"Planning" that the "13th Five-Year" period, building energy efficiency and green building development of the overall goal is: to enhance the building energy efficiency standards to enhance the construction of new buildings in the green building a substantial increase in the proportion of building energy-saving transformation in an orderly manner, Renewable energy construction applications gradually expand the scale of rural building energy efficiency to achieve new breakthroughs, so that the overall energy consumption of China's building continued to decline, the building energy consumption structure gradually improved, the construction area of green development level improved significantly.
In recent years, under the guidance of relevant national policies, the pace of green building development in China has been accelerating. Relevant data show that as of September 2016, the national green building logo project totaled 4515, the cumulative construction area of 523.17 million square meters.
But the current green building promotion faces some problems, such as incremental cost constraints. Green building using a good thermal insulation properties of doors and windows materials and other new technologies, new materials, from the construction of the whole life cycle, green building input and output ratio was significantly higher than the traditional building, in the later use of the process, water saving, energy saving , Energy and other aspects of the show a greater advantage, 5-7 years will be able to recover the cost of increase in the construction sector. Because of the increase in the construction of the current period, real estate developers to take into account the cost of the problem, often do not want to increase investment, and even some developers will save the cost of shoddy.
The promulgation of this policy to the green building development put forward new goals, how to promote the development of green building, the National People's Congress Hou Xi Min that public buildings as a green building example.
He suggested that public buildings around the city should be used as a green building to promote the example, the first use of assembly-type construction, and then promote the civil construction and other aspects of the comprehensive promotion of green building. At the same time, strict supervision and supervision of large-scale public buildings, affordable housing projects and government investment in public buildings to implement green building standards, and strictly investigate and deal with green construction within the scope of the implementation of green building standards are not designed and built projects to guide the real estate projects according to green building standards design and construction , To play the project demonstration effect, the construction of a number of high-quality green building.
Assembly of buildings to lift the boom
"Planning" proposed to vigorously develop the assembly of buildings, to speed up the construction of assembly-type construction production base, cultivate design, production, construction integration leading enterprises; improve the assembly-style construction-related policies, standards and technical system. Actively develop steel structure, modern wood structure and other building structure system.
Development of assembly-style construction is the construction industry to promote the supply side of the reform of one of the methods, "three to a comeback", the assembly of architectural commitment to ecological civilization make up short board and iron and steel, cement industry to the task of inventory, assembly is bound to Become an important focus of active fiscal policy.
In recent years, the relevant departments have introduced a series of policies and measures to promote the development of assembly-style buildings, assembly-style building gradually started, but the overall development is slow. Relevant data show that in 2015 the new construction of the new construction area of less than all the new construction area of 3%. At present, the domestic assembly of the construction industry is also facing multiple obstacles, including high cost, policy is not clear, consumer acceptance is low, the model is not clear and so on. The current policy to push or to further reduce the cost of assembly-style buildings, the future can not only integrate upstream and downstream resources, but also reasonable to avoid "cheating" policy risk model will stand out.
In February last year, "the CPC Central Committee and State Council on the further strengthening of urban planning and construction of a number of opinions" put forward, and strive to use 10 years or so, the assembly of the building accounted for 30% of the proportion of new construction. At the end of September, the General Office of the State Council issued the "Guidance on the Development of Fabricated Buildings", which marked the development of assembly-style building which would become an important national policy to promote the transformation and upgrading of the construction industry. Subsequently, the localities have also introduced policies to develop the specific development goals of assembly-style buildings.
The relevant agencies to calculate the target to conduct a conservative estimate of the compound construction growth rate of at least 27%. Estimated by 2020, the industry total revenue 340 billion yuan, gross profit of 80 billion yuan; 2026, the industry total revenue of 1.3 trillion yuan, the total gross profit of 300 billion yuan.
Many industry also made recommendations for the development of assembly-style buildings, which referred to improve the assembly-style building standards need to promote a mature technology system to accelerate the EPC project general contract to play a combination of integrated construction advantages.
Green building materials welcome development opportunities
"Planning" proposed to improve the green building materials evaluation system, there are steps to plan to promote the green building materials evaluation logo work. The establishment of green building materials product quality traceability system, the dynamic release of green building materials catalog, to create a good market environment. To carry out green building materials industrialization demonstration, in the government investment and construction projects in the priority use of green building materials.
At present, the promotion of green building materials, the development of green building, building materials industry to become the only way to upgrade.
But the current development of circular economy, promote the development of green building materials, but also faced with some problems. First, the scope of application is small, low proportion, according to preliminary estimates, the current green building materials accounted for only about 10% of the construction industry materials, industrial scale is only about 350 billion yuan; Second, the standard is not perfect, the existing product standard system, Consider the green elements of the indicators; Third, new building materials products into large, limited corporate funds, lack of development momentum.
Development of green building materials focus on norms, the National People's Congress, China Building Materials International Engineering Group Co., Ltd. Peng Shou, chairman of the strong support for the promotion of green building materials, he proposed the Ministry of Housing and Urban Building green building materials approved standards and accreditation system to carry out energy efficiency audit, the preparation of green building materials catalog Standards, to standard norms as the starting point, the model enterprises to give greater efforts to support the development of green building materials and applications.
At the same time, the establishment of the development of new building materials, circular economy, special funds, green building materials enterprises and green construction projects to subsidize the support of green building materials technology and product demonstration and promotion to support the implementation of major green building projects. Clearly enforce the scope of green building standards, for example, clearly defined the proportion of new buildings in the green building, increase Low-E glass, thin film solar cells, plus energy 5.0 and other green building materials and green building promotion efforts to achieve green building materials in The wider application of society as a whole.
The promulgation of this policy will affect the relevant industries and business development. There are analysts said that thanks to the policy to promote the continued efforts to increase and innovative mode of funding gradually in place, green building materials, renewable energy applications, doors and windows curtain wall, photovoltaic building and energy-saving building materials and other related areas of enterprises in the future Five years to achieve rapid development.
In addition, the "planning" is also actively guide the green construction. Promote green property management model. To construction waste disposal and reuse as the focus, to strengthen the production of recycled building materials technology, technology and equipment research and development and application, to improve the proportion of utilization of construction waste.
