The Household Energy End-use Project (HEEP) is a multi-year, multi-discipline, NewZealand study that is monitoring all fuel types (electricity, natural gas, LPG, solid fuel, oil andsolar used for water heating) and the services they provide (space temperature, hot water,cooking, lighting, appliances etc). The monitoring of 400 randomly selected houses will befinished in early 2005, with a national residential sector energy model to be completed in 2007.The paper provides a brief background to the study and an overview of the monitoringmethodology, along with preliminary results based on measured data from 200 houses. Ithighlights some initial findings and discusses the type of issues that can be investigated withsuch a comprehensive, integrated database including energy use, house physical characteristics,and socio-economic data. Examples include household energy uses, hot water standing losses,low-flow shower heads, the impact of thermal insulation on space temperatures and energy use,and uses of different heater types.
