Evaluación de propuestas de diseño para determinar una distribución eficiente de superficies de arboleda/superficies selladas en plazas urbanas

Abstract

The paper aims to evaluate different design alternatives to determine an efficient distribution of the optimal proportion of green areas of woodlot and sealed areas in urban squares. In former researches has been concluded that this proportion is 60% woodlot- 40% sealed. In order to evaluate the thermal conditions, 12 scenarios with different distributions of woodlot and sealed areas were simulated. ENVI-met software was used to simulate thermal behaviour and COMFA method to determine comfort conditions. The results show that the most effective scheme is 60% of woodlot around a sealed centre with an area that does not exceed 20% of the square surface. Another effective alternative is the one concentrating 60% of woodlot at the centre of the area. These findings highlight the importance of an adequate relation between the proportion and distribution of woodlot / sealed areas to improve thermal performance and comfort conditions of open spaces.
