Te Papa's energy management team has cut energy costs while taking care of a huge open-plan building with constantly changing uses and ever-expanding operating hours.

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'.

A programme of energy audits for tourism operators identified annual cost savings averaging 15% - and many of the measures could be implemented for little or no cost. The modern Novotel Auckland Ellerslie already had energy saving initiatives, but its audit showed it could save even more - without costly investment.
