Results and discussions

The total hourly values for incident solar radiation on building envelope is extracted from the result of simulations. In order to study on the impact of uncertainty in ground reflectance, the 1st to the 99th percentile of incident solar radiation for each hour of a day is presented in Fig. 6(Up).
This Figure is suitable for assessing the performance of different shading strategies, as it displays the frequency of occurrence based on the magnitude of the power.
