Auckland Airport hopes a new energy conservation programme launched with tenants will be worth $2 million a year in savings.

As part of the programme Auckland Airport will invest more than $3 million in projects to measure and manage energy over three years.

It aims to save six gigawatt hours of energy - enough to power around 750 homes every year and worth more than $2 million.

Supported by the Energy Efficiency and Conservation Authority, the programme is the first collaboration of its type between a large-scale commercial landlord and tenants. Auckland Airport has more than 100 tenants throughout its terminals and wider business district.


In the first stage an energy monitoring system will identify energy use and potential savings in businesses across the Auckland Airport business district. Auckland Airport will work directly with at least eight tenant companies to help improve energy use, with workshops and guidance developed for the wider group.

EECA chief executive Mike Underhill said Auckland Airport was leading the way in demonstrating the business benefits of improved energy use, and forming partnerships between landlord and tenant.

Auckland Airport's sustainability and environmental manager Martin Fryer was the winner of EECA's 2014 energy leadership award.

Businesses use 70 per cent of New Zealand's total energy, worth around $8.3 billion every year.
