The objective of the study was to examine the architectural features of the building in relation to effectiveness of natural ventilation for middle income residential houses in Uyo Metropolis., Akwa Ibom State. Descriptive survey research design was used for the study. The population for the study consisted all middle income housing in Uyo metropolis. The instruments used for data collection were liquid crystal thermometers, wet and dry bulb hygrometer, anemometer, questionnaire and the CBE Thermal Comfort Tool (a computer model programme). The instrument was face and content validated by expert from test, measurement and evaluation while Crombach Alpha technique was used to determine the reliability of the instrument at 0.84 coefficient. Data obtained were analysed using Pearson Product Moment analysis. The findings of the study revealed that there is significant relationship between architectural features of the building and the effectiveness of natural ventilation and thermal comfort. It was recommended among others that buildings should be orientated with their longer sides intercepting prevailing winds and the shorter sides facing the direction of the strongest solar radiation. This will help avoid heat stress in the building.
