Abstract :
The main aim of this article is to offer a predictive method to determine the most significant values of a sky component on the floor of
circular or square courtyards of variable sizes under overcast sky conditions to be calculated quickly and precisely. Firstly, analytical
geometry is used to calculate the sky component on the floor of the courtyards under study considering the variable height/width ratios.
Empirical expressions are offered subsequently to fit the results obtained using analytical geometry, thus establishing the predictive
method.
