This involved the brief theoretical analyses of the heat and mass transfer processes Keywords: and the energy balance equations applied to the roofs and most importantly, the dedicated measurement Green roof of the selected building roofs in Guangzhou (China), located at a typical sub-tropical climatic region. As a Thermal performance result, the temperature and air conditioning power consumption data within five selected testing rooms
