Investigation of Airflow for Natural Ventilation in the Typical Medium-Rise Housing Cluster in South-Eastern Nigeria

Wind driven natural ventilation dependents on the microclimate conditions of its environment to thrive. In urban streets, it is influenced by the wind velocity and air temperatures factors. In this study, field experiments were carried out in selected streets of a typical medium rise housing cluster in southeastern Nigeria. The aim of the study was to understand the characteristics of air flow within this housing category, and to better examine the potentials of wind driven ventilation in this class of settlement. Wind speed and directions in the middle of selected streets were measured. Respectively, the undisturbed climatic conditions above the street canyon were recorded as well. The overall conclusion at the end of the study is that inside the streets, the potential of natural ventilation for both the single type and multi-branch type configurations is reduced, while that of continuous street configuration (without intermediate intersections) provided a higher potential for natural wind driven ventilation. This is attributed to the internal interferences and reduction of the wind speeds inside the street canyons. Generally, universal meteorological information gotten from unobstructed areas in cities are used in the design of buildings, thus the significance of this study outlines the importance of obtaining microclimatic information in pre-design stages.
