Solar Decathlon China 2018
The Solar Decathlon is an international competition which was launched in 2002 by the US Department of Energy. In 2018, 20 student teams from all over the world will meet in Dhezou, China, to design and build a house which meets energy and environmental standards. The projects will be assessed by a panel of experts on the basis of 10 criteria: architecture, market potential, engineering, communication, innovation, water, health and comfort, appliances, home life and energy.
The only French team in the competition, Team Solar Bretagne brings together students, lecturers and experts from Rennes' universities, ENSAB (Rennes School of Architecture), INSA Rennes (School of Engineering), the Joliot Curie sixth form college, EESAB (Rennes School of Art) and the Compagnons du Devoir, Rennes. At the beginning of the month, part of the team will leave for China in order to build the project on site for the first time. Yun and Sheng, two students from Université de Rennes 1, will be part of the trip to Xiamen.
Yun Sun and Sheng Ye, ISTIC students
Launched in 2013, the project currently involves Université de Rennes 1 students from the ESIR (School of Enigneering), IGR-IAE Rennes (Graduate School of Management) and ISTIC (Faculty of Computer Science and Electronics), including Yun Sun and Sheng Ye, two Chinese students.
Specialised in information and communication technology in construction, they are carrying out their work-study placement in the association Team Solar Bretagne. As part of this multidisciplinary team, with their background in ICT engineering for eco-activities (master EEA, ISTIC), they are in charge of home automation and equipment.
A prototype has been set up on the Beaulieu campus. In the laboratory at ISTIC, Yun and Sheng are training to meet the requirements of the competition by simulating the different challenges of the Solar Decathlon. Apart from the construction of the house, the teams will have to carry out 10 tests. Energy efficient, the laboratory is not only a place for research and experimenting, it is also a living space, organised like a house, with a living room, a kitchen and a bathroom.
Both 26 years old, and having lived in Rennes for around four years, Yun and Sheng will also make the French-Chinese dimension of the project easier. For the competition, the Team Solar Bretagne will become the Team Jia+ associating the universities of Xiamen and Shandong in China. Their presence in the team will also help resolve problems of understanding between the two languages and cultures.
During the competition, the team will present the JIA+JIA project. The project consists of renovating an existing building whilst building a new environmentally friendly, bioclimatic house on the same plot, and hence increasing the density of the city whilst avoiding construction on unused land. Built entirely with bio-sourced and local materials, the new house will be lived in by the family who own the land.
The renovated building will be converted into a guest house, allowing the traditional home to be preserved and generating an income for the owners, in the context of China's emerging tourism focused on heritage.
* Members of the Team Solar Bretagne, Albane Gaffajoli (INSA-ENSAB), Anais Lefort (Université de Rennes 2), Jonathan Hardy, Joana Robert, Simon Barre and Violaine Bonis (ENSAB) are going to China this summer along with Yun Sun and Sheng Ye. A compagnon du devoir will be with them to supervise the building site.
