结果是从英国住宅建筑的样本的电力消耗的监测研究。五分钟的平均全屋耗电量记录72个住宅在5个网站在2年的监测期。从监测的第一年到第二年，家庭的平均年用电量显著增加了4.5%（t = 1.9; p < 0.05，单尾）。开发了新技术，根据对五分钟监测数据的分析，估计不同电器组的用电量。整体用电量增加，是由于“备用”电器（如电视及消费电子产品）的用电量增加10.2%，而“活动”电器（如照明、电水壶及电花洒）的用电量则增加4.7%。还调查了不同能源用户群体（低、中、高）的消费情况，并确定低和高用户是消费总体增加的原因。需要进一步的调查，如定量和定性研究，以提高对家庭用电的理解进行了讨论。(C)2007 Elsevier B.

Results are presented from a monitoring study of the electricity consumption of a sample of UK domestic buildings. Five-minutely average 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. (C) 2007 Elsevier B.V. All rights reserved.
