Building integrated solar energy prospects ready
China is the world's largest energy producer and consumer countries. In China, the total energy consumption in the building energy consumption accounts for 30 percent, while urban and rural areas in China more than 430 billion square meters of existing buildings to save energy building standards only 5%. Even the new building, but also more than 90% is still a high-energy buildings. Therefore, the construction sector has the highest energy saving characteristics economy, while 15% of the hot water energy consumption of the building, it has become a low-carbon solar thermal energy-efficient buildings in a very important part.
"Twelve Five" period, China will actively building a low-carbon demonstration towns, build a green low-carbon industrial system, expected in 2015, China will build 100 new energy city, 200 green energy demonstration counties, 1000 New Energy Demonstration Zone and 10,000 new energy model town. Experts said that the current value of the energy industry in the industry from 300 billion to 500 billion yuan or so, and by 2020, China's investment for the construction of energy-saving projects will reach at least 1.5 trillion yuan, while solar energy, biomass, energy and air energy saving materials in the building will be more extensive.
China is a big country to assume responsibility, announced in 2020, to reduce carbon dioxide emissions by 40% -45% in 2005 based on. This commitment to safety has been known to clean solar energy industry has brought explosive growth in the market space, but also directly spawned the era of high-end applications coming solar, solar energy and building integrated as one of the high-end applications of solar thermal pushed the historical development of the big stage, much attention both inside and outside the industry.
To achieve this commitment, our local governments have to act. As a major agricultural province of Jilin Northeast would be the first action. Jilin Province is rich in solar energy resources, but less application area of solar hot water systems, as of 2010, the province of solar water heating system is only 0.95 percent of the national total area of application. As a representative of low-carbon green city, Jilin municipal government first proposed the new construction, renovation, expansion of 6 floors and six storey residential buildings (including commercial and residential) and hospital wards, school dormitories, hotels, bathing establishments and other hot guzzler public buildings, solar hot water system must be applied. Solar hot water systems and building integrated to achieve synchronized planning, design, construction and simultaneous acceptance synchronous. In addition, for more than seven layers (including Layer 7) residential buildings, other public buildings, to encourage the use of solar hot water system, the city temporarily forced to implement. However, the seven layers above (including Layer 7) new residential solar hot water system usage in 2011 to reach 30% in 2013 to 50% in 2015 to reach 80%.
Up to now, the promotion of Xingtai City, Hebei Province, urban building integrated solar cell 121, 783 single building; the cumulative application of solar water heaters, 17 million square meters of residential building (including the integration of 11.88 million square meters), a penetration rate of 70% the above. New installations in schools, hospitals, hotels and other public buildings concentrated solar collectors over 20,000 square meters; install solar lights, garden lights 2146. From 2008 to 2009, the urban ambient air quality continuously maintain the province's third; 2009 to 2010, the urban ambient air quality meet the national standards for two consecutive years, to achieve a historic breakthrough. And, in the implementation of the city to build solar building work, Xingtai City to take measures to grow the solar enterprises, focusing on supporting a number of key enterprises, through a tender notice published in the news media, to determine the number of merit-based building integrated solar energy demonstration project. Currently, the city installed solar water heaters, 95% are used in Xingtai local products, the solar industry has also been a significant development. In 2010, the city's solar energy industry output value reached 1.35 billion yuan.
The average number of hours of sunshine throughout the year for 1200-2200 hours, Guangxi, solar energy resources to promote greater use of prospects. In this privileged basis, Guangxi CPPCC put forward: To strengthen government guidance, departments linkage, and jointly promote the building integrated solar energy to accelerate the development of Guangxi; improve policies and regulations, and further standardize the market order and design standards; strengthen research and development, marketing and personnel training ; scientific planning, organization and implementation of good demonstration projects, steadily; strengthened standards, supervision and management and technical guidance for capacity-building efforts to explore effective models to promote the formation of building integrated solar energy, promoting renewable energy construction in Guangxi in full swing.
In order to promote the healthy and orderly development of building energy forward, Shanxi Yuncheng City Housing and Urban Construction Bureau of the lead organization Meteorological Bureau and other departments held a Symposium on energy efficiency in buildings, construction and energy industry experts from outside the province, the solar manufacturer to "Solar photothermal building integrated "as the topic to discuss. The meeting discussed include renewable energy applications experience, ground source heat pump technology principle and application performance and application of manganese slag concrete hollow blocks, thermal solar energy development and utilization, performance and application of steel profiles and wall materials of fly ash sintering performance and applications, solar water heating and building integrated design requirements, and building integrated solar design, urban BIPV utilization, performance and screen glass temperature applications.
The rapid development of solar energy and building integration is inseparable from the strong support of government policies, since 2009, more than 20 provinces and Shanghai, Beijing, Shandong, Hunan, Hubei, Hebei, Henan, Zhejiang, Hainan, have developed a "Solar light and heat combined with the construction "plan, and mandatory 12-storey building mandatory installation of solar thermal systems, Beijing, Shandong and other places for the installation of solar hot water systems focus to give financial subsidies. At the same time by the Ministry of Finance and the Ministry of Housing and Urban-Rural Development, co-chaired the "national renewable energy demonstration city" project, has been carried out for two years, included the demonstration of the city, prefecture-level cities receive 50 million yuan -8000 ten thousand yuan central government subsidies, county-level cities receive 18 million yuan of subsidies, local government and then matching the same amount of subsidies, which help promote the integration of solar energy and building real implementation and popularization.
2011 is the national "five" plan the first year, planning not only to carry out the provisions of a pilot geothermal power in Inner Mongolia, Gansu, Qinghai, Xinjiang, Tibet and other appropriate areas, also in 2015 400 million square meters of solar water heaters set of development goals, also plans in rural areas to promote solar water heaters, solar cookers and other thermal devices, to achieve village sunshine bathroom projects, which solar thermal companies, will usher in a new one.
Solar energy and building integrated market development presents an unprecedented explosive. The important task of all solar companies, for solar energy companies in order to cope with the ever-changing market, the only change and policies to meet the trend of the times.
