Sky Tower, Sky City, Auckland
The company was wanting to have a reduction on energy consumption from lighting, so they hired Jonathon Wood Bridge-Buys an energy and environmental engineer to help assist in achieving their goal.
- Before the project they were using 40million kWh’s per year
- 1.3 million was spent on the lighting project, they have saved 4.5 million in two years from the implementation of this plan.
- They have also saved between 50-80% on electricity due to an upgrade of all lighting from, halogen to CFL in their corridors, lifts and lobby’s. As well as using light tubes in the carpark, and the use of LED technology for the tower.
- The project was completed in 2009
- Qualmark enviro gold was awarded in early 2010
Since the completion of that project Sky City has also begun to look into more energy efficient ways for heating and cooling.
- Solar panels installed to preheat water during the day.
- They have also placed a wind turbine on top of the tower, with the help from Vector.

Hassle Free Tours, Canterbury
Has been run by Mark and Nikki Gilbert since 2003, they operate day long; Alpine Safari, Jet Boat adventures and Lord Of The Rings location tours.
The owners have always shared a passion for conservation, so when they began their business they immediately looked into other options other than the use of diesel to fuel their vehicles. So they came across Bio fuel to help reduce their carbon footprint.
So they Contacted Toyota in regards to changing their vehicles to Bio fuel and received no support in Toyota.
They then took it upon themselves to trial out the Bio fuel on their on personal vehicle a Toyota Prado, and had a great success. In 2007 they done the change over of all their company vehicles to Bio fuel, which cost the company $5000.
Since the change over they have:
- Reduced their companies green house emissions by 15-18%
- Gained free marketing of their business through newspaper and television interviews
They are currently aiming to change their vechiles from Bio fuel 20 to Bio fuel 100 during the summer.
