The Hong Kong Community College (HKCC), an affiliate of The Hong Kong Polytechnic University, provides learning opportunities for life-long development with advanced teaching facilities, serving an ideal learning environment for students. HKCC attaches a great importance to the greening atmosphere. To access more sunlight and reduce the number of lightings, glass curtain have been adopted for the campus buildings. Besides, HKCC equips the outdoor spaces with solar lights which store energy during daytime and light up automatically at night, delivering more eco-friendly performance.
The building has fully implemented a smart building management system. Pumps, fresh air cabinets and air handling units are topped off with variable frequency drive, enhancing energy efficiency which save electricity by about 20%. HKCC also installed motion sensors in some classrooms to automatically control the air conditioning system switch. Apart from energy saving facilities, the school carried out various environmental education and promotion such as putting up notices to remind students to turn off the lights on their way out.
In order to further support environmental protection, HKCC actively participated in CLP's Peak Demand Management. CLP's professional team visited the campus for inspection and provided energy audits to customise a solution, striving to maximise the environmental outcomes. During the event period, HKCC successfully sorted out the classrooms schedules to switch off vacant floors’ chillers for energy saving. This provides teachers and students with the same room temperature and comfort level without affecting the normal activities in the school.
Using electricity smartly and cutting down energy consumption timely, the school can achieve multiply benefits in terms of economy or environment. A representative from the Campus Facilities Management Office said, ‘I am very pleased that our campus can contribute a more comfortable and greener environment to Hong Kong. We will continue to support various activities provided by CLP in hopes of achieving energy conservation.’
AD & FD POHL Leung Sing Tak College focuses on cultivating students’ responsibilities as global citizens, as well as promoting STEM education to encourage creative thinking. The school has participated in the Smart Energy Saving Training tailor-made by CLP, utilising the Smart Enterprise as the learning platform. Students can therefore experience various concepts of energy efficiency and conservation to build a green campus.
CLP’s Smart Enterprise not only simplifies the energy management, but also provides technical supports to the school with optimised electricity operation system. Taking suggestions from CLP after on-site assessment, the school applied the Smart Enterprise solution by installing temperature sensors in the Smart Lab, along with the use of infrared controller and preset scene modes. Therefore, the air conditioning system can be switched off automatically to minimise energy waste. Besides, Smart Enterprise provides real-time monitoring of indoor CO2 concentration, giving access to smart control of automatic exhaust fans for energy saving.
With the in-app energy management function, students are free to access information like energy distribution chart and electricity consumption data for analysis practices anytime. Teachers can make good use of CLP’s regular energy analysis reports to carry out discussion with students, exploring possible energy saving solutions. Students can fully experience the benefits of energy efficiency in various ways, reinforcing their ability and knowledge of cross-subjects in line with the school objectives to promote the STEM education.
CLP’s professional team not only provides tailor-made energy saving solutions to schools that participated in the Smart Energy Saving Training, but also holds seminars to share environmental tips in school. Mr. Chan Ho Kit, the coordinator of STEM said, ‘I strongly recommend CLP’s Smart Energy Saving Training and Smart Enterprise to other schools. Students can apply theories to real life scenarios, unleashing their creativity for building a more energy efficient campus. It is a two-pronged achievement of learning and energy conservation, bringing great benefits to both students and environment.'
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.
