家庭能源消耗的分析通常涉及技术系统和人们行为的描述。这项工作的重点是人类活动、电器使用和电力消耗之间的关系。它依赖于对法国 60 个家庭的独特样本应用各种测量工具。总体而言，调查问卷、日记和测量的消耗量对所研究的三种电器的使用强度和时间提供了一致的描述。然而，根据所研究的指标和设备的不同，发现了一些变化。从日记和消费中得出的活动水平显示出很大的差异。然而，它们可以基于对活动性质差异的合理假设来解释。最重要的是，三种测量工具之间家庭使用强度的变化是一致的。这一结果可以部分描述使用频率和持续时间、电器功能和节能举措在最终能源消耗中的作用。在方法论上，本研究表明，问卷可以提供有关家庭能源消耗相对水平的一致信息，而日记则提供有关能源消耗时间的可靠信息，支持使用大规模和广泛的“时间使用调查”来模拟欧美电力需求的多样性。
The analysis of household energy consumption usually involves the description of technical systems and of people behaviors. This work focuses on the relationship between people activities, appliances use, and electric consumption. It relies on the application of a wide range of measurement tools on a unique sample of 60 households in France. Overall, questionnaires, diaries, and measured consumption provided a consistent description of the intensity and time of use of the three appliances studied. However, variations were found, depending on the indicator and appliance studied. The levels of activity derived from the diaries and consumption show large differences. However, they can be explained based on reasonable assumptions on the differences in the nature of the activities. Most importantly the variations in the intensity of use across households are consistent among the three measurement tools. This result allowed a partial description of the role of the frequency and duration of use, appliances features and energy saving gestures in the final energy consumption. In terms of methodology, this study shows that, questionnaires can provide consistent information on the relative level of energy consumption by household, while diaries provide reliable information about when this energy is consumed, supporting the use of the large scale and wide spread “Time Use Surveys” to model the diversity of power demand in Europe and America.
