Water and energy management in schools

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

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 actionsImprove 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 for more details

Energy management in schools

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)

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

Webgraphs supplied by Energy Australia enable the ‘Bill Busters’ to monitor the success of the WOW Plan!

With our increased With our increased use of technology use of technology enhanced enhanced learning, we need learning, we need to consider how to consider how we can support we can support DEC’s targets to DEC’s targets to reduce our schools reduce our schools carbon footprints?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

Course activities

Powermate – a device which shows the kilowatt hours of appliances

Watts Workout – a game to show how much energy different appliances use?

Energy efficiency education programs

• Watch Our Watts Observatory Hill EEC’s Energy Efficiency program

• Carbon Kids - CSIRO• Climate Clever Energy Savers – A DEC energy

efficiency program

There are opportunities to use the DEC Sustainability Action Process in energy efficiency programs like:
