India is the seventh-largest country in the world and ranked second with more than a billion populations after China. The annual electricity consumption demand increased to 8% in the buildings for residential and commercial sectors. The requirement of thermal comfort is a primary need in residential buildings located in composite and hot-dry climates. The thermal performance of cool roof model was analyzed in terms of indoor temperature compared to Reinforced Cement Concrete (RCC) roof for composite climate, Indore, Madhya Pradesh, India. The study aims to assess the impact of the cool roof on the indoor temperature of buildings. The experimental study indicates that a cool roof performed better for indoor temperature profile and maintains a thermal comfort in buildings. The cool roof technology is more economical and easy to implement in all residential and commercial buildings. The study revealed that the roof's interior and exterior surface temperature reduced about 4.1 °C and 9.2 °C, respectively, while indoor room temperature reduced about 2.4 °C. |
