The application of Bioclimatological indices is very useful for the evaluation of outdoor thermal comfort in various configurations of space/landscape. It has been observed that this configuration can improve the human thermal sensation. Six configured sites in Agricultural University of Athens Campus (AUA) that were studied in this publication differ on the percentage and the type of green coverage and on the Sky View Factor (SVF) value. The widely known indices, Humidex and PET (Physiological Equivalent Temperature), were applied to evaluate the bioclimatic performance of those sites.
