A new supermarket, Countdown Auckland Metro New Zealand opened its doors yesterday, featuring a range of environmental initiatives such as night blinds and energy efficient CO2 refrigeration.

The owner of the store, Progressive Enterprises, says it has been carefully designed and constructed to reduce its impact on the environment. In addition to the CO2 refrigeration system the supermarket will minimise its carbon footprint thanks to other energy-efficient lighting.
Store features
  • CO2 refrigeration system
  • Night blinds
  • Energy efficient lighting
  • 2,200 m2
  • 15,000 product lines
  • Lotto outlet and cafe
New Zealand’s first transcritical CO2 and other installations
Before the Countdown Auckland supermarket, Hastie Consulting in conjunction with Cowley Refrigeration Engineering (CRE) signed in 2011 a Design Build Contract with Foodstuffs Wellington to build the first transcritical CO2 Refrigeration System in New Zealand for their New World supermarket at Newlands in Wellington. The latter store will not only be the first in New Zealand to feature a transcritical CO2 refrigeration system, but also enable a comparison of the system performance to one of the country’s several cascade systems that is being installed in close proximity at a store of the same format.
The first (cascade) CO2 supermarket system in New Zealand was commissioned in 2006 by the owners of “The Warehouse” supermarket in Auckland. The system uses propylene and CO2 and is the first New Zealand system to use CO2 for cooling the display cabinets and cold rooms for both the low temperatures. For the medium temperatures the system uses propylene on the high temperature stage.
New Zealand and Australian bilateral initiative “In from the Cold”
In New Zealand and Australia non-domestic refrigeration equipment and systems consume approximately 7% of the total energy use in each country. The two countries collaborate on improving the energy efficient of their products under a joint programme called the Equipment Energy Efficiency (E3) Programme. “In from the Cold” is a strategy to make industrial and commercial refrigeration equipment and systems more energy efficient, prepared for the E3 programme.
Currently, in New Zealand refrigerated display cabinets must already meet minimum energy performance standards (MEPS).
