Nowadays, energy saving and emission reduction are the development trends
common to all sectors. As cradles of future leaders, a few schools have adopted
the energy saving measures and equipment according to the CLP
GREENPLUS Programme's recommendations.
This not only enhanced the energy efficiency, but also set a role model for
their students. They can then understand better the rationale and importance of
energy saving and emission reduction, and learn to 'put things to right
Energy costs often form a considerable part of the operating cost of
educational institutions. Breakthroughs are, nonetheless, possible. In fact, a
good number of institutions in Hong Kong have started to implement energy saving
and emission reduction measures. Through the participation in the CLP
GREENPLUS Programme, they are working towards the creation of
sustainable environments for the benefits of both the school community and the
Munsang College, the first school to install the GREENPLUS
Console, started to monitor the electricity usage of Form 3 classes last
September. With CLP's support and the teachers' encouragement, the electricity
usage of Form 3 classes decreased sharply by 50% within a short period of time,
which proves that the system has been a boost for the students' energy-saving
"Our school does not mean to promote energy saving and emission reduction to
cut down on electricity bills. The reason for doing that is to build up our
students' awareness and to motivate them to practise environmental protection in
a daily manner starting from their campus life." Ms. Kuby Chan, the Principal of
Munsang College, admitted that it is inevitable for the education sector to put
in a considerable amount of resources to implement energy savings. Anyhow, she
stressed that it is a matter of 'doing as much as one can', and that the goal of
motivating the students to make good use of energy is actually achievable with
The solar panels and wind turbines on the roof of the school building
generate electricity for the lighting system while providing statistical data
for student learning.
Besides the energy usage monitoring system, Munsang College also installed
solar panels and wind power generators that supply electricity for part of the
school's lighting system. Moreover, three greenhouses constructed mainly with
materials from recycled plastic bottles were erected on the playground. Mr. Chan
Wai On, Centre Coordinator of the school's Centre for the Advancement of
Renewable Energy, pointed out that such facilities help reduce carbon emission
and serve as teaching resources for school activities and inter-class
competitions related to environmental protection. The school is planning to
implement the energy usage monitoring scheme in other forms as well.
Located at City One Shatin, Baptist Lui Ming Choi Primary School set up a '
Renewable Energy Station' in 2009. The installation of solar panels and bicycle
generators generate electricity for the school's ecological park. Ms. Linly
Wong, the Headmistress, said that the station enhances students' knowledge in
renewable energy and environmental conservation, which in turn motivates them to
develop the habit of saving energy.
To encourage students to put energy saving and emission reduction into
practice, the school received an on-campus energy audit and gradually phased out
conventional appliances with CLP's support. T5 energy-efficient fluorescent
tubes have been adopted, and the GREENPLUS Console (a campus energy
usage monitoring system) was installed to record the school's electricity usage
and carbon emission.
"The system was first put into trial run in Primary 4, 5, and 6 classes.
Electricity usage of each class is displayed on the screen in the school
playground. Teachers and students can freely access the statistics, as well as
energy saving tips and other relevant information on environmental protection in
one go." Wong said. As the system captures statistical data on the classes'
electricity usage in various time cycles, Wong believed that it helps teachers
and students alike to manage their electricity usage, which in turn motivates
them to find out innovative ways to enhance energy efficiency through
"We hope that students can make energy saving as part of their
daily life with the help of the system, so that the energy costs can be reduced
to free up resources for the facilitation of programmes beneficial to student
Some people may think energy saving is all about reducing energy use.
According to Lam Kin Lai, HKUST's Associate Director of Facilities Management,
energy saving actually refers to 'putting energy to right use'. Therefore, the
university has been taking comments of faculty members and students to create an
eco-friendly and comfortable campus environment with the adoption of
energy-efficient equipment and technology, including solar-powered lighting
"Let's take the example of student hostels. We have switched to electric
water heaters in recent years for its numerous advantages, including energy
efficiency, safety and convenience," Lam said. Lam added that replacing the
conventional appliances with energy-efficient ones not only reduces energy costs
but also improves energy efficiency, which in a way creates a low carbon
lifestyle for all teachers and students in the university. With the support of
CLP, a heat pump system has been installed in the university library which
stabilises the room temperature and humidity.
The replacement benefited the university in two encouraging ways. The number
of books affected by mould decreased from several hundred to only less than a
hundred per year. Also, the university has been able to save HKD 1,000,000 a
year on energy costs. Lam said the university has been replacing the lighting
systems on campus and installing motion sensors or dimmers to further improve
Located in Tuen Mun, Yan Oi Tong Tin Ka Ping Secondary School is an
award-winning school which sees environmental education an important aspect for
student development. The school has set up a 2,000 sq.m. eco-garden, named as
the Science and Ecological Learning Centre, for its students to experience
organic farming and recycling fun.
The school’s motto is to help others, the eco-garden is committed to helping
underprivileged in the community by providing them with healthy organic produce.
It targets to serve a community of over 25,000 people in Tuen Mun in two years
through organic farming.
To support the development of this successful and meaningful educational
project, CLP and the school have jointly launched the Green School Program to
assist the eco-garden in using renewable energy and resources more
In this programme, CLP developed a GREENPLUS Console for the
eco-garden and offered technical consultancy for the installation of a
PV-powered irrigation system. Both systems help the eco-garden to reduce energy
use and transform it into a truly low-carbon organic farm. CLP also donated 4
large cable drums to the school, recycling it into a ‘working table’, painted in
yellow, for use by students and visitors.
CLP is committed to supporting non-profit-organisations and the community to
improve energy efficiency and promoting eco-friendliness to the public.
