Energy consumption of a representative household in Ma'anshan city was measured from March, 2010 to February, 2011. Various measurements were carried out in this study, including the total electricity consumption and the electricity consumption of lighting, three air-conditioners, a refrigerator, a washing machine, a TV set, a computer, one kitchen, and two bathrooms. Gas consumption, outdoor and indoor temperature and relative humidity were also tested. The record periods of electricity consumption, gas consumption, temperature and relative humidity of outdoor and indoor air was one minute, five minutes and thirty minutes respectively. Based on the field measured data, the total energy consumption, the structure of end-use energy consumption, the hourly variation regularity of the lighting load was analyzed. The results may aid in grasping the hourly changes of building energy consumption, understanding the characteristics of residential energy consumption, and providing benchmark experimental data for building energy simulation.
