The significance of wood structure building in energy-saving and environmentally friendly green buildings!

Author: Time:2019-03-20

Summary of information:

First, the wood-made building will provide people with a warm, natural, healthy and comfortable living place.

Wood is a green material. It has beautiful texture and rich colors. It has good sound absorption and sound insulation. A variety of woods can emit special aroma, which is good for health and can resist the harm of many kinds of organisms.According to Japanese scholars, the average life expectancy of living wooden houses is 9 to 11 years older than those living in reinforced concrete buildings. 90% of the materials used in general housing in the United States are wood.

Second, it will greatly promote the development of China's timber industry and improve its technical level.

Housing construction is a major consumer of wood.According to statistics, in 2001, the total consumption of wood in China was about 250 million cubic meters, of which construction and house decoration materials were 54 million cubic meters, accounting for 21.6% of the total, while developed countries generally average 30% to 50%. When China's construction timber consumption reaches this level, the processing volume of the timber industry will increase year-on-year.Existing wood products, such as logs, board squares, and wood-based panels, will not only increase in quantity, but also improve quality requirements.Emerging wood engineering composites (referred to as engineering wood) will surely come into being. Therefore, China's wood processing technology must be comprehensively improved on the basis of existing ones to meet the needs.

Third, it will be conducive to the rapid development of fast-growing and high-yield timber forests.

Practice has shown that in many cases, afforestation is more economical than planting crops, and the country has started the construction of fast-growing and high-yield forest bases, giving forest farmers many preferential policies, such as fiscal interest subsidies, credit priority, and loose logging, which will surely attract all kinds of The enthusiasm of enterprises, forest farmers, etc., and accelerate  he development of  timber forests usage.This is beneficial to the supply of raw materials for building materials enterprises and to the development of ecological construction. It is of great significance for the combination of resource cultivation, processing and utilization, and the development of industry and ecology.

Fourth, good for environmental protection
Wood is the main building material for renewable, and the wood  has the least impact on the environment compared to other structures material  in terms of energy utilization and air and water pollution.In terms of energy consumption, the concrete structure is 2.2 times that of the wood structure, and the steel structure is 1.5 times that of the wood structure;Steel and concrete structures produce 1.2 times and 1.5 times more greenhouse gases than wood structures, respectively.The air pollution index of the wood structure is the lowest, the air pollution generated by the steel structure is 1.7 times that of the wood structure, and the concrete structure is 2.2 times.The wood structure has the lowest impact on water toxicity, the steel structure is 3.47 times that of the wood structure, and the concrete structure is 2.15 times.
