2.0 INTRODUCTION
SS15 Courtyard is a high rise commercial building that located in SS15, Subang Jaya. The mall
was developed by Titijaya Group and officially opened in December 2015. The main reason that
we choose this building as our case study is because this building consists of 2 office
towers( Southern & Northern ), a residential block(Northern) and a retail mall (3 floors).
Therefore, we can observe the different types of operation system in different area.
We visited SS15 Courtyard for twice. Our first visit was on 17st of May, Mr Chang had brought
us around the building to describe the function of each system. The second visit was on 1th of
June. Unfortunately, we could not visit the vertical transportation because Mr Chang rejected us
due to the private and confidential policy. However, we are really grateful that Mr Chang spent
his time on the guide and provide us the information.

2.0 Literature overview
Mechanical Ventilation
Mechanical ventilation is the process where the air in a space is being removed and replaced
with fresh air with the use of mechanical system such as powered fan and air conditioning. This
type of ventilation is needed when the natural air circulation is insufficient to provide fresh air to
the occupant in the area. It is an active design which used to control indoor air temperature and
quality, remove excess humidity, odors and contaminants.
Air Conditioning System
Air conditioner is one of the mechanical ventilation systems that can change the temperature of
the air within a building to provide thermal comfort for the occupants. Air conditioner is
commonly used in both domestic and commercial building. The operating principle of a
refrigeration cycle is to transport heat from the area to be cooled to the outside environment by
using a medium called refrigerant which absorbs and removes heat. The common types of air
conditioning system used nowadays are unitary system, package system and centralized
system.
UBBL Part III Section 41– Mechanical Ventilation and Air-Conditioning
1. Windows and openings allowing uninterrupted air passage is not necessary if the rooms
is equipped with mechanical ventilation or air- conditions.
2. In case of air- conditioning failure there should be alternative ways to introduce fresh air
into the room within half an hour.
3. This provision apply to building with mechanically ventilated or air- conditioning.
4. Windows and openings allowing uninterrupted air passage is no necessary if the toilets
are equipped with mechanical ventilation or air- conditioning.

2.1 Unitary System
There are two types of unitary systems: window unit and split unit. The split unit system is
chosen to use in the mall.
Split unit consists of two main parts:
1) Indoor unit:
It is a unit that produces the cooling effect inside the room or office. The indoor unit houses the
evaporator coil, a blower and the filter. After passing from the expansion coil, the chilled Freon
fluid enters the cooling coil. The blower sucks the hot, humid and filtered air from the room and
it blows it over the cooling coil. As the air passes over cooling coil its temperature drops and
also loses the excess moisture. The cool and dry air enters the room and maintains comfortable
conditions as per the requirements.

2) Outdoor unit:
This unit consists components such as compressor, condenser coil and expansion coil. This unit
is installed outside the room or office space which is to be cooled and the major source of noise
is eliminated.
In the outdoor unit, there is a fan that blows air over the condenser thus cooling the compressed
Freon gas in it. This gas passes through the expansion coil and gets converted into low
pressure, low temperature partial gas and partial liquid Freon fluid.
Indoor Units
There are two types of the split unit AC can be found in the mall are:
a. Wall Mounted Type:
This unit can be mounted in the room’s wall. It is suitable for a room or an area required
different power to fulfil in different air condition.
b. Ceiling Mounted Type:
This type is suitable in large open spaces to provide cooling comfort. Its four-direction
louvers and fan speed features on the ceiling cassette units allow for even air
distribution.

2.1.1 Components of Indoor Unit
The components in the unit are:
a. Evaporator coil:
A network of tubes filled with refrigerant that remove heat and moisture from the air as
the refrigerant evaporates into a gas again.
b. Air filters:
Air filter elements trap dust, pollen, and other particles as air moves through the air
conditioning system and helps to supplying clean air to the room.
c. Blower:
The blower sucks the hot and unclean air from the room and supplies cool and clean air
back.
d. Drain Pipe:
The pipe is often made of PVC, that carry the condensate water to the outside of the
building.
2.1.2 Components of Outdoor Unit
The outdoor unit is installed outside of a room or any open space for the ease of installation and
maintenance. The components in the unit are:
a. Compressor:
The electric pump, or heart of the system, that circulates the refrigerant in a closed loop
between the condenser and evaporator coils.
b. Condenser:
A network of tubes filled with refrigerant that remove heat from the heated gas
refrigerant and convert the refrigerant into a liquid form again. The excess heat escapes
into the outside air.
c. Cooling Fan:
It pulls the air through condenser coil for heat dispersal.
11. School of Architecture, Building and Design
Taylor’s University | Building Services II | “SS15 Courtyard, Subang Jaya”
10
d. Expansion Valve:
It is used to control the refrigerant flow in a refrigeration system. They help to facilitate
the change of higher pressure of liquid refrigerant in the condensing unit to lower
pressure gas refrigerant in the evaporator.
2.2 Package Air Conditioners System
A package unit is the all-in-one heating and cooling system. It is similar to split unit but it
provides greater capacity and efficiency. The unit is suitable for places like restaurants, small
halls, etc. Packaged AC can be either air-cooled or water-cooled.
The air-cooled packaged AC is another system used in mall. Tenants such as 7eleven,
Rakuzen, Guardian, etc. Referring to the site officer, the reason of their choosing is because
this system is greater for enhancement in cooling in small space.
In this system unit, the refrigeration coil is cooled by the atmospheric air. There is an outdoor
unit that comprises the components like the compressor, condenser and expansion valve. The
outdoor unit can be kept on any open space where free flow of the atmospheric air is available.
The fan located inside this unit sucks the outside air and blows it over the condenser coil cooling
it in the process. The condenser coil is made up of several turns of the copper tubing and it is
finned externally.
The cooling unit comprising of the expansion valve, evaporator, the air handling blower and the
filter are usually hanged to the ceiling. The ducts coming from the cooling unit are connected to
the various rooms that are to be cooled.

2.3 Centralized Air Conditioning System
Another air conditioning system utilizes in Courtyard is centralized air conditioning, it is suitable
for large building which comprised of several floors to be cooled down like shopping mall,
cinema, airport and hotel. It is more economically viable for a large building as it can cool the
whole building at once. It must be installed before the building done constructing. This system is
different from unitary and package system as there is no individual cooling coil and other
components like evaporator installed in the room, all the compressor, condenser, expansion
valve and evaporator are kept in a large plant room. Chilled air is supply to the building with a
system of supply and return ducts. This system consists of 3 main parts where the process of
heat exchange is carried out, namely AHU room, chiller room and cooling tower.
2.3.1 Air Handling Unit (AHU)
Air handling unit is a device used to regulate and circulate air as part of a heating, ventilating, air
conditioning (HVAC) system. Basically, AHU room consists of the supply duct for inlet and outlet
of air, blower, heating and cooling coil, filter compartment and air duct. AHU acts as an
intermediary which receive chilled air from chiller room and supply them to all the rooms. All the
unwanted heat is removed from the rooms by the inlet diffuser, subsequently it flows back to the
chiller room.

Taylor’s University | Building Services II | “SS15 Courtyard, Subang Jaya”
14
2.3.2 Chiller Room
2.3.3 Cooling Tower
Cooling tower which is normally located on top of a building is used to reject the heat from the
condenser water. Water is sprayed down onto a water basin to increase the water surface area
as large as possible. Simultaneously, there is a fan on top to blow the water. Heat is being
removed at the same time when a small amount of water is evaporated, creating a cooling
action. The cooled condenser water is then returned to the chiller unit.
Chiller unit is usually located at the basement
of a building. A chiller unit consists of four
major components, there are condenser,
compressor, expansion valve and evaporator.
This is the place where the exchange of heat
between the condenser and evaporator
happens. The heat from AHU room is returned
back to evaporator (chiller room). The
condenser water picks up the heat then
pumped up to the cooling tower for cooling.
The cooled condenser water is returned back
to chiller room, the whole process is repeated.

2.3.4 Air Handling Unit (AHU) room
There is a sign labelled ‘A.H.U room’ on each door of the room.
This is the internal part of the AHU, it consists of blower, heating and cooling coil. The blower
serves to circulate the air movement and control the airflow rate. The cooling coils are used to
cool down high temperature air whereas the heating coils serve to allow the low temperature
air to be heated up.

This is the filter panel that helps clean the air, ensure that a dust free and safe- inhaling air is
supplied to the building.
This is the ducting system in AHU room, its function is to transport air to and from the complex.
This allows the ideal temperature to be achieved and maintained in the building when the hot
and cold air mixed together. All the ducts are sealed, tested for tightness and insulated.

There are 2 pipes in the AHU room, one labelled with CHWS (dark blue in colour) and another
is CHWR (light blue in colour).
There is another component called humidifier in AHU room. It helps to keep the indoor
environment moist as excessive cooling will lead to dry atmosphere which can causes various
health issues.
2.3.5 Chiller Room
This is the chiller room located at level P4 (parking area) of ss15 Courtyard, there are a total of
3 chiller units. Two out of the three chiller units will take turn to operate everyday to expand their
service life span.

2.3.7 Diffuser (Inlet/Outlet)
Louver bladed diffuser
It is the most common diffusers in Courtyard. They are used to supply air at ceiling level.They
can deliver air in 360° which helps to distribute airflow evenly to a big size room. It has circular,
square and rectangular shapes. For the square shape diffuser, it has four separate quadrants to
allow air to flow in 4 directions.
Cone Diffuser
They can be seen on the wall above level 1 in Courtyard, it is used to when large air velocities
are needed at the high ceiling area (from ground level to level 1 in Courtyard). It can supply air

4.1 Active Fire System
Active fire protection is the component of fire detection and prevention which reacts to action or
motion. The role of active fire protection within the fire containment process is to detect, alert
about, and seek to eliminate the fire hazard.
4.1.1 Sprinkler System
A fire sprinkler system consist of water supply system, providing adequate pressure and flow
rate to a water distribution piping system, onto which fire sprinklers are connected. The plug is a
small glass bulb full of a glycerin-based liquid designed to expand and shatter when it gets hot.
If fire breaks out, the air temperature above the fire rises and the sprinkler activates when the air
temperature gets high enough. The sprinkler sprays water forcefully over the flames,
extinguishing them completely in most cases.

4.1.2 Fire Extinguisher
A fire extinguisher is used to extinguish or control small fires, often in emergency situations. It
located in the wet riser room. Typically, a fire extinguisher consists of a hand-held cylindrical
pressure vessel containing an agent which can be discharged to extinguish a fire. Cartridge
Operated Dry Chemical fire extinguishers extinguish the fire primarily by interrupting the
chemical reaction of the fire triangle. Like the stored pressure dry chemical extinguishers, the
multipurpose dry chemical is effective on Class A, B, and C fires.

4.1.3 Automatic CO2 System
It located in the electrical system control room. Carbon dioxide is a colorless, odorless,
electrically non-conductive gas that is highly efficient as a fire suppression agent. Gas
Suppression Systems are generally used in concealed rooms. The principle used by Gas
Suppression System is by breaking the Fire Triangle, the fire ceases to exist. Each detector
constantly monitors the room for signs of fire. As soon as fire is detected, an alarm is sounded,
to the personnel to evacuate the entire room. Then, the gas like, Novec, Clean Agent or Co2 is
released in the enclosed room. Thus, the oxygen in the room is rapidly reduced, to a level
where fire cannot exist.

4.1.4 Wet/Dry Riser System
Dry riser (red in color) Wet riser
This buildings have a wet riser and dry riser system. They are intended for the use of the Fire
Service to provide a readily available means of delivering considerable quantities of water for
manual or automatic fire fighting operations.
Dry riser is a vertical pipe intended to distribute water to multiple levels of a building or structure
as a component of the fire suppression systems. It do not contain water when they are not being
used, but are charged with water by fire service pumping appliances when necessary.
Wet riser is a system where the pipes are kept full of water for manual or automatic fire fighting
operations. The provision of a built-in water distribution system means that firefighters do not
need to create their own distribution system in order to fight a fire and avoids the breaching of
fire compartments by running hose lines between them.

A smoke detector is a device that senses smoke, typically as an indicator of fire. This building
security devices issue a signal to a fire alarm control panel as part of a fire alarm system, while
household smoke detectors, also known as smoke alarms, generally issue a local audible or
visual alarm from the detector itself. It located on the ceiling of the building. Smoke can be
detected either optically or by physical process (ionization), detectors may use either, or both,
methods. Sensitive alarms can be used to detect, and thus deter, smoking in areas where it is
banned.

6.0 Overview
Electricity in this world have made an impact to our daily life due to the fact that it provides us
power for mechanical ventilation and artificial lighting in the buildings. In Malaysia, there are 3
electric utility companies that provides the electricity that is demanded by the public which are
Tenaga Nasional Berhad (TNB) for peninsular Malaysia, for Sabah it is Sabah Electricity SDN.
BHD (SESB), and also Sarawak Energy (SE) for Sarawak. It all starts from a power plant that
produces high voltage current to consumer. The process is called power distribution grid,
whereby the voltage rises and drops depending on function and locations. The generated
electricity will pass through the step-up transformer to raise the voltage to HV of transmission
voltage. The purpose is to cover back the energy loss due to the resistance in the transmission
wire.
SS15 Courtyard received 11kV of electrical supply from the TNB substation. The electricity is
distributed to the High Tension Room of the building. The electricity is then stepped down by the
transformer to 415V and moved to the Low Voltage Room to supply electricity to the Riser
Room of every floor of the building.

6.1 ELECTRICAL SUPPLY ROOM
6.1.1 HIGH TENSION ROOM
The High Tension Room is at the ground floor of SS15 Courtyard. The incoming electrical power
supplied through a 11kV feeder from TNB. The underground cables of the 11kV supply is
connected to the 11kV switchgear inside the high tension room which is just next to the TNB
substation. The high tension room has switchgears which consists of switching and protection
devices such as fuses, vacuum circuit breakers, isolators, disconnect switches, overcurrent and
earth fault protection (OCEF) relays and other devices that control the flow of electricity. The
high voltage electricity at 11kV will be step down using several step-down transformers
depending on the power demand of the end user, which in this case will be the tenants and
management of this building.

with the OCEF relay in blue colour contact arms on a withdrawable trolley
A vacuum circuit breaker (VCB) is used as an ON/OFF device to control the flow of electricity.
Due to the high voltage of 11kV, the actual ON/OFF switch must be operated inside a vacuum.
In the above picture, the white coloured cylinders is the actual switches, technically named
"interruptors". The operation of the ON/OFF switch can be controlled manually (for simple
switching to ON or OFF) or automatically when abnormal situations are detected by the OCEF
protection relay. When an abnormal situation is detected by the OCEF relay, such as an
abnormally high current flow or leakage of current to earth, this protection relay will
automatically "trip" (switch OFF) the VCB to protect the end users and equipment from damage.

6.1.2 TRANSFORMER ROOM
In SS15 Courtyard, there are 2
transformer rooms. Both of it are located
at 2 different locations. The smaller
transformer is located at the Ground
Floor, whereas the bigger transformer is
located at the Basement. The step-down
transformers are placed in these rooms in
order for them to step down 11kV of
electricity that is coming from the High
Tension Room to 415V. The stepped
down current will then be transferred to
their own Main Switch Board (MSB) that
are located in the Low Voltage Room.
MS 1525:2014 7.3 Transformers
7.3.1 All supply voltage transformers in the building’s electrical system shall be selected based
on their overall efficiency according to their load profile, taking account of the capital cost and
cost of losses. Such a selection can be based on the following typical loss characteristics for the
different transformer ratings as shown in Tables 16, 17, and 18. The losses indicated in Tables
16, 17, and 18 are valid for low voltage distribution transformers and shall be applicable for
secondary windings from 400V to 433V.

The Low Tension Room is situated next to the Transformer Room. The output from the
secondary side of transformer, which is at low voltage, is connected to low tension room with
cables. The equipment in the Low Tension room has similar functions as those in the 11kV High
Tension room, but the voltage level is lower (415V), and instead of using vacuum circuit
breakers, it uses air insulated circuit breakers (ACB). In SS15 Courtyard, there are 3 Main
Switch Boards (MSB) inside the Low Tension Room that distribute electricity to the landlord,
tenants and chiller respectively. These panels are the main power switches of the entire
building.

The distribution board (DB) is also known as
panelboard or breaker panel. The main function
is to divide the electrical power feed into
subsidiary circuits while providing a protective
fuse or circuit breaker for each circuit. The
distribution board offers protection to users and
equipment from electrical shock or fire resulting
from ground fault. The electricity from the
distribution board is then further delivered to a
smaller version of MCCB, MCB and Earth
Leakage Circuit Board (ELCB).

6.1.4 RISER ROOM
Riser Room can be found at every floor of SS15 Courtyard. The Riser Room consist of
Distribution Board (DB), which is a smaller panel board that receive electricity from the Main
Switch Board (MSB) and supply electricity to every electric appliances of the particular floor that
it is situated in. Besides that, the Riser Room also consist of an Essential Distribution Board
(ESB) that receive the electricity from generator during emergency.

The Generator Set Room is located
on the 1st Floor in the building. The
generator act as a backup electrical
supply source when there is an
electrical breakdown from the TNB
station. The generator will generate
electricity either automatically or
manually within 5 seconds by using
diesel oil after it detects that there is
no electrical supply from the TNB
station. As for SS15 Courtyard, their
generator has to be switched on
manually. So when there is actually a
power failure coming from TNB
station, one of the engineers working
under the building will manually
switch it on. The generator’s power
will be pumped and supplied by the
MSB to make it run. Diesel will then
be added into the tank to run the
motor inside the generator, to help
supply emergency electricity to the building or the area affected. The electricity generated will
transfer to EMSB in the Low Voltage Room, then to the ESB in Riser Room. The generator will
generate electricity for the building until the power supply has been regained, then it will be
manually switched off until a next power failure happens. But unfortunately, the power supplied
by the generator will only be enough for the lightings which are directly connected such as the
lifts, lobby or toilets. As for the offices, electricity will not be supplied there due to the shortage of
electric supply.

Ventilation System
Flexible Bellows
When the generator is switched on and running, it will generate electricity when the motor inside
starts to run. This will cause the generator set to produce heat. Therefore, a ventilation system
is needed in the generator set room to prevent the generator from overheating. Which is why
the flexible bellows attached to the back of the generator, will act as a medium to let the hot air
out through a louvered panel in order for the heat to not be trapped.

Diesel Tank
In the picture on the left, it shows the maximum area
where we were allowed to have access to. The
purpose of a diesel tank is to store the diesel to run
the generator when it is switched on to supply
electricity to the building during power failures. This
is due to the fact that battery has much lower specific
energy than the fuel like gasoline, therefore diesel
fuel is required to work out the generator while still
using battery to operate. Even though gasolines can
only be stored for about a year, disposing it would be
difficult. When the diesel fuel passes through the
motor and allow combustion to occur, the dynamo
will generate electric field and current will be supplied to the LV room, later followed by the
distributing areas.

Carbon Dioxide Tank
The purpose of the carbon dioxide tank is when a fire breaks out in any of the rooms, a carbon
dioxide pilot will pull its trigger to conduct those tanks to work to put out the fire during
emergencies. These tanks are needed in every electrical supply room for safety purposes.

PROBLEMS
82. School of Architecture, Building and Design
Taylor’s University | Building Services II | “SS15 Courtyard, Subang Jaya”
81
Problems of Mechanical Ventilation and Air- Conditioning
Cooling Tower
Cooling tower continuously wash by condenser water, inevitably it is exposed to the risk of the
growth of algae and bacteria like Legionella. It also cause problems like corrosion and fouling
which will increase health risks.
Corrosion often associate with cooling tower as it always expose to air and water.
Fouling is the deposition of suspended material from internal sources such as by-products of
corrosion or dust around the cooling tower.
It is a serious problem as it will increase the hardness of water and water consumption.
Blockage in the water basin of cooling tower may happen, eventually lead to leakage.
All these problems reduced heat transfer efficiency and therefore reduced the efficiency of
cooling process. It will then increase the energy consumption by refrigeration chillers and
greenhouse gas emissions.
83. School of Architecture, Building and Design
Taylor’s University | Building Services II | “SS15 Courtyard, Subang Jaya”
82
Problem of Fire Protection System
Fire Door
Through our observation, we realized that most of the fire door cannot close automatically.
However, exit doors shall be close automatically when released and all devices including
magnetic door holders, shall release the doors upon the power failure or actuation of fire alarm
as stated in UBBL 1984 section 173 (2). Thus, the fire door cannot compartment the safety zone
and the fire area when fire breaks out which cannot protect the occupants in the building.
84. School of Architecture, Building and Design
Taylor’s University | Building Services II | “SS15 Courtyard, Subang Jaya”
83
Moreover, we also found that the advertisement boards are placed in front of the fire door. This
will block the occupants when they escape from the building during the fire break out due to
there have many obstruction in front of the fire door. The management of Courtyard has not
fulfilled the requirement of UBBL 1984.

RECOMMENDATIONS & SOLUTIONS ON IMPROVING AIR CONDITIONING
SYSTEM
Cooling Tower
1. Regular maintenance
First, the contaminants in the cooling tower should be removed and keeping it as clean as
possible. Fix the damages on cooling tower like leakage and broken panel. Do inspection
regularly to ensure it functions properly.
2. Continuous monitoring
Purchase equipment and software to supervise the cooling-system water. This process includes
checking the water quality and system efficiency. Warning will be given to the facility team when
there is any potential decline in water quality.
3. Systematic filtration
Side stream filtration helps to draw out trapped contaminants that may circulate in the water
before they can accumulate in the basin and reach other parts of the system. After the water is
filtered, it returns back to the chiller room or cooling tower. It can be installed at the side of the
water basin or the condenser water return pipe. It is cost effective as it only filters a portion of
the water flow, it doesn’t need to be compatible with the system’s recirculation rate. Side stream
filtration system eliminates shutdown time as it can be cleaned while the cooling systems are
running. By removing the suspended contaminants, all the problems (growth of algae and
biological bacteria, fouling and corrosion) can be solve directly or indirectly.

86
RECOMMENDATIONS & SOLUTIONS ON IMPROVING FIRE PROTECTION
SYSTEM
FIRE DOOR
After identified the problems, we suggest to apply an electronic magnetic door catch to every
single fire door. The magnetic fire door catches/holders will allow a fire door to be held open
electro-magnetically allowing a free flow of traffic. In the event of a fire (or power failure), the
magnet is released and the door closer will close the fire door securely to help limit the spread
of fire throughout a building. This type of door control is ideal for busy corridor doors as found in
the shopping mall, schools or even hospitals.
The fire door could be open but it will closed properly when emergency/fire burn out. It suit for
the needs of courtyard allowing a free flow of traffic. At the same time, it can be a very good fire
protection system by releasing the door automatically.
88. School of Architecture, Building and Design
Taylor’s University | Building Services II | “SS15 Courtyard, Subang Jaya”
87
In addition to that, for the problems of advertisements blocking the fire exit door, we can actually
instruct the mall security guards to remove it when they doing their rounds. If the same
problems happen in second time again, the mall management can catch the people by
monitoring the CCTV and give them a fine.

CONCLUSION
Through observing SS15 Courtyard, we found that the building services in this building are
being well maintained and a majority of them had meet the basic requirements and standards of
the rule according to the Uniform Building By-Law 1984 (UBBL).
Maintenance to the building is very important because it can maintain the effectiveness and
efficiency of the building systems. Services such as repairing, servicing, renovation and
replacement should be carried out frequently.
Throughout this assignment, we are able to identify, understand and explain the type of building
system such as air conditioning system, fire protection system, vertical transportation system
and electrical supply system. Besides that, we are also able to understand how the system work
and its function. Moreover, we also can differentiate and distinguish the installation of various
types of services in this building. Other than that, we are able to work in a team and learnt to
tolerate each other to complete this assignment effectively.
In a conclusion, building services play an important role in a building. It makes the building more
comfortable, functional and safe to use.
