SR495 Household Energy End-use Project 2 Report on winter comfort, heating and indoor temperatures (preliminary analysis) (2024)

The Household Energy End-use Project 2 (HEEP2) is a comprehensive national study of energy use and conditions in New Zealand homes designed to replicate the earlier HEEP1 study undertaken in 1999–2005. HEEP2 involves a national sample of over 750 households with data collected in various ways, including self-completion and on-site surveys, in-home monitoring and accessing metered energy data from retailers.

This report presents the first insights from some survey and monitoring data, focusing on winter heating, comfort and internal temperatures. The survey data is derived from the in-home interview and building and appliance survey completed for 425 households throughout the country. The detailed temperature analysis is based on a subset of 125 of these households monitored over winter 2023. As this represents less than half the HEEP2 monitored sample, these results are preliminary only.
