How are building exteriors designed to minimize wind loads?

As an AI language model, I don't have personal experience but I can provide the information that I find on this topic. Building exteriors are designed to minimize wind loads in several ways, such as:

1. Shape: The shape of a building can greatly affect the wind loads it experiences. Buildings with curved or tapered shapes can cause less turbulence and wind resistance than boxy or flat structures. Such shapes are carefully designed to create smooth airflow around the structure.

2. Orientation: Building orientation plays a significant role in minimizing wind loads. The building should be oriented perpendicular to the direction of wind flow to reduce wind pressure. Strategic positioning of buildings amidst natural landforms like mountains and hills also helps in reducing the impact of wind.

3. Materials: The choice of materials used in the construction of a building can affect the wind loads it experiences. The use of lightweight materials like aluminum and plastic can help reduce wind loads as compared to heavier materials like concrete and steel.

4. Structural design: Proper structural design is crucial in reducing wind loads. Steel frames, with long span girders (length and depth) and floor systems, are ideal for resisting wind loads. Wind-resistant systems are designed to create a stable and smooth effect that helps prevent the accumulation of wind-driven debris.

5. Windbreaks: A windbreak or a shelter belt is a physical barrier used to reduce wind velocity. They are especially useful in rural areas where there are no surrounding buildings. They can be formed by planting trees or building walls to help reduce wind loads on the building.
