One Tonne Life

The companies behind the initiative

Three companies are working together on “One Tonne Life:


Wooden house builder A-hus aims to lead the development of climate- and energy-efficient housing. The goal is to make climate-smart wooden houses available throughout the market. A-hus will begin selling the “One Tonne Life” villa to the general public soon.

Vattenfall is currently involved in several projects aimed at the development of smart electricity grids and energy solutions for households, focusing particularly on the efficient use of electricity. An important part of this process is to make energy use visible in the home. In “One Tonne Life” Vattenfall is among other things providing new technology for measuring the family’s electricity consumption in real time.

Volvo Cars

“One Tonne Life” gives Volvo Cars the opportunity to study how the Volvo C30 Electric fits in with the modern family’s lifestyle. The family’s use of the car will show what is needed for a battery-powered car to be both attractive and cost-efficient to drive and own.

Home appliances stand for approximately 50% of energy consumption in a household. There is consequently a very large energy savings potential for a family to use energy efficient appliances in an eco-friendly way. Siemens contributes with innovations and new technology in the ‘One Tonne Life’ household, so that the family, considering the environment, does not compromise their own comfort. Our ambition with this project is to learn more about how much energy can be saved by correct use of our appliances, as well as obtaining ideas on how we can develop new even more energy-saving products.

During the last 15 years, Siemens has decreased our appliances’ energy consumption by an average of between 40 to 80 percent – and the figures for energy and water consumption in the most efficient products are world class.
