sustainable development
With the rapid development of economy, people's living standards are constantly improving, and the utilization rate of energy and resources is constantly rising. Many modern lifestyles are at the expense of the environment: excessive emission of greenhouse gases such as carbon dioxide into the atmosphere has led to a series of chain reactions such as greenhouse effect, global warming, melting glaciers and rising sea level with time; The use of refrigeration equipment such as air conditioners and refrigerators makes the air contain too many chemicals such as chlorofluorocarbons, which leads to a series of problems such as ozone layer destruction, ozone hole and enhanced ultraviolet radiation on the ground. On the surface, there are signs that our ecological environment is being destroyed and the balance between man and nature is being broken. To this end, we put forward the theory of sustainable development, which can not only meet the needs of contemporary people, but also do not damage the ability of future generations to meet their needs. Under this long-term economic growth mode, in the construction industry, we propose and promote the development of green buildings accordingly, and strive to coordinate the harmonious development of human life and ecological environment. Based on this, this paper discusses the green building and ecological environment.
1 green building
1. 1 The concept and connotation of green building are defined as follows in GB50378 "Evaluation Standard of Green Building": Green building refers to saving resources (energy, land, water and materials) to the maximum extent, protecting the environment, reducing pollution, providing people with healthy, applicable and efficient use space and living in harmony with nature.
From the definition of green building, we can see that the so-called green building can not only provide healthy, safe and comfortable internal living space for human beings, but also have an external architectural environment that can be in harmony with the natural environment.
We can understand and summarize the connotation of green building as follows: under the premise of saving resources and energy and reducing the pressure of buildings on the environment, we can provide healthy, safe and comfortable living environment and living space for human beings by using architectural schemes and technologies that can promote a virtuous cycle of ecosystems, do not pollute the environment and realize the harmonious and sustainable development of people, buildings and the environment.
1.2 green building design green building is a macro concept. How to grasp the definition of "green" as a whole, architects should not be limited to single buildings, but should start from the whole, focus on the overall situation, and put the green concept into the overall planning and design to think. Because many modern concepts and technologies are integrated into green buildings, such as effective sewage treatment, solar energy and wind energy collection and utilization. Many technical fields are beyond the knowledge and cognitive level of the construction industry, which requires architects to know a little about other related majors, communicate and learn with technicians and engineers of other related majors in time, and realize the development and rise of the green building industry under the cooperation of many parties.
Designers should strictly follow the basic principles of green building in practical work, and implement "four festivals" on the basis of respecting the ecological environment, that is, energy saving, land saving, water saving and material saving, so as to meet the needs of human beings for architectural functions and space and make architecture live in harmony with nature. To achieve sustainable development, we must first respect the local ecological environment, increase our understanding of the natural environment, and coordinate people's behavior with the development of the natural environment. According to local conditions, make use of all available elements and efficient use of natural resources, and correctly handle the dialectical relationship between energy saving, land saving, water saving, material saving, environmental protection and meeting building functions. In the early planning of architectural design, architects should formulate technical guidelines for green buildings, adopt simple and practical technologies and use energy-saving building materials. It is necessary to strengthen resource conservation and comprehensive utilization and avoid using building materials that are easy to damage the environment and produce waste; At the same time, we should also pay attention to regionality, respect national customs, and create green buildings with the characteristics of the times and regions according to local natural resources, economic conditions and climate characteristics.
2 ecological environment
2. 1 Concepts and problems of ecological environment The definition of ecological environment in environmental management is: ecological environment refers to the quantity and quality of water resources, land resources, biological resources and climate resources that affect human survival and development, and is a compound ecosystem related to social and economic sustainable development. Eco-environmental problems refer to all kinds of negative feedback effects caused by the destruction and pollution of the natural environment in the process of utilizing and transforming nature in order to survive and develop.
2.2 Eco-environmental protection The basic principle of eco-environmental protection in China is to pay equal attention to eco-environmental protection and eco-environmental construction. While strengthening the construction of ecological environment, we must adhere to the policy of giving priority to protection, giving priority to prevention and combining prevention with control, completely reverse the passive situation of destruction while building in some areas, and insist on paying equal attention to pollution prevention and ecological environment protection. It is necessary to give full consideration to the mutual influence and function of regional and river basin environmental pollution and ecological environment destruction, adhere to the unified planning of pollution prevention and ecological environment protection, implement it simultaneously, organically combine urban and rural pollution prevention and ecological environment protection, and strive to realize the integration of urban and rural environmental protection.
3 Green building and ecological environment
3. 1 Implementing green building is the need of 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 seriously damaged, it will have an adverse impact on human life. Therefore, in view of green buildings and ecological environment, the central government proposes to vigorously develop energy-saving and land-saving houses, popularize energy-saving technologies in an all-round way, and formulate and enforce energy-saving, land-saving, material-saving and water-saving standards in accordance with reduction, reuse and water-saving.
3.2 misunderstanding of green buildings
3.2. 1 Green does not mean high price and high cost. In recent years, green buildings and eco-environmental protection have been gradually understood and recognized by people, so many green buildings and eco-environmental protection have been gradually understood and recognized by people in recent years. So many people mistakenly think that green represents advanced technology and cutting-edge technology, thus invisibly equating "green" with high price and high cost. In fact, this understanding is one-sided and wrong. The green building we advocate is a broader concept, which does not mean high price and high cost. For contractors and developers, one of the goals is to reduce the cost of the building as much as possible, so if the overall cost is calculated from the perspective of the whole life cycle of the building in the long run, it is extremely cost-effective to adopt and utilize low-energy environmental protection building materials. For immediate benefit, materials with low cost but far-fetched quality and high energy consumption are used at the beginning of building construction. As a result, energy consumption and maintenance cost are often high, and the overall consumption is far greater than the use effect of low-energy environmental protection building materials. Therefore, with an eye to the future, it is imperative to advocate and develop green buildings in an all-round way by using low-energy environmental protection materials.
3.2.2 Green buildings are not limited to new buildings. Advocating green buildings is not just a model we adopt when building new buildings. It also covers the green transformation of old buildings and existing buildings, so that the original buildings can reach the relevant indicators of green buildings through corresponding energy-saving and environmental protection measures, thus achieving the purpose of protecting the ecological environment and sustainable development. Talking about the life elements such as water, electricity and gas which are closely related to the people in daily life. At present, water supply and power supply in most parts of our country have realized plug-in system. Users buy water cards and electricity cards and plug them in to get energy, which puts an end to stealing water and electricity by changing meters and strengthens people's awareness of saving. Collecting sewage treatment fee conforms to the national principle of "whoever pollutes will treat it" and also gives people the concept of environmental protection. In this regard, we also have a new idea for the measurement transformation of heating. In the past, collective heating left many families with windows open in winter, which was undoubtedly a waste of energy. It is economical and energy-saving, and conforms to the concept of ecological protection. As far as China's present situation is concerned, one of the current tasks is to comprehensively start the constitutional reform of heating in the north, and adopt a new heating constitution for newly implemented heating areas and heating cities; Second, in view of the grim situation of cultivated land protection in China, it is the first to implement the compact planning and design model of towns, communities and buildings in coastal areas; The third is to adjust measures to local conditions and strengthen the green transformation of local buildings.
3.2.3 Building energy conservation is not only the responsibility of the government, but also the ecological environment is closely related to everyone. Promoting green buildings is not only a political move of the government, but also a livelihood project. Therefore, to let people know what a green building is, it is either a green building with flowers, fountains and pools, or a well-afforested building. If ordinary people can pay attention to building energy conservation and green building, and pay attention to building energy consumption, materials, impact on indoor environment and carbon dioxide gas emission reduction, then everyone's knowledge will form the market demand for green building. With the market demand, building energy conservation and green building can be widely promoted and applied in the whole society.
