Building cities with wood would store half of cement industry's current carbon emissions
Buildings around us create one-third of global greenhouse gas emissions -- that is about ten times more than that of air traffic worldwide. In Europe alone about 190 million square metres of housing space are built each year, mainly in the cities, and the amount is growing quickly at the rate of nearly one percent a year.
A new study has found that shifting to wood as a building construction material would significantly reduce the environmental impact of building construction. If 80% of new residential buildings in Europe were made of wood which was used in the structures, cladding, surfaces, and furnishings of houses, the buildings would store 55 million tons of carbon dioxide a year. That is equivalent to about 47% of the annual emissions of European cement industry.
For the development and progress direction of contemporary construction industry, greening has always been one of the most important topics, with emphasis on whether it can effectively improve the ecological environment quality in urban areas, control various hazards caused by pollution, and build a healthy urban environment for people.
Nowadays, the building materials market has also developed in an all-round way, and the types of materials for exterior wall insulation are also increasing. Relatively, the practical application difficulty of various technologies in the construction industry also shows an increasing trend.
In order to better highlight the important role of insulation materials for green buildings, a paper published in the journal of Insight - Material Science explored the application of exterior wall insulation materials with strong energy-saving ability in green buildings.
The author thought that for the external wall insulation of new buildings, there are significant differences in the actual effects of using different materials and matters, which needs the public’s attention. In practical application, both construction personnel and architectural designers need to start from their own work experience and refer to the local climatic conditions, building uses, construction location and other basic conditions to determine the functional requirements of thermal insulation materials and select the corresponding materials. On this basis, people engaged in building materials research need to invest more in innovative research, deepen the existing production methods and performance enhancement methods of environmental protection materials as much as possible, and continuously improve the energy-saving effect in the field of building materials, so that buildings can make better contributions to society.
