| Regulation of Lighting in Housing Estates |
| Victoria Junior College |
| Donovan Chan Shi Jie, Zhang Chen, Li Yu Fei,
Yam Junjie, Chen Yiliang |
The aim of our project is to conserve
electrical energy consumption in Singapore, with
the focus on reducing the amount of electricity
consumed by the ceiling lights of HDB apartment
blocks island wide. We have observed that in HDB
flats, the lighting located in the stairwells
and along the corridors are being left lit throughout
the night. This consumes large amounts of energy,
which in turn requires more fossil fuels to undergo
complete combustion industrially. We have also
identified this as a main concern for the high
levels of energy consumption in Singapore. Therefore,
we have thought up a system which not only reduces
the amount of energy being used, and it also does
not compromise on the residents’ safety
and convenience. We then decided to use motion
sensors that are strategically placed in common
areas (e.g. corridors) to only light up that level’s
lightings only when there is activity within that
vicinity while at the the other floors; the lights
are not in function. We have also calculated that
by implementing this system in HDB blocks, we
would conserve a lot of energy in the long run
and hence this system is also economically viable
for Singapore. Our system works on the basis of
the use of ultrasonic sensors to control lighting
within a HDB block. Its primary aim is to conserve
electricity and in the process, save money. Conventionally,
HDB corridor lights will always be switched on
from 6.45pm till the next morning at roughly around
7.00am. In this case, energy is wasted as even
though there is no use for such lighting, it is
being switched on throughout the night. In our
system, instead of the usual switching on of lights
at the corridors from 6.45pm till the next morning,
the corridor lighting would always be switched
off. By using sensors to sense the presence of
activity within the range of the sensors, the
lighting for that particular corridor would be
switched on. This would then allow the HDB block
to save money and still not compromise on the
resident’s inconvenience tobe ‘walking
in the dark’.

Water nowadays is becoming lesser
and more precious as people use a large amount
of water in our daily life. Water is also used
in many activities such as in car wash, laundry,
food industry, manufacturing and more. We have
an innovation of saving water rather than wasting
water. Our design can make a difference so that
relatively “clean” waste water can
be recycled for other uses. In future, this design
can help to reduce high water bills, keep the
environment clean and reduce misunderstanding
between countries where we are dependent upon
to supply water. Water is our future. We need
to save as much as we can so as to conserve the
little resource that we have. The benefits of
using this water management system is to reduce
the amount of water used in a household as the
system will separate very dirty used water from
relatively clean water, the little saving of this
precious water can be put to other use as in the
watering the plants, washing cars and other uses.
It will help to reduce the water bill of a household.

Public garbage bins can be dirty
and produce an unpleasant smell, especially when
they have not been emptied for several days and
there are perishables, such as food waste in them.
Liquid waste that is thrown into the bins, such
as unfinished drink cartons and unwanted raw food,
can also produce leachate within the bin and stain
the bottom of bins especially when they have dried
up. In addition, garbage bins can post hygiene
and health problem when flies, rats, maggots,
stray cats and other pests are attracted to them.
In fact, this is an environmental problem that
still persisted in various neighbourhoods and
areas. This project aims to improve on the current
structure of garbage bins so that waste disposal
is more hygienic and environmentally friendly.
The proposed bin will reduce the smell produced
using a lining of chemical substances and layers
of recyclable materials at the bottom of the bin
will also separate liquid from solid waste when
plastic bags tear due to the heavy weight of fluids.
These layers are disposable and can be recycled.

| Energy Reducer |
| ITE College West (Dover Campus) |
| Xu Li Li, Najima Bte Raheem |
Our idea is to design and
develop a low cost motorised mechanism
for the mounting of solar panel so that
it can track the sun as it moves. Eventually,
the panel would achieve maximum solar
energy conversion throughout the day,
hence to achieve the objective of reduction
other energy used. Our objectives are
to provide a low cost power source to
campers, hence reduce energy usage from
other sources, to design a simple tracking
mechanism and easy to set up, machine
is intelligent and able to do auto tracking
and resetting and can be adapted for permanent
installation. We have developed a simple
a single axis mechanism to track the sun.
At the same time, in order to reduce initial
cost of set up, we designed a simple sun
tracking sensor. To instill intelligence
into the machine, a micro-controller will
be programmed to provide continuous tracking
of sun movement and reset the panel back
to the East in the night. Sensors together
with micro-controller will provide light
sensing and movement of photo voltaic
panel. Based on the principles that light
travels in straight line, the micro-controller
will continuously orientate the panel
towards the strongest sun light direction.

Our proposed plan is to
study and identify the wastage of energy
and resources in the common household.
Thereafter, we plan to solve these problems
by designing an “EcoFlat”.
Preliminary ideas include the adoption
of innovative features such as utilising
polarised windows to block out the heat.
In this way, the EcoFlat will be environmentally
friendly in all aspects, conserving the
environment in multiple ways. Other physical
factors are also considered, such as windows
built facing the North and South to avoid
direct sunlight. The EcoFlats, if adapted
by the HDB, could prove vital for a sustainable
future. This unique design for future
HDB housing projects would allow an all-rounded
environmental conservation effort through
innovating features and specifications
in their architecture.

In water scarce Singapore,
conservation of water is very important
and awareness is the first step in water
conservation. A breakdown of indoor water
use shows that 50% of water is used for
toilet flushing and laundry. With this
study results in mind the team decided
to do a project to “Re-use water
from washing machine discharge for toilet
flushing and recycle to washing machine
for first round washing.” The project
is estimated to cost $4,000 to develop.
It includes both the necessary hardware
and developmental software costs. This
project, if implemented, will go a long
way in helping every Singaporean to save
the country’s treasured water. Water
is essential to our health and the health
of our economy. The team believed that
their innovative “Recycle Water
Project” will be the pioneer system
that can effectively save water for the
nation and save money for every household
that implement this system. The prospect
of commercialisation is excellent.

This is a revolutionary
idea – beyond its active action
of floating litter collection on water
surface, it serve as a dynamic icon to
promote and develop a culture of active
caring for our environment – remove
littering & “make it a better
place”. Captain Green was a character
in National Education Program to promote
care for our environment in a fun way
since 2000. It went online with poems
and songs. It went further with a “Captain
Green Column” and “Chat Forum”
on ENV’s website for students and
the public to share their ideas, contributes
suggestions, poems and songs on the environment,
as well as involved Fellow Singaporeans
in discussions on environment issues.
Here, we take a big step – makes
Captain Green comes alive as an intelligence
Robot – Captain Green-Bot. This
can be a national scale project –
with a few teams of Captain Green-Bot
(solar powered mobile robot with GPS guidance
and remove vision) at a few reservoirs.
Beyond its basic function of litter collection
on water surface, it promotes and develops
the culture of Green environment. It will
attract and make friend with people around,
educate and encourage people (through
SMS conversation) to follow its example
of “make is a better place”.
Hence, it develops a long-term “Total
Solution” – to improve and
clean our environment for both land and
water surface. This project also opens
up the endless possibility of applications
and support Singapore Green Plan 2012.
More fun can be added with animation and
web pages with life video on life of Captain
Green-Bots and even the video viewed from
the Captain Green-Bots. Further extension
may be addedd with underwater sensor for
object or even human body searching.

Most of Singaporeans enjoy
showering and spent long hours in it.
Not only that, many like to have hot showers
despite the hot weather, thus leading
to the rise of their utility bills. This
“2-in-1” monitoring device
provides real time monitoring on the water
consumption as well as the energy consumption
at home. This device will measure the
amount of water and energy consumption
simultaneously and converts it into cost
of usage respectively. The display panel
will display the cost of water usage &
energy usage according to the flow rate
& energy transfer rate. The display
is on per usage, it means it will auto
reset after certain time delay. This will
keep track of individual user’s
usage each time they take shower. It also
displays accumulative cost on daily and
weekly basis. Most importantly, this device
provides an alarm feature when consumers
had exceeded certain amount of water or
energy usage. These information empowers
consumers to make education decision on
energy conservation. It also helps to
develop a culture of conservation.

The objective of the project
is to have two forms of water supply into
the WC storage tank of a standard sanitary
toilet system. This idea came about when
we discuss on the drainage of waste water
of cloth washing from a washing machine
pumped out into the drainage. Out of the
discussion, some felt that the waste water
can be reused again e.g. it can be kept
in a container to wash corridor floors,
school shoes, toilet floors and even toilet
sanitary. Why not we target on toilet
sanitary? This is where we can actually
save water from using the dual water system.
The project requires two tanks, sanitary
storage and a reservoir. The reservoir
tank stores the waste water whenever the
washing machine discharges water for a
complete washing process. Any overflow
of the reservoir tank will be managed
by a vent; therefore the reservoir size
depends on the capacity. For a standard
WC storage tank, there should be a floater
tap switch to control the flow of water
supply from the Public Utilities Board
(PUB) and a WC flushing system. So the
flushing of the sanitary depends solely
on using the water from PUB.

Waste acetic acid (CH3COOH)
produced during our practical training
is usually contaminated with other by-products,
and is sent for disposal. The project
is to produce carbon dioxide gas from
this waste stream by applying acid carbonate
chemistry and chemical processing principles
using a modified pilot process rig. The
gas is then recovered and stored for training
use. The process also converts the acidic
waste to a more environmental-friendly
form that is suitable for environmental
studies. Students from our institute have
the opportunities to use the carbon dioxide
gas and treated process liquid that are
generated for their course training. Our
project explores the possibility of reprocessing
and recycling waste meant for disposal
by generating useful products that meet
training needs. This will improve the
waste management system of the institute,
provide an additional source of training
materials that benefits students’
learning and reduce training cost in the
long term.

| Auto water saver |
| ITE College West (Dover Campus) |
| Alina Wu Yuanxin, Li Pei En |
Many a times, whenever
we want to fill up say a pail of water,
we would tend to wait for it. Thus, as
a result, if we are the impatient type,
we would tend to multi-task with other
things, which if not manage properly,
would lead to the precious water being
overflow. Thus, the project looks into
auto-monitoring the water’s level
which when an appropriate level is reached,
it would auto turn off the tap, thus,
saving the water from being overflow.
The Auto Water Saver is an integrated
controller system that combines logic
controller and mechanism technology into
a intelligence system consisting of the
sense module and the Mechanism module.
The Auto Water Saver offers solution auto
monitoring the level and thus activating
the stepper motor to turn off the tap,
which in turn saving precious water from
being overflown.
