Case studies

Coldstorage International used a powerful analytical tool to reduce energy bills by one third.

By re-evaluating long-established operational processes they managed to reap a $90,000 energy saving annually for a project outlap of around $12,500 - a seven-fold return in one year.

The University of Waikato will get the best energy performance from the University by running it like a well-tuned engine. An energy performance contract with Honeywell has proven a cost-effective tool saving them $173,000 in the first year alone.

You can talk the talk, but what do you actually do to manage energy better?

ASB Bank has found a path that rewarded it with energy savings of nearly $200,000 in 2008, one step towards a targeted $1m annual saving.

This case study looks at how this dynamic organisation has made energy efficiency integral to its business.
ASB has taken a measured approach, following a cycle of ‘plan, do, review and learn'.

Fishing goes back to the future

Switching from trawling to anchor seining has cut Motueka skipper Ken Franks' fuel bill by more than half.

Since converting his 15m boat the FV Vanguard from a trawler to an anchor seiner in 2008 his catches sizes have increased too, and the quality of the fish is better. That means higher profit margins for Mr Franks at a time when rising fuel prices are forcing others in the industry to think about tying their boats up.

Mr Franks is now encouraging other trawler skippers to do the same.
