Water management in schools

Is your school water efficient?

• A water efficient primary school uses between 3-9
  litres a student a day
• A water efficient secondary school uses between
  9-12 litres a student a day

4
How much does water cost?

• water costs 2.01 a kilolitre
• Schools also pay for waste water.
• Sydney Water has info sheets on how to read water
  bills and undertake a water audit.
• Undetected leaks in schools can
• account for up to 70 of water use.

Where is water used in schools?

Educating and managing for water efficiency

• School water management can be
• Improved by
• Analysing water bills and determining school
  water efficiency eg via a water use calculator
  and DEC benchmarks.
• Conducting a water audit eg Sydney Water has a
  DVD on how to do it.
• Regular monitoring of the meter to check for
  leaks templates are available through Asset
  Management/Curriculum websites and through Sydney
  Water
• Other initiatives?
• Note Stormwater can also be a
  sustainability issue in schools leading to direct
  impacts on local waterways. Stormwater can be
  managed and taught as an aspect of waste or water
  education by conducting a stormwater drain audit,
  spraying positive signs on drains, conducting
  litter surveys and educating students about where
  waste goes.

School water saving actions

• Improve school water efficiency by
• Reporting and fixing leaks
• Using water from a tank to irrigate and flush
  toilets
• Mulching gardens
• Monitoring meters
• Using a smart meter (eg Watersave)
• Putting water saving signs in toilets
• Upgrading and modifying water appliances

Water efficiency education programs

• Observatory Hill EEC -Water Wiseguys program

See Observatory Hill EEC and Sydney Water website

Energy management in schools
10
Energy costs

• Electricity is a major cost for schools, and like
  domestic electricity, costs are set to rise.
  Items like smartboards and the DEC laptop rollout
  are contributing to rising energy cost.
• For example, a connected classroom costs 800 per
  year to run and 24/7 and would emit 5,000 kgs of
  C02. The controls console would cost an
  additional 400 pa.

Energy Benchmarking

• NSW DEC Energy efficiency electricity
  consumption
• Total average - 1.78kWh per student per day
• Total average per head - 359 kWh per annum
• Primary school average 278 kWh per student per
  year
• Secondary School average - 442 kWh per student
  per year
• Each 100 kWh of electricity 100 kg of CO2
  (greenhouse gas)

12
Energy Efficiency

• Greenhouse gas emissions have implications for
  Climate change. The Heat is on DVD is available
  for all secondary schools and through Observatory
  Hill EEC Website
• Energy benchmarking Webgraphs are available
  from Energy Australia
• Watts Workout
• Lighting audit - Light meter
• Holiday shutdown guide
• Be cool not cold- aircon guide

13
Webgraphs supplied by Energy Australia enable
the Bill Busters to monitor the success of the
WOW Plan!
With our increased use of technology enhanced
learning, we need to consider how we can support
DECs targets to reduce our schools carbon
footprints?

Energy efficiency strategies

• Lighting audit lets you know if rooms are over
  lit so excess bulbs can be removed
• Monitoring school Webgraphs a visual
  representations of how much energy is being used
• Holiday shutdown guide

15
Course activities
Powermate a device which shows the kilowatt
hours of appliances
Watts Workout a game to show how much energy
different appliances use?
16
Energy efficiency education programs
There are opportunities to use the DEC
Sustainability Action Process in energy
efficiency programs like

• Watch Our Watts Observatory Hill EECs Energy
  Efficiency program
• Carbon Kids - CSIRO
• Climate Clever Energy Savers A DEC energy
  efficiency program
