Variations emerged between locations, household profiles and ownership types. Urban households exhibited lower embodied emissions per resident, but higher annual operational emissions (1500–1900 kg CO₂/resident), compared to rural households, which showed greater overall variation (1200–2200 kg CO₂/resident). Ownership patterns were less geographically distinct but stratified by type: mixed-ownership buildings exhibited the highest embodied energy, largest material stock and the most modern buildings, whereas community-owned buildings showed the widest variation in annual operational emissions (1500–2300 kg CO₂/resident). Our findings suggest that tailoring emission-reduction interventions to specific social and physical housing contexts would enhance the materials-energy nexus in the built environment. We discuss avenues for reducing energy losses, closing material loops, and incorporating sufficiency into building stock management.falseBuilding stock analysisEmbodied carbonEnergy-materials nexusMaterial coefficientsOperational emissionstext::journal::journal article::research article
