Local Thermal Improvement of Urban Climate with Evaporative Technologies

Evaporative technologies are used since decades in urban projects and contribute to re-design outdoor spaces. The research presents an experimental case study carried out in Rome during summer 2018 and presented in this paper. A very basic and cheap evaporative system is installed, then instrumental and subjective monitoring actions are carried out. The results show that air temperature drop up to 5°C Local Thermal Improvement of Urban Climate with Evaporative Technologies Michele Zinzi & Letizia Martinelli 100 can be achieved, as well as average drop above 3°C during the whole monitoring period. Also, the comfort perception is enhanced as demonstrated by the analysis of distributed and collected questionnaires.
