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

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

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Old, outdated, inefficient lighting, heating, cooling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

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??

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

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

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.

Water conservation – Making every drop countDid 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

Ongoing management

All energy conserving measures need to be monitored

Ongoing “tuning” maximises your investment made in energy saving initiatives

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 paybackSt Brendan Shaw, Devonport – 31% energy reduction, 4.5 year paybackPrince Alfred College – 60% lighting energy reductionSA Police HQ – 84% daytime / 94% night time energy reduction

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 planOpportunity was provided for student and teacher engagement

Actual ProjectsSt Andrew’s school, Adelaide – 24/7 monitoring picked up the below anomaly
