Cas de la ville de Ouargla Auteur(s): DJEDDOU Boutheina Résumé: Energy demand in urban areas is increasing due to rapid population growth, Saharan cities are no exception, where urban development is accelerating, leading to an increase in energy consumption. In hot and arid climates, energy demand increases further. In order to assess the energy efficiency of housing in arid areas in Algeria, this study focuses on three types of neighborhoods in Ouargla with different urban densities. A field survey was conducted using questionnaires to assess the quality of outdoor thermal comfort in the streets and its influence on the interior of buildings, as well as on energy consumption in Ouargla. The aim is to design a sustainable and energy-efficient urban environment. Urban form is considered as the key parameter that most influences the energy efficiency of buildings in a hot and arid climate. This study aims to assess the impact of urban form on the energy consumption of buildings. The selected neighborhoods were simulated using DesignBuilder software using climate data specific to the city of Ouargla. Different parameters were studied at both urban and architectural scales. Urban characteristics, urban form expressed by the H/W ratio and orientation, also the style of the dwelling; construction materials, U-value and wall thickness as architectural features. This study focused on the summer season and revealed that in addition to the building envelope; urban form has a significant impact on energy consumption, the more compact and denser the form is the month is the energy consumption.

The study highlights the richness and diversity of architectural styles, characterized by colonial influences, while identifying the challenges related to their conservation within a rapidly changing urban context. Through a multidisciplinary approach combining documentary analysis, urban planning studies, field surveys, and investigations involving the local population and institutional stakeholders, the research reveals a critical state of vulnerability for this heritage. This situation is exacerbated by the absence of a dedicated Land Use Plan (POS) for the historic center and a lack of tailored conservation and valorization policies. The study also sheds light on ambivalent perceptions within the local community, often influenced by the connection of this heritage to the colonial period. However, there is a growing recognition of the historical and architectural value of this heritage among residents and some institutional actors. The thesis concludes that an in-depth understanding of this heritage is essential to raise awareness among stakeholders about its significance and to guide public policies towards better conservation and valorization. It offers concrete recommendations to integrate this heritage into the sustainable urban development of Setif, thereby contributing to its patrimonial recognition and inclusion in a long-term preservation strategy.

Investigating Biskra city, in Algeria, as a case study. It examines how external building materials, and street geometry affect pedestrian level thermal conditions. The research aims to provide evidence-based guidelines for sustainable urban planning in arid cities. By investigating the localized effects of building materials and street orientation, which have been largely underexplored in previous research, the study bridges critical knowledge gaps. A comprehensive literature review highlights the need for context-specific studies to better understand the interactions between urban geometry and building material properties in regions with extreme weather conditions. Field data collected in Biskra city, including air temperature and relative humidity, validated via ENVI-met simulations modeling with various street orientations (East-West and North-South), height-to-width ratios, and building materials parameterization (brick, concrete, adobe, and limestone). Therefore, deeper street canyons reduce surface temperatures but are less effective in mitigating thermal stress in East-West orientations, emphasizing the dominant role of street alignment. Complementing these findings, limestone as crucial material demonstrates optimal thermal performance, offering high cooling efficiency, particularly in North-South streets, through its reflective properties, which help retain less heat. However, building material choice has strong relationship to street orientation. Thermal comfort indices, such as Physiological Equivalent Temperature (PET), further validate these findings, with North-South streets achieving significantly lower PET index values. In conclusion, this thesis provides practical urban design guidelines, highlighting building materials selection and North-South street orientation as key components of a comprehensive strategy to enhance outdoor thermal comfort. The findings support sustainable urban planning by mitigating Urban Heat Island (UHI) effects, improving public health, and boosting urban resilience. Description: Projet Urbain 2025-01-01T00:00:00Z
