Green Architecture as a Concept of Historic Cairo
Traditional architecture of Historic Cairo demonstrates significant potential for enhancing thermal comfort in hot arid climates through passive design methods. This study highlights that the El-Suhaimi house, a historic structure, offers sustainable solutions applicable to modern green architecture. By analyzing this case study using Design Builder simulation software, researchers confirmed its environmental adaptability and local identity. The findings suggest that integrating elements from historic Cairo's architectural style can inform contemporary green building practices, providing a model for environmentally conscious urban development in similar climates.
Searching for Urban Patterns; An Assessment of Historic Edges and Its Surrounding Context: Historic Cairo as a Case Study
Historic Cairo exhibits repetitive spatial, architectural, and land-use patterns along its urban edges, which create distinct barriers influencing surrounding activities. These patterns suggest potential for learning from successful interventions applied to similar configurations, regardless of cultural or contextual differences. The study develops a quantitative analytical framework capable of measuring micro and macro-level spatial configurations, revealing cause-and-effect relationships between edge structures and their surroundings. This method enables targeted urban planning strategies that leverage identified patterns to enhance intervention success within historic city fabrics.
Integration of Static and Dynamic Spaces in Historic Cairo: A Community Spirit that May Vanish
Historic Cairo's streets, renowned for their intimacy and walkability, are threatened by rapid socio-cultural changes that disrupt the balance between static and dynamic urban spaces. The study reveals that the integration of these spaces—defined by enclosure degree, wall thickness, opening width, and activity nature—is crucial for fostering community spirit and behavioral needs. Through observation, researchers analyzed how variations in these factors influence urban dynamics, highlighting the vulnerability of this centuries-old town to modernization pressures.
