Recently, "zero energy consumption" residential building, designed and hand-built by 20 professors and 50 students at Tsinghua University, was set up and is expected to be completed in April this year.
The "zero-energy" residential is located in an open space on the east side of Tsinghua Natatorium. The steel structure of the house has been completed. According to the professors who participated in the construction, this "zero-energy" residence is called "O-house ", Covers an area of more than 250 square meters, of which housing construction area of about 80 square meters, which is Tsinghua University to participate in the International Solar Decathlon works.
The contest is a solar building competition organized by global universities. With the help of the technology and creativity of the world's top R & D teams, the competition will create a comfortable and liveable solar energy living environment. The competition required the participating team to actually build a home with solar energy as the only source of energy for running and living, and all materials, equipment and funds were collected as a donation, with only 10 days to complete the construction of the building during the final race.
It is reported that the contest for the first time this year settled in China, 13 countries in 35 teams composed of 22 teams reached the finals, nearly a thousand students will be in Shanxi Datong showdown.
Most cow site
Dozens of black bars have been sketched out the framework of the house, the house is like being built "giant blocks", a net height of about 2.5 meters, horizontal and vertical bars are all fixed by screws, the bottom is provided with 40 small feet, adjustable height. The house is a modular structure, with removable materials such as steel, wood, waterproofing membrane, and cement, and every partition in the house is detached and reassembled.
"During the competition, we had only 10 days to rebuild the house, so all the building materials were standardized design, after construction we have to practice a disassembly and preparation for the July competition." Key members of the team, Tsinghua University School of Building doctoral Dong Lei said introduction.
As the energy consumption of this house is all from the solar energy, water resources will be recycled, low energy consumption, environmental protection, advanced design concepts and strict requirements, "zero-energy" construction site was netizens dubbed "the most cow site" .
Steel structure to help zero-energy residential
Just as car ownership and computerization are the same, steel structure construction is undergoing a transformation from public housing to civil construction. This is considered by the Chinese as a high-grade, high investment type of construction will be for the development of the construction industry to bring what kind of market opportunities and innovative products, the Tsinghua University's bold attempt to greatly promote the industrialization of steel structure housing process .
Steel structure with high strength, light weight, good seismic performance (good ductility), plastic deformation ability, construction speed, high degree of industrialization, environmental protection and so on. Of course, the end of steel-framed residential buildings can produce more eco-friendly and high-quality just-concluded homes. The use of scientific and rational design and construction technology, the use of wind energy, solar energy and other natural clean energy and steel structure of the perfect combination of residential construction technology. For people to build green and healthy residential buildings to meet the needs of people's lives.
Over the past few days, most areas in the northern part of the country have been shrouded in haze and haze, and building an eco-friendly China has become an urgent task. It is believed that in the future development of the construction industry, there will be a great deal of steel-framed construction.
