13.6.3 Evaluation of the Simulation Results
Below, the effects of the intervention tools described in the previous section will be
summarised briefl y.
Rows of Street Trees: Planting single and double rows of street trees results in
decreases local to each tree, both in terms of mean radiant temperature (MRT) and
in terms of predicted mean vote (PMV). With expansion of the canopy of the trees,
or by planting trees closer together, the distribution of these decreases tends to
become more linear.
As is shown by Figs. 13.12 , 13.13 , 13.14 , and 13.15 , rows of street trees typically
reduce predicted mean vote (PMV) value by 2, occasionally by 3. In our case this
means that while in the initial situation 80 % of pedestrians on the sidewalk feel
uncomforTab., after trees are planted this ratio is reduced to 10–30 %.
Planters In isolation, planters have little effect on the microclimate; however, they
exercise an undeniably positive effect on the streetscape and on the psychological
well-being of the population. In Bimbó út, planters appear in combination with rows
of street trees; here their effects cannot be clearly distinguished from the microcliFig. 13.11 Layout of modelling regions within the pilot area
