Abstract: The objective of this paper is to study and analyse the local climate of Bhubaneswar and to assess the potential of using natural ventilation for arriving thermal comfort conditions in residential buildings. Various theories in response to Thermal comfort have been analysed to assess the thermal comfort of the city which has a very distinct hot and humid climate. Since natural ventilation is a key factor for achieving thermal comfort in hot and humid climate a typical mean monthly weather data has been selected from a 10 years weather data. The weather data are analysed on the basis of temperature, Humidity, wind speeds which are the key parameter for any typical Bio climatic chart. Thermal comfort models applicable for Bhubaneswar are used for assessment of thermal conditions. The study concludes that thermal comfort during night time can be achieved all most throughout the year by controlling the wind speed to 1-1.5m/s at least. Except the month April and May, in most of the months even it is possible to achieve Thermal comfort during the day time in Bhubaneswar. This study can also be used as a basis for developing strategies on naturally ventilated building forms.
