In some areas of high air condition adoption there is potential for night purge natural ventilation to reduce the number of hours that the air condition system is operated, leading to a reduction in energy usage and associated carbon dioxide emissions. In this study we examine the potential efficacy of such a strategy implemented in an office building located in Pune, India. Using a dynamic thermal model we have demonstrated that around 10% annual cooling load saving can be achieved. Results from an actual application of this strategy in Pune demonstrate that when conditions are beneficial significant precooling of the office space can be achieved before the occupied period, reducing the cooling load, saving energy, carbon emissions and costs.
