This beautiful One Tonne 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 Tonne Life" - the goal of the project is to see if a family of four can reduce their carbon footprint from 6-8 tonnes of CO2 per person down to one tonne per person.
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.
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. The goal of the project is to reduce the average Swede’s carbon emissions from six to eight tonnes of CO2 per year down to just one tonne by placing the family in an energy-smart house, with an electric vehicle and a source of clean electricity. Do you think you have what it takes to live a One Tonne Life?
