在宣布COVID-19大流行和美国各地病例增加之后，由于该国试图控制病毒的传播，数百万人的典型日常生活被打乱。因此，房屋变成了临时办公室、教室、餐厅和娱乐中心。随着住宅建筑使用方式的这些变化，已经进行了调查和网格级研究，以了解由于大流行而导致的能源使用变化。但是，在家庭一级审查能源使用影响的努力有限。在这项研究中，分析了高分辨率的分类数据，以衡量2018-2020年225个住房单元中与暖通空调负荷、非暖通空调负荷和整个家庭负荷相关的用电量变化。分析的主要发现表明，在居住者通常不在家的时期，用电量会增加。上午10点至下午5点之间，非暖通空调住宅负荷的增幅最大；与前几年相同的平均日温度相比，HVAC负荷的总日消耗增加了。此外，将数据按家庭收入划分，最低收入和高收入家庭的消费增幅较大，而中等收入群体的消费增幅较小。
Following the declaration of the COVID-19 pandemic and the rise in cases across the United States, the typical daily routines of millions were disrupted as the country attempted to control the spread of the virus. As a result, homes became makeshift offices, classrooms, restaurants, and entertainment centers. With these changes in how residential buildings are used, surveys and grid-level studies have been conducted to understand how energy use has shifted due to the pandemic. However, there are limited efforts that review the impact of energy use at the household level. In this study, high-resolution, disaggregated data is analyzed to measure the shifts in electricity use related to HVAC loads, non-HVAC loads, and whole-home loads in a comparison of 225 housing units over the years of 2018–2020. Key findings from the analyses indicated increased electricity use during periods that occupants would usually be away from home. The most percent increases in non-HVAC residential loads occurred between 10 a.m. and 5 p.m.; HVAC loads increasing in total daily consumption compared to the same average daily temperatures of previous years. Additionally, dividing the data by household income, the lowest income and higher income households experienced the larger increases in consumption, while the middle income groups experience smaller shifts.
