A Measured Factor-4 House
The results of three years measurements of the power consumption of the different appliances in a low-electricity house will be presented. The house is for most end-uses equipped with state-of-the-art electric household appliances, and has all comfort and appliances as in a standard house. The total annual electricity consumption is down to 850 kWh per year, which is four times less than an average 3-persons household in Belgium. The appliances used will be briefly discussed. Based on the measurements and on statistical data of households, the influence of the residents’ behaviour versus the influence of the most efficient technology in the resulting energy use will be discussed.
