Eficiencia isoterma de los modelos de ventilación exterior en patios de edificios residenciales. Estudio de casos

Abstract

Many buildings have been designed and built with courtyards to supply the light and healthy air demands to the dwellings. However, confined air quality in many of them is unhealthy for human use due to the diminished ability to renew the air. The purpose of the study is to catalog different models of isolated building courtyards under isothermal conditions, according to their dimensions. The goal is to quantify the efficiency of air exchange in each model and analyze the influence of size in controlled external conditions. In addition, current regulations in Spain are compared with the obtained results. In conclusion, the efficiency of ventilation ratio for courtyards in buildings depends on its design.
