In recent years, my country’s construction industry has developed rapidly, but the extensive growth of the number of buildings is the main reason. The problem of resource consumption in the construction and use of buildings is serious. It is facing the challenges of promoting low-carbon, environmental protection and energy saving to the sustainable development of buildings. .

In fact, "green buildings" have existed in China since ancient times. Ancient Chinese documents have this record: "In ancient times, there were few people but many animals and animals. There were no more animals, insects, and snakes. There were sages and woods as nests to avoid group harm." , The "nest" mentioned in the article is the early green building. Our ancestors took local materials and made full use of natural conditions without causing major impacts on the surrounding environment. In the 21st century, China’s green building technology is becoming more and more mature, and many green demonstration projects have appeared. When designing architectural schemes, combined with the appearance design of the building, many modern advanced technologies, such as solar photovoltaic power generation technology, breathing wall technology, and passive Solar heating technology, fair-faced concrete construction technology, basement soil cold energy, green plants cooling, etc., so that the building can achieve the functions of environmental protection, energy saving, and zero energy consumption.

The main point of green buildings is to provide people with a comfortable and healthy living and working environment, save resources, protect the environment, and realize the harmonious symbiosis of architecture, man and nature. The design features of green buildings mainly include the following aspects:

1. People-oriented

This is the basic principle of green building design. Energy conservation and environmental protection cannot be pursued at the expense of human health and quality of life.

2. Save energy

Use renewable natural resources, such as solar, wind, and geothermal energy, to reduce building energy consumption. At the same time, as much as possible to choose renewable, easily degradable building materials, such as bamboo materials. In addition, the quality of building materials must be strictly checked to ensure that the materials used are pollution-free and radiation-free. In the design of green buildings, we must integrate reality and not sacrifice economic benefits in order to ensure "greenness".

3. Back to nature

In the design of green buildings, the surrounding environment must be fully considered and coordinated as much as possible to achieve the purpose of protecting the ecological environment. According to the actual situation, the renewable energy provided by the environment can be used, and the water body and vegetation around the building can be used to adjust the microclimate, so as to achieve the purpose of improving the thermal environment.

4. Harmony-oriented, overall design

As a result of human behavior, buildings have an impact on the environment during the whole life of their construction and use and demolition. Therefore, paying attention to its life cycle can not only provide people with a healthy and comfortable living space, but also have little impact on the environment after demolition. The demolition materials can also be further recycled. At the same time, the design of green buildings should emphasize the overall design thinking, comprehensively consider factors such as economy, culture, climate, etc., to achieve a perfect organic system with the surrounding environment. For example, in cold regions, if the thermal insulation performance of the windows is not good, even the use of expensive wall insulation materials will not achieve the effect of energy saving.

In today's architectural design, it is necessary to integrate energy and resource conservation, effectively increase the use of resources and energy, and more use of new materials, new technologies and new architectural design methods, and use of natural landscape and The harmonious combination of the building itself realizes a truly ecological and green zero-energy building.
