Abstract

Courtyard and building geometry are crucial aspects to achieve efficient natural ventilation and indoor thermal comfort in a compact urban environment. In this paper, first, a comparison between different geometries of courtyards in terms of wind flow characteristics and indoor air speed is performed based on the validation of Computational Fluid Dynamics (CFD) simulations with 2D published wind-tunnel experiments. Second, assessment of thermal comfort is made inside a number of selected dwelling's rooms facing different courtyard geometries. It was confirmed that rooms with cross ventilation have higher indoor air speeds as well as a cooler thermal condition than with single-side ventilation. The courtyard dimensions, the position of the room and the orientation are important aspects influencing both the indoor air speed and thermal comfort.
