What is Building service?

One of a crucial role in a building Building service is responsible for the design of :

Installation Operation Monitoring of the mechanical, electrical and public health

systems Safety, Comfortable Environmentally Friendly Operation

Influence the architecture of a building Play a significant role on the sustainability and

energy demand of a building

Page 3: Building Services II

The Summit, Subang USJ

The Summit located at Subang Jaya, USJ Purpose of choosing The Summit as our case

study: Locate all services within the building Services in the building quite old Low maintenance The Summit used to be popular

place for youngster & families Less and less popular due to

the poor management of the building

Page 4: Building Services II

Why is building services so important?

Building services is ‘what makes a building alive’Makes the building safe and aliveWithout building services, we won’t have lighting,

heat, escalator, lift, acoustics, plumbing, power supply, the security and safety system in a building

Without all this it will only be a cold, dark and uninhabitable building

Page 5: Building Services II

First impression of The Summit!

Safety system are spoiled and poorly maintained Examples are the emergency phone and the fire

escape door which is allocated near the stairsThe environment in the building is dark and creepyThe population is lesser compared to other

shopping complex

Page 6: Building Services II

How can The Summit attract more shoppers?

Improve the lighting to be more brighterAdd more interior decoration around to make the

building look more livelyKeep the services updated by maintaining it

regularly

Page 7: Building Services II

Natural vs. Mechanical

During our visit to The Summit, we found out that both natural and mechanical systems of ventilation are implemented

In the washrooms, there are 3 openings of windows to provide ventilation. There is also a fan blower inside, which is of the mechanical system.

Page 8: Building Services II

Split Units

Air doors are installed at every automatic sliding door at The Summit To prevent loss of cool air To prevent hot air from coming in

Condensers are normally located around the basement level or the rooftop.

Page 9: Building Services II

Centralized System

In the main area or lobby of the building, centralized system and air-conditioning is installed.

With this system, fresh or cold air is transfer through ducting to various part of the building.

Page 10: Building Services II

Water Chiller System

The cooling tower is located at the top of the building, along with other services, for examples; piping, split units & electrical distributor

Page 11: Building Services II

Diffusers

Diffusers are where the air comes out and is discharged into the rooms.

In The Summit, 3 types of diffusers: Linear Diffuser

It is used in open plan rooms and it will hardly interfere with the pattern of the ceiling.

Its direction of air discharge can bechanged to suit the room conditions.

It is suitable with high air velocity and it has high induction slot can have rapid decay of air velocity and temperature.

Page 12: Building Services II

Diffusers

Cone Diffuser Its shape can sometimes be square to match pattern of

the ceiling and its inner cone can be lowered or raised to result in different flow pattern.

Page 13: Building Services II

Diffusers

Side Wall Inlet Diffuser It is used when there is no false ceiling. For every inlet

there will be a grill. The air discharge can be controlled by sets of louvers in

vertical or horizontal plane. The flow pattern can be varied according to room size, velocity and aspect ratio.

Fire Protection

• Active fire protection • Method requires mechanical, electric or electronic

activation• Manual or automatic fire protection system• Eg. fire alarms, detectors, wet and dry risers, hose reels,

carbon dioxide fixed installation• Passive fire protection• An integral component of the structural fire protection and

fire safety in a building.• Contain fires or preventing the fire from spreading• Eg. fire-resistant walls, floors, and doors, etc.

Page 15: Building Services II

Active Fire Protection

Fire ExtinguisherIntended for initial outbreak of fireFour different types of fire extinguishers

Page 16: Building Services II

Active Fire Protection

Hose ReelIntended for occupant to use during early stage of

fireLocated at every escape routes19mm diameter25m in length

Page 17: Building Services II

Active Fire Protection

SprinklerDetect, control, extinguish fireWarn the occupants of the occurrence of fireEquipped with control valve to deliver the pressure

of the sprinkler water

Page 18: Building Services II

Automatic fire alarm system Manual fire alarm system

Automatically initiates and activates the alarm when it detects fire

Eg. fire detection system

Provides an alarm to be activated only when it is switch on by someone

Eg. Manual call point

Active Fire Protection

Page 19: Building Services II

Passive Fire Protection

Fire-resistant doorMainly for fire escape doorsShould not be obstructed by any objects

Page 20: Building Services II

Staircase Fireman Lift

Staircase were properly designed

The dimension of the threads and risers were constructed consistently

No winders built Length of the landing is not

less than the width

The fireman lift is indicated

Passive Fire Protection

Page 21: Building Services II

Problems The fire extinguishers were

not send for maintenance Maintenance has to be

done to ensure that the extinguisher is still functional

That the manual fire alarm is ‘not in use’.

Page 22: Building Services II

Problems

The fire doors are not in good conditionFor example, the quality is degraded, the doorknob

is missing, and the doors should always be closed and should not be obstructed by any object.

Page 23: Building Services II

Problems

Their voice communication systems are not in suitable conditions and not maintenance were carried out.

Page 24: Building Services II

Vertical Transportation Systems

Population of The Summit around 5000+- Area of The Summit

1.2 million square feet; it is a commercial building consists of 9 floors including basements

Only one bus stop in front of The SummitThe Summit poor in position of building in

relation to public transport services, which means it has low passenger peaks during arrival hours.

Page 25: Building Services II

Lift

The Summit used hydrauliclifts

Total numbers of 5 passengerand 6 fire’s man lifts on every floor

Page 26: Building Services II

Lift Car

• Capacity of the lift car is 20 passengers

• Lift entrances about 1160mm wide with 2 pieces of doors

• 50 seconds for door closing time with 1160mm width doors

• Passenger transfer time at 50 seconds in and out

Page 27: Building Services II

Problems of the Lift

• 5 passenger and 6 fire’s man liftson every floor, but only one passenger lift is working

• The Summit used hydraulic lifts, andit supposed to be low vibration and noise, but it causes a lot of vibration and noise during the ride

• Less Maintenance

Page 28: Building Services II

Escalator

• Two types of escalator:• One way traffic of single bank

with interrupted traffic in one direction on every floor

Page 29: Building Services II

Escalator

Two-way traffic parallel located in the cinema

Page 30: Building Services II

Electricity Supply Systems

The main switch boards are located around the building examples are at the rooftop, at the ground floor and the basement parking

The pictures above show the different location of the main switch board

Page 31: Building Services II

Electricity Supply Systems

Function of the main switch board: act as an assembly of switches and circuit protection

devices from which power is distributed It is totally enclosed,

sheet steel fabricated Distributes large incoming supply

into smaller, easily controlled parcel

Page 32: Building Services II

Recommendation for Fire Protections

The Summit Recommendation• Nearest fire hydrant is 51 meter

away.• A good one should be 6 meter

away.• Not more than 30 m away from

the building.

• 19mm diameter hose reel. • 25mm diameter hose reel.

Page 33: Building Services II

Recommendation for Fire Protections

• Hose reel length is 25 meter. • A good one should be 30 meter length.

• Smoke detector system.• The number of detectors should

not be less than 1 in 100m².

• Heat detector system.• The number of detectors fitted

should not be less than 1 in 50m²

Page 34: Building Services II

Recommendation for Vertical Transportation

The Summit Recommendation

Hydraulic Lift Electric Lift

• Speed is slower. • Speed is faster.

• The pump works against gravity to push the car and its contents upwards.

• Movement is depending on the electrical power.

• Energy used to lift the elevator does not get recovered on the trip going down, it is completely lost.

• Do not use as much energy due to the counterweight.
