Average energy efficiency ratio of heat pumps and air conditioners sold in New Zealand
Year ended March 2004–2022
|Year ended March||
Single splits: air-to-air systems with one indoor unit connected to an outdoor unit.
Coefficient of performance (COP): ratio between the heating power output and the input. The higher the ratio, the more efficient it is.
Energy efficiency ratio (EER): ratio between the cooling output and power input. The higher the ratio, the more efficient it is.
Sales weighted: weighted average of the units' energy efficiency. This average is weighted proportionally to the sales of units.
Annual energy consumption is based on assumed yearly usage.
The average is sales-weighted, which means it depends on the energy efficiency of units that were actually sold.

About this dataset
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.
Purpose of collection
The Equipment Energy Efficiency Programme is run by the Commonwealth state and territory and New Zealand governments working with industry to drive improvements in the energy efficiency of appliances and equipment to save households and businesses money on their energy bills reduce energy use and reduce emissions.
Method of collection/Data provider
The measures developed through the E3 Programme are minimum energy performance standards (MEPS) and the Energy Rating Label.
