Fire Protection SystemActive method

Passive method


5/38

Active method Fire extinguisher-Fire extinguisher is an equipment that helps to put out fire. There aremany different types of fire extinguishers such as water, foam, dry powder

and carbon dioxide.

7/38

Active Method Sprinkler system

-It is designed to detect, control, extinguish a fire and warnthe occupants of the occurrence of fire.

Sprinkler system


8/38

Passive method Fire door-Fire door is a door with a fire resistance to reduce the spread of fire orsmoke between compartments

Single leaf fire escape door Double leaf fire escape door


9/38

Passive Method Fire escape plan

-Fire escape plan is one of the methods to guide the

occupants to evacuate to a safer place


10/38

Passive Method Staircase pressurization

-It is used to keep protected escape routes of a building clearof smoke by introducing sufficient fresh air

Water ChillerSystem

Diffusers


12/38

Centralized System In a centralized air conditioning system, few major

components are involved in order for the system towork as it was required to work. These componentsinclude the cooling tower, the Air handling unit andthe water chiller, diffusers etc.


13/38

Diffusers Multi-directional diffuser-Ensure the air distribution is effective

-The blades are individually adjustable

Linear diffuser-High induction slot

-Directions of air discharge can be adapted to room conditions

Cone diffuser-Inner cone can be raised or lowered

-Sometimes square to match ceiling panel


14/38

Water Chiller SystemWater chiller is a refrigeration machine which

produces chilled water ( Approx 7 Degree C ~ 12Degree C).The primary function of a chiller is to lowerthe temperature of water to such value such that it can

be used for producing cooling effect


15/38

Vertical transportation systemEscalator Elevator


16/38

Escalator Parallel (Two way traffic)-Parallel escalator moves people in two opposite directions

which are arranged side by side to each other. Parallel

arrangement is used to prevent heavy traffic flow Criss cross (Two way traffic)Criss cross escalator moves people in opposite directions ina criss cross pattern. Criss cross arrangement allows thecustomers to travel to upper floor with the least amount oftime required without any waiting time


17/38

Elevator Hydraulic elevator-Hydraulic Elevator uses the principles of hydraulics to pressurize anabove ground or in-ground piston to raise and lower the car

Electric elevator-It generally powered by electric motors that either drive traction cables orcounterweight systems like a hoist, or pump hydraulic fluid to raise a

cylindrical piston like a jack

Low Voltage Room Main Switchboard

Generator Set

4) Electrical Panel Room


20/38

TNB Room

3 feeders

25 VCB

Installed in high voltage room

VCB is used to prevent fire outbreak

over flow of electric


21/38

Transformer Room 17 transformers

Located in transformer room

5 transformers is for the HVAC system HVAC system 11kV to 3.3kV

Remaining transformers is for normal use

Step-down for normal use from 11kV to 415V


22/38

Low Voltage Room

Main switch board to the miniature circuit breaker,then to distribution board through the bus bar, andto the load.

Located at low voltage room with the gen-sets Three main switch board, consists of 2 feeder pillar,

one duty and one standby and bar couple Bar couple is to transfer the electric from one feeder

to another

Miniature circuit breaker, protectthe electric circuit from damagecause by overload or shortcircuit automatically.


23/38

Gen-set 3 gen-sets in the building

Located in low voltage room

2 gen-sets are 100kVA and 1 is 1250kVA


24/38

Electric Panel Room Consists of distribution panel, miniature circuit breaker

(MCCB), and busbar Busbar transfers electric supply from the main switch

board to loads in each floor of the building. Distribution panel distributes electric supply from the bus

bar to the shops in the building

Problems and solutions


26/38


27/38

Problems of existing Air-

conditioning system Passive Design:

E) Shading


28/38

Solutions of existing Air-

conditioning systemActive Design:

A) Weak mechanical air distribution equipment

Solution: Multi-direction diffuser must be installedinstead of linear diffuser to avoid weak airconditioning


29/38


conditioning system B) Heat energy loss and C) Head Loss

Solutions to B) and C)

1) Seal all the leakage2) Use insulated ducting


30/38


conditioning system D) Bad indoor air quality near to vehicle entrance

Solution:

Air curtain should be installed at vehicleentrance in Subang Parade. An air curtain

is a continuous broad stream of air

circulated across a doorway of a conditioned

space. It reduces penetration of insects and

unconditioned air into a conditioned space

by forcing an air stream over the entire

entrance.


31/38


conditioning system E) Shading

Solutions: Growing big trees around exterior of Subang Parade

is considered as one of the best method of shading.

Although there are some small plants at the exterior

of Subang Parade but the small plants cannot help

much on reducing the surrounding heat. Big trees

can reduce air temperature by blocking sunlight.

Further cooling occurs when water evaporates

from the leaf surface. The process of conversion

of water to air removes heat energy from the air.


32/38

Problems of existing vertical

transportation system Hydraulic Elevator: 1) undesirable positions of elevators

2) insignificant capacity of the elevator (max 20)

3) time taken for the door to close is too long 4)slow speed of the elevator

5) no handrail in the elevator ( for aged person)

Problems of existing vertical

transportation system2) Criss cross two ways traffic escalator

The second type is crisscross two way traffic escalator.

This type of arrangement moves people in opposite directions in a

crisscross pattern. Some crisscross escalator is separated. The problem is that if the next escalator is not in sight, the passenger

will be confused where to take the next escalator and may be annoyedby that.

If there are passengers who need to travel up to many floors and do not

have access to it, it will be inconvenience for them. The other problem for it will be that the passengers will just move up

and down between floors too easily and therefore they will miss theshops on the floors and this will affects the shop sales.


36/38

Solutions of existing vertical

transportation system 1) Parallel escalators

In conclusion, we suggest applying the crisscross two ways traffic arrangementsinstead of using double, parallel two ways traffic arrangements.

Users don't have to waste their time and energy to walk past the stores simply

just to visit another floor. Moreover, this could diminish the crowded users during the peak hours.

Pursued by one way traffic, staircases brings inconveniences to particular users.

Thus the designers must take into account that the activities of the elderlywithin the mall by proper escalator arrangements.

The arrangements of crisscross two ways traffic is that the best proposal to havein the mall, however if it has inefficient space than double two ways traffic canbe the choice to possess it.


37/38

Solutions of existing vertical

transportation system 2) Crisscross escalator

The solution for this crisscross escalator is that, we suggest usingcrisscross escalator that is connected together rather than separatedones to prevent confusion from the customers.

Other than that, we can put most of the unpopular shops around theescalator so that more people will saw it to improve the sales.

The other solution for it is that build more elevators instead of this tomove people up and down faster to prevent the passengers get bored

when moving up the escalator
