Green building materials gb is brewing
"Our productswhatTime can only through an evaluation can clear across the country?"A building materials company's technical manager've just finished a face of confusion to a green building experts question the speech, but get is ambiguous reply, this is a scene in a seminar in green building.
Between this question answer, reflects the green building materials are: different regions and departments, according to different standard unitv product evaluation system.And in order to meet different needs and market promotion, building materials products, have to accept these a variety of detection.
Once upon a time, the concepts of green building was just born, but as ChinagreenThe standardization of the evaluation standard system and improvement of building green architecture popular in China nowadays, practice in full swing.It's the same when brothers - green building materials and dreams?
Keep up with the trend of the green
A third of the energy consumption of building energy consumption accounts for society, and industrial energy consumption and transportation energy consumption and social three big energy consumption.Research shows that because China is in the process of rapid industrialization and urbanization, with the increasing of the total construction and the improvement of living comfort, the building energy consumption increases sharply.Experts say, if add consume energy in the process of building material production (accounts for about 16.7% of the total energy consumption of the whole society), and construction related to energy consumption will account for 46.7% of the total energy consumption society.
It is in this urgentEnergy savingSituation, the meaning of "green" two words to describe color is no longer exclusive, not just extended for peace and hope.Whether the green building, green building materials, green construction, green decoration, green operation, etc., have been given the nature and connotation of sustainable development.
Along with energy conservation and environmental protection problem is put forward, a "green" concept in the construction industry has gradually become hot spots.Came to China in the 1990 s, the concept of green building, experts have made different interpretations to its, real estate developers also in abundance in the name of "green" publicity and promotion.In order to unify the understanding, on the development of green building in the direction of the rational, the national related departments have issued a series of related measures and specification documents.June 1, 2006, in summarizes in green in our countrybuildingPractice experience and research results, draw lessons from international advanced experience on the basis of the green building evaluation standard set by the began, for the first time for green building labeled the official.In August 2007, "the green building assessment technical conditions" and "green building evaluation identity management method" one after another, China said goodbye to foreign standards evaluation of domestic architecture history, suitable for the situation of China began to build the green building assessment system.
During the period of "11th five-year plan", China's green building development.As of December 31, the labeling program named 742 item of the green building evaluation.
Earlier this year, forwarding the national development and reform commission and the general office of the state councilThe ministryMake action plan for green building, clear "twelfth five-year" period to complete the new green building 1 billion square meters, at the end of 2015, 20% of new buildings in cities and towns to green building standards."At that time, the green building in China will account for more than half of the global green building, will assume the role of the main national energy conservation and emissions reduction."Some industry insiders said.This marked the green building, he thought, strategy has risen to national level.And the rapid development and progress of green architecture in our country, for building materials for energy saving, environmental protection, waterproof, sealing performance are put forward higher request, let the green building materials in the lift.
The foundation of the green building
“beautifulThe realization of the "Chinese dream", it is necessary to promote the urbanization construction of ecological civilization, and green building is the premise of ecological civilization, green building materials is the basis of the development of green building."The representative of the National People's Congress, director of the institute, tongji university, building materials, zhang said. He thought, building beautiful" Chinese dream "based on the building materials industry upgrading and the development of green building materials products.
According to the green building evaluation standard for green building to make definition of green building is in the construction of the whole life cycle, maximize resource conservation, energy conservation, land, water, and materials), to protect the environment and reduce pollution, provide people with healthy, applicable and efficient use of space, and natureharmoniousSymbiosis of architecture.Ministry of industry and puts forward the definition and connotation of green building materials is "in the whole life cycle can reduce the consumption of natural resources and reduce the impact on the ecological environment, the nature is more safe, use more convenient, has the 'energy saving, emission reduction, safety, convenience and renewable characteristics of building materials products".National building materials industrial aluminum-plastic composite materials and sunshade products quality supervision, inspection and test center director Liu Yi believe that the five characteristics of green building materials and green building a green "" four standard is consistent."Due to construction and building materials industry belong to a big industrial chain, and interdependent and inseparable. According to the calculation, construction, every 10000 yuan output value increase consumption of at least 0.350000Yuan building materials products.So for building materials, it is very important in the field of green building."He said.
Liu Yi tells a reporter, the green building green building materials is the consensus in the industry."Green building materials is the foundation of all functional green building goals, for the selection of green building materials to a large extent determines the degree of green building. For example, the problem of green building water-saving, will depend on choose to install the water-saving appliances, safe and durable water and rainwater recycling system of water supply pipe and permeable ground material."
Booming foreign certification
Both new buildings, the existing buildings, and the green building, to achieve the expected greenColor codeAccurate, cannot leave the use and promotion of green building materials.And the history of green building materials in fact was longer than the green building."Since the sixties and seventies of the 20th century, people discovered the" sick building syndrome ", since the world began to live attaches great importance to the beneficial to human body health and safety of green building materials, many countries have established the evaluation system of all kinds of green building materials and certification."Zhang said.
Zhang said that the earliest implementation of the green logo is Germany in the world.Germany in 1978 issued the first environment mark - steel, since this sign for most building materials the pass to the market.In addition, the DanishhealthBuilding material standard, Canadian environmental protection program, the carpet of the marks, Sweden ground material test plan is for related building materials to make a provision quality standards and health standards, become the norm plays an important role in promoting the development of green building materials market.
In the wave of global environmental protection and safeguarding ecological impact, the consumption idea of people pay more attention to health care, physical fitness, prolong life, advocating return to nature.In recent years, many countries in the world have implemented the green plan, with environmental protection and green logo products is becoming more and more get the favour of consumer and the manufacturer.
According to research firm survey, 67% of Dutch, 80% of germans inbuyItems when considering environmental factors;In Europe and the United States, more than half of the degree of green consumers to consider when shopping goods, and more than willing to pay for 30% to 100%.Many of the provisions of the state, any goods without green flag, when import should be restricted quantity and the price.
"Green" or "green"?
In recent years, with the improvement of social development and people's quality of life, the quality and safety become the focus of public attention.Become the largest investment in ordinary people especially housing consumption hot spots, involved in the Chinese people to occupy the link gave special attention to a person's own health, increasing demand for green building materials, health, environmental protection,securityThe green building materials is more and more get the favour of consumer.However, despite the green building materials has become a market to be bestowed favor on newly, had high hopes of its people, but the present situation of green building materials is not satisfactory.
The reporter understands in an interview, for a long time suffer from traditional competition each big businesses, are taking the strategy of "green transition" intentions segmentation this big cake, green building materials in domestic building materials products "green building materials market, with a large number of" copycats.Because of a lack of unified standard authentication, consumer is hard to discern.
Reporter visited Beijing several large building materials market, in ceramic tile, floor, wallpaper, Windows and doors, sanitary ware, furniture, etcsalesArea, everywhere can receive printed with "green", "environmental protection", "energy saving" small advertisement signs, "green", "environmental protection", "energy saving" and other words in the commodity price also can be seen everywhere.Reporters rough statistics, use the "green" and similar words building materials brand, at least accounted for more than 90% of the whole store.
Take a closer look at these building materials products, in addition to the "China well-known trademark", "Chinese environment mark product certification" and other common identity, there are many and "green" smacks of identity, name, color colorful, square has a round shape.As for the identification of the source and authority, the businessman in addition to their confidence, know nothing.The reporterSurf the InternetRetrieval and found that the identity of both government departments issued by unit, there are also building materials testing and authentication institutions, associations and other social groups, and even the news media, joined to the issue of green building materials identification team.And they have the corresponding qualifications, it is difficult to find out.
"These certificate of identity and 99% belong to commercial hype, neither the set threshold for eligible products, also lack of authentication methods and standard system."Liu Yi said.Can certification for green building materials products, he said, the standard should be national standard or standard, but there is no special standard of green building materials in China.
Chinese standards are brewing
"To learn fromforeignExperience can be seen that promotes the development of green building materials, should develop green building materials product certification system.Zhang said. "he said, China's green building materials market chaos, standards lag is an important reason. A lot of new building materials due to the lack of standard uncertainty in to market. It is in view of the significance of green building materials for green building and green building materials to the lag of standard specification, in the action plan for green building green building materials.
Browse action plan for green building the full text, can be found at many points clearly put forward to establish and perfect green building materials standards and evaluation system, such as "national development and reform, urban and rural construction of housing,industrialAnd information technology, quality inspection departments to set up green building materials authentication system, green building materials product catalog, guide the market ";"Study and formulate support the development of green building materials, construction waste resource utilization, building industrialization, foundation ability construction work policy measures such as ";"Perfect the standard system of green building materials, study and formulate evaluation standard, building decoration materials harmful standard norms related to the establishment of comprehensive utilization of construction waste ".
In fact, shortly after the "green action" issued, green building materials standards have begun to start.Commissioned by ministry of China building materials industry planning institute do green building materials industry development policy research topic on January 21, concluding, and ChinaBuilding materialsGroup has also been commissioned inspection certification leading green building materials authentication way, and trial and evaluation standard system directory.It is reported that the ministry and the ministry of industry and brewing methods and standard system of green building materials, green building materials the authority of the definitions and professional certification evaluation system be forthcoming.
It is reported, because there are so many types of building materials, green building materials authentication method will may be a general rule, and green building materials authentication standard is specific to each index of each product."Standard introduced the specific time has not yet been determined, is now in the study of top-level design and measures for the administration."Liu Yi disclosed.
"Green building materials is higher than production costordinaryBuilding materials, and have cost for green product certification.Liu Yi said. "he thinks, green building materials of the national standards or industry standards, once established, the difficulties in the promotion of green building materials is downstream of the green building materials purchasing is recognized, it needs a series of encouraging policies."Should consider whether to producers and consumer subsidies, or in the selection for green building materials building give appropriate points in the assessment of the green building award."Liu Yi said.
