Tropical Bioclimatic Architecture: Passive Natural Cooling
Designing with Caribbean trade winds (alizés) drastically reduces reliance on energy-intensive air conditioning.
1. Catching the Trade Winds
Orienting living spaces along the East-to-West axis channels cooling eastern ocean breezes through adjustable aluminum or hardwood louvers (jalousies).
2. Deep Shading Overhangs (Varangues)
Expansive covered verandas shield perimeter exterior walls from direct solar radiation, preventing thermal mass buildup throughout the peak afternoon hours.
