建筑围护用无机轻质墙板生命周期环境友好性评价指标的研究

Evaluation Index about Environmental Friendliness across Life Cycle of Inorganic Light Wallboards used Building enclosure

无机轻质墙板目前在我国应用范围很广,但由于技术参次不齐,造成了资源和能源消耗较大,并产生一定的环境污染,因此,需要建立相应的评价体系对该类产品进行环境友好性评价,以鼓励新技术和新产品的发展,减少资源使用和环境污染。项目主要采用全生命周期的评价方法对无机轻质墙板进行了环境友好性评价的研究,建立了板材产品环境友好性评价指标体系,并阐述了指标选取的方法和原则,为环境友好型产品的评定提供了指标基础,为无机轻质墙板的优选提供技术支持。

The application range is very wide about inorganic light wallboards in our country at present. But uneven levels on technology cause a great consumption of the resource and energy, and the environmental pollution is produced, too. So it is needed to set up a corresponding evaluation system for evaluating the environmental friendly products. It may encourage the development of new technology and new products, and reduce used resource and environmental pollution. The evaluation method about whole life cycle is adopted to research the evaluation of environmental friendliness for inorganic light wallboards in this project,and the product evaluation index system of environmental friendliness is established, and the method and principle of index selection are expounded, it offers the foundation on evaluating environmentally friendly products. It can provide technical support for the optimization of inorganic light-quality wallboard.
