Sustainable Dwelling Design Principles in Libya: Strategies for Eco-Friendly Architecture

This study explores how Libyan building construction incorporates environmental design principles for energy efficiency and sustainability. Libya struggles with sustainable development due to its fossil fuel dependence, water scarcity, and extreme weather patterns. Traditional Libyan architecture, such as that found in Ghadames, has used passive cooling and sustainable design, but modern construction relies on energy-intensive mechanical systems, increasing consumption and environmental impact. This research examines architectural methods to improve energy efficiency, thermal comfort, and building sustainability in Libya's hot and arid climate. The methodology consists of a comprehensive literature review and an analysis of two case studies: traditional dwellings in Ghadames and a sustainable international building in Saudi Arabia selected for its similar climate to Libya. The case studies were assessed based on energy usage, thermal performance, and sustainability. The findings indicate that traditional architecture in Ghadames, with its passive cooling techniques, thick walls, and use of locally available materials, provides superior thermal comfort and energy efficiency compared to modern buildings. The international case study demonstrates how renewable energy systems and advanced sustainable design techniques can be integrated to enhance energy efficiency and sustainability. The study emphasizes the advantages of adopting sustainable building design practices in Libya. Embracing sustainable practices not only conserves energy and reduces carbon emissions, but also improves occupant comfort and supports sustainable development. The research highlights the need for modern Libyan architecture to incorporate traditional design principles into contemporary technologies to address environmental challenges effectively.
