Abstract

Building stock modelling underpins energy and environmental assessments of the built environment. Material Intensity (MI), representing material mass per unit dimension, is vital for bottom-up estimation of building material stocks. However, reliance on sparse or uniform MI data can lead to significant inaccuracies due to intra-archetype variability, often stemming from differing building morphologies. This paper develops a geometry-informed MI (GIMI) method to characterise MI variability using machine learning and morphology features, applied to four materials—brick, concrete, mortar, and stone—in Sheffield, UK. Results indicate that GIMI reduces potential material uncertainties by up to 18% compared to conventional unitary MIs. This approach enhances bottom-up building mass accounting, advancing a circular economy and low-carbon building sector.

几何材料强度揭示了英国住宅原型材料的相当大的可变性

建筑存量模型是建筑环境的能源和环境评估的基础。材料强度（MI）表示单位尺寸的材料质量，对于自下而上估算建筑材料库存至关重要。然而，依赖稀疏或统一的MI数据可能会由于原型内部的可变性（通常源于不同的建筑形态）而导致显著的不准确性。本文开发了一种几何信息MI （GIMI）方法，利用机器学习和形态学特征来表征MI的可变性，应用于英国谢菲尔德的四种材料——砖、混凝土、砂浆和石头。结果表明，与传统的单一MIs相比，GIMI减少了高达18%的潜在材料不确定性。这种方法加强了自下而上的建筑大规模核算，促进了循环经济和低碳建筑行业的发展。

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.
