  Agenda 1. Introduction 2. Themain business drivers 3. Schools and energy efficiency 4. Lighting 5. Solar 6. HVAC 7. Energy Metering 8. Management 9. Water Conservation 10. Project examples 11. Energy efficiency – the approach
• 3.
  Main business drivers Hugerises in energy and water – doubled in 5 years – due to “investment” in energy network High maintenance costs Buildings – poor energy efficiency Technology and capability developments
• 4.
  Rising energy costsdon't mean rising bills! Rising energy costs don't mean rising bills The technology is already here, application and a holistic approach are key The cheapest unit of energy is the one you never use
• 5.
  Schools and energyefficiency Buildings built before 2006 most inefficient Little control of usage/services left on Poor visibility of usage/reliance on bills Old, outdated, inefficient lighting, heating, cooling Incorrect tariff structures – Maximum demand No master plan – ad hoc construction No dedicated engineering team Large energy usage 100k + Sustainable/environmentally conscious organisation Long periods of vacancy

  Lighting – LEDleading the way LED lighting has come of age Carefully consider LED upgrades – Glare, colour, intensity LED retrofits should be avoided – old fittings fail in time negating the long life of LED Controls should be included – Occupancy, time based, centralised Choose reputable brands. Only select products that offer long warranties – If it last 30K hours, shouldn’t the warranty be better than 2 years??
• 9.
  Solar – Letthe sun shine Free energy Cost has reduced over the past few years Caution should be used when considering installation company Solar PV systems need to be engineered - Don't over size system Solar should always be considered with other energy saving measures Variety of installation configurations
• 10.
  HVAC – Keepingyour cool Heating, Ventilation, Air Conditioning Consider small reverse cycle units with a high COP rating Set temperatures for comfort – 22-23 C Install controls when installing heating and air-conditioning systems – Occupancy sensors, door switches Develop a lifecycle replacement program for R22 refrigerant units Undertake regular servicing of air conditioning and heating units
• 11.
  Metering – Showme the money!! Information when and where you need it Allows you to pinpoint areas of unusually high energy consumption and respond immediately Validates activities and improvements with real time data.
• 12.
  Water conservation –Making every drop count Did you know that for every litre of water, you pay to dispose of 0.9 litres into the sewer? Water is an essential resource that should NOT be wasted Most water waste can be attributed to poor maintenance – leaks at appliances and underground networks Reduce, re-use, recycle – low flow toilets, taps and showers Rain water harvesting should be part of every site Greywater recycling greatly reduces mains water use Watering should be done late evening to minimise evaporation
• 13.
  Ongoing management All energyconserving measures need to be monitored Ongoing “tuning” maximises your investment made in energy saving initiatives 0 50000 100000 150000 200000 250000 300000 1 2 3 4 5 6 7 8 9 10 11 12 2013 2014 2015

  South Australian school,based in the Adelaide foothills over 6.5 hectares, established in 1954, offering tuition from beginners to Year 12. Programmed introduced significant multi building efficiency measures including: •Sub metering system to monitor electrical performance •Lighting replacements resulting in 55 per cent energy and maintenance savings •Review of the sub-optimal air conditioning system •Installation of additional solar PV arrays The upgrades were cost neutral – the energy savings paid for themselves. The efficiencies complemented the college’s building master plan Opportunity was provided for student and teacher engagement
