Resumen:
The characterization of urban radiant fields is fundamental information to assess energy consumption’s increase and environmental pollution associated to urbanization phenomenon. Starting from this analysis and diagnosis, it is possible to develop a strategic planning of the city’s growth.In this study, the reference case is Mendoza Metropolitan Area (MMA) located in a seismic and semiarid zone. The urban model presents wide road channels and different tree species along the streets in opposition to the compact city model.This paper evaluates the impact on the (SVF) that is produced by the combination of different buildings densities (high, medium and low) and diverse magnitudes of the forest species (first, second and third); and their impact on thermal conditions in different seasons (summer and winter) of the year. A computational tool has been developed to obtain the value of the (SVF) from digital hemispherical photo image processing.The results show that if the building density remains constant, the use of first magnitude tree species restricts the possibilities of upgrading the thermal conditions of urban canyons, during both summer and winter; showing the most favourable configuration differences in temperatures that do not exceed 2 ºC in relation to  the worst condition. Key words: Sky View Factor (SVF), urban canyon, building density, urban forest, seasonally thermal behaviour.
