At present, the building energy consumption to become China's largest energy consumption structure, the construction unit of China's energy consumption is three times the developed countries, China's new buildings completed every year about 20 million square meters have been completed in the near 40 billion square meters of construction, 90 %% For the construction of high energy consumption, electricity consumption in peak period equivalent to 10 full-load output Three Gorges Power Station. Therefore, members of the community are the use of clean energy research and development is full of expectations, the energy-saving equipment R & D institutions are also constantly exploring the use of energy-saving technology to support national policy of the ultimate answer.
Solar industry Huzhiyuchu
10th National People's Congress Standing Committee 30th meeting, voted to adopt a revised draft energy conservation law. Among them, in the amended Article 4 of the energy conservation law clearly provides for "energy conservation" as a basic national policy. At the same time, has been awarded the "Renewable Energy Law" clearly provides that: The state encourages units and individuals to install and use solar water heating systems, heating heating and cooling systems, photovoltaic power generation systems and other facilities, solar energy has become the most Excellent alternative sources of energy. Currently, the country generally has a high energy-consuming construction of the state, the application of solar-thermal, photovoltaic products become rapidly reduce power consumption of a "high-speed road."
According to the text-chul, deputy general manager of Nuorui Te-liang, in China there are about 350 million families, if the use of electric supply, supply of 100 liters per day of hot water of 60 degrees, the annual needs of 664.3 billion of electricity, The country is almost half of the year generating capacity, equivalent to 400 billion yuan. "Renewable energy medium and long-term development planning" in the request, solarthermal use of renewable energy development as the key areas, by the year 2010, the total collector area of solar heater to 150 million square meters, about 20 million tons of alternative standards Coal, to 2020, solar water heaters, the total collector area will reach 300 million square meters, the replacement of about 50 million tons of standard coal, GDP will be over 300 billion yuan.
The government disclosed the information to the development of solar energy industry has brought unprecedented excellent opportunity.
Congenitally deficient construction and integration solution
China's ambitious blueprint for energy planning, this should be solar-thermal products in development in recent years but some Kekebanban, The reason for this lack of corresponding with the national technical standards and regulatory mechanism is not without relevance. According to incomplete statistics, over 4,000 existing solar water heater production and processing enterprises, industries highly decentralized, solar water heaters, the market share of 10 brands was only 20 percent.
Community property has been the staff listed a solar-thermal equipment to install the various drawbacks: the installation mess marginal impact on urban landscape, the destruction of building structure and function, waterproof, mine, precautions, bearing in left security risks; now has the roof A private territory, and there are a lot of hidden dangers late management; scarcity of high-level roof area and can not meet all the needs of tenants; product is not under pressure, a risk of leakage, in high-rise buildings and water supply networks do not match the pressure. These constraints have become solar-thermal industry, the development of a problem.
In this context, the solar-thermal research and development institutions to strengthen gradually in the "building integration" for the development of strength. According to Nuorui Te of the experts, with the construction of solar energy integration, not only simple in construction, to find a suitable location to install, but will be building solar hot water system as the standard system into the field of construction, and achieve The simultaneous building design, construction simultaneously, the coincident acceptance, management of the latter part of sync, making it an integral part of the construction. Use of solar energy in all directions to resolve the construction of hot water, heating, air conditioning and lighting can be used, this will be the future of solar light and heat the best industrial development programme.
Government assistance as key to development
Although the integration of solar energy equipment and construction are maturing, but the solar energy industry has long been accumulated over the years within the shortcomings still to a certain extent, hamper the industry as a whole. Liang Wen-chul said that solarenergy industry lacks the necessary national standards and testing standards, a small number of low-quality products so that the whole industry faces a crisis of confidence. In addition, the marketing model of solar energy products are sold mainly to fragmentation, which is solarwater heaters with the construction of the largest fracture, is considered China's overall energy saving of the biggest shortcomings.
April 19, 2007, Qi Ji, vice minister of Construction issued an approval of the solar energy industry Nuorui Te as the first "national housing industry base," the letter of approval, which means that solar water heaters to be purchased by the owners of the fragmented and self-installation Gradually to the design of the logo, the industrialized production, supply intensive mode of change, solar water heater system as a standard component of the building into residential system. This not only represents the state of Nuorui Te integration of solar energy technology with the construction of the affirmative, at the same time means that more "over the years is expected to defuse the biggest solar water heater industry marketing bottlenecks."
At present, solar water heaters for domestic construction has been gradually recognized by the system, Shanghai, Shandong, Zhejiang, Shenzhen and other places set up solar energy and building standards Atlas, which is also on the development of solar energy around the formation of a strong rally. In a batch of enterprises to promote social responsibility, integration of solar energy and construction has made initial success.
