The One Tonne Life Project home was designed by Gert Wingårdh, as an experimental test house for low-carbon living. The two-story home makes the most of its small footprint and utilizes solar passive design to maintain an extraordinarily degree of energy efficiency. Soon a lucky family will move into the super energy-efficient home in Hässelby to see what it takes to live a “One Ton Life” – the goal of the project is to see if a family of four can reduce their carbon footprint from 6-8 tons of CO2 per person down to one ton per person.
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.
Inside, energy efficient appliances, LED lighting, energy monitoring, daylighting, and a specialized recycling and waste management system help to reduce the environmental impact of the family. The family chosen for the experiment will also receive a Volvo Electric C30 that can be fully charged in 8 hours using the home’s solar panels and a home charging connection made by Vattenvall. During the experiment, the family is expected to go about their normal day-to-day lives including work and school, and they will be interviewed and filmed about their experiences
