Thermal comfort optimization through bioclimatic design in Mediterranean cities

Background: Bioclimatic design is an approach based on local climate which improves thermal qualities and indoor comfort. Buildings follow this process to minimize negative effects the environment. However, still not suitable in developed countries. This study aims investigate Mediterranean bioclimatic strategies’ impact comfort efficiency housing, by examining architectural elements treatments. Methods: We adopted a descriptive, analytical, comparative methodology, complemented with software simulation, within qualitative quantitative approach. Investigation methodological tools were technical information including plans, elevations, photos, documentation. The consisted of multiple stages: literature review interpreting concept design, as well variables common building features. Moreover, paper showcases three examples successful passive houses. Furthermore, presents case- studyhouse Alex West, Alexandria, designed Revival style. Results: The results showed that most influencing features low-pitched roofs top chimney, achieved 12.6% 5% improvement summer 13% 6.8% winter, respectively. pergola porch barely had effect when placed northern façade. southern façade, positive contribution 1.4% 3.4% respectively reported, but slight winter 0.5% 2% respectively. Conclusions: We examined , compared between case-study Features focusing for cooling rather than heating, allowing wind flow maximized natural ventilation, using ventilated pitched roof spaces, sun shading proper facades angles, help regulation. proposes recommendations optimizing residential buildings Egypt.
