whole house power consumption was recorded for 72 dwellings at five sites over a 2-year monitoring period. The mean annual electricity
consumption for the households increased significantly by 4.5% (t = 1.9; p < 0.05, one-tailed) from the first to the second year of monitoring. New
techniques are developed which estimate the electricity consumption of different appliance groups, based on analysis of the five-minutely
monitored data. The overall increase in electricity consumption is attributed to a 10.2% increase in the consumption of ‘standby’ appliances (such
as televisions and consumer electronics) and a 4.7% increase in the consumption of ‘active’ appliance (such as lighting, kettles and electric
showers). The consumption of different energy user groups (low, medium and high) is also investigated and low and high users are identified as
contributing to the overall increase in consumption. The need for further investigation, such as quantitative and qualitative studies, to improve
understanding in domestic electricity consumption is discussed.
