Case Studies

Kimba IGA

The IGA at Kimba has significant costs associated with its energy consumption mostly caused by refrigeration needs. Our audit recommended lighting upgrades, power factor correction, reduction in cooling loads and solar PV. Savings could see a 25% reduction in energy costs.

Barossa Quarries

After undertaking data logging at the quarry site, we recommended installation of 100kW solar PV, power factor correction equipment and smart switching of diesel generators.  These recommendations, costing approximately $150,000, save the owner around $40,000 per year. 

Hotel Group

Our audit and data logging helped the owners of a large hotel group to create a business case to upgrade the efficiency of their air-conditioning and lighting.  Education of the hotel staff and subsequent behavior change resulted in a further 8% energy reduction.
