The model area in ENVImet used for
the simulations of the “Green ground” and
“Green ground + Cool pavements” scenarios.
The red numbers identify four characteristic points
for which air temperature at 2 m above ground
has been considered in the study ....................................... 215
Fig. 7.6
Air temperature at 2 m above the ground
during one typical day (from 6 am to 6 am
of the day after) for each season at point 1 of the
pilot area modelled by ENVImet (asphalt car park
surface in front of a flat block). The differences
between the upper curve (the actual scenario “AsIs”)
and the other ones depict the UHI intensity
mitigation for the strategies described in the text .............. 217
