Energy saving solar water heaters have been repeatedly blocked why – water heate
Inexhaustible solar energy is the country to encourage the use of clean energy. However, Shijiazhuang, Hebei's recent interview to find the number of new residential property companies in the overall aesthetic impact of housing, damaged the roof of the ground water level does not allow owners to install solar water heaters. Experts believe that the adoption of legislation to ensure energy-saving technologies and building integration of solar energy, will be the trend.
Xing District in Shijiazhuang City of God, the owner complained to reporters Liu forests: use of electric water heater, a bath every time before going to warm for a long time, and the power consumption is very large, a month doing we have to spend hundreds of family element. He wanted to safety a solar water heater, so hot water will not have to spend the money power. But it was the property the company halted the grounds that "the owners have been provided in the Convention, not to install solar water heaters in the roof."
Same situation also occurs in Shijiazhuang International City district, according to the plot owners Liu Sanhuan say they live in top floor, easier to install solar water heaters can not allow property owners to install the company. She believes that now the whole community in promoting environmental protection energy conservation, if the fear of residents to install water heaters will have their own problems, why the development of real estate developers are not unified when it installed?
Reporter visited Shijiazhuang Tianshan? Waterside flowers, Xintiandi, Kinmen and Matsu and other real estate new area and found that these new communities are not allowed to install solar water heaters. Reporter from Shijiazhuang City Bureau of Science and Technology Department understand that the city has no unified installation of solar equipment units. Not only is the Shijiazhuang city, according to media reports, Hainan Province, Haikou, Fuzhou, Fujian Province, Henan Province have happened Ye County District residents have been ordered to install a solar water heater blasting things.
The interview, the International City residential property company official told reporters about the installation of solar water heaters, two drawbacks: First, as owners to purchase a water heater brands, different specifications, would undermine the appearance of the building face; Second, floor structure will result in hazards, likely to cause leakage problems.
He said that as the design district in the development of solar water heater is not considered, if the residents are now private installation of solar, then the roof's load-bearing capacity will be affected; also may damage the waterproof layer. And because real estate does not allow the water pipes through the roof, the owner if the installation of solar energy, up and down the water pipe from the ventilation tube generally, this will certainly affect the ventilation. Meanwhile, residents on their own non-standard installation, but also create safety hazards such as wind and lightning.
Reporter then visited the liberal arts district, Shijiazhuang, Ming Sheng residential real estate sales offices and some new, when asked "whether the installation of solar water heater", the sales staff have said: "In the housing plans did not take into account use of solar energy. "One of the sales staff also told reporters:" At present, project approval is not mandatory when the government must install solar energy. As developers complete the installation of solar equipment will not only make money, but also to pay a certain cost, can Nature is not installed not installed. "
Encourage the integration of solar energy technology and construction
Reporter interviews some residential areas in Shijiazhuang City, found that the attitude with developers in stark contrast to the residents to install solar water heaters for a very strong desire. Residents generally felt that: Shijiazhuang sunny days per year more than half of that in this climate, the use of solar water heaters under the convenient and affordable. That in the end there is no perfect way: both use solar energy, residential landscape without damage, safety hazard it?
Hebei Province, Deputy Director of Department of Construction Technology Yejin Cheng said in an interview, one-time installation of solar equipment, operating costs low, is conducive to promoting universal security, saving, environment-friendly energy equipment; but the residents unauthorized installation of solar energy does bring some risks. He believes that the integration of solar technology and architecture is the main direction for future promotion.
Industry analysts pointed out that China has built nearly 400 billion square meters of construction, 90% of high-energy construction, and construction of new buildings in the proportion of high energy consumption is still high, it became important in building energy efficiency the weight. Along with saving energy and construction of large area, high-rise residential building in the town building more and more widespread, how to promote solar energy in high-rise building in the application, should become a key concern.
