Residential building floor area

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 approach for a selected number of countries and subnational regions, we found that the derived floor area estimations marginally underestimated official statistics. Comparing our material stock 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.
