Team Sweden's journey started in autumn 2011. In the Sustainable Building class at Chalmers four groups of students had an internal competition concerning the design of a Solar Decathlon house. In the meantime, the application for SD China 2013 was prepared and sent to the organizing committee. In early 2012 Halo won the internal competition and Team Sweden was accepted to SD China. Since then a new group of students has taken over the winning project Halo, to develop it further. The spring 2012 has been a journey of finding inspiration, developing knowledge and skills, and learning how to work as a team.
