Energy usage of households accounts for a significant portion of total energy consumption and CO2 emissions. It is therefore a critical task to efficiently manage and minimise energy usage in housing in order to meet carbon dioxide (CO2) emission reduction and energy consumption cut targets.
The minimisation of energy consumption in households has been achieved through promoting the delivery of low-energy housing, the operation of energy efficient domestic equipment and the practice of occupants’ energy conscious behaviours. However, the main challenge remains on how occupants manage the energy in homes and how occupant behaviours influence energy consumption in domestic environments. This paper focuses on investigating the relationship between human behaviour and energy consumption through analysing the energy usage collected from selected Scottishhomes equipped with a gas-electricity-water usage monitor and indoor temperature, relative humidity, and CO2 sensors. The study encompasses the analyses at different time granularities such as hourly, daily energy usage patterns. It is confirmed that domestic energy consumption is affected by the occupants’ presences and behaviours.
