Common Case of Possibly Good Thermal Performance and Feasibility of the Extensive Green Roofing in the Buildings in Indian Subcontinent

Abstract

India is the largest and densely populated country in the world and with an increase in the population, the energy demand of the country also increases steadily. It is observed that houses located in Tamil Nadu region of India are not capable to provide thermal comfort throughout a year except for two months. In the present work behaviour of green roof (GR) as compared to the conventional bare roof (BR) is analysed for the building located at Central Tamil Nadu (at Trichy city area). The experiment was conducted for a green roof and a conventional bare roof. The temperature was recorded with the temperature sensors installed at different locations. There was 36% of the reduction in the total heat flux in the green roof while comparing it with the bare one.
