The article explores passive systems for regulating microclimates in residential settings, with a focus on modular constructions. It investigates the use of trombe wall system ventilation to ensure comfort and hygiene. study examines building designs that enable effective air circulation without using mechanical systems. Furthermore, effectiveness solar energy as device houses has been experimentally confirmed. Although research confirms this homes, there is limited documentation regarding its overall efficiency, particularly concerning impact surface pressure coefficient ventilation. establishes correlations governing thermosiphon collector’s at varying layer thicknesses. Optimal parameters, such maximum consumption (L = 120 m3h−1), are identified an thickness (δ) 100 mm outlet openings area (F) 0.056 m2. These findings pave way improving aimed maintaining optimal thermal conditions modern homes. suggest potential more efficient sustainable housing solutions. Further essential understand how factors like design wind speed affect efficacy.

The rapid urbanization of developing cities has intensified the challenge maintaining thermal comfort in buildings, particularly hot–humid climates. This study investigates impact floor level on airflow patterns and indoor temperatures multi-purpose mid-rise buildings Onitsha, Nigeria, where increasing urban density frequent power outages necessitate effective passive cooling strategies. Through a mixed-method approach combining empirical measurements, computational fluid dynamics (CFD) simulations, performance analysis, research examined variations ventilation rates temperature distributions across different levels six-story educational building over an annual cycle, focusing hottest (27 February), coldest (28 December), most windy (3 April), least (17 September) days. Results revealed distinct floor-level patterns: upper floors (fourth–fifth) achieved 39–40 air changes per hour (ACH) during hot periods while 30–35 degrees Celsius (°C); middle (second–third) showed moderate (15–22 ACH) but experienced heat accumulation (35–42 °C); lower reached 20 ACH conditions. Temperature stratification varied from 15 °C between entire peak conditions to 7 periods. Stack-driven contributed reductions up 3 °C, wind-driven promoted uniform distribution all levels. These findings informed floor-specific design recommendations: hybrid systems with automated controls, strategic architectural features including minimum area 15% for central atrium, comprehensive monitoring six sensors floor. provides evidence-based strategies optimizing tropical environments, valuable designing energy-efficient rapidly hot-humid
