Ministry of Housing and Urban-Rural Development: In 2030, newly built buildings will fully implement green standards, with prefabricated accounting for more than 50%
Recently, the Ministry of Housing and Urban-Rural Development issued the "14th Five-Year Plan for Building Energy Conservation and Green Building Development", which clearly stated that by 2030, new buildings will fully implement green building standards, and prefabricated buildings account for more than 50%. This policy has quickly become the focus of hot discussion across the Internet. The following is a combination of hot topics and structured data in the past 10 days to interpret the key policies and industry impacts.
1. Core policy goals and time nodes
| index | 2025 goals | 2030 goals |
|---|---|---|
| The proportion of new green buildings | 100% | 100% (star improvement) |
| Prefabricated building proportion | 30% | More than 50% |
| Building energy consumption intensity is reduced | 10% | 15%-20% |
2. Top 5 hot topics on the entire network (next 10 days)
| Ranking | topic | Discussion volume (10,000) | Related Policy Points |
|---|---|---|---|
| 1 | "Can prefabricated construction cost be reduced?" | 142.6 | Prefabricated proportion target |
| 2 | "Green Building Subsidy Policy" | 98.3 | Star building motivation |
| 3 | "BIM technology application prospects" | 75.2 | Digital collaboration requirements |
| 4 | "Traditional building materials industry transformation" | 63.8 | Low-carbon material replacement |
| 5 | "Photovoltaic building integration case" | 51.4 | Renewable energy utilization |
3. Key measures for policy implementation
1.Standard system upgrade: The new version of the "Green Building Evaluation Standard" will be implemented from 2024, and mandatory indicators such as carbon emission calculation and health performance will be added.
2.Industrial chain support: Prefabricated construction projects will be rewarded with a floor area ratio of 3%-5%, and the procurement ratio of green building materials certified products shall not be less than 30%.
3.Technological innovation list: Focus on supporting the research and development of 12 technologies including modular construction and construction waste recycling, and complete the pilot demonstration before 2025.
4. Industry impact data forecast
| field | Market size in 2025 (billion yuan) | Compound annual growth rate |
|---|---|---|
| Prefabricated building | 2.8 trillion | 18.7% |
| Green building materials | 1.2 trillion | 25.3% |
| Building photovoltaics | 420 billion | 30.5% |
5. Excerpts of expert opinions
Wang Youwei of the Chinese Academy of Building Sciences said: "This policy will promote the transformation of the construction industry from 'high energy consumption' to 'negative carbon'. It is expected that by 2030, the entire life cycle of green buildings will be reduced by 4 billion tons of carbon dioxide." Zhu Jiusheng, president of Vanke Group, pointed out: "The cost of prefabricated construction has dropped to 1.2 times that of traditional buildings, and it is expected to achieve a flat cost after scale."
6. Challenges and suggestions
1.Regional Difference Problems: The production capacity of prefabricated buildings in the central and western regions is insufficient, and a cross-regional collaborative production network is needed.
2.Talent gap: It is expected that 2 million new industrial workers will be added in the next five years. It is recommended to carry out special training for "green construction craftsmen".
3.Regulatory innovation: Promote blockchain technology to realize full-process traceability of building materials carbon footprints and ensure the authenticity of data.
This policy marks the entry of China's construction industry into a new stage of comprehensive greening and will reconstruct the trillion-level industrial chain pattern. With the introduction of supporting rules one after another, the situation of industry reshuffle and technological innovation parallelism is inevitable.
