    Crowne Plaza Christchurch's utility spend is a significant overhead. The driver behind an energy review was a desire to reduce utility costs - without compromising guests' comfort.

    An energy audit uncovered ways to cut consumption and also kick-started a change in thinking. "It became part of our everyday business," explains chief engineer Chris Stevens.

    The hotel's annual electricity bill is $100,000 less now than in 2006 - a 14% saving. It also achieved a peak annual saving of 14% in potable water and trade waste, and 12% in LPG consumption.
