Green building is of great significance to both individuals and society
With the development of the economy and the continuous improvement of people’s living standards, green environmental protection has become a healthy and positive life goal pursued by everyone. Correspondingly, the development and application of green building materials has become an important business strategy to win market competition.
Green building materials that are both energy-saving and environmentally friendly can save energy, reduce emissions of waste-polluting gases, and make people’s living environment healthier and more comfortable. Both individuals and society have important significance and are an important way to achieve harmonious development between man and nature.
1. Criterion criteria for green building materials
According to the content of hazardous substances in the decorative materials or the amount released, it is lower than the ten standards of the “Restriction of Hazardous Substances in Building Materials” promulgated by the State. Can be refined into quality criteria, economic criteria, these two are common criteria for common material requirements. Quality is an important technical criterion for materials. It is necessary to examine whether the quality of materials can produce useful facilities. The economic criterion refers to the cost analysis and economic accounting of the production of materials. The greatest economic benefit is obtained with the least investment. The main purpose pursued.
2. Environmental criteria
According to the content of hazardous substances in the decorative materials or the amount released, it is lower than the ten standards of the “Restriction of Hazardous Substances in Building Materials” promulgated by the State. It can be refined into resource criteria and environmental criteria, which is a criterion especially emphasized by green building materials. The resource criterion means that the material of a unit product consists of the least resources or consists of more renewable resources, and the resources are minimized. The environmental criterion refers to the small pollution of the indoor environment during the use of the material, and the maximum protection. People's health.
3.green building materials selection
To ensure that the building environment is free of pollution, it will help consumers to be healthy; it is pollution-free and sustainable. The choice of green building materials must be selected from the following points:
(1) Non-toxic and harmless, chemical stability and bio-safety are good, avoiding greenhouse effect and ozone layer damage; for example, formaldehyde-free adhesive, large core board, veneer, and benzene are not selected on the decoration materials. Paint, gypsum board, etc.
(2) The whole life cycle has low resource consumption and high utilization rate; it can be recycled and reused easily; for example, the composite material with high utilization rate, renewable utilization and low resource consumption should be selected as much as possible on the decoration materials.
(3) The structure is stable and reliable; it has little environmental pollution during development and use, and can protect and purify the environment.
Green building materials are the only way for the sustainable development of the building materials industry. The greening technology of building materials such as recycled building materials will promote the greening process of building materials in China and should be vigorously developed. At present, it is also necessary to improve the systemic and well-operable green building materials evaluation methods and standards to guide the healthy development of green building materials.
