What is the average wind speed mentioned for tropical climates?

• A. 2 m/s
• B. 1 m/s
• C. 4 m/s
• D. 3 m/s

Answer: (A)

In tropical climates, wind-driven ventilation is a primary way to keep interiors cool, so designers use a practical reference value for typical air movement. About 2 meters per second represents a moderate breeze that reliably moves air through openings, supporting cross-ventilation and evaporative cooling without creating uncomfortable drafts. This speed helps explain how to size and place windows, doors, and other openings to maximize comfort when the wind is present. If wind speeds were much lower, ventilation would be insufficient to reduce indoor heat; if they were much higher, drafts could become uncomfortable. So 2 m/s is a commonly cited average because it balances effective cooling with comfort in tropical design.
