This study investigates the impact of traditional architectural design on energy efficiency in the coastal city of Gomishan, Iran. By analyzing the passive cooling potential of verandahs in Gomishan's vernacular houses, we aim to highlight sustainable architectural practices. Utilizing Olgyay’s bioclimatic chart, the thermal comfort levels of these outdoor living spaces were assessed. The area was divided into 85×85 cm grids to determine zones of thermal comfort, providing insights into the percentage of comfort area throughout different times and seasons. This research contributes to sustainable development by demonstrating how traditional designs can enhance modern energy-saving solutions.
