Nowadays, researchers have conducted many studies about the role of natural ventilation as a passive cooling system. This would also help in reducing costs, excessive use of energy and the consequential environmental effects of year-round air conditioning. In this regard, energy consumption and Co2 emissions associated with buildings has a significant impact on the environment. The current research was carried out in Rasht with humid climate. The major aim of this study was to assess the role of natural ventilation on energy consumption optimization and reduce co2 emission over a year on a residential building. The exiting building have a two-story which the first floor was evaluated. The BEopt software was used for evaluation. The results showed that natural ventilation could reduce energy consumption by up to 3% and also reduce the co2 emissions more than up to 2.5%.
