Home for Life is designed as the world’s first Active House and is a result of a research and design development aimed at ensuring a necessary foothold in architecture in an anticipated sustainable and low-carbon future.Thanks to 7m2 solar collectors, 50m2 solar cells and a solar heat pump the house has an anticipated energy surplus of 9kWh/m2/year it. In this way it takes approximately 40 years for the house to generate the same amount of energy that was used to produce its building materials and at that point the house will have returned more to nature than it consumed.The window area of the house is 40 percent of the total floor area – twice the area of a traditional house – while sensors register heat, humidity and CO2 in all rooms and automatic window opening mechanisms let in fresh air. Furthermore the occupants and environment of the house are valued through quantitative and qualitative interviews and measuring. Subsequent the values are analyzed to develop knowledge to optimize the positive impact on the occupants and climate.
