Analysis on the 13th Five-year Development Plan and Market Hotspots of Green Buildings
policies and regulations
Recently, the Ministry of Housing and Urban-Rural Development issued the "13th Five-Year Plan for Building Energy Efficiency and Green Building Development", aiming to build an energy-efficient, low-carbon, green-eco, intensive and efficient building energy system, and promote the supply-side structure of housing and urban-rural construction. reform.
1. By 2020, the energy efficiency level of new buildings in urban areas will increase by 20% compared with 2015. The building energy efficiency standards of key areas such as some areas and building doors and windows will reach or approach the international advanced level.
2. The proportion of green building area in urban new buildings exceeds 50%, and the proportion of green building materials application exceeds 40%.
3. The energy-saving renovation area of ??existing residential buildings will be more than 500 million square meters, and the energy-saving renovation of public buildings will be 100 million square meters. The proportion of energy-saving buildings in existing urban residential buildings will exceed 60%.
4. The proportion of urban renewable energy alternative civil construction conventional energy consumption exceeds 6%.
5. Breakthroughs in energy-saving of rural buildings in economically developed areas and key development areas, and the proportion of energy-saving measures adopted exceeded 10%.
Green buildings have become the focus of the two sessions in 2017, and many NPC representatives have made suggestions for their development. At the same time, various places have introduced green building development goals, and green buildings are welcoming new development climax.
Green building overall development goals are clear
According to the "Planning", during the "13th Five-Year Plan" period, the overall goal of building energy conservation and green building development is to accelerate the improvement of building energy-saving standards, and the proportion of green building promotion in urban new buildings will be greatly improved, and the existing building energy-saving renovation will be promoted in an orderly manner. The scale of application of renewable energy buildings has gradually expanded, and new breakthroughs have been made in energy conservation in rural buildings. The overall energy intensity of buildings in China has continued to decline, the structure of building energy consumption has gradually improved, and the level of green development in the construction sector has 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 identification project has reached a total of 4515, with a cumulative construction area of ??52.317 million square meters.
However, the current green building promotion faces some difficulties, such as the restriction of incremental costs. Green buildings use new technologies and materials such as door and window materials with good thermal insulation properties. From the perspective of the whole life cycle of buildings, the ratio of input and output of green buildings is significantly higher than that of traditional buildings. In the later use, water conservation and energy saving Energy conservation and other aspects have shown great advantages, and 5-7 years can recover the increased costs in the construction process. Because of the increase in investment in the construction phase, real estate developers are often reluctant to increase investment in consideration of cost, and even some developers will replenish it in order to save costs.
The promulgation of this policy has set new goals for the development of green buildings. For how to promote the development of green buildings, Hou Nian, a representative of the National People's Congress, believes that public buildings are the model for green buildings.
He suggested that public buildings in various places should be used as a model for green building promotion, and they should take the lead in adopting assembly-based construction, which in turn will promote the comprehensive promotion of green buildings in civil buildings. At the same time, strict supervision of large public buildings, affordable housing projects and government-invested public buildings to implement green building standards, seriously investigate and deal with projects that are not designed and constructed according to green building standards within the scope of mandatory green building implementation, and guide real estate projects to be designed and constructed according to green building standards. To demonstrate the demonstration effect of the project and build a number of high-quality green buildings.
Prefabricated building boom
The "Planning" proposes to vigorously develop prefabricated buildings, speed up the construction of prefabricated building production bases, foster leading enterprises integrating design, production and construction; and improve the relevant policies, standards and technical systems for prefabricated buildings. Actively develop building structure systems such as steel structures and modern wood structures.
The development of prefabricated buildings is one of the methods for the construction industry to promote supply-side reform. In the "three to one, one drop and one supplement", the prefabricated building undertakes the responsibility of ecological civilization to complement the short-board and steel and cement industries, and the prefabricated building is bound to be Become an important focus of active fiscal policy.
In recent years, the relevant departments have issued a series of policies and measures to promote the development of fabricated buildings. The prefabricated buildings have gradually started, but the overall development is slow. Relevant data show that in 2015, the newly-built construction area of ??the country was less than 3% of the newly-built construction area. At present, the development of the domestic assembly-type construction industry faces multiple obstacles, including high cost, unclear policies, and low consumer acceptance. The mode is not clear and so on. The current policy pushes or can further reduce the cost of prefabricated buildings. In the future, the model that can integrate upstream and downstream resources and reasonably avoid the risk of "cheat" policy will stand out.
In February last year, "Several Opinions of the Central Committee of the Communist Party of China and the State Council on Further Strengthening the Management of Urban Planning and Construction" proposed that the proportion of prefabricated buildings in the newly built buildings in the country should reach 30% in about 10 years. At the end of September, the General Office of the State Council The issuance of the "Guiding Opinions on the Development of Prefabricated Buildings" indicates that the development of prefabricated buildings will become an important national policy to promote the transformation and upgrading of the construction industry. Subsequently, various localities have also issued policies to formulate specific development goals for fabricated buildings.
Relevant institutions carry out calculations and make conservative estimates based on the above objectives. The compound growth rate of fabricated buildings is at least 27%. It is estimated that by 2020, the total revenue of the industry will be 340 billion yuan and the total gross profit will be 80 billion yuan. In 2026, the total revenue of the industry will be 20 1.3 trillion yuan, total gross profit of 300 billion yuan.
Many people in the industry have also made suggestions on the development of fabricated buildings. It is mentioned that the improvement of the standard of fabricated building standards requires the promotion of mature technical systems and the acceleration of the general contracting of EPC projects to give full play to the comprehensive advantages of fabricated construction.
Green building materials welcome development opportunities
The "Planning" proposes to improve the construction of the green building materials evaluation system, and has steps and plans to promote the evaluation of green building materials. Establish a quality traceability system for green building materials, and dynamically publish a catalogue of green building materials to create a good market environment. Carry out demonstration of industrialization of green building materials, and give priority to the use of green building materials in projects invested by the government.
At present, promoting green building materials and developing green buildings has become the only way for the transformation and upgrading of the building materials industry.
However, there are still some problems in developing circular economy and promoting the development of green building materials. First, the scope of application is small and the proportion is low. According to preliminary estimates, the current green building materials only account for about 10% of the materials used in the construction industry, and the industrial scale is only about 350 billion yuan. Second, the standards are not perfect, and most of the existing product standard systems are not co-ordinated. Consider the indicators of green factors; third, the investment in new building materials is large, the company's funds are limited, and the development momentum is insufficient.
The development of green building materials is in the norm. Peng Shou, the representative of the National People's Congress and chairman of China National Building Material International Engineering Group Co., Ltd., supported the promotion of green building materials. He suggested that the Ministry of Housing and Urban-Rural Development introduces green building materials certification standards and certification systems, conduct energy efficiency audits, and compile green building materials catalogues. Standards, with standard norms as the starting point, give more powerful financial support to demonstration enterprises to promote the development and application of green building materials.
At the same time, set up special funds for the development of new building materials and circular economy, subsidize green building materials enterprises and green building projects, support the demonstration and promotion of green building materials technology and products, and support the implementation of major green building projects. Clearly enforce the scope of green building standards, for example, clearly stipulate the proportion of green buildings in new buildings, increase the promotion of green building materials and green buildings such as Low-E glass, thin film solar cells, and energy supply 5.0, and realize green building materials. Widespread application of the whole society.
The promulgation of this policy will affect the development of related industries and enterprises. Some analysts said that thanks to the continuous increase of policy promotion and the gradual arrival of financial support under the innovation model, enterprises in the fields of green building materials, renewable energy applications, door and window curtain wall, photovoltaic building integration and thermal insulation building materials will be in the future. It has achieved rapid development in five years.
In addition, the Plan also actively guides green construction. Promote green property management model. Focusing on the treatment and reuse of construction waste, we will strengthen the research and development, promotion and application of recycled building materials production technology, technology and equipment, and increase the proportion of construction waste resources utilization.
