Abstract
The data record contains Material Intensity data for buildings (MI). MI coefficients are often used for different types of analysis of socio-economic systems and in particular for environmental assessments. Until now, MI values were compiled and reported ad-hoc with few cross-study comparisons. We extracted and converted more than 300 material intensity data points from 33 studies and provide the results in a comprehensive and harmonized database. Material intensity is reported as kilograms per gross floor area for 32 materials as primary data points. Furthermore, we augmented the data with secondary attributes for regional information, such as climate and socioeconomic indicators. The data are hosted on the version control platform GitHub using accessible data formats and providing detailed contribution guidelines. This “database seed” facilitates data analysis, accessibility, and future data contributions by the research community. In the Technical Validation we illustrate that consistency of the data and opportunities for further analysis. This database can serve scientists from various disciplines as a benchmark to determine typical ranges and identify outliers.

Background & SummaryConstruction materials, including metals such as steel, copper, and aluminum, and non-metallic minerals such as concrete and ceramics, are responsible for around 40% of annual global resource flows[1,2]
Quantifying material stocks and flows has been an ongoing challenge because the masses of construction materials are inconsistently measured and reported in statistics
Equation 1 illustrates the overall concept to determine the total stock MS of material m in end-use i at time t, as a product of the inventory INV times the material intensity coefficient
Summary
Background & SummaryConstruction materials, including metals such as steel, copper, and aluminum, and non-metallic minerals such as concrete and ceramics, are responsible for around 40% of annual global resource flows[1,2]. Quantifying material stocks and flows has been an ongoing challenge because the masses of construction materials are inconsistently measured and reported in statistics. It is possible to estimate the total mass by multiplying the inventory with a known ratio of material mass per unit of inventory (see Equation 1). These ratios are often termed material intensity coefficients (MI) and can be obtained in different ways. Equation 1 illustrates the overall concept to determine the total stock MS of material m in end-use i at time t, as a product of the inventory INV times the material intensity coefficient
