The "Twelfth Five-Year Plan" of the Ministry of Housing and Urban-Rural Development
During the "Eleventh Five-Year Plan" period, my country's national economy maintained steady and rapid development, and the scale of fixed asset investment continued to expand, providing a good market environment for the development of the construction industry.
"Twelfth Five-Year" building energy efficiency targets are determined
Recently, my country’s "Twelfth Five-Year Plan for the Development of the Construction Industry" (hereinafter referred to as the "Plan") announced that the requirements for energy conservation and consumption reduction in the construction industry have become a highlight throughout the entire plan, and strive to formulate clear development goals and adopt detailed Effective measures to promote energy conservation and emission reduction in my country's construction industry.
"The Twelfth Five-Year Plan for the Development of the Construction Industry" dual impetus to promote the sustainable development of the construction industry
The "Twelfth Five-Year Plan" period is a crucial period for building a well-off society in an all-round way. During the "Eleventh Five-Year Plan" period just past, my country's construction industry has made great achievements. Driven by investment in fixed assets and the continuous acceleration of the process of urbanization, during the "Eleventh Five-Year Plan" period, the added value of my country's construction industry increased by an average of 20.6%, exceeding the development goals of the "Eleventh Five-Year Plan". In 2010, the total output value of the construction industry reached 9.5206 billion yuan, and its share of GDP increased from 5.53% in 2005 to 6.6%. The construction industry employs more than 40 million people in society, and it has become an important industry that attracts a large number of rural surplus laborers and stimulates the development of the national economy. Behind the rapid development of output value is the backward development model, the slow level of informatization development, the excessive consumption of resources, the lack of patents and technologies, and the shortage of high-quality talents. Coupled with intensified competition in the construction market at home and abroad, my country’s construction industry is still There are some problems that cannot be ignored. A few days ago, the Ministry of Housing and Urban-Rural Development issued the "Twelfth Five-Year Plan for the Development of the Construction Industry", which proposed to ensure the quality and safety of projects as the core, accelerate the transformation of the construction industry development mode and adjust the industrial structure as the main line, and focus on building energy conservation and emission reduction. As the focus, continue to deepen the reform of the construction industry system and mechanism as the driving force, focus on the improvement of laws and regulations and standard systems, and support technological progress and innovation, increase government supervision, strengthen industry development guidance, and promote the sustainable development of the construction industry Guiding ideology. Energy saving and emission reduction are the key After the rapid development of the "Eleventh Five-Year Plan", the construction industry has ushered in new opportunities and challenges in the "Twelfth Five-Year Plan". Energy conservation and emission reduction, industrial upgrading, and technological innovation are still the focus of the development of the construction industry during the 12th Five-Year Plan. According to relevant data, my country has to build 2 billion square meters of new buildings every year, which is equivalent to about 40% of all new buildings in the world every year. It is the country with the largest amount of new buildings every year in the world. At the end of the "Eleventh Five-Year Plan", the energy consumption of my country's construction industry accounted for about 30% of the country's total energy consumption, and it has become a major energy consumer. With the rapid development of the construction industry, the problem of high energy consumption in the industry has become increasingly prominent. my country's existing residential area exceeds 40 billion square meters, most of which are high-energy-consumption residential buildings, and their energy consumption is three times that of developed countries. Therefore, the sustainable development of energy conservation and emission reduction in the construction industry is the key. Building energy conservation is a key area of energy conservation and emission reduction in my country. During the "Eleventh Five-Year Plan" period, under the guidance of the Ministry of Housing and Urban-Rural Development, the China Construction Industry Association has actively promoted energy conservation, emission reduction and technological progress in the construction industry, and formulated the "National Construction Industry Green Construction Demonstration Project Management Measures (Trial)" and "Main Indicators for Acceptance and Evaluation of National Construction Industry Green Construction Demonstration Projects", and the creation of "Green Construction Demonstration Projects" activities have been launched. my country's construction industry has achieved remarkable results in energy conservation, emission reduction and scientific and technological progress. Building energy conservation and green construction have made considerable progress. By the end of 2009, the total area of green buildings reached more than 20 million square meters. The implementation rate of the national energy-saving standards for new urban buildings reached 99% in the design phase and 90% in the construction phase. The heating metering of existing residential buildings and the energy-saving renovation of 100 million square meters were completed. It has formed the capacity to save 750,000 tons of standard coal and reduce carbon dioxide emissions by 2 million tons per year. At present, green economy and low-carbon technologies are emerging globally. Many developed countries have invested huge sums of money to support the research and development of energy conservation, environmental protection, new energy and low-carbon technologies. The development of energy conservation, environmental protection and new energy industries has become a new field of international competition. For this reason, the "Twelfth Five-Year Plan" puts forward the basic principles of insisting on combining energy conservation and emission reduction with technological innovation. Develop green buildings, strengthen energy conservation and emission reduction in the whole process of engineering construction, and realize low-consumption, environmental protection and high-efficiency production; vigorously promote technological innovation, management innovation, and green construction in the construction industry, develop modern industrial production methods, and make energy conservation and emission reduction a construction industry Develop new growth points. At the same time, the plan requires all relevant departments to strictly fulfill their energy-saving and emission-reduction responsibilities, focus on the supervision and inspection of energy-saving standards in the design and construction phases; establish an incentive mechanism that is conducive to the low-carbon development of the construction industry, and encourage advanced and mature energy-saving reductions. Emission technology, technology, etc.; reduce the use of building materials with large carbon emissions, and control the negative impact of noise and water pollution in the construction process on the environment. Carry out pilot projects of energy-saving and emission-reduction technology integration projects such as green construction demonstration projects, and comprehensively establish a green sign system for housing construction. Technological innovation is the means The development of energy conservation and emission reduction is inseparable from the adjustment of industrial structure and technological innovation. With the in-depth development of industrialization, informatization, urbanization, marketization, and internationalization in China, the continued deepening of economic globalization has brought more opportunities for the construction industry to "go global". The "Going Global" strategy is a common strategy for construction companies during the "Eleventh Five-Year Plan" period and has also achieved great results. During the "Eleventh Five-Year Plan" period, construction companies actively explored the international market, and foreign contracted projects have achieved rapid growth, with an average annual growth rate of more than 30%. my country's foreign contracting projects started from the Asian and African markets and have now expanded to more than 180 countries and regions on five continents, and the market structure has been further optimized. Facing the ever-increasing amount of domestic and foreign construction projects and the requirements of sustainable development-oriented www.gesep.com energy-saving and environmentally-friendly society for construction projects, it is urgent to combine modern information technology with new technologies, new processes, and new materials to promote Design, construction, production processes and methods, enterprise management models, and innovations in collaborative management between enterprises, thereby enhancing the core competitiveness of my country's construction industry. The "Twelfth Five-Year Plan" proposes that in the next five years, on the one hand, it is necessary to guide qualified large-scale enterprises to develop from a single business area to multiple business areas, and continuously improve their core competitiveness; constantly improve the market access system and standardize The main market behavior of all parties promotes the development of small and medium-sized construction enterprises in the direction of specialization, specialization and precision; constantly innovate service brands, improve service quality, and vigorously develop professional engineering consulting services. On the other hand, improve the construction industry technology policy system, continue to increase the promotion of "10 new technologies in the construction industry" and other advanced applicable technologies; accelerate the establishment of an industry technology innovation system that is enterprise-themed, market-oriented, and combines industry, education and research , To promote the technological update and innovation of the construction industry; to actively promote the industrialization of construction and improve the level of industry informatization, and organize research in key areas and key technologies. The plan also proposes goals to be achieved at the end of the "Twelfth Five-Year Plan" period in six aspects: industrial scale, talent team building, technological progress, building energy conservation, building market supervision, and quality and safety supervision: The added value of the industry has increased by more than 15% on average, and the construction industry’s status as a pillar industry in the national economy will be consolidated; the construction of a talent team will be strengthened, and a group of professional and technical personnel, compound talents and high-skilled personnel will be cultivated; and investment in science and technology will be increased in high-rise buildings, Underground engineering, high-speed railways, roads, hydropower, nuclear power, etc. https://WWW.GESEP.COM The survey and design, construction technology, and standard specifications in the field of engineering construction have reached the international advanced level; establish a green building, green construction evaluation system, and The energy consumption per unit value added during the product construction process is reduced by 10%, and the construction of new projects meets the requirements of the national building energy efficiency standards; further improve the construction market supervision system and standardize the market order; in addition, further improve the quality and safety supervision regulations and resolutely curb major buildings And the occurrence of production accidents, by 2015, the death toll from production safety accidents in housing construction and municipal engineering will drop by more than 11% compared with 2010.

By 2020, my country's investment in building energy efficiency will exceed 1.5 trillion yuan
Qiu Baoxing said that China is a big country in the construction industry, with a total construction volume of approximately 2 billion square meters each year, which is close to half of the global total construction volume. According to reports, the implementation of energy-saving standards in new buildings in my country has achieved remarkable results. As of October 2007, 97% of new urban buildings across the country implemented energy-saving standards during the design phase, and 71% of them implemented energy-saving standards during the construction phase, an increase of 1% and 17% respectively over 2006. Based on this estimate, the energy-saving buildings built from January to October 2007 can form an energy-saving capacity of 5 million tons of standard coal.

Insulation materials become accomplices again, Shenyang's tallest building is lit by fireworks
Our newspaper reported that just after midnight on February 3, the Dynasty Wanxin Building, known as the tallest building in Shenyang, caused a fire due to the setting off of fireworks. The Shenyang police claimed that the surface of Building B, Building A and some rooms of the building were overfire, but no casualties were caused. The water gun cannot reach the burning floor "It's too miserable!" It was about 0:50 on the 3rd when the reporter rushed to the scene of the fire and heard what some onlookers were saying near the building. The reporter stood at a distance of one to two hundred meters from the building and looked up at the building. The 150-meter-high apartment building on the west and south sides of the building B had the largest fire. The flames and thick smoke rose from the wall, and the fire quickly spread to the interior of the building. Flames spurted out from the windows one after another, the fire was burning with bursts of noise, and some burning materials continued to fall. Although the two elevated water guns lifted up to several tens of meters, they were still helpless against the high fire. After burning for more than an hour, the fire spread to the main building of Block A, which is more than 200 meters high, and the main building soon caught fire. "Are there any casualties?" "I haven't found it yet. More than 50 people in the building have been evacuated. Now the main reason is that the building is too high. Our water guns are not high enough, and the water and foam can't get up!" The members loudly reported to the leaders of the provinces and cities and the leaders of the Public Security Department at the scene. Surrounding residents were evacuated With the development of the fire, the person in charge on the scene decided to further evacuate the nearby five-star hotels and residential houses. The focus of fire rescue is to avoid casualties. At 11:30 on the 3rd, the reporter saw that most of the exterior of Block A was overfire, but there was basically no open flame. The upper part of the apartment building of Block B was still covered by billowing smoke, and there were still flames burning in some rooms. Last night, the Shenyang police issued a report stating that the fire was caused by the setting off of fireworks and firecrackers igniting the surface decoration materials of the building, causing the surface of Building B, Building A and some rooms to burn. The fire was extinguished at 9 o'clock on February 3, causing no casualties. Comprehensive Xinhua News Agency and other media reports ■ Witness More than 100 meters long fireworks are placed outside the hotel The Shenyang Aviation City community is separated from the Huangchao Wanxin Building by only one wall. At about 11:40 on New Year's Eve, Mr. Sun saw from the opposite side of the hotel that on the road outside the hotel's main entrance, there were four rows of firework bombs on the three-lane road from north to south, each of which was about 100 meters long. "It's so beautiful, just like the fireworks at the opening ceremony of the Olympic Games." Many of the aviation city owners who were onlookers said that during the Spring Festival last year, a large-scale fireworks display was displayed in front of the newly opened Wanxin Hotel, but the scale was not this time. Big. The staff in the Duty Office of the River Garden District, just across the road from Wanxin Hotel, said that for this fireworks display, the three lanes from north to south in front of the hotel were temporarily closed. After setting off for half an hour, some onlookers suddenly said, "Why is there smoke over there?" Mr. Sun said that the smoking place is probably on the 6th floor, where there is an LED display mounted on the outer wall of the building. Mr. Sun said that within a few minutes, a flame appeared in the smoking location, and some people in the crowd began to exclaim, "It's on fire!" Then someone called the police. After receiving the police, the Public Security Department of Liaoning Province and the Public Security Bureau of Shenyang City quickly mobilized police to the scene. Liaoning Provincial Party Secretary Wang Min, Governor Chen Zhenggao, Shenyang Municipal Party Committee Secretary Zeng Wei, Mayor Chen Haibo and many other provincial and municipal leaders also rushed to the scene to direct rescue. Several witnesses said that about 5 minutes after the alarm, public security and firefighters arrived at the scene, but the original fire has turned into a raging fire. In the apartment building of Block B that caught fire, almost every window spouted out the tongue of fire. The burning material on the outer wall of the building continued to fall with the wind, and the west and south sides of Block A were also ignited. Our reporter Jia Peng ■ Influence Hundreds of residents stay overnight in hotels After the incident, the halls of the Sheraton Hotel and two other hotels near the scene were full of people. Some people claimed that they were all owners of the Aviation City community. After the fire broke out, the community property staff knocked on the door and asked them to leave as soon as possible. , Many people did not bring other items except the home key. "The fire is extinguished, we can go back." Ms. Ji, 70, said that she did not expect to spend the first day of the new year in a hotel. At the time of the incident, she and her son's family of three had just finished eating dumplings and were asked to evacuate. Later, the TV ran out without turning off. Another old man in a wheelchair said that he was carried downstairs by his son. He thought he would be able to go home after a while. He did not expect to wait so long. He said that the distance between his balcony window and the burning building was less than 20 meters. , I don’t know if it will burn to my own home, "I’m tired from sitting, and I don’t want to sleep." According to the staff of Aviation City, about 400 people were evacuated because they were worried that the building would be seriously damaged after overfire, which would threaten some residential buildings in the community. At 6 o'clock in the morning yesterday, these owners were allowed to go home after the fire was brought under control. Our reporter Jia Peng ■ Reflection Firecrackers on holidays bring safety hazards In recent years, the firing of firecrackers has undergone a repeated ban and lifting of the ban. However, while firecrackers bring people a festive atmosphere, they not only cause serious air pollution, but also pose a serious threat to fire safety. The preventive measures of the Dynasty Wanxin Building are obviously insufficient. According to an eyewitness at the fire scene, near midnight on New Year’s Eve, I do not know whether it was the apartment owners, hotel occupants, or the building manager. A large number of firecrackers were placed under the building. The length of the building was one or two hundred meters, and even occupied. Part of the road. "These firecrackers are expensive ‘big firepower’, with loud explosions and a wide range of explosions. Because they are too close to the building, they can easily ignite flammable materials outside the building.” External wall insulation materials contribute to the fire The outer wall of the Dynasty Wanxin Building is covered with an insulation board. A person from a construction company in Shenyang said: “At present, flammable insulation boards are commonly used in local buildings, and the outside of the building is like a layer of gunpowder. Once a fire occurs, it will quickly burn out, which is very dangerous.” Not long ago, a responsible comrade of the Fire Department of the Ministry of Public Security was interviewed by a reporter from Xinhua News Agency and talked about the “11·15” fire in Shanghai. He said that there were a large number of flammable polyurethane foam insulation materials on the exterior of the building on fire, which was an important cause of the fire. One. Fire truck, Nanna, high-floor fire The reporter saw at the scene that although the provincial and municipal public security fire departments quickly mobilized a large number of fire trucks, hundreds of fire trucks were gathered near the fire site, most of which were of no use. Several ladder trucks were raised to the highest height and could only be put in the water gun. The water hit sixty or seventy meters high, while the apartment building in Block B was 150 meters high. There was nothing to do with the upper floors. The fire in the apartment building in Block B eventually spread to the main building in Block A over 200 meters high. In recent years, more and more super-high buildings have been built in Shenyang. There are dozens of super high-rise buildings and a number of them are under construction. Buildings are built higher and higher, but fire fighting in tall buildings is a worldwide problem. According to relevant experts from the Shenyang Fire Department, high-rise building fires are generally difficult to fight with external forces.

Buyers of real estate that do not save energy can claim compensation
"Guangdong Province Civil Building Energy Saving Regulations" will be implemented on July 1 The reporter learned yesterday that Guangdong’s first provincial-level local regulations on building energy efficiency, the “Regulations on Civil Building Energy Efficiency of Guangdong Province” (hereinafter referred to as the “Regulations”) will be officially implemented on July 1. The "Regulations" clarify that developers must disclose the energy-saving information of buildings when they sell buildings. If the building does not meet the energy design indicators, buyers can request repairs or even claim losses.
Whitewash the roof to cool the earth
Andalusia, the largest autonomous region in southern Spain, is famous for its white mountain city. All the buildings in the mountain city are painted white because the white color can reflect the heat of sunlight, thus keeping the interior cool. Can this Mediterranean "cooling secret" be used to solve the problem of global warming? More and more scientists are confident that this idea has certain feasibility. The reason is that the city roofs and roads are covered with light-colored paint or materials to reflect the sun's rays without absorbing heat. A new study by researchers at Lawrence Berkeley National Laboratory in California, USA, shows that "light reflection" on roofs and roads can offset a large amount of greenhouse gases. In addition to reducing air-conditioning power consumption, this move can also buy time and wait for cleaner energy. In this regard, the US "Los Angeles Times" reported that: Globally, the roof area accounts for 25% of the total area of most cities; the road area accounts for about 35%. If 100 major cities replace the roofs and road surfaces with reflective materials, it will be able to offset 44 billion tons of greenhouse gases. These greenhouse gases trap heat in the atmosphere and change the climate. At present, global climate negotiators are focusing on issues such as "limiting fast-growing greenhouse gas emissions". If the "cool roofs and roads" plan is implemented, countries do not even need to do too much on reducing industrial pollution. . Lawrence Berkeley National Laboratory researcher Dr. Hashim Akbari, has been engaged in the research of "urban heat island effect" (a phenomenon where the temperature in urban areas is significantly higher than that in suburbs) for many years. According to his calculations, based on the current price of "carbon trading", the value of "cool roofs and roads" amounts to 1.1 trillion US dollars. He hopes to call on the United Nations to take relevant measures. But, like most grand plans, the "Cool Roofs and Roads" plan will always face various difficulties in its implementation. In many places, regional regional environmental protection regulations have strict regulations on architectural styles including roof colors. Since 2005, the "Interim Provisions for Building Standards" implemented by California, the United States, requires the roofs of commercial buildings to be painted white. Currently, this requirement has been extended to the roofs of other buildings. Although California's environmental protection boom is high, it has its limitations-California cannot turn all "black roads" into "white roads" overnight. If a city as large as Los Angeles can “completely whiten” the roof and pavement, then the plan proposed by former US Vice President Al Gore to “transform the United States into a country that fully utilizes renewable energy within 10 years” will surely save money, More feasible.

Can be used to verify the authenticity of the reflective heat insulating coatings
Will reflect heat insulation coatings products introduced before the European and American companies are vacuum micro beads as filler, with low thermal conductivity as heat insulation means to produce heat insulation coating products, this is a low reflectivity of the ordinary white wall paint, he advertised as the coating layer is very small, can block the conduction of heat, then they will not mention the solar reflectance, so they also claim that their products can use. In fact, the heat insulation paint really do?
