摘　　要：The building cooling load is calculated in most standards using the sol-air temperature(T_(sol-air)),which depends on the surface properties and the building configuration.This study presents an experimental and numerical analysis to find a relationship between the aspect ratio of the courtyard and the T_(sol-air) at different height levels.Besides,the influence of the surface reflection factor on the T_(sol-air) is analyzed.The results show that the T_(sol-air) inside the courtyard differs compared to the usual outside facade.This difference is increased by increasing the aspect ratio of the courtyard and can reach up to 60°C at low levels of the deep courtyards.It is also found that the courtyard geometry is much more important than the thermal behavior of the materials and the T_(sol-air) within the deep courtyard is less affected by the reflection factor of materials.
