Learning Sustainable Design Principles from Old Sana Residential neighborhoods for adaptation to new Sana neighborhoods

Abstract

This research focuses on exploring the sustainable aspects embedded within traditional Yemeni architecture, specifically in the residential neighborhoods of the historic city of Sana'a. The study critically evaluates the sustainable features inherent in these architectural designs, encompassing the use of regional materials, adaptation to the local climate, and effective management of water consumption and waste recycling. The primary objective is to investigate and incorporate these sustainable techniques into contemporary Yemeni architecture and other regions with similar climatic conditions . The findings of this research highlight the successful integration of sustainable elements in traditional Yemeni architecture found in the old city of Sana'a. These architectural designs effectively employ regional materials, respond adeptly to the local climate, and demonstrate efficient practices in water consumption management and waste recycling. These sustainable elements have significantly contributed to the comfort and long-standing resilience of the city's residents. Furthermore, by adopting and adapting passive techniques utilized in the residential neighborhoods of old Sana'a, positive outcomes have been observed regarding temperature regulation, reduction in energy consumption, decreased CO2 emissions, and cost savings in building construction and maintenance . These techniques increased user comfort, with a temperature range of 15°C in winter to 30°C in summer. Energy use decreased by 84%, CO2 emissions decreased by 47.01%, and building costs were reduced by 32%. The implications of this research extend beyond the boundaries of Sana'a, Yemen, offering valuable insights applicable to other cities and regions facing similar climatic challenges. The study emphasizes integrating sustainable practices into architectural design and urban development, aligning with global sustainability efforts. By implementing these sustainable techniques, it is possible to address climate change concerns, conserve resources, and yield economic benefits. Moreover, this research underscores the potential of traditional Yemeni architecture and passive design strategies in enhancing environmental sustainability, energy efficiency, occupant comfort, and economic viability .This research highlights the potential for widespread adoption of these sustainable practices in Sana'a and other regions worldwide. Embracing these principles enables the creation of environmentally friendly, energy-efficient buildings while preserving cultural heritage and enhancing residents' overall quality of life.In conclusion, this research underscores the significance of learning from traditional Yemeni architecture and integrating sustainable design principles into contemporary building practices. By comprehending and implementing these principles, it is possible to develop sustainable, energy-efficient, and economically viable structures in Yemen and other regions facing similar climatic challenges. The findings of this research contribute to the global discourse on sustainable architecture and emphasize the urgency of incorporating sustainable practices for a more sustainable and resilient future.
