Architectural ordonnance can be used to enhance the building's natural ventilation by considering the following factors:
1. Building orientation: Proper building orientation helps to maximize natural ventilation and reduce the need for mechanical cooling. When designing a building, the architect should ensure that the building is oriented in a way that allows for cross-ventilation and takes advantage of the prevailing wind direction.
2. Placement of windows: The placement of windows is crucial in enhancing natural ventilation. Windows should be strategically placed to allow for maximum air flow throughout the building. High windows placed on opposite walls can create a stack effect where cooler air enters the lower window, and warm air exits through the upper window.
3. Building shape: The shape of the building can also determine how well it can take advantage of natural ventilation. Buildings with a compact shape and central atriums tend to have better natural ventilation than those with long and narrow shapes.
4. Building materials: The type of building materials used can also affect natural ventilation. For instance, materials with high thermal mass like concrete can help to regulate indoor temperature by absorbing and releasing heat, thus promoting air circulation.
5. Landscape design: The surrounding environment can also affect natural ventilation. Landscaping can be used to direct wind flow towards the building, thereby enhancing natural ventilation. Trees can also be planted to provide shade and reduce the need for mechanical cooling.
