Commercial Solar and LED Stunning Success
A national retailer has had stunning success with the roll out of just 2 of the 7 demand management and energy efficiency measures identified and quantified by Water & Energy Savers staff.

Annual savings of $5,747,987 (34%) will be achieved by just rolling out 2 measures Solar PV Systems to replace peak (day time) power usage and energy efficient lighting.

Payback periods for Commercial Solar PV Systems range from 2.65 years to 3.9 years depend on local tariffs and which state the stores are located.

Energy efficiency lighting systems payback periods vary from 2.19 - 3.17 years per store.

From energy efficiency and demand management priority viewpoints the 7 tactical and strategic priorities identified are:

Efficient lighting systems and upgrades 92% of sites
Solar PV systems 68% of sites
Sub metering 43% sites,
Tariff re-negotiations 3 states
VSD drives - 32% sites
Air conditioning system upgrades 36% sites,
Building Management Systems 22% sites

Pointing Solar East and North Maximises Savings
Pointing the 32.5 kW Solar PV Systems both east and west has maximised savings and solar generation use for Woodlands Winery at 3948 Caves Road, Wilyabrup WA.

The winery starts work at 6.00 am in summer and 7.00 in winter. The east facing solar panels start generating electricity at sunrise replacing grid power electricity.

Water & Energy Savers , Managing Director, said " This is a great example of of an engineered solar solution we designed the Commercial Solar PV System to meet Woodlands Winery requirements and maximising the savings available."

You can see the east facing portion of the Commercial Solar PV System as walk up to the cellar door to try the fabulous Woodlands wines.

Water saving facts
Dandenong Hospital and Monash Medical Centres Clayton & Moorabbin

2006/2007 Water Consumption 314 million litres
Annual water cost $582,000
Estimated annual water savings 30 million litres
Reduction in annual water consumption 9.5%
Annual cost savings $83,000
Estimated future annual cost savings >$200,000
Implementation costs incl. audit fees $106,000
Payback period 15 months

The brief

With the support of Southern Health’s Senior Engineering Manager, Russell Crook, Water and Energy Savers conducted detailed onsite water audits at Monash Medical Centre Clayton, Monash Medical Centre Moorabbin and Dandenong Hospital. Water asset registries were first established, which not only allowed baseline water usage to be assessed, but provided a key tool to plan future water infrastructure expansion and to minimise operating costs.

Water and Energy Savers then examined every water-using appliance and piece of equipment, ranging from showers, basins and toilets, to boilers and cooling towers as well as central sterilising services and laboratories. It was identified that significant water savings could be achieved by making simple, low cost and low risk changes to existing water infrastructure.

The savings

Water savings were estimated to be 30 million litres per year, or just under 10% of the combined annual water consumption.

Equally important, the combined annual cost savings in water and associated waste and energy usage were estimated to be $83,000 based on 2006/2007 water pricing. With the cost of water expected to increase in the coming years, annual cost savings could well exceed $150,000 over the next five years*.

* As stated by Premier John Brumby on August 14th 2007, “... we indicated that water prices would approximately double over the next five years ...”

Implementation challenges

Particular attention was paid to minimising disruptions to hospital staff, patients and visitors, as well as the water supply itself. Awareness of hygiene and infection control requirements was also of critical importance.

Water and Energy Savers, with major experience in designing and project managing large and complex water and energy conservation programs, assisted Southern Health to meet these challenges head-on. All water saving recommendations were implemented in less than a week for each medical facility!

The combined total implementation and audit cost was $106,000. With annual water savings of just under 10% and annual cost savings of $83,000, the financial payback period is less than 15 months!

Benefits all-round

With simple, quick-to-implement & low cost water infrastructure changes, Dandenong Hospital, Monash Medical Centre Clayton and Monash Medical Centre Moorabbin achieved substantial water and operating cost savings. This has not only benefited the Centres themselves, but has contributed to community water conservation efforts in general.

And it doesn’t stop there. Water and Energy Savers is monitoring water consumption to quantify the actual water savings – initial results already indicate a 15% reduction in water usage.

As Russell Crook stated “Monash and Dandenong have shown that significant and sustainable water savings can be achieved without major effort and cost. Expanding these water efficiency gains throughout Southern Health is now a realistic goal.”
