In the 1990s, sustainable development became the choice of many countries. In this context, the concept of green building has gradually become popular. With environmental protection products gradually becoming the protagonist in the market, consumers have raised safety, health, and low carbon requirements for building materials. The promotion and application of green technologies and the use of environmentally-friendly construction materials that are pollution-free, non-polluting, and non-radioactive are inevitable trends in the development of the construction industry.
Causes of pollution from traditional building materials With the continuous improvement of living standards, people are paying more and more attention to the built environment. However, some traditional building materials are made of chemical materials and contain toxic substances. This building material continuously releases toxic gases to the interior and is harmful to human health. According to media reports, experts from the US Environmental Protection Agency have conducted sampling inspections on 10 newly-built houses. The test results show that there are more than 500 chemical substances in the indoor air of the building, which is many times higher than the outdoor.
The results of the study showed that asbestos and alfalfa are found in 2% to 3% of houses, and about 10% of houses contain viruses, bacteria, and other microorganisms. Buildings with these harmful substances inside are called "disease buildings." These "illnessed" buildings will spread their "diseases" to the users of the houses. Facts have proved that various hazardous substances released from inferior building materials are very unfavorable to human health. The high temperature inside the enclosed building provides an environment conducive to bacterial growth and greater harm to the human body.
The application of environmentally friendly building materials For a long time, we have always believed that China is a country with vast land and resources, and believes that Chinese people have abundant natural resources. In fact, China’s per capita natural resource share is far below the world average. How to make more Chinese entrepreneurs and ordinary residents realize the importance of energy conservation is worth thinking about for everyone.
In 2003, there were very few energy-saving and environmentally-friendly buildings in Shanghai. Most people have become accustomed to the cold winter and hot summer conditions and have no clear understanding of green buildings. Today, with the strong support of the government and vigorous promotion, Shanghai's energy-saving and environmental protection buildings have gradually increased and made remarkable achievements. Expo 2010 Shanghai World Expo Pavilion, Oasis Shigewei Garden Hotel, Zhangjiang Kewen Exchange Center, Pujiang Zhigu Investment Service Building, Qingpu Villa, Putuo District Old House Renovation Project, and a series of new and reconstructed energy-saving buildings are more energy efficient than ordinary buildings in Shanghai. 75%.
The development of green building materials Green buildings are buildings that use resources effectively, that is, buildings that are energy-efficient, environmentally friendly, comfortable, and healthy. Green building selection of building materials should follow the following two principles: one is to use 3R (Reduce, Reuse, Recycle, reusable, recyclable, renewable) as much as possible; the other is to use non-toxic, harmless, non-selective The materials and products that pollute the environment and benefit people's health are preferably materials and products that have national environmental protection signs.
Compared with traditional building materials, new building materials can not only reduce building energy consumption, but also make rational use of industrial waste. New building materials will not only not pollute the indoor environment, but also benefit human health, help to improve the built environment, can play anti-mildew, sound insulation, heat insulation, sterilization, temperature control, humidity control, dimming, flame retardant, deodorant effect. The production process of new environmentally friendly building materials will not cause pollution to the environment, will not generate new waste, and most of them can be recycled.
Judging from the market situation in China, most companies do not understand whether the building materials they produce or sell meet national standards, let alone produce or sell building materials according to national standards.
The modern society has developed economy, and the scale of infrastructure and housing construction is getting bigger and bigger. The mass production and use of building materials has provided material protection for the improvement of human living environment, but it has also paid the price of excessive energy consumption and serious environmental pollution. Therefore, if you want to protect the environment and achieve sustainable building design, you must incorporate the impact of raw materials on the environment into the standard system for measuring building value. Buildings come from nature and return to nature. The materials they use should not cause harm to the human body and the surrounding environment. Take clay bricks as an example, the production process will destroy the soil environment.
From a sustainable development point of view, the use of wood in buildings should be more cautious. The massive tree felling will lead to a series of problems, such as increasing the energy consumption of transportation, destroying the local economic environment and the ecological environment. Environmentally-friendly buildings should have excellent durability, be easy to maintain and manage, and not release or release harmful substances. In order to achieve the goal of sustainable development and minimize the negative impact of construction materials on the environment, it is necessary to develop pollution-free construction technology and environmentally friendly construction materials. For example, industrial waste (fly ash, slag, coal gangue, etc.) is used to produce building materials such as cement and blocks, waste plastic foam is used to produce heat-insulating wall panels, and waste glass is used to produce veneer materials. This practice can use industrial waste, reduce environmental pollution, and save natural resources.
Energy-saving and environmental-friendly materials will become the mainstream of energy-saving and environmental protection materials in the construction field. They have been widely used and will become the mainstream in the market in the future. It is understood that Europe has now set off a wave of construction. People expect that the future houses will not only be self-sufficient in energy, but will also be able to input the remaining energy into the grid. This is the new requirement that people put forward to the construction industry.
The use of environmentally friendly building materials has injected "fresh blood" into the construction industry. Environmental protection building materials not only solve the problem of environmental pollution that people are generally concerned about, but also realize the rational use and recycling of resources, making the building more perfect in design and construction.
Green building is based on environmentally friendly materials. By vigorously promoting the use of environmentally-friendly building materials, using modern high-tech tools for design and construction, and adopting pollution-free production technologies, sustainable development of buildings will gradually become a reality. Green building is a building that is consistent with the concept of sustainable development. It is a product of harmonious coexistence between mankind and nature, and a symbol of human civilization. We must consciously protect the living environment, create a good living environment, and create a harmonious green home.
