日内瓦，12月15日 – 开关ing from linear to circular ways of doing business could contribute to a substantial dent in emissions from the built environment. But what makes a building circular, and how do you measure progress? A 新论文 by the World Business Council for Sustainable 发展 (WBCSD) defines what companies need to measure, how to measure it and how to interpret the results to evaluate how circular a building is.
建筑环境的责任 37% 全球排放和 超过一半 占全球资源消耗总量的比例. A shift to a circular economy could make the built environment more sustainable, helping the sector reduce waste and pollution, keep products and materials in use longer and regenerate natural systems.
虽然这个行业 努力 变得更圆, there needs to be a standardized approach to measuring circularity in buildings, 另有, industry-wide adoption of circular practices will be hampered.
建在西文署的基础上 循环过渡指标方法, the 新论文 is a first step toward creating a unified framework, setting out key considerations for measuring circular buildings.
To reduce the complexity of measuring circularity in buildings, the authors suggest starting by analyzing different building layers and using consistent terminology, 这篇论文介绍了.
The authors further encourage companies to look at both qualitative and quantitative data when measuring the circularity of buildings and to consider circular principles like lifetime extension, 可拆离性, adaptability and flexibility throughout the building design phase.
Other key considerations highlighted in the paper include measuring circular inflows and outflows, which consists of monitoring the type of material, the percentage of reused and recycled materials and end-of-life recovery. 就这件事而言, 基准, standards and key performance indicators should be set and improved where existing.
除了关闭物料流动的循环, the authors recommend measuring water and energy inflows and outflows, together with close monitoring of the carbon life cycle, to ensure circular evaluations are complementary and not substitutive to environmental ones.
Roland Hunziker, Director, 建筑环境, WBCSD, 说, “Businesses must embrace a circular economy to achieve a nature-positive and net-zero built environment. But the industry has yet to establish common approaches to measuring the impact of circular solutions in buildings. This paper provides an important breakthrough in this field. Its conclusions and recommendations can support decision-makers working on building projects to develop business strategies to increase circularity. We encourage all built environment stakeholders to join us in the next steps of developing a shared framework for measuring circularity in buildings.“
The authors invite companies and peer organizations to share their feedback on the approach and key considerations explored in this paper during an open consultation phase from 15 December 2022 to 24 February 2023. 请 点击这里 提供你的意见.
