SR155 Energy use in NZ households - report on year 10 of the Household Energy End-use Project (HEEP) (2007)

This is the 10th annual report on the Household Energy End-use Project (HEEP). HEEP is a multi-year, multi-discipline, New Zealand study that has monitored all fuel types (electricity, natural gas, LPG, solid fuel, oil and solar used for water heating) and the services they provide (space temperature, hot water, cooking, lights, appliances etc). Data collection was completed in 2005. This report gives an overview of the HEEP project including:

• importance of collecting data
• a review of energy end-uses
• social impacts on solid fuel use
• temperature and energy use in Māori HEEP households
• fuel poverty
• analysis of summer and winter indoor temperatures
• standby and baseload electricity use
• analysis of energy use in pre-1978 and post-1978 houses
• faulty refrigeration appliances
• electricity power factors
• the development of the HEERA model
• the HEEP appliance ownership model
• a brief international comparison of DHW systems.

Detailed tables provide estimates for appliance standby power and energy use as well as for national and regional energy consumption.
