The One Tonne Life project was started and sponsored by Swedish wooden home builder A-hus, renewable energy firm Vattenfall and car maker Volvo. Designed for a four person family, the One Tonne Home is an experiment in low carbon living.
The home includes many hallmarks of solar passive design, including a tight building envelope, thick insulation, shaded windows, and a strong insulating foundation. These measures ensure that the home can be powered completely by thin-film solar panels on the roof of the house and the carport. The home will be built by A-hus, whose goal is to build climate-smart wooden houses.
