轻型木结构房屋碳排放总量计算方法研究

Calculation Method Determination of Carbon Dioxide Emissions for Light Frame Wood Houses

从国内外对努力降低二氧化碳排放量的共识出发,简单介绍了轻型木结构房屋应用情况和碳排放计算的国内外研究现状,考虑到木材的负碳效应,将轻型木结构建筑全生命周期划分为木材生长阶段、建筑材料生产阶段、建筑施工阶段、建筑使用阶段、建筑拆除和处理5个阶段,分别给出了各个阶段二氧化碳排放量的计算公式,为轻型木结构房屋二氧化碳排放定量计算提供方法。研究的方法和得到的启示对其他类型的木结构具有广泛的借鉴意义,为今后相关研究的发展指明了方向。

The reduction of carbon dioxide emissions is already a consensus view abroad. This article gives a brief introduction to research and application status of light frame wood houses and the calculation of carbon emissions. Taking into account the effect of the negative carbon of wood, the life cycle of light frame wood construction can be divided into five phases： timber growth phase, construction materials produetion phase, construction phase, building use phase, building demolition and disposal. The calculation formulas of carbon dioxide emissions for each stage were given, and it is help to providing a quantitative method of carbon dioxide emissions calculation for light-timbered houses. The research methods and the resulting revelation have extensive reference to other types of wooden structure and to point out the direction for the future development of relevant studies.
