| description | This study aims to investigate the thermal performance of <i>PCM</i> and <i>PCM</i> combined with nighttime natural (NV) and mechanical ventilation (MV) applied to a residential building located in eight cities of tropical rainforest climate zone (Af). The analysis was accomplished using numerical simulations and developing a unique methodology for selecting the <i>PCM</i> melting temperature based on the thermal comfort limits. The thermal performance of the <i>PCM</i> integrated building was quantitatively evaluated using the concept of peak temperature drop. Additionally, a novel indicator of Total Temperature Drop (<i>TTD</i>) was introduced to determine the overall impact of the <i>PCM</i> and <i>PCM</i> combined with NV/MV on the thermal comfort conditions inside the building. The results showed that <i>PCM</i> 28 was the most efficient in improving the thermal performance of the building located in the Af climate zone, achieving a <i>TTD</i> of up to 356 °C per year. The usage of <i>PCM</i> 28 combined with nighttime natural ventilation improved the <i>TTD</i> values by up to 15%, whereas the integration of <i>PCM</i> 28 combined with mechanical ventilation resulted in a <i>TTD</i> values increase of up to 45%. Conclusively, mechanical ventilation showed its superiority over natural ventilation in the tropical rainforest climate, and <i>PCM</i> 28 applied together with mechanical ventilation could be used as the optimum combination for the whole climate zone. |
