Due to emergency situations, many people are living under degraded conditions as displaced persons and refugees. Unfortunately, shelters commonly used in humanitarian context do not ensure comfortable conditions for their occupants. This study investigates the impact of utilizing passive climatization techniques on the indoor thermal comfort of the occupants in refugee settlements under Jordan’s climate using the Design Builder software. Several passive techniques were simulated, including orientation, floor, wall and roof insulation, and natural ventilation. The simulation results indicated that the thermal comfort has improved when using the aforementioned techniques by 9.72% offering 23% comfort hours throughout the year.
