The document discusses building design considerations for warm and humid climates. Warm and humid climates are characterized by high relative humidity between 70-90%, temperatures between 25-35°C in summer and 20-30°C in winter, and around 1200mm of annual precipitation. Passive dessicant cooling systems are recommended, which remove moisture from air by passing it through a desiccant material. This decreases humidity and the desiccant is then regenerated using solar heat. Building design should also focus on reducing heat gain through shading, maximizing cross ventilation to promote heat loss, and dissipating humidity to improve comfort.
