Passive climatization using a cool roof and natural ventilation for internally displaced persons in hot climates: Case study for Haiti

► A low cost building solution for IDPs in hot climates is studied and simulated. ► Thermal conditions are improved with no use of HVAC system. ► Passive climatization systems allows increasing thermal comfort. ► Cool roof and natural ventilation increases thermal comfort up to 16%. ► The solution is simulated for Haiti Earthquake IDPs obtaining good results.
