Analysis on the Present Situation, Problems and Suggestions of Contemporary Green Buildings in China?

The following is the related content about the current situation, problems and suggestions of contemporary green buildings in China brought by Zhong Da Consulting for your reference.

In recent years, with the rapid economic development in China, building a resource-saving and environment-friendly society has become the general trend and the aspiration of the people. Everyone is concerned about the form of global climate change. In the field of architecture, in order to realize energy saving and emission reduction, many cities in China regard green buildings as the strategic goal of urban development, which is of great significance and arduous task.

First, the analysis of modern green buildings

1. 1 building life cycle

The construction process starts from the planning and design stage of the building, and goes through construction, operation and management until the building is demolished. The process is not limited to the above stages, but also includes the extension in a deeper sense, such as the production and application of building materials, and the recycling of waste building materials after building demolition. Therefore, the concept of the whole life cycle of architecture is a positive expression of the sustainability of architecture in time, which should be given enough attention in the whole process of architecture.

1.2 meets the building function.

Healthy, applicable and efficient space also embodies the principle of sustainable development. Traditional buildings can only meet the most basic functions, while green buildings require certain flexibility and variability to meet people's different needs in different time periods; And on the premise of not losing people's comfort, it saves energy and improves the building function and use efficiency.

Harmony between architecture and nature

The traditional building model with high consumption and pollution will be replaced by the green building model that meets the needs of modern eco-city construction and development. Building energy consumption accounts for nearly 1/3 of the total social energy consumption, and the environmental pollution caused by building materials and construction production is also increasing day by day. Advocating saving resources, protecting the environment and reducing pollution embodies the policy of "saving energy, land, water, materials and environment". Therefore, green building is of great significance to the sustainable utilization of social resources and the improvement of the sustainable development of the environment. Saving energy and resources, reducing CO2 and pollution, the building itself is a big energy consumer, and it also has a great impact on the environment. According to statistics, 50% of the global energy is used for buildings, and at the same time, more than 50% of the raw materials obtained by human beings from nature are also used to build various buildings and their ancillary facilities. Although roads, bridges and tunnels cannot be measured by green buildings, residential areas, office buildings and apartments all use resources repeatedly. The ultimate goal of green building is to realize the harmony and harmonious life among people, nature and architecture.

Second, contemporary China's green building development confusion

2. 1 Lack of means to build and promote energy-saving buildings

At present, the contemporary green buildings in China only rely on the government's propaganda on energy-saving buildings. In this way, the focus will only be limited to public buildings, and rural and civil buildings will not receive much attention. Some government officials only see immediate interests, starting from short-term behavior, and always respond to difficulties with a negative attitude of escape. Therefore, the promotion methods of green energy-saving buildings are relatively scarce. However, if the government's compulsory measures are abandoned in the construction of building energy efficiency, the development of building energy efficiency will inevitably be wasted. Today and in the next few years, there are still many difficulties to be overcome in carrying out energy-saving work in green buildings, but we still have to rely on relevant energy-saving norms, rely on official coercion, and improve relevant legislation and law enforcement to form an energy-saving leading role in people's living habits, so that everyone can benefit from their daily energy-saving habits. For example, it will be acceptable to turn garbage into biogas to facilitate residents' lives, reduce the use of chemical fertilizers, increase farmers' income and improve people's health index.

2.2 There are differences in the promotion and application of green buildings.

The differences in the promotion and application of green buildings are mainly manifested in the following two aspects:

(1) North-South Difference of Green Building

The energy-saving work of green buildings started from the heating residential buildings in the north, because 20 years ago, heating energy consumption was the main part of building energy consumption, and there were no relatively complex residential buildings. However, with the rapid economic development in the south, especially in the southeast coastal areas and the middle and lower reaches of the Yangtze River, people's requirements for improving the thermal environment of buildings are also increasing. In addition, the building cooling and heating expenditure in the south is different from that in the north. At first, it was the residents who bore the cost of the south. Therefore, we say that the individual's economic interests can reflect the building energy saving in the southern region, which leads to the difference between the north and the south of green buildings today.

(2) The difference between rural and urban green buildings.

Compared with cities, the industrial structure in rural areas is relatively simple, and people's awareness of energy conservation has not been well popularized. They only rely on traditional frugal living habits and years of experience to avoid waste, and have little interest in paying attention to energy-saving buildings, let alone using scientific and technological means to implement energy conservation; However, there are relatively abundant energy-saving means in cities, and some energy-saving materials and intelligent systems have long been used in them, supplemented by many high-tech products. However, the promotion of green energy-saving buildings is more suitable for rural areas, because the population density in rural areas is relatively low and the natural environment is better; At the same time, the energy density in rural areas is not high, and the cost and transportation cost of conventional commodity energy are higher than those in cities. Therefore, rural energy should adopt green building energy-saving solutions completely different from urban energy, resulting in the difference between rural and urban green buildings.

Third, the way out for China's green buildings in the future.

3. 1 Enhance the whole society's understanding of green buildings.

Strengthen resource conservation and comprehensive utilization, reduce environmental load and create a comfortable and healthy environment. Publicize the theoretical basis, design concept and technical strategy of green building, and promote the popularization and application of green building; Establish green building concept dissemination, new technology and new product display, education and training base, and popularize green architectural knowledge by using newspapers, television, internet and other media to improve people's correct understanding of green building and avoid using building materials that are easy to damage the environment and produce waste; Improve the flexibility of building space, insist that the smaller the better, and minimize the resources and unfavorable factors of construction and operation; Reduce the damage to the environment in the construction process, provide a comfortable space environment for all, establish a sense of saving and a correct view of consumption, and form a good social atmosphere.

3.2 Research and promote the green building in line with China's national conditions.

In today's China, people's income is not high, so when we adopt green building standards and technologies, we should fully consider the construction cost and use cost of buildings, and stipulate that the technologies, products and facilities used in green buildings should be low-cost. For example, caves in Yan 'an, which are warm in winter and cool in summer, are unique representatives of traditional residential buildings in northwest China. Its cost is not high and it can be completely transformed into a Chinese-style green building. The promotion of these typical rural green buildings can be based on local conditions and local materials, and its cost is relatively low, which is more easily accepted by the people. Another example is some energy-saving technologies and equipment with high return on investment, such as energy-saving lamps, energy-saving air conditioners, water-saving toilets and solar water heaters. Once users use these technologies and equipment, they can minimize the expenditure on energy costs such as electricity and water, and generally recover the increased costs within 5-8 years. This kind of green building and energy-saving technology is in line with China's national conditions, and it is more easily accepted by ordinary people in China, so it can be widely popularized and applied in China.

3.3 Green buildings should pay attention to regionality and respect national customs.

Green buildings should pay attention to regionality and respect national customs. Adopting local culture, local raw materials, making full use of local building resources according to local natural resource conditions, climate characteristics, economic conditions and other factors to reflect regional characteristics, each nation and region has its own unique natural and human resources, and creates green buildings with regional characteristics and characteristics of the times according to local conditions. In building construction, combining with the actual use of some resources, the characteristics are among them. At the same time, we should respect the local history, strengthen the protection and reuse of the built environment and historical context, and try our best to integrate local unique cultural customs into the building.

Four. Concluding remarks

Green building can improve the use comfort, save resources, reduce the energy consumption in the process of construction and use, and reduce the environmental load, which is of great significance for improving the economic benefits of buildings, solving the energy crisis and realizing the sustainable development of human society. The majority of construction workers must master the concept of green building design in architectural design and implement it in construction, so as to achieve good economic and environmental benefits.
