The paper explores the performance of both passive and active cooling strategies in residential buildings to identify the most efficient methods for reducing indoor temperatures in tropical regions. Being a tropical country, Bangladesh faces a growing need for energy-efficient cooling solutions due to rising temperatures and increasing energy demands. In a humid subtropical region like Mymensingh, where warm and humid conditions persist, finding effective ways to maintain indoor comfort, while minimizing energy consumption is crucial. Through a more refined parametric analysis, additional techniques such as phase change materials and adaptive ventilation systems were evaluated. The findings reveal that a wellintegrated cooling system can significantly lower energy usage, while ensuring indoor comfort. Additionally, the study highlights the long-term implications of climate adaptation strategies and their role in sustainable urban planning. Passive strategies, such as optimized shading and improved air flow, proved to be highly effective in reducing heat buildup. Meanwhile, active cooling techniques, when used selectively, further enhanced thermal comfort without excessive energy consumption. These insights provide valuable recommendations for sustainable building practices in subtropical regions, emphasizing the importance of climate-responsive design. By adopting these strategies, residential buildings can achieve better energy efficiency, reduce dependency on mechanical cooling, and contribute to a more sustainable future. The study underscores the necessity of smart cooling solutions in mitigating the environmental and economic challenges posed by climate change.
The rising demand for cooling in residential buildings has prompted the need for innovative strategies that integrate both passive and active cooling methods.
