 Our moral education should include how to promote

         - to develop environmentally
           friendly attitude

            What can be saved

 No more leaky water taps.
 Save water!
Does your school have these things ?
Natural resources


  What kind of water ?       from flush water
                             from water taps
   Where ?                   in our school toilets

   What kind of energy   electricity
   For example :             used by
                                  computers and
    How ?

    When they ( air-conditioners, lights , computers, printers)
    are not in use
            we should
                 turn them

       Besides, we should use
          energy-saving           light bulbs and
                                 computers .
In addtion , we can re-paint the walls using suitable colours
          to reflect most light        , and so we can
             brighten the classrooms and save energy.
                                  Over use of
                             What is being wasted?
                          Do you wear these in the classroom
                          while enjoying air- con in summer?
Be mature! Be sensible!

Boys should respect girls.
The temperature of the air-conditioners
       should be adjusted
                         to    25 °C
To save water      ,
    we can use

          infrared sensor operated
                faucets / water taps
                       to replace
                             leaky water taps
       we can use modern water closets
         dual flush device which
           allows users to choose the volume of discharge ,
             such as half-flush or full-flush .

School refurbishment
      To reduce tree cutting ,
            we should use less paper
                      printing on both sides of the page.
                               Many teachers don't mind if you
                               turn in a paper like this-- just ask
 Bookmark / keep the data by using email
   Also, you can consider cutting down on the things your print out.
   Do you really need to print out that web page, or can you just
   bookmark it or keep it by using email?

What’s more, we can use some
handkerchiefs to replace paper tissue.
What are those things that can pollute our school environment ?
E.g. Lunch boxes made of        foam rubber           and

     non eco-friendly stationery products
            such as correction fluid ,

    We should replace this kind of disposable lunch boxes,
                       plastic chopsticks, spoons and forks.
         washable and reusable products .
  Plastic bags Where ?
  Our school tuck shop
The school or Student Union should advise our
tuck shop to replace plastic wags with
recyclable and hygienic brown paper bags.
By simply reusing or recycling your
Christmas decoration, wrapping
paper and cards you will be able to
help reduce the million tons of
holiday garbage created each year.
Printer ink
Many printers have multiple settings or print quality.

We can use the high high quality setting

                                     for things that have to look nice,

   but use the low quality setting
                                     for things that don't.

         Heating & Cooling

         Geothermal systems
         transfer heat
         between the ground
         and a building.

         Heating & Cooling

         In the cooling mode
         they absorb heat
         from the building
         and transfer it to
         the ground.

         Typically they do
         this by circulating

The Geothermal Heating and Cooling
is a closed loop heat pump system with
384 bore holes, 450 feet deep located
over the playing fields and parking lot
and serves the high efficiency water
source heat pumps located in the
elementary wing. Energy recovery
units re-capture exhaust air
temperature to provide energy savings
and comfort.
Roof mounted photovoltaic panels
generate a maximum of 25KW of
electricity in a grid connected
Power is also “Net-Metered” so that
the school can benefit from selling
electricity back to the Utility
provider when excess power is
Atrium 天井 and stair light wells, as
well as sunscreens, will be utilized to
control the natural light into spaces.

Daylighting systems reduce the need
for electric light thereby lowering the
overall electricity usage costs while
allowing the air conditioning system
to be reduced in size.
