To achieve this, an integrated approach in the TRNSYS software validated in previous studies was used. The obtained results highlight firstly, how the microclimate near Raid has an impact on the energy needs, which can be negative in summer when the cooling needs can increase by about 42% and positive in winter when the heating needs can decrease by about 32%. In a second phase, findings highlighted that the impact of solar radiation interreflections generated by the courtyard on building cooling and heating energy needs is relatively low. In contrast, the interreflections generated by a street canyon have a negative impact on the cooling energy needs by increasing them up to about 34%. While the heating needs can be reduced by up to about 42%."
