Abstract

A better understanding of the material stock in the built environment is needed to reduce its climate and environmental impacts while also improving its circularity. We introduce a comprehensive, globally consistent method to estimate residential floor area and material stock at a fine-scale spatial resolution, using the latest publicly available datasets on key building parameters and material intensity. Applying our validation analysis for a selected number of countries and subnational regions, we found that our floor area estimations underestimated official statistics by 30–40 %. Comparing our material stocks estimations with various definitions of building typologies and results from other studies, we found some degree of variation. These results highlight the need for more strengthened and concerted efforts in filling data and research gaps in various world regions. Overall, the presented approach allows for more rapid and regionally specific assessments of the material stocks and related impacts to inform policy directions.

一种估算住宅建筑面积和材料存量的全球空间化方法

需要更好地了解建筑环境中的材料库存，以减少其对气候和环境的影响，同时提高其循环性。我们介绍了一种全面的、全球一致的方法，利用最新的公开数据集，在精细尺度的空间分辨率下估算住宅建筑面积和材料库存，这些数据集涉及关键建筑参数和材料强度。通过对选定的一些国家和次国家地区进行验证分析，我们发现我们的建筑面积估计低估了官方统计数据30 - 40%。将我们的材料存量估算与建筑类型学的不同定义和其他研究的结果进行比较，我们发现了一定程度的差异。这些结果突出表明，需要更加加强和协调一致地努力，以填补世界各区域的数据和研究空白。总的来说，所提出的方法可以更迅速地对物质存量和有关影响进行具体区域评估，以便为政策方向提供信息。

期刊介绍： The journal Resources, Conservation & Recycling welcomes contributions from research, which consider sustainable management and conservation of resources. The journal prioritizes understanding the transformation processes crucial for transitioning toward more sustainable production and consumption systems. It highlights technological, economic, institutional, and policy aspects related to specific resource management practices such as conservation, recycling, and resource substitution, as well as broader strategies like improving resource productivity and restructuring production and consumption patterns. Contributions may address regional, national, or international scales and can range from individual resources or technologies to entire sectors or systems. Authors are encouraged to explore scientific and methodological issues alongside practical, environmental, and economic implications. However, manuscripts focusing solely on laboratory experiments without discussing their broader implications will not be considered for publication in the journal.
