Performance evaluation of phase change material enhanced prototype in different climate zones

Abstract

Phase change material (PCM) technology, which efficiently stores thermal energy to maintain structures' inner atmosphere, is one of the most well established adaptive solutions to reduce air temperature variations in buildings. Passive heat modulation systems like PCMs improve thermal comfort and reduce building heating, ventilation, and air conditioning energy. Phase-change materials and thermal storage reduce energy use in building exteriors. This study modelled a tropical climate and found the optimal phase-change material thickness to improve thermal comfort and reduce cooling needs. Investigators focus on phase change materials for energy-efficient construction. This study compares the benefits of using PCMs in building envelopes. Four Indian cities in different climate zones were generalised using Energy Plus calibrated reference models. Three thicknesses of PCM HS-22 plasterboard - 5, 10, and 20 mm - and every possible air gap arrangement - 50 and 100 mm - were added to the wall's interior. This substance's 23°C melting point keeps a building's temperature close to its melting point during high-energy demand. The study found a strong correlation between material thickness, air gap, and energy performance index in all climate zones, with temperate regions benefiting most.
