in total energy consumption, building energy consumption accounts for about 35%. Passive buildings play a significant role in relieving the pressure of energy and environment, and have developed rapidly in recent years. In July 19th, the first steel structure assembly type ultra low energy consumption green "passive room" - the construction of the Shandong Jianzhu University, the construction of the Shandong Jianzhu University comprehensive experimental building project completed the top of the structure. The project is the first steel structure assembly super low energy consumption green building in China, with a steel frame structure of about 900 tons. It is expected that the project will be put into operation by the end of this year.
Shandong Jianzhu University teaching and experiment comprehensive building project, six floors on the main floor of the main building, the height of the building is 24 meters, the independent foundation, the steel frame structure, mainly for the laboratory and the research room; the two floors on the floor of the hall classroom, the height of 13.4 meters, the independent foundation and the frame structure, mainly used in the large conference room and the 90 hall classrooms. .
it is known that it originated in the low energy building "passive house" of Germany in the 80s of last century. The best building enclosure structure and indoor environment were constructed with various energy saving technologies to greatly improve the thermal insulation performance and air tightness of the building, so that the buildings need to be reduced to the minimum for heating and cooling. The indoor temperature of the "passive room" is maintained at 18 -24 C all the year. The room has fresh air, no damp and no mold throughout the year. The energy consumption is only 1/10-1/4 of the ordinary energy saving building. If it is converted into domestic standard, the energy saving rate of the building is about 92%. In the northern heating area, it can save 34 million tons of coal in 2050 and will be able to save up to 34 million tons of coal. The annual increment of heating energy consumption is within 1 million tons.
the Shandong Jianzhu University comprehensive experimental building, which is responsible for the construction of the eight bureau and one company, added the "steel structure" to the "assembly" on the basis of the passive room. On the one hand, the "steel structure" itself has the advantages of light weight, high strength, quick construction, convenient pipeline layout and less pollution in the construction environment. On the other hand, the "assembly" construction ensures the quality of the components, the construction operation is convenient and quick, the construction time can be shortened, and the cost of the turnover material, manual and material cost can be effectively reduced. As a result, the innovative combination of "steel structure" and "passive house" and "assembly" can truly realize the low pollution, low cost and low energy consumption of the building. After the completion of the project, it will save nearly 800 thousand yuan of energy consumption and cost.
