3. Results
The figure 3 shows the relative humidity values, the table 4 shows the air temperature values, the
table 4 shows the PMV values of the 6 scenarios. Even though in the temperature graph there is no big
change from one scenario to the other, in the relative humidity and in the PMV values the scenarios
with more shading devices show better values. The PMV has an improvement of few points. Which
means an improvement of the outdoor thermal comfort. However, scenario 3 also shows improvement
of the PMV in peak hours. In this scenario the vegetation is organized in the centre of the district and
the shading devices are the ones who surround the area.
The biggest reduction of the PMV is in the peak hours, between 10 am and 5pm. This are the most
critical hours of the day where walking in the outdoor conditions is not healthy due to extreme heat.
The study day as mentioned above is a typical summer day, 18 June 2019.
