Green building?

In recent years, new terms such as "passive building" and "near-zero energy building" have appeared in the media frequently. As an imported product from the European region, which is a pioneer in carbon reduction, several pilot projects have been carried out in China.

These building forms belong to the category of low-carbon and energy-saving green buildings. 31 provinces across the country have clearly written "accelerating green and low-carbon development" into the "14th Five-Year Plan" document. Under the vision of carbon peaking and carbon neutrality, the enthusiasm for new energy investment and construction in various places is high. 31 provinces across the country have clarified "accelerating green and low-carbon development", and have written this into relevant documents of the local "14th Five-Year Plan".

What is green building?

Green building does not simply mean that the facade is covered with green plant decoration, it has more functions and meanings: in the whole life cycle of the building, it can save resources to the maximum extent, protect the environment and reduce pollution, and provide people with healthy, suitable and efficient use of space, a building that coexists in harmony with nature, while at the same time achieving the most efficient use of energy and minimal impact on the environment.

Significance of developing green buildings

From construction to operation, my country's construction industry carbon emissions account for about 40% of the total carbon emissions, and it is a veritable "big producer" of carbon emissions. With the acceleration of urbanization, due to the influx of a large number of people into cities, the demand for housing, roads, underground works, and public facilities is getting higher and higher, and the energy consumption is also increasing. The greenhouse gas emissions of the construction industry continue to rise. , oil and gas resources are increasingly scarce. Through the development of green buildings, we can provide human beings with a safe, healthy and comfortable living space, be in harmony with the natural environment, and achieve harmonious coexistence and sustainable development between people, buildings and the environment.

1) To minimize energy and resource consumption

Vigorously developing green buildings and promoting building energy conservation have important practical significance for the energy conservation and consumption reduction of the whole society, the construction of a resource-saving and environment-friendly society, and the realization of the sustainable development of the entire economy. With the concept of sustainable development and energy saving and environmental protection deeply rooted in the hearts of the people, green buildings have become the basic direction of the development of the construction industry.

2) Green buildings can provide a more comfortable living environment

Green buildings are ecological buildings and sustainable buildings. The ability of green building to provide a more comfortable living environment is determined by its own nature, and its content includes not only the building itself, but also the internal and external environmental ecological function system of the building and the construction of a safe, healthy and stable ecological service and maintenance function system for the community.

How to achieve green building?

1) Adopt green building materials
Green building materials are the basis for realizing low-carbon development of buildings, and play a leading and supporting role in energy conservation and emission reduction.

2) Process transformation
In the process of processing and production, clean technology is adopted to reduce unnecessary links and consumption, improve production efficiency and reduce the generation of pollutants.

3) Optimize the building structure
Professional assessment of buildings and structures and rational optimization to reduce resource consumption to minimize project costs.

4) Land saving measures
By improving the intensive rate of ground land use, improving the concentrated development of land use and optimizing the urban structure, the utilization rate of land can be improved.

5) Saving water and improving the utilization of water resources
Use water scientifically and rationally, implement water recycling, reuse water, and protect water resources.

6) Outdoor environment and pollution control

Green Building Evaluation Certification
Although the evaluation standards and evaluation mechanisms of the green building standard systems vary from country to country, the content of the evaluation and the factors of concern are mainly focused on reducing carbon emissions, saving and recycling energy resources, reducing energy consumption, sewage treatment, and garbage recycling. , outdoor environment, indoor environment, etc. China's green building certification evaluation includes the following points:

1. Land saving and outdoor environment
2. Energy saving and energy utilization
3. Water saving and utilization of water resources
4. Material saving and utilization of material resources
5. Indoor environmental quality
6. Operation management (residential buildings), comprehensive performance of the whole life cycle (public buildings)

Since the 1980s, green buildings have developed from the first generation of energy-efficient buildings, to the second generation of green buildings that focus on buildings and the environment, to the current third generation of green buildings that integrate "people-oriented". From a higher level of ecological civilization, we should re-establish a new relationship of friendship, harmony and symbiosis between architecture and nature, and realize the goal of combining architecture with "long-term development of human beings".
