At the 2011 European Sustainable Energy Week that ended recently, Tongji University student works "Solar Solar House" and Tianjin University's "Sunflower" solar house shared with college students' works from the United States, Spain and other countries. The European Commission issued the European Commission in 2011. Sustainable Energy Award.
It is reported that "Solar Solar House" is a work of Tongji students participating in the first European "Solar Decathlon Competition" held in Madrid, Spain in June 2010.
Tongji Solar Bamboo House is a green ecological hut with a construction area of ​​74 square meters. The main building material of the hut is bamboo. The pattern is one bedroom and one hall. The Chinese classical building anti-woo roof structural elements are adopted. The curved roof can not only maximize the photovoltaic panel power generation efficiency, but also facilitate ventilation and heat dissipation. Bamboo House also integrates a number of building energy-saving technologies and energy-saving systems to efficiently use and manage the light energy, electricity, and heat required for daily life. Ecological bamboo is used for exterior walls and interior surfaces of bamboo houses; the wall is equipped with a new type of high-performance vacuum insulation board; the outer window is made of glass material with the highest insulation level, and the heat insulation performance is 4 times better than that of ordinary windows; The new materials used in the sandwich can utilize the temperature difference between day and night to adjust the room temperature. The roof is covered with solar photovoltaic modules. The back of the module is also equipped with heat dissipation or heat recovery devices to recover heat and ensure power generation efficiency.
According to the award-winning introduction materials provided by the European Commission, the use of bamboo as a building material has the advantages of convenient material acquisition, low cost, and rich cultural heritage.
