Many of the modern lifestyles are at the expense of the environment: the emission of excessive carbon dioxide, such as excessive carbon dioxide, into the atmosphere, which has led to a series of greenhouse gases, global warming, melting glaciers, rising sea levels, etc. The chain reaction; the use of refrigeration equipment such as air conditioners and refrigerators causes excessive levels of chemical substances such as chlorofluorocarbons in the air, causing a series of problems such as destruction of the ozone layer, ozone holes, and ultraviolet rays that are irradiated to the ground. All kinds of signs surface, our ecological environment is being destroyed, and the balance between man and nature is broken. Sustainable development has become a hot topic in the moment. Under this economic growth model focusing on long-term development, in the construction industry, the promotion of green buildings plays a vital role in coordinating the harmony between human life and the ecological environment.
First, green building
Green building concept and connotation In GB50378 "Green Building Evaluation Standard", the definition of green building is: green building refers to maximizing resource conservation (energy saving, land saving, water saving, material saving) during the whole life cycle of the building. To protect the environment and reduce pollution, to provide people with healthy, applicable and efficient use of space, and buildings that are in harmony with nature. Concrete price
From the definition of green building, we can see that the so-called green building is not only an internal living space that can provide human health, safety and comfort, but also an external building environment that can be in harmony with the natural environment.
Green building connotation We can understand and generalize as follows: to save resources, energy, reduce the pressure on buildings to load on the environment, and to use building solutions and technologies that promote the virtuous circulation of ecosystems, do not pollute the environment, and are efficient and energy-saving. Human beings provide a healthy, safe and comfortable living environment and living space, and ultimately achieve the goal of harmonious coexistence and sustainable development between people and architecture and the environment.
Green building is a macroscopic concept. How to grasp the definition of "green" as a whole, architects should not only be limited to individual buildings, but should start from the whole, focus on the overall situation, put the green concept Think about it in the overall planning and overall design. Because of the integration of many modern concepts and technologies in green buildings, such as the effective treatment of sewage, solar energy, wind energy collection and utilization. Many technical categories are beyond the knowledge level of the construction industry. This requires architects to know a little about other related professions. They are diligent in communicating and learning with other relevant professional technicians and engineers in a timely manner. Under the joint development and rise of the green building industry.

In the actual work, the designer should strictly abide by the basic principles of green building. On the basis of respecting the ecological environment, the designer will implement the “four sections”: energy conservation, land saving, water saving, and material saving, to achieve human satisfaction. The function of the building and the need for space, in order to harmonize the building with nature. To achieve sustainable development, we must first respect the local ecological environment, increase the understanding of the natural environment, and harmonize people's behavior with the development of the natural environment. Use all available factors and efficiently utilize natural resources to properly handle the dialectical relationship between energy conservation, land saving, water conservation, material conservation, environmental protection, and meeting building functions. In the early planning of architectural design, architects should develop guidelines for green building technology, using simple practical techniques and using energy-efficient building materials. It is necessary to strengthen resource conservation and comprehensive utilization, avoid the use of building materials that easily damage the environment and generate waste; at the same time, it should also pay attention to regionality, respect national customs, and create an era based on local natural resource conditions, economic conditions, and climate characteristics. Green buildings with characteristics and geographical features.
Second, the ecological environment
Eco-environmental concept and problem The definition of eco-environment in Environmental Management is: Eco-environment refers to the general term for the quantity and quality of water resources, land resources, biological resources and climate resources that affect human survival and development. It is related to society and economy. A sustainable ecosystem of sustainable development. The problem of ecological environment refers to the negative feedback effect of human beings on the survival and development of human beings, the damage to the natural environment and the harm caused by human beings in the process of utilizing and transforming nature.
The basic principles of China's ecological environmental protection: adhere to the ecological environment protection and ecological environment construction. While increasing the intensity of ecological environment construction, we must adhere to the priority of protection, prevention, and prevention and control, completely reverse the passive situation of construction and destruction in some areas, and adhere to both pollution prevention and ecological protection. The interaction and effect of regional and river basin environmental pollution and ecological environment destruction should be fully considered, the unified planning of pollution prevention and ecological environment protection should be adhered to, and implementation should be carried out simultaneously, and urban and rural pollution prevention and control should be organically combined to achieve urban-rural environmental protection integration. .
Third, green buildings and ecological environment
The implementation of green buildings is the definition of the ecological environment. From the above definition and analysis, we know that the ecological environment directly affects the quality of human life. If the ecological environment is severely damaged, it will be counterproductive to human life. Therefore, for green buildings and ecology. Environment, the central government proposed to vigorously develop energy-saving and land-saving housing, comprehensively promote energy-saving technologies, formulate and enforce energy-saving, land-saving, material-saving, water-saving standards, and do a good job in accordance with the principles of reduction, reuse, and resource utilization. Comprehensive utilization to achieve sustainable economic and social development.
Misunderstanding of green building
Green does not mean high price and high cost. Green buildings and ecological environment have been gradually understood and recognized by the people in recent years. Therefore, many green buildings and ecological environment have gradually been understood and recognized by the people in recent years. Therefore, many people mistakenly believe that green represents advanced technology and cutting-edge technology, thus equating “green” with high prices and high costs. In fact, this understanding is one-sided and wrong. The green building we advocate is a broader concept, it does not mean high prices and high costs. For the contractor and the development unit, one of the goals is to reduce the cost of the building as much as possible. If you look at the long-term perspective and calculate the overall cost from the perspective of the entire life cycle of the building, then adopt and use low energy consumption. The environmentally friendly building materials are extremely cost-effective. For the immediate benefit, in the initial construction of the building, materials with low cost but high quality and high energy consumption are used. As a result, in the process of use, the energy consumption is large, the maintenance cost is high, and the overall consumption is far greater than the low energy. The use of environmentally friendly building materials. Therefore, focusing on the future, it is imperative to promote and comprehensively develop green buildings with low-energy environmentally friendly materials.
Green buildings are not limited to the new building that promotes green building. It is not the only model we use when building new buildings. It also covers the green renovation of old buildings and existing buildings, so that the original buildings pass corresponding energy conservation and environmental protection measures. Achieve the relevant indicators of green buildings, so as to achieve the purpose of protecting the ecological environment and sustainable development. Speaking about the elements of life that are closely related to the people, such as water, electricity, and gas in daily life. At present, the water supply and power supply in most parts of China have realized the card insertion system. Users purchase water cards, electric cards, and use cards to access energy, which eliminates the behavior of stealing water and stealing electricity, and strengthens people's awareness of saving. The sewage treatment fee is in line with the principle of pollution control in the country, and the people have the concept of environmental protection. In this regard, we have new ideas for the measurement of heating. In the past, collective heating has caused many families to open windows for the winter in winter, which is undoubtedly a waste of energy. The implementation of single-family renovation, one household and one table, can stop indoor heating during work and business trips, that is, economic and energy conservation, in line with the concept of ecological and environmental protection. As far as China's current form is concerned, one of the tasks today is that the reform of the heating constitution in the north will be fully launched. For the new heating districts and heating cities, new heating physique should be adopted. Second, the arable land protection in China will be severe. The national conditions have taken the lead in implementing compact urban, community and architectural planning and design models in coastal areas; the third is to adapt local conditions and strengthen the local green renovation of buildings.
Building energy efficiency is not just the responsibility of the government. The ecological environment is closely related to everyone. Promoting green buildings is not only a political measure of the government, but also a project for the welfare of the people. Therefore, let the people know what green buildings are, not flowers, green grass, fountain pools, and green buildings are “green buildings”. If the people can pay attention to building energy conservation and green buildings, and pay attention to the energy consumption, materials, impact on the indoor environment, and carbon dioxide gas emission reduction, then everyone's consensus will form a market demand for green buildings. With market demand, building energy conservation and green building can be widely applied in the whole society.
