Influence of the Rustic Bamboo Envelope Construction Technique on the Thermal Performance of Vernacular Housing in the Ecuadorian Coastal Region: The Case of El Carmen-Manabí

Bamboo, particularly Guadua Angustifolia cane, offers significant thermal benefits for construction in warm, humid climates and has been a key material in Ecuador for over 9500 years due to its low cost, versatility, and low thermal conductivity. In the coastal region, including the settlement of El Carmen, traditional architectural techniques have evolved to incorporate local materials like Guadua cane. A common method involves using crushed cane as wall cladding, where longitudinally split bamboo is applied, creating openings in the structure. These openings, often viewed as a construction defect, influence passive cooling systems. This study investigated the impact of these irregularities on indoor thermal comfort by documenting the construction systems and climatic conditions of the area. Computational models were reconstructed and tested through CFD simulations to assess thermal behavior. The findings highlight the thermal implications of the vernacular construction system, revealing how wall openings affect passive cooling strategies and overall indoor comfort in the housing typologies of El Carmen.
