The results for overlapping and non-overlapping interventions and for interventions overlapping current head reducing features appear logical. In some situations, old heat reducing features (like the shadow of building) might be slightly visible in color differences, but they result only in small differences (up to several degrees) as compared to the 6 °C PET-difference between two classes of heat stress. Users should understand the simplicity of the model and the fact that only rough estimations of heat stress reduction can be given as the effect of the interventions on the PET is also dependent on many local characteristics and situation of the people who should feel the difference in comfort temperature. Such local information is not available nor part of the PET map which is used as input for the PET in the AST.
