What factor impacts air movement in a building's design?

Building orientation plays a crucial role in influencing air movement within a building's design. The way a building is oriented can affect how wind interacts with it and the natural ventilation it receives. For instance, a building facing prevailing winds can be designed to maximize cross ventilation, allowing fresh air to flow through the space more effectively. Additionally, orientation determines how much sunlight enters the building, which can also impact thermal comfort and air movement inside.

By carefully considering building orientation, architects can enhance air quality, reduce reliance on mechanical ventilation, and create a more comfortable living environment. This factor is thus integral to sustainable design practices, aiming to optimize natural airflow and energy efficiency in the built environment.
