heat from the chilled water.

9. AHU Room
Circulates the air
Distributes the conditioned air

10. Diffuser

11. Supply Diffuser used to discharge chilled air.
Return air diffusers are used to return warmer
air back to the AHU room.
Diffuser

12. Supply Diffuser

13. cool the space of the escalators for the user’s
comfort
Cone Diffuser
it discharges chilled air in 4 directions
spreading the air around the space efficiently.
4-Way Diffuser

14. ELECTRICAL
SUPPLY SYSTEM2

15. Electrical Supply System
Power travels from power plant through
distribution grid (Transformer, Sub station)
Electric power convert to the right amount
and supply to the building accordingly.

16. Main Switchboard Room
Place to stored switches
and circuit-protection
devices where electricity
supply is distributed

17. Meter Room
Consist electricity meters
measures the amount of
electric energy consumed

18. Distribution Panels
Switches and circuit protection
devices that serve final distribution
point

19. Electrical Conduit Tee
Conduit prevents the cable
from physical damage and
offers insulation to heat.

20. FIRE PROTECTION
SYSTEM3

21. What is fire protection system?
It is a system that prevent fires from becoming
destructive, reduce the impact of uncontrolled fire and
saves lives and property.
Consists of components that reduce or extinguish fire.
Classified into two components:
a) Active method
b) Passive method

22. Fire Protection System
1) Active method
Requires mechanical, electric or electronic system.
Basically activated manually or electronically.
e.g: Hose reels, fire extinguishers, fire sprinkler, fire alarm, etc.
2) Passive method
An integral component of a building.
Is built into a building to slow down or prevent spread of fire.
e.g: Fire resistant walls, cable coating, fire resistant doors, etc.

23. Active fire protection
Fire Extinguisher
Intended for initial outbreak of
fire.
To immediately stop the fire on
the spot.
Classified into four different
categories.

24. Active fire protection
Hose reel
Used for early stages of a fire.
Located at every escape route.
Size of the hose reel should be
19mm and 25m in length.

25. Active fire protection
Sprinkler system or Fire sprinkler
 Detect the presence of fire and
extinguishes them.
 When activated, it acts as a warning
for occupants during outbreak of fire.
 The head discharges water when a
certain predetermined temperature
has exceeded.

26. Active fire protection
Automatic fire alarm system
Automatically activated when a fire is
detected.
e.g: Smoke detectors, heat detectors
Manual fire alarm system
Provides an alarm that can only be
activated when the button is pressed
manually.
e.g: Manual call point.

27. Passive protection system
Fire resistant doors
 Mainly implemented for fire
escape doors.
 To separate off the fire
escape routes from fire
spreads.
 Cannot be obstructed by any
objects.
 Must be closed at all times.

28. Passive protection system
Staircase
To provide an escape route for
occupants during a fire.
Walls and floors are designed to
prevent immediate spread of fire.
Should be well lit.
Dimension of each riser and thread
should be constructed consistently.

29. Passive protection system
Fireman lift
It is indicated as such at the top of
the lift in a red sign.
Accessed by fire fighters to get to a
certain floor level to extinguish fire
or rescue people who are trapped.

30. Problems
Fire extinguishers
They have not been sent out for
maintenance for a long time.
Maintenance needs to be carried
out to ensure that fire
extinguishers still function
properly.
There were insufficient fire
extinguishers placed.

31. Problems
Manual Fire Alarm
The glass for it has
been replaced with a
piece of paper.
Not in use.

32. Problems
Fire doors
Well maintained but can only be
access from the inside, not the
outside.
It is always left open because it
cannot be opened once shut.

33. Problems
Voice
communication systems
The lock is broken.
Can be accessed by
anyone if found.
Only used for
emergencies.

34. VERTICAL
TRANSPORTATION4

35. Elevator
Electrical lift
15/21 people ( 1150/1600 kg )
Average 2.5 m/s
Have Machine Room

36. Things to take note of...
Mechanical Door Bumpers
a sensor that prevents the doors closes
when a person or an object blocks the
doorway.
common in older elevators and
specifically installed in Asia.
most companies have stop using these
as its occasionally malfunction and do not
retract when a passenger bumps or hits
them.

37. Escalator
One way traffic w/ interruption
Connected to underground floor
Cover east and west side
Two way traffic parallel
Cover the back/middle side

38. Things to take note of...
Travolator
a slow moving conveyor mechanism that
transports people across a horizontal or
inclined plane over a short to medium
distance.
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.

39. Recommended Type of
Systems

40. Mechanical and Air- Conditioning
System1

41. a) AHU Room has to be locked
AHU provides clean and fresh air to customers.
Suspicious act can bring toxic gas to customers.
May even having suffocation from air.
b) Cleaning and tidying the room
Looks dusty and messy when having quick look.
Materials scattered everywhere.
Air flowing from diffusers may be dirty since having dusty room.
c) Fix the outdoor kitchen exhaust vent
Being dent badly and not attached to the wall.
Birds can be seen around the building.
They may live inside the duct and create hazardous issue to people inside
the building.
