Abstract

This paper introduces the Housing Passport knowledge graph (HPKG) as a novel digital standardization framework with a robust semantic data infrastructure to promote a circular economy in the home-building industry. Unstandardized and dispersed housing data impedes a comprehensive assessment of housing stock characteristics and life cycle impacts, hindering the implementation of circular economy principles. The HPKG addresses this challenge by providing (1) a standardized framework for integrated analysis of residential buildings’ affordability and circularity across various spatiotemporal scales and socioeconomic contexts, and (2) a scalable semantic infrastructure using web ontologies that enhances the sharability, searchability, readability, and interoperability of housing-related data. A case study involving five Canadian cities demonstrates the HPKG's effectiveness in semantically linking and standardizing approximately 62 million data points representing over 1.2 million residential buildings. The results show how the HPKG enables a multi-scale integrated assessment of Canadian housing stock, focusing on affordability, energy efficiency, and environmental footprints. As a key conclusion, the HPKG supports informed decisions regarding housing stock by enabling the exploration of circular economy scenarios that prioritize the reuse and recycling of residential building materials. The HPKG empowers stakeholders to develop residential typologies that promote affordability, circularity, and sustainability across diverse socioeconomic contexts.

期刊介绍： Sustainable Cities and Society (SCS) is an international journal that focuses on fundamental and applied research to promote environmentally sustainable and socially resilient cities. The journal welcomes cross-cutting, multi-disciplinary research in various areas, including: 1. Smart cities and resilient environments; 2. Alternative/clean energy sources, energy distribution, distributed energy generation, and energy demand reduction/management; 3. Monitoring and improving air quality in built environment and cities (e.g., healthy built environment and air quality management); 4. Energy efficient, low/zero carbon, and green buildings/communities; 5. Climate change mitigation and adaptation in urban environments; 6. Green infrastructure and BMPs; 7. Environmental Footprint accounting and management; 8. Urban agriculture and forestry; 9. ICT, smart grid and intelligent infrastructure; 10. Urban design/planning, regulations, legislation, certification, economics, and policy; 11. Social aspects, impacts and resiliency of cities; 12. Behavior monitoring, analysis and change within urban communities; 13. Health monitoring and improvement; 14. Nexus issues related to sustainable cities and societies; 15. Smart city governance; 16. Decision Support Systems for trade-off and uncertainty analysis for improved management of cities and society; 17. Big data, machine learning, and artificial intelligence applications and case studies; 18. Critical infrastructure protection, including security, privacy, forensics, and reliability issues of cyber-physical systems. 19. Water footprint reduction and urban water distribution, harvesting, treatment, reuse and management; 20. Waste reduction and recycling; 21. Wastewater collection, treatment and recycling; 22. Smart, clean and healthy transportation systems and infrastructure;
