Lighting design in courtyards: Predictive method of daylight factors under overcast sky conditions

The main aim of this article is to offer a quick and precise predictive method for calculating the daylight factor for different points on the floor of square courtyards under overcast sky conditions. First, the calculation of the predictive method of the sky component is established based on earlie...
