The 5th Conference on “Urban Planning and Architectural Design for Sustainable Development” (UPADSD), follows the success of previous versions in 2015, 2017, 2018. It is concerned with the concept of sustainable development and the different approaches that have become essential to modern development and energy efficiency. To be a sustainable city, it must be designed with consideration of the environmental impact, for example, decreasing traffic congestion and using sustainable materials in constructions. A commitment to sustainable architecture encompasses all phases of a building including the planning, building, and restructuring. Sustainable development is the development that meets the needs of today and doesn’t adversely affect the future generations.
