house energy consumption

According to the local climate in Auckland, New Zealand, a house does not normally need any active cooling controls such as air conditioning or ceiling fans during the summer. Temporary heating is mainly needed during the winter night. In addition, winter daytime window ventilation is required to remove moisture arising from daily occupant activities. A previous study (Su, 2008) showed that additional winter energy consumption is needed for space heating, for hot water heating and for other appliances that are impacted by the winter conditions.
