Creating a love and awareness of
the environment in children was one of the basic principles
Greenwood Independent Primary School was founded on. The school
is registered with the Eco-Schools program which is supported by the WWF-SA and WESSA and endorsed by
the Department of Education. This international program assists
schools in encouraging curriculum-based action for a healthy
environment. The school involved chooses three focus areas
and develops lesson plans; school improvement plans and records
their progress in a portfolio. At the end of each year the
portfolios are assessed and successful schools are awarded
a green flag. As one of over 15 000 schools in this initiative
world wide, Greenwood is proud to have earned a flag for two
years in a row and hopes to win an international flag next
WINS the eta 2011 Young Designers Category
Eskom and the Department of Energy are celebrating the 22nd
Annual eta Awards. The aim of the eta Awards is to reward
the proven application of sound energy efficiency principles
in the commercial, industrial, residential, agricultural and
education sectors. Energy efficiency is part of Eskom’s drive
to ensure a sustainable electricity supply into the future.
Given the significant emphasis place on energy efficiency
by the Government of SA, the Minister of Energy is the official
patron of the eta Awards.
Greenwood Independent School participates in WESSA’s Energy
and Sustainability Programme, which is funded by ESKOM. The
young team at Greenwood, in Plettenberg Bay, examined the
relationship between the climate, building design and energy
usage. Their aim was to see what they could do, through research
and recommendations, to influence local municipality officials
to more efficiently design and build their RDP houses, for
maximum energy efficiency.
The team looked at how RDP houses are currently designed,
taking field trips to local townships to look at house construction
and to identify ways to make them more energy efficient. Through
a series of experiments back at school, they found that RDP
houses had no insulation meaning that precious heat would
escape through the roofs and windows heat would escape through
the roofs and windows, and so alternative, often more dangerous
forms of heating would have to be used such as paraffin heaters,
often the source of house fires. The team also found that
those built facing north had a temperature rise of 6 degrees
internally, compared with their west-facing equivalents, which
saw no temperature rise at all.
This innovative young team of designers from Greenwood Independent
School were invited to visit their local mayor to present
their research findings who informed them that their research
and recommendations were a real ‘eye opener’ to him personally.
He added that it would probably change the way RDP houses
in the local area would be built in the future. In fact, new
RDP houses scheduled to be built in January and February of
next year will be taking into account the findings of the
research. So, these young designers have already made a huge
impact on their local environment and on the future lives
of township residents.
Well done Greenwood!!
ETA AWARDS 2010
Eskom and the Department of Energy have for the past 20
years rewarded excellence in the field of energy efficiency.
The purpose of the ETA Awards is to reward exceptional effort
in the more efficient use of energy by individuals, students,
companies or other institutions. All of the awards comprise
a cash amount of R30 000 for the winner in each category and
R5 000 for each of the two runners-up in each category.
We were recently notified that GREENWOOD INDEPENDENT SCHOOL
is one of the 5 FINALISTS in the Young Designers Category
for their “Keep a Chill on Global Warming” entry!
Refrigerators are one of our households biggest consumers
of electricity and, with the help of Susan Donald, they have
constructed an eco fridge, which does not use any electricity!
This is the latest of our energy saving projects which started
last year with our solar water heater. The fridge works on
the principle of evaporation, just as the Zeer clay pots do.
However it is bigger, uses easily obtained and inexpensive
materials, which we can get at the local hardware store. (Shade
cloth, netting and sand.) The fridge is being used to keep
milk, water and lunchboxes cold—and in tests, lowered
the temperature of liquids by between 8 and 10 degrees.
