On the construction site of the third phase of International Trade City, you may see that walls here are quite different from those in common buildings -- all the walls are made of 240 mm shale porous bricks and covered with 25mm XPS." Building walls with XPS is much different from building common wall sin two procedures:the plastering of XPS and the degree of anti-rupture
. And the construction of out side wall, which is to guarantee warmth in winter and coolness in summer, is much different
from the painting of common walls," said Wu Xiubin, manager of the engineering department of the construction office of the market," the isolation from air by XPS causes a thermal conductivity. Different thermal conductivity causes different energy-saving effect. According to the design requirement, the XPS will have the effect of keeping warmth when the thermal conductivity reaches a certain degree."
According to the requirement of "green, environmental friendly and energy-saving", the construction of the 3rd phase makes good use of solar energy, that is the solar energy PV system .The system is set up in the parking lot of the market to be used as shadow generator structure roof . The project is connected to low-pressure power distribution system of the other
two phases of International Trade Mart through 400w low pressure net system. The system will generate about 1,200,000
kwh each year and the design lifespan is 25 years, which will generate about 30,000,000 kwh. Compared with thermal power generation, the system will save 11750 ton standard coal, lessen 5200 ton emission of carbon dioxide, 230 ton sulfur dioxide and 150 ton dust .
