Construction of new energy saving technologies help to promote the economic cycle

In both Building energy efficiency Transformation and new progress in building energy efficiency, while constantly looking forward to building Qingdao new breakthrough energy efficiency, and sights Solar Energy , Ground source, sea water and other renewable Energy The use of energy saving in construction, 13 projects have already been listed as national renewable energy demonstration building applications Project .

Renewable energy, building on the new secret

Yi xingxing in Chengyang district where, if not to the staff, we do not found the secret. Originally, the building was actually the balcony fence solar wall.

To the staff: "The past, many buildings Solar water heaters Most are installed on the roof, not only affects the building's appearance, but also destroyed the roof. Take into account when we design and construction of the combination of solar energy, using the wall and building integrated solar energy. Solar Aluminum color barrier with the same window, reserved area and balcony size photogenic location matched only practical and balanced beauty. Poor winter sunshine and rainy days, they can start the auxiliary heating function, does not affect normal use. "

In promoting new construction and existing building energy efficiency work, Qingdao to turn its attention to building energy-saving renewable energy, to determine the "Eleventh Five-Year" period "to complete the use of renewable energy technologies in building 5 million square meters, to achieve save standard coal 150,000 tons annual. By 2010, the area of renewable energy applications, new construction accounted for 25%% of the proportion of "work objectives.

As solar energy, water, soil and other sources of renewable energy applications in buildings, energy conservation awareness throughout the community have been enhanced. Qingdao renewable energy into the building to the surface from the point of large-scale development stage. In the commercial housing Sell Market, the use of renewable energy has become an important selling point.

Developers Wangen Kui Yi xingxing district, told reporters: "solar energy, Ground Source Heat Pump And other energy-saving technology is now the most promising technology for developers. We are figuring out how to use renewable energy sources. It has also become a selling point is now one of commercial housing sales. "

And Yi xingxing different, Millennium Cell's secret international harmony while others are in the ground. Community adopted a new Heating Cooling technology - ground source heat pump central air conditioning. 80 meters underground year-round constant temperature conditions, the heat exchange through the water cycle can be warm and cold dual-use.

Technical staff told reporters, shallow soil heat from solar energy is inexhaustible and renewable energy use. Emissions and ground source heat pump Air Source Heat Pump Can reduce more than 40% compared with electric heating can be reduced by 70% or more compared to the summer heat to the atmosphere will not aggravate urban "heat island" effect; winter, cold climate from the outside, except air source heat pump does not appear cream and the problem of inadequate heating. Without central heating in urban areas can be greatly reduced and the investment in infrastructure and operation management of manpower, material resources. Various settings can be carried out through the computer, and real-time Monitor The operation of the machine. Because no combustion system set up and running security and stability. Although the focus than the traditional mode of heating plus central air conditioning increased investment per square meter, 100 to 200 dollars, but annual operating costs about 30 yuan per square meter or so (including heating and cooling), and the current focus of Qingdao means not only save energy than heating, but also save a lot of running costs.

Staff said: "The air conditioning within the community to achieve the equivalent of central heating, in winter the indoor temperature at 23 , 24 or so. Costs 4 yuan lower than the municipal charge more, with the occupancy rate of increase in costs will reduction. Each room has a temperature control valve, the owners can adjust their indoor temperature, it is convenient. "
