Abstract

Natural ventilation is considered as a passive energy-efficient strategy that could provide desired thermal comfort conditions for residents and improve the indoor space conditions. However, the aim of the present study is to analyze the potential of natural ventilation in reducing energy consumption for cooling of the building in summer. Therefore, the amount of energy consumption for ventilation and cooling of a single-story building in the four different climate zones in Iran has been evaluated by EnergyPlus. Afterwards, to evaluate the amount of the energy saving using natural ventilation, energy analysis has been performed for the reference building using a combined mode including natural ventilation and a mechanical cooling system. The considered climate zones include Tehran, Tabriz, Isfahan and Bandar-Abbas which are the most popular climate zones in Iran. The results show that the reduction percentage in energy consumption applying natural ventilation for Tabriz, Isfahan, Tehran and Bandar-Abbas are 18, 12, 10 and 3 percent, respectively. The highest percentage of energy saving is for Tabriz with a cold and dry climate and the lowest one is for Bandar-Abbas with hot and humid climate.
