
functions in the same way as what a fuse does in a plug, mainly to cut off the power
supply when it is overloaded. Circuit breakers protect for high current supply and
feeders power supply. It must remain in a closed connection when occurrence of
short-circuit arises. It enables the downstream circuit breaker cut off the faults.
Moreover, switchboards also contain a set of busbars which is used to transmit high
electrical current in a distribution panel. Busbars connect to switchgear to clear faults
and de-energize equipment.
2.9 Electrical Conduit Tee
Conduit prevents the cable from physical damage and offers insulation to heat.
Conduit tee fitting also provides continuous support. PVC electrical conduit is rigid
and lightweight. It is also durable and readily cut.
Figure 10: Electrical conduit tee with wires.

13. 11
2.10 Main Switchboard Room
Main switchboard is an assembly of switches and circuit-protection devices where
electricity supply is distributed. It is considered low voltage as the current has been
stepped down. It transmits electricity from one source to another.
2.11 Transformers Room
Transformer room is where the step-down transformers are placed. A transformer is
a machine used to step down high voltage current to a lower voltage current. The
step down current will then be transferred to the main switchboard for distribution and
supply in a building. A “DANGER” sign board is labeled to create awareness to the
people who is nearby.
Figure 11: Main Switchboard Room

14. 12
2.12 Meter Room
The electricity meter room consists of many electricity meters. Electricity meter is a
device that measures the amount of electric energy consumed by Summit USJ.
Normally, electric meter is typically calibrated in billing units which also known as
kilowatt hour (kWh).
Figure 12: Electricity Meter Room

15. 13
2.13 Fire Protection System
Fire protection is the measures taken to prevent fire from becoming destructive,
reduced the impact of uncontrolled fire and most importantly to save life and
property. Oxygen, fuel and heat are the 3 main factors to an occurrence of fire event.
Fire protection methods are subdivided into two, which are active fire protection
method and passive fire protection method.
2.14 Active Fire Protection Method
Active fire protection methods require mechanical, electric or electronic activation. It
consists of manual or automatic fire protection systems such as fire alarms, heat and
smoke detectors, wet and dry risers, hose reels and carbon dioxide fixed installation.
2.15 Fire Extinguisher
Fire extinguishers are intended to extinguish small scale of fire to prevent the
escalation of fire into full-scale fire before the fire department arrives. Fire
extinguishers are placed in a prominent location that can be easily spotted, near
room exits, corridors, stairway and landings. Also, it should be placed within
recessed closets to prevent obstruction and not more than 20 m from a potential fire
hazard.
2.16 Wet Riser
Wet riser is constantly filled with water. The water supply shall be capable of
maintaining a running pressure of 410 kPa at the highest landing valve and given a
flow rate of 2.3litre/second. Wet riser is used in the Summit USJ because the height
of the building is more than 30.5m but less than 70.5m. Based on our observation of
the entire building and the existence of wet riser, we can assume that the building is
more than 30.5m but lesser than 70.5m, fitting the requirement of wet riser.

16. 14
Figure 14: Wet Riser Room
Figure 15 Sprinkle Piping
Figure 16 Hose Reel
2.17 Sprinkler System
The sprinkler system is to detect, control, and extinguish a fire and also to warn the
occupants when there is an occurrence of fire. It is an automatic fire suppression
system, which uses a range of designed pipework fixed inside the building and water
as the fire-fighting agent. The water is not contained inside the pipe. The sprinkler
system consists of the fire pumps, water storage tanks, control valve set, sprinkle
heads, flow switches, pipework and valves.

17. 15
Figure 17 Sprinkle Head
The sprinkle head consist of a plug held in place by a glass bulb filled with a glycerin-
based liquid that expands, it will become fatigue when expose to temperature of 57-
105 degree Celsius. The liquid is designed to expand and break the tube at a certain
temperature. The plug is forced out by the pressurized water behind it and deflected
away by a beveled edge and the water sprays over the deflector plate in an even
pattern. Water will then continue to flow until the main valve is switched off.

18. 16
2.18 Fire Alarm System
The fire alarm system is designed to provide warning of the outbreak of fire. The fire
alarm panel is designed to monitor each circuit, zone or point of any condition display
the status of that condition and to operate any required output.
Figure 18 Fire Control Panel
2.19 Fireman Switch
The fireman switch is designed to turn off the neon lighting or other hazardous
electrical equipment in case of fire. This is to prevent the equipment from overheated
and results in explosion.
Figure 19 Fireman Switch

19. 17
2.20 Manual Call Point
The manual call point is the device that enables personnel to raise an alarm
manually once verification of fire has been confirmed. The manual call point should
be installed at the height of 1.2m above floor. It is commonly found at exit routes,
entry of floor landings of staircases and at all exits of open air. Its coverage range
should be within a distance of 30m.
Figure 20 Manual Call Point Connected to Alarm Bell
Figure 21 Fire Alarm Bell
When smoke is obstructing the light from passing through the photoelectric cell in a
smoke detector, the fire alarm bell will be triggered to warn and give signal for the
occupants to escape.

20. 18
2.21 Passive Fire Protection Method
Passive fire protection method is an integral component of the structural fire
protection and fire safety in a building. It attempts to slow down the spread of fire
through the use of fire resistant wall, floors and doors. It also protects the important
structure such as load bearing columns and beams from collapsing prematurely
during fire.
2.22 Fire Escape Route
Fire escape route is an emergency exit that usually located at the end of a building
where the occupants can evacuate easily. It can be occasionally inside but is
separated from the main areas of the building.
Figure 22 Fire
Escape Plan
The fire escape staircase of Summit USJ is considered ideal and fulfilled the needs
of the UBBL 168 part 8, where the treads of the staircase are more than 255mm and
the riser is less than 180mm. The numbers of risers per flights at the escape
staircase not exceeding 12 risers. There are also no winders in the escape staircase
of the mall.

21. 19
2.23 Fireman Lift
Fireman lifts must be provided to allow firemen to reach any floor when there is an
outbreak of fire in the building. The lift car should have a minimum internal dimension
of 1.1m, a net internal floor area of not less than 1.35m2
and rated load of not less
than 680kg.
2.24 Compartmentation
The building is sub-divided into compartment with the
implication of fire resistant wall and floor. Insulation for
a period should not be less than 15 minutes. The door
uses the automatic door closers which is the hydraulic
spring operated lever.

The use of electrical traction elevators which are driven by AC or DC electric
motors are the most common type used in a building. The principle of a traction
elevator is essentially a box on steel ropes that are looped around sheaves
connected to an electric motor. The sheaves have a counterweight attached at their
end to balance the load of the elevator car. Traction on the ropes raises and lowers
the elevator. The nowadays series of traction elevators are mostly without machine
room as it have more advantages such way but for its old background, its common
for it to have a machine room.
This type of elevator, provide better speed and smoother travels and suitable to
be installed in a high rise building or the modern building which peak hours are
usually most of the time. Plus, it is energy efficient as counter weight balances the
load. However, both initial and maintenance cost are high as the necessary of
installing a machine room. Getting to the machine room itself is hard because of its
being located in the shaft headroom.
For both product, the sensor system used mechanical door bumpers, a sensor that
prevents the doors closes when a person or an object blocks the doorway. These are
common in older elevators and specifically installed in Asia. However, nowadays,
most companies have stop using these as its occasionally malfunction and do not
retract when a passenger bumps or hits them.

24. 22
The positions of the elevators have its own purpose. Based on our observation,
Product B, which are still usable are placed near cargo and goods shipment, and
Product A, the continuously broken elevator are placed according to UBBL. The
elevators are more convenient than their escalator as their placements are close to
attraction shops and Summit’s office level.
Figure: 27: Elevator Sensor

25. 23
2.27 Escalator
Escalator is a moving staircase, a conveyor transport device for carrying people
between floors of a building. By simple observation and understanding, its a device
that consist of:
 Motor-driven chain of individual,
 Linked steps that move up or down on tracks
 Allowing the step treads to remain horizontal.
Most commercial or high rise building commonly used more than one type of
escalator and a travolator. In the Summit Mall, the placement of the escalators are
nearly the same as the Sunway Pyramid’s.
Type Used :
a) One Way Traffic
b) Two way Traffic (Parallel)
c) Travolator

26. 24
One way traffic that they installed cover 4 floors both on west and east side of the
mall, where at the middle north side of the mall, the two way traffic only covered 3
floor. The difference is that the first type i connected to the underground level while
the second type did not. The reasons would be business wise, as the use of one way
traffic reduced the length of area used to construct an escalator. Thus, it allowed the
mall to provide more business space on the underground level as it is one of the
most attractive for being the mall’s food court.
Figure 28: One Way Escalator (top)
Figure 29: Two Way Escalator (right)

27. 25
The usage of travolator is common in every mall. It is a slow moving conveyor
mechanism that transports people across a horizontal or inclined plane over a short
to medium distance. Moving walkways can be used by standing or walking on them.
Travolator usually connect the lowest commercial level to the car park area or
basement levels. It gives more space for them to travel from one floor to another if
they need to carry a lot of items. Plus, it is more convenient when placed next to a
groceries store. Giant’s Hypermarket took that advantage.
The distance between one escalator to another is quite far, and getting from one
area to area will took an unusual amount of time, thus making elevator a more
convenient device to be use. Plus, with the additional of blocking steel stand on the
landing section, it prevent stroller, troller from using such device.
However, it is a good idea to use a multiple or two way path for type A, as it reduced
the time need for a user to go up and down between 2 floors.
The sensors embedded in the Handrail Inlet Cap detect passengers and control
Automatic Operation. The escalator operates at a low speed in stand-by, and
gradually increases speed to the rated speed after detecting a passenger
approaching the boarding area. This is called Post-Free Automatic Operation, it
allowed the escalator to be energy efficient and avoid the use of post sensor which
will take more space and can be easily malfunction or broken.

3.0 Recommendation and Justification
3.1 Recommendation for air ventilation
When we were researching around the building,
we found that the AHU room can be easily
breached without being locked for safety.
It is dangerous for AHU room to be unlocked,
since this room is used to control the air
conditioning by providing clean air to the
customers. Clean and fresh cool air has to be
generated from the AHU room; therefore any
suspicious act that can damage the AHU will
bring toxic air or gas to customers, or even
having to suffocate in the building. So it is
important and recommended to lock the room
from preventing incidents happen.
Besides that, the AHU room is not organized as it should be. It is dusty and
dirty when we took a quick look into the room. Materials were scattered everywhere
and the surrounding was unsightly to be seen. When the room is full of dust while the
air conditioning is running, worse case can be predicted as the air flowing from the
diffusers may be dirty and hard to breathe. To ensure the safety and health of
everyone in the building, recommendation of cleaning and tidying the AHU room can
be made.
Figure 32 AHU Room
Figure 33: Unlocked Door

29. 27
As for this outdoor kitchen exhaust vent, it can be seen that it is being dent very
badly and it is not attached to the air hole from the wall. Food that is being cooked
from the kitchen needs to be in the upmost clean environment as it is served to
customers numerous times a day. As for health concerns, birds for example pigeons
or hawks are always seen around the area. If they are to be staying inside the duct or
in the worst case scenario, bird poop is very hazardous to the health of human
beings.
In this AHU room (compared to figure 25), the filter is much more torn and misplaced.
Due to this misplacement, dirt and unwanted gas substance will easily flow through
gaps and tears. While its effect has yet to show over the years due to the lack of
severity, it may trigger allergy and uncomfortability. Not only that, this explains the
horrible stench coming out from the specific area. From this, we can assume that the
horrible stench coming out of the air condition in that specific zone are due to the
misplacement and tears of the filter in the AHU room.
Figure 34: Ducting
Figure 35. AHU Room (upper
floor)

30. 28
Modern air conditioner’s condenser are white while the one before are usually green.
From the image, we can deduce that Summit is still using old condenser to keep the
building cold. While it doesn’t create problem, it does decrease efficiency and
wastage of energy. This is because researchers have researched and develop
condenser that are more and more efficient and less energy wastage.
The problem created does not affect customers (unless Summit USJ decided to
increase the tax on shops which lead to increase in prices), it affects Summit USJ in
a sense that higher cost needs to be paid despite producing equivalent, if not lesser
than modern condenser Summit USJ have.
The proposal to this issue is simple; Change the condenser. Of course, the initial
cost would be higher but to think about it on the long run. It will definitely save a lot of
energy and ultimately cost. Meaning, it’s definitely a worthwhile investment.
Figure 36: Old Condenser

31. 29
3.2 Recommendation for Fire Protection System :
While it is not stated by the Uniform Build-By Law that the lift needs to have a sign
noticeable for fire fighter and victim to fire. We suggest it is better for the building to
have at least a more visible signs around that are noticeable to the eye instead of a
“Lif Bomba” placed on top of the elevator.
This is important in a sense that during a fire, field of vision is narrowed down
because of the smoke induced by the fire and thus it is more advisable to have a
bigger, noticeable sign. The law was enacted in Hong Kong’s Uniform Build-By Law
which we find the fact useful in this case. We hoped to see Malaysia’s Uniform Build-
by Law would enforce the same.
Figure 37: Fire Lift

32. 30
The manual call point of the building, majority of
them, have broken lock. With simply one finger,
one of our teammate manages to open it without
problem. From closer inspection, we noticed that
the cover was bent.
Not only does this risk false alarm and uses
unnecessary resources only to realize there are no
fire to begin with, the manual call point may suffer
vandalism to a point where a call could not be
made. Imagine, if you will, that, during an event of
arson or accident, an authorized employee ran to the manual call point only to find
that the wire has been cut off because the vandals thought that it was hilarious to do
so and caused casualty that could have been avoided.
The recommendation for this service is not only ensuring the manual call point to be
locked and in shape, we also recommend them to enforce the security system to
ensure these fire protection systems are constantly protected from vandals.
As we continue our expedition, we found
more broken locks that are supposed to
be maintained. To further prove my point
that the facility is not thoroughly
managed, from the picture you can see
dust collecting on these systems even
without the need to zoom in.
Figure 38: Manual Call Point
Figure 39: Fire Hose
Figure 40: Dust Collected

33. 31
Here, you can see a fire extinguishing box is
completely empty. Are the customers, workers and property in SummitUSJ really
safe from a fiery scenario?
As we continue a bit further, we found the
door of AHU unlocked (as mentioned in
Recommendation for Mechanical
Ventilating System). So imagine that when
there’s a fire happening in the AHU room
where the electrical parts suffer short
circuits. As we know, electrical fire cannot
be extinguished with fire and should be extinguished with Carbon Dioxide. However,
as mentioned before there are no fire extinguisher in the fire extinguish box.
It is therefore important to ensure that the fire extinguisher box always have a fire
extinguisher inside and ensure that the box have a functional lock. We did not try the
lock because the security were nearby but we assume that the lock is malfunction
like the manual call point and the fire hose case.
Figure 41: Empty Fire Extinguishing Box
Figure 42: AHU Room

34. 32
Most fire alarm uses ‘break glass if fire’ system. Summit USJ used the same system
for the job. However, there is no glass to break for this system and is free for
anything or anyone to sound the alarm.
We suggest Summit USJ to use another type of alarm system that is reusable. Since
Summit USJ does not seem to have the time to constantly manage and replace the
glass of the fire alarm. It may be more advisable to use a lever type fire alarm. After
unlocking the alarm, the authority simply need to pull down the lever to sound the
alarm. The disadvantage of this is that it’s not available for everyone except authority
with the key but with the amount of broken utility in the area, we can conclude that
majority of ‘everyone’ are vandals and should not be trusted with these fire alarm.
Therefore, we came up with this suggestion.

4.0 Conclusion
We must always remember that a building rely on these services to provide a safe,
healthy and comfortable living and working environment. These facility and services
are necessary in providing comfort and safety, medically healthy, water and electrical
supply, protection from fire and improving productivity in workplace
In a nutshell, we are now aware that the failure to maintain the facility of a building
can change the overall perception towards it. Not only does it change the building
aesthetic visually, it also affects the overall feeling, comfortability and worst of all
security towards the building. True, not all building are perfect but when a building fail
to provide a sense of security by at least removing the dust of the fire protection
system.
What we suggest is that they should invest a little more to improve the facility of the
mall and create plans to maintain it. As mention before, it is important that the facility
are managed to create a better reputation. Recently, Summit USJ have been
suffering tons of malfunctioning of elevators and escalators to a point where it
creates frustration for customers because they would then have to search for a
longer road to reach somewhere they could have if they are not malfunctioning.
More importantly, we would also like to thank Summit USJ for being our model for
our study in building service. Not only did we learn observation skills, we also learn
how to analyse our observation, attempt to research and improve the situation.
