Abstract

In dense urban areas, reducing traffic and increasing green areas is foreseen as a way of promoting urban comfort. Using the urban requalification project for Lisbon’s Avenidas Novas neighbourhood as a case study, the effects of vegetation on microclimate and urban comfort are evaluated. In this context, the ENVI-met software is used to model the present and the future urban scenario. The simulation results indicate: i) increased urban comfort in the morning and in the afternoon resulting from the decrease in temperature due to the presence of new green areas foreseen by the urban project; ii) a reduction of up to 3 degrees in the morning (9h) and up to 3 degrees in the afternoon (15h); iii) the model implemented in ENVI-met suits the urban and environmental characteristics of Lisbon and it is, therefore, desirable that future urban rehabilitation projects should consider ex ante simulation of this type.
