The sunny day experiences high solar radiation input, pushing maximum temperature to 38.6◦C and minimum 27.6◦C (Table 2).Under the intense energy regime, pronounced differences in ther-mal effect at the two blocks are expressed. The dry bare roof withhigh Bowen ratio cools down main by convective dissipation ofsensible heat (Gaffin et al., 2006). The diurnal records signify tem-perature divergence at the two blocks in heat gains and losses.
