It is Z Energy’s aim to be one of New Zealand’s shining lights when it comes to sustainability – so where better to start than a project to reduce the energy consumption of its retail lighting?

Sustainability Manager, Gerri Ward, says Z has set some really ambitious goals, with a focus on reducing waste at its retail sites and making operations more efficient.

A critical area for consideration was Z’s retail electricity use. Forecourt power and lighting alone accounted for more than a quarter of Z’s total retail electricity use.

“By changing out all of the external lighting in service station canopies with energy-efficient LED lighting, we reduced electricity consumption, cut carbon emissions and demonstrated to our staff and customers that taking sustainability seriously is not only better for the planet, it can save you money,” says Ward.

In 2014, Z partnered with Philips New Zealand to install 2200 state of the art energy efficient LED light fittings with intelligent lighting controls in 171 retail sites across New Zealand.

The defining aspect of this project is its size and scale. Z invested $2.7 million into the six month project, along with support from EECA BUSINESS.

Initial results based on data from 19 completed sites shows that the project is delivering an average 68% lighting energy savings through direct load reduction.

Further energy savings have been achieved through intelligent lighting controls, such as occupancy dimming. The current results alone account for an estimated 6% less energy usage across the retail network in the first three months of operation.

Philips have also identified an expected CO2 saving as a result of the project of up to 490 tonnes per year, over 10 years (being the expected life of the fittings). This represents a 16% reduction of carbon emissions from retail operations.

Ward says the project also improves visual comfort and safety at service stations by providing much better and more uniform light quality.

“Site staff and customers have told us the new lighting has helped them feel safer and see better at night, further enhancing the 'Z experience'.”

On the back of the successful roll-out of this retail programme, Z has undertaken a canopy lighting upgrade project across its truck-stop network in this financial year.

Z’s determination to shine light on its sustainability goal demonstrates how energy efficiency can help fuel your business and improve the customer experience.
