Evaluating the feasibility of reducing cooling loads of tropical building using phase change material-based curtain

Abstract

Buildings in tropical climates have significant cooling demand due to high ambient temperatures and intense solar radiation, resulting in reliance on air conditioning and high electricity consumption, especially during peak daytime hours. This study explores the feasibility of reducing cooling loads in tropical buildings through the integration of phase change material (PCM)-incorporated screens. PCMs are capable of storing and releasing thermal energy during phase transitions, making them suitable for indoor temperature regulation. By integrating PCM into curtain systems, the material can reduce indoor heat, especially during peak hours (1100 hours to 1500 hours), when cooling demand is highest. This paper evaluates the effectiveness of this approach and investigates key factors such as PCM selection, climatic conditions and building system compatibility. The study aims to demonstrate how PCM-incorporated curtains can contribute to increasing the energy efficiency of tropical buildings.
