Case studies

Setting and implementing an energy management policy has helped ANZ National Bank achieve significant energy savings.

Part of their energy management programme, evaluated the lighting used in their premises. Installing more efficient lighting tubes has created a direct energy saving worth around $50,000 a year. Further savings were achieved in electrical maintenance, where costs have dropped from $150,000 a year to around $10,000.

Canterbury Laundry Service replaced two steam powered dryers with LPG direct fired dryers and cut its annual energy costs by $46,000.

The move also cut the company's CO2 emissions and boosted its operating capacity.

The Lazy Shag backpackers in Kaikoura has had a multi-oil clean burn boiler installed to supply the hostel's hot water, slashing the business's electricity bill.

The boiler is fired with used cooking oil purchased at low cost from other local businesses. The reduction of the backpacker's carbon footprint sits well with Kaikoura's, and the country's clean green image.

Three companies - Monaghan Plastics, Tru Design Plastics and Tru-Test Limited - installed all-electric moulding machines.

The new machines used 9% less energy than hydraulic machines when making products with short cycle times, such as medical clips. But energy savings of nearly 80% were possible with products requiring longer cycle times, like electric fence insulators.
