Solar Energy Building the future "to energy conservation but also capacity" – solar energy – solar power industry

Appearance is a Chinese bamboo, the interior wall and the refrigerator is decorated with thermal insulation coating material equivalent, the whole house with solar energy as the only Energy Meet the family of heat and electricity needs of everyday life … … this is named "solar bamboo," the building, is a student of Tongji University last six months the team time-consuming design and built. It will, as entries, went to Madrid, Spain, in June this year at the 2010 Solar Decathlon Europe competition court appearance. Yesterday, the "solar bamboo," the expedition departure ceremony was held in Tongji University campus. Tongji knowledgeable people know, hut it is a magic lies not only in energy-saving buildings, it is a capacity building.

Aspect: energy production, a party Reporter learned that solar decathlon competition has so far held two. In June of this year's competition will be held Spain, the first time the "invitation" to the Chinese University running. This, together with Tongji University, "eat crab" Tianjin University, another college or university.

Teachers, according to team leader, green buildings and Tongji University, New Energy Research Center Deputy Director Professor Tan Hongwei introduction, the biggest highlight of the building, will the Chinese classical architectural elements and solar photovoltaic technology skillfully together. Install solar PV panels, the roof suddenly highlights the advantages of the design: it makes it possible to maximize the efficiency of PV panels generate electricity, but also conducive to air cooling, but also natural drainage.

Solar bamboo also focused on a number of passive and active building energy saving technology: bamboo as eco-facade of the main construction materials; outside the window is used in residential areas with the highest standards of thermal insulation layer hollow glass vacuum + ; Apply interior wall of the covert material can ease the temperature changes; in PV module back to set the cooling and heat recovery units, and cooling air duct, both heat-recovery, but also to ensure efficient power … … addition, the cabin can realize intelligent control of information, residential energy, environmental information can be visually displayed to the occupants of view, and presented in 3G handsets.

Tan Hong Wei told reporters, bamboo solar power generation 9 kwh per hour, while the house used in a variety of energy-saving equipment, the daily power consumption will be controlled within 2-3 kWh per hour. Bamboo can generate excess heat supply of public infrastructure, it represents the future direction of building the "capacity building."

Solar Decathlon competition, the most competition system "Aspect" is that competition for residential solar power systems produce energy, 3-6, were participating students to meet normal living in it, and to invite other players to the residence a party, to provide 8 to enjoy the dinner.

Weaknesses: hard to promote the cost is too high

Bamboo solar energy compared to traditional building more than 80%, but as the entries, it is still able to escape all the new technology products, "weakness"?? Cost is too high, difficult to promote.

According to reports, the construction of such a bamboo, the cost of at least 400 million yuan, while the foreign cost is as high as 100 million euros.

Learned, Tongji University, the reason can become a real house, from design drawings to housing, the key is to get sponsors to support domestic manufacturers more than a decade. "Any new products, new technologies should be promoted, first to support policies introduced by the government." Professor Tan Hongwei said that despite the high cost of solar buildings, but Japan, Canada and other countries have started to promote small-scale. Once large-scale production, the construction cost can be greatly decreased.

Some experts jokingly, Tongji this can be said to spend much because the overall removal of solar bamboo and sea freight shipped to Spain more than 1 million yuan. At this point, Vice President of Tongji University, commander of Towns and residential projects, said solar energy, sea freight was so high that he actually "painful", but the competition is significant. "Tongji not only to show the world we are building research and development in solar energy levels, will fight for matchmaking, lobby competition will be the next chairman of the main stadium on China to allow more people to experience and enjoy the solar building close to the live band to the surprise.
