Air conditioning and Mechanical Ventilation

Introduction

It uses the centralized system for almost all of

spaces in the Point 92 building.

The air-conditioning systems help to keep the

office cool and comfortable for a moreconducive working environment.

System

Centralized system that require a chiller plant

room, AHU (Air Handling Unit) room and also a

cooling tower. Components such as ducting,

fan-coil unit and diffuser can also be found in

this office building.

Water, Sanitary and Plumbing Systems

Introduction

This office building tries to save as much

when it comes to water, sanitary and

plumbing systems.

System

The domestic water is pumped by the

filtration room from the suction tank to

the water tank which is located on the

rooftop. For the toilet, it uses waterless

urinals which applies the liquid barrier

systems. It is an oil-based sealant that

floats on top of the urine to prevent

odours. The taps are one of the water

efficient fittings which use as little as 2

litres pe.r minute.

Other than that, Point 92 building uses

the Water Condensate Recovery using a

mechanical pump. For this, a standby

pump, a duty pump and a jockey pump is

used. A plumbing is provided at one

corner of each office for pantry use.

Electrical and Telecommunication Systems

Introduction

It uses the conventional method of supplying electric by the

Substation to the distribution boards on every floor by an

electrical riser. The TNB substation uses dual feed system

that applies GBI requirement. So, the generator is notcommonly used in this building according to the technician.

For the offices, junction boxes are provided on the floor for

electrical and telecommunication purposes. Underfloor

trunking is applied in this building.

System

To control and manage every system around the building, a

Building Automation System using the computer is set up in

the control room.

Fire Fighting Systems

Introduction & System

Active fire fighting systems are widely used in this office

building, most of the door are 2 hour fire rated door.

Sprinkler pump room is located at the basement. A flow

switch is used in order to control the sprinkler valve frombreaking. An ABC dry powder is located in each wing of

every office. There is a blower in the staircase to avoid the

fire from blocking peoples way during emergency exit.

Introduction

The Point 92 building uses rainwater harvesting system by collecting water from the roof top surface that flown to the drain, down to

rainwater down pipes, which filtered by debris trap.

System

By utilizing this system, the rainwater act as independent water supply for the building that give the benefits on lowering environmental

impacts and reducing the cost of water bills.

ANALYSISComparison of using green design rather thanconventional methodRainwater harvesting system

Rainwater are one of the resources that is commonlyneglected and not being harvested even though it isabundant. Rainwater from the roof surface is channeledout directly to the drain without using it back causingoverflown drainage that leads to flash flood.By using rainwater harvesting system, water collectedand being stored can be used for irrigation, flushing toilet,and clean water if it is fil tered and treated properly. Costreduction of water bills and sustainability is achieved byusing green design rather than conventional method.Waste reduction and recyclingWaste from unwanted material are the major cause ofpollution, by recycling back the unwanted material andwaste reduction, can be beneficial to the environment.Cutting the paper usage by replacing printed data toelectronic data is one of the effort of green solution ratherthan conventional way.

VegetationTo corporate with green design, planting lush vegetation isa must, most of the conventional building cut off the greenarea that causes hotspot, deforestation that lead tolandslides and unpleasant views. Greenery helps tofiltering the air, provides shade, evoke calmingatmosphere and doing justice to nature.Looking up green design rather conventional methodopens up possibility to using nature in a right way as acatalyst for economic purpose.

ANALYSISComparison of using green design rather thanconventional method

Building Energy System

The electrical power supply uses a dual feed supply. It isbetter than the conventional method of only providing onebecause if anything happens, theres a back up power for

this office building. However, the generator set provided israrely being use due to the dual feed supply of electricalpower. In my opinion, it is a waste of space and money toput it the generator set when theres already a TNBsubstation that has dual feed supply following therequirement of GBI index.

The sanitary fittings are very efficient as it save long termcost although it is quite high in terms of capital cost.These systems should be applied in new buildings in orderto save the long term cost and most importantly theenvironment.

Window and Glazing System

The window and glazing system is better thanconventional as it traps in hot air and keep the air indoorquality at good stake. This should be applied in theconstruction of windows to achieve human comfort level.Other than that, this office building only allows the user toput in blinds instead of curtains to make sure that thelarge amount of natural lighting being used to light up theoffice rather than using artificial lighting that would boostelectric bills.

CONCLUSION

As a conclusion, we can conclude that the building arewell equipped with green system and all of them are ingood care. The building energy systems are all in good

hand by the engineers, technician and such.

The green area provided are enough to make it as a

better working environment for workers in the officebuilding. It also functions as a filter for heat.

In a nutshell, we can conclude that from what we havelearned and observed, we should apply these green designinto our project for a better building quali ty for people to

enjoy. We hope that these knowledge will give us anadvantage in the real practice later.
