This study aims to monitor the electricity consumption of a hybrid ventilated single-family household over one year, focusing on seasonal variations, peak load consumption and the impact of specific appliances on total energy use. The electricity data of the monitored house was collected using intrusive load monitoring at finer time intervals at household and appliance levels. The appliances monitored include an air-conditioner, geyser, television, refrigerator, kettle, dishwasher, washing machine, oven, water purifier, mixer, grinder, and space heater. Furthermore, the monitored data was analysed to identify trends and patterns in annual electricity usage. The findings indicate that total electricity consumption peaks during the summer and winter, primarily due to increased usage of cooling and heating systems, respectively. The refrigerator and geyser accounted for a significant portion of the household’s annual electricity consumption among the monitored appliances. Moreover, it was observed that the refrigerator and geyser were used frequently throughout the year, while the air conditioner and the space heater were used only in the extreme summer and winter, respectively. In summary, this study provides a methodology to monitor and evaluate the electricity consumption in a house. It also discusses a method to study the seasonal variations and the impact of household appliances on annual electricity consumption.
