Descripción
This paper describes different ways of reducing urban air temperature and their results in two cities: Campinas - Brazil- a warm temperate climate with a dry winter and hot summer (CWa), and Mendoza- Argentina -a desert climate with cold steppe (BWk)-. A high-resolution microclimate modeling system -ENVI-met 3.1- was used to evaluate the thermal performance of an urban canyon in each city. A total of 18 scenarios were simulated including changes in the surface albedo, vegetation percentage and the H/W aspect ratio of the urban canyons. These results revealed the same trend in behavior for each of the combinations of strategies evaluated in both cities. Nevertheless, these strategies produce a greater temperature reduction in the warm temperate climate (CWa). Increasing the vegetation percentage reduces air temperatures and mean radiant temperatures in all scenarios. In addition, there is a greater decrease of urban temperature with the vegetation increase when the H/W aspect is lower. Also, applying low albedo on vertical surfaces and high albedo on horizontal surfaces is successful in reducing air temperatures without raising mean radiant temperature. The best combination of strategies - 60% of vegetation, low albedos on walls and high albedos on pavements and roofs and 1.5 H/W- could reduce air temperatures up to 6.4 ºC in Campinas and 3.5 ºC in Mendoza.
