Assessing Material Efficiency and Impacts in Buildings (AMEIB)

除非建筑业迅速转变其生产和使用的材料，否则它仍将陷入环境影响失控的不可持续的轨道上。到2050年，仅水泥生产就可能占到所有人为二氧化碳排放量的三分之一，而目前这一比例约为8%。建筑材料(水泥、混凝土、砖、钢等)该项目-评估建筑材料效率和影响(AMEIB)-解决了可持续地改变建筑环境中材料使用的这一挑战，重点关注建筑和所有主要建筑材料。AMEIB将开发一种新的多尺度物质流影响分析(MFIA)算法，直接和定量地整合资源可用性、工业生态学和材料科学。MFIA算法的应用将确定在英国各地建筑中接近最高效率和最小生命周期环境影响(例如，二氧化碳排放)的场景和材料。这些结果将对通过材料效率措施减少与建筑相关的影响的程度进行基准测试，为政策制定者提供指导，为工业提供低影响技术，为材料科学家提供研究目标。AMEIB发现的新系统和材料将开创“材料效率城市”的先河。AMEIB为后续工作奠定了基础，以便在全球以及所有工业部门应用这种MFIA方法。因此，AMEIB为全面分析和实施建筑环境中的材料效率、合理管理全行业的资源使用和影响以及“可持续城市发展”迈出了重要的一步。

The construction industry remains locked onto an unsustainable trajectory of runaway environmental impacts unless it rapidly transforms the materials it produces and uses. Cement production may alone comprise a third of all anthropogenic CO2 emissions by 2050, up from ~8% today. Construction materials (cement, concrete, bricks, steel, etc.) are mainly used in buildings.This project - Assessing Materials Efficiency and Impacts in Buildings (AMEIB) - addresses this challenge to sustainably transform materials use in the built environment, focusing on buildings and all major construction materials. AMEIB will develop a novel multiscale material flow impact analysis (MFIA) algorithm that directly and quantitatively integrates resource availability, industrial ecology, and materials science. Applications of the MFIA algorithm will identify scenarios and materials that approach maximal efficiency and minimal life cycle environment impacts (e.g., CO2 emissions) in buildings, across the UK. These results will benchmark the extent to which impacts related to buildings can be reduced through materials efficiency measures, providing guidance to policymakers, low impact technologies for industry, and research targets for materials scientists.The novel systems and materials uncovered by AMEIB will pioneer the 'materials efficient city'. AMEIB lays the foundation for follow-up work to apply this MFIA approach globally and also across all industrial sectors. Therefore, AMEIB provides a significant step towards holistic analysis and implementation of materials efficiency in the built environment, rational management of industry-wide resource use and impacts, and also 'sustainable urban development'.
