Abstract

This study examines resource efficiency in residential buildings across Western Asia and Northern Africa (WN). The research addresses the pressing challenge of the residential sector's greenhouse gas emissions (GHGE) by evaluating strategies to enhance energy and material efficiency. The primary research question investigates how different scenarios can reduce operational energy use, material consumption, and related GHGE in residential buildings. Employing the ODYM-RECC framework, we developed a dynamic stock model using data from 850 residential archetypes spanning 19 countries. This model evaluated ten future scenarios, including six individual strategies and four combinations. The results indicate that a combined strategy could reduce use-phase emissions by 60 % and material-related emissions by 47 %, achieving an overall GHGE reduction of 56 % by 2050. These findings highlight the importance of integrated strategies addressing both construction practices and energy use to achieve substantial emissions reductions. Future research should focus on country-specific strategies and incorporate evolving regional policies and climate projections.

西亚和北非住宅建筑的未来资源效率方案：一项探索性研究

本研究考察了西亚和北非（WN）住宅建筑的资源效率。该研究通过评估提高能源和材料效率的策略，解决了住宅部门温室气体排放（GHGE）的紧迫挑战。主要的研究问题是调查不同的场景如何减少住宅建筑的运营能源使用、材料消耗和相关的温室气体排放。采用ODYM-RECC框架，我们利用来自19个国家850个住宅原型的数据开发了一个动态库存模型。该模型评估了10种未来情景，包括6种单独策略和4种组合策略。结果表明，综合战略可以减少60%的使用阶段排放和47%的材料相关排放，到2050年实现温室气体总排放量减少56%。这些发现强调了解决建筑实践和能源使用问题的综合战略的重要性，以实现大幅减排。未来的研究应侧重于具体国家的战略，并纳入不断发展的区域政策和气候预测。

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;
