SR98 Energy use in NZ households - report on year 4 of the Household Energy End-Use Project (HEEP) (2007)

This report covers some of the activities of the 4th full year of the Household Energy End-use Project (HEEP).

The project was established in late 1994, with monitoring commencing in late 1995, as a long-term research activity to create and make available a scientifically and technically rigorous, up-to-date and public knowledge base of energy use and end uses, energy services provision and key occupant, building and appliance determinants in New Zealand residential buildings.

The Year 4 activities have seen the HEEP database grow to more than 100 houses. Key data logging techniques are now developed, implemented and proven to be successful. Data processing mechanisms have been developed, and the data are now available in a format permitting rapid and in-depth analysis in future years. Year 4 analysis includes improved profile analysis and correlation of the ALF3 energy use model with actual energy use.
