2. Agenda
1. Introduction
2. The main 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
Huge rises 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 costs don'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 energy efficiency
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Old, outdated, inefficient lighting, heating,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

Winter Holiday - NMI 8000000744

8. Lighting – LED leading 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 – Let the 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 – Keeping your 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 – Show me 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 energy conserving measures need to
be monitored
Ongoing “tuning” maximises your
investment made in energy saving
initiatives

14. Project findings
Mercedes College, Adelaide – 55% lighting energy reduction,
40% overall, fully funded/ 5 year payback.
St Peters College, Adelaide – 38% overall energy reduction, 5
year payback
St Brendan Shaw, Devonport – 31% energy reduction, 4.5 year
payback
Prince Alfred College – 60% lighting energy reduction
SA Police HQ – 84% daytime / 94% night time energy reduction

15. 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

18. Actual Projects
St Andrew’s school, Adelaide – 24/7 monitoring picked up the below anomaly

19. Programmed Sustainability
Identify – initial review
Evaluate – through an independent,
unbiased and holistic energy study
Execute – agreed efficiency measures
Realise – measure, verify, maintain
Unbiased, holistic, vendor independent
