The present building of college convention center posing the problem of improper ventilated and heated atmosphere in most of its parts during large gathering programs. Major part of the building exposed to the sun the roof being heated throughout the day. The additional heat gain is adding up from occupants, light appliances etc. Since there is no provision for the exhaust, it is posing the problem of heated air inside the building. Making the people sweat and suffocate due to lack of fresh or sufficient air circulation. Looking at the climatic zone and the use of convention center for few hours in a day over few days in a year. This paper includes inspection and evaluation of convention center building for establishing balanced thermal atmosphere and improving air quality that satisfies the majority of occupants. Different techniques and methods of building cooling like air cooler and wind turbo rooftop air ventilators are considered. It is proposed to go for low cost natural rooftop ventilation supplemented with additional fans or air coolers at strategic points for improved ventilation and thermal comfort for occupants. Following the concepts of passive cooling techniques or adopting retrofits reduces heat generation and energy consumption.
