Energy Efficiency - Refrigerated display cabinets sold and their average energy consumption 2005–2024

Through the Equipment Energy Efficiency (E3) Programme, New Zealand and Australia develop common energy efficiency measures to regulate the energy performance of products in both countries.
Suppliers of products regulated under the E3 Programme provide Energy Efficiency and Conservation Authority with annual sales data for the period of 1 April to 31 March. This is used to help measure the shift in product efficiency over time and to calculate the energy savings to date from these improvements in energy efficiency.

通过设备能源效率（E3）项目，新西兰与澳大利亚共同制定了一系列能源效率措施，以规范两国产品的能源性能。根据E3项目的规定，产品供应商需向能源效率与节约管理局提供从4月1日至3月31日的年度销售数据。这些数据被用于衡量产品效率随时间的转变，并计算自能源效率提升以来所实现的能源节约。
