Z Energy has recently partnered with Philips on an innovative lighting project to reduce its energy use and carbon footprint.
Z Energy has set a series of ambitious goals to ensure its business is more sustainable, with a focus on using 10% less electricity across its retail network, and reducing the carbon footprint of its convenience stores by 10%.
To achieve this, Z has replaced the under-canopy lighting in all of its service stations with LED fittings.
Z partnered with Philips NZ to roll out a phased programme, installing 2200 high-end energy efficient LED light fittings with intelligent lighting controls in 171 retail sites across New Zealand over a six month period.
The project was designed to achieve operational energy and maintenance savings for the network, and consequently reduce carbon emissions.
The first phase of the project began in September 2013. Initial results based on data from 19 completed sites show that the project is delivering an average 68% lighting energy savings through direct load reduction. While further energy savings have been achieved through intelligent lighting controls such as occupancy dimming, the current results alone account for an estimated 6% less total energy usage across the retail network in the first three months of operation.
As well as the power savings, the project has improved visual comfort and safety at Z service stations, by providing better light uniformity and lighting quality. Site staff and customers at the completed sites have reported the new lighting has helped them feel safer and see better at night.
“The defining aspect of this project is its size and scale. Z is determined to lead the way on retail operational sustainability. Identifying and initiating large-scale energy efficiencies is critical to the integrity of this stance,” says Gerri Ward, Z Sustainability Manager.
Philips has identified an expected CO2 saving as a result of the project of up to 490 tonnes per year, over 10 years (the expected life of the fittings). This represents a 16% reduction of carbon emissions from Z’s retail operations.
“The simultaneous nationwide roll-out of the programme within just six months, and the scale of the emissions savings as a result, is what really sets this project apart,” Gerri says.
Z is also undertaking a canopy lighting upgrade project across its truck-stop network during this financial year.
