During summer in India, temperatures often rise above 40–45°C, leading to extreme heating of buildings, especially those made with concrete and traditional construction materials. These materials absorb and retain heat throughout the day, causing indoor temperatures to become significantly higher than the outside environment., As a result, people living or working inside such buildings experience discomfort, sweating, and reduced productivity. In many cases, fans alone are not sufficient to provide relief, forcing increased use of air conditioners and coolers. This leads to higher electricity consumption and increased financial burden on households., This problem is more severe in urban areas where dense construction and lack of greenery contribute to the urban heat island effect, making surroundings even hotter. Buildings without proper ventilation, insulation, or reflective surfaces trap heat, making indoor environments uncomfortable even after sunset., The issue occurs very frequently during summer and affects a large population across residential homes, schools, and offices. Despite being a widespread problem, affordable and effective solutions are not widely implemented., This highlights the need for innovative, cost-effective solutions that can reduce heat absorption, improve ventilation, or provide passive cooling, making buildings more comfortable and energy-efficient during extreme summer conditions.
