Thermal comfort is a critical component of indoor environmental quality in hot–humid climates, where building performance is strongly influenced by passive design strategies. This study evaluates the effectiveness of green architectural strategies in enhancing thermal comfort in four-star hotels in Nigeria. A qualitative descriptive approach supported by field measurements and structured observational analysis was adopted. Twenty (20) purposively selected hotels in Lagos, Abuja, Kano, and Kaduna were assessed using an observation checklist focusing on building orientation, shading devices, natural and cross ventilation, landscape integration, and green roof systems. Data were analyzed using descriptive statistics, Relative Importance Index (RII), and regression analysis. Findings show that building orientation and shading devices recorded the highest adoption (75%; RII = 0.75), followed by natural ventilation and landscape integration (70%; RII = 0.70), while green roofs were minimally adopted (20%; RII = 0.20). The overall adoption level was moderate, indicating partial integration of passive strategies. Regression results revealed a strong positive relationship between green architectural strategies and thermal comfort (R = 0.91; R² = 0.83), with the model statistically significant (F = 48.80, p = 0.002), confirming that 83% of thermal comfort variation is explained by strategy adoption. The study concludes that while passive design strategies enhance thermal comfort, their fragmented implementation limits performance. Integrated application is required to improve indoor comfort and reduce reliance on mechanical cooling in Nigerian hotels.
