Abstract
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.
